Aiming for both Structural Integrity and Historical Accuracy

The Gato-class fleet boat USS Cobia (SS-245), a WWII museum sub in Manitowoc, Wisconsin, is heading to Fincantieri in September to undergo essential dry dock maintenance for the first time since 1996. Credited with having sunk a total of 16,835 tons of Japanese shipping across four war patrols, the dry docking will address maintaining her structural integrity.

However, when it comes to restoring and maintaining the historical accuracy of these old fleet boats, the USS Cod museum has been hard at work experimenting with Cobia with in manufacturing replica period submarine parts that have been missing from these vessels for decades.

That’s when 3-D printed replacements come into play.

The only submarine museum in Africa has reopened

The French-built Daphne-class submarine SAS Johanna van der Merwe (S99) was ordered in 1967 by South Africa for use by the SAN, one of 26 of Daphnes constructed during the Cold War for service in six different fleets around the world.

Commissioned in 1971, “JDM” gave lots of shadowy and unsung service during the assorted “Bush Wars” in the 1970s and 80s in which South Africa was a proxy for the West against the Soviets in Angola and Mozambique.

She reportedly took part in at least ten clandestine special operations, dropping commandos behind enemy lines. However, Söderlund details at least 11 commando runs by JDM as: Op Extend (June 1978), Op Lark 1, Op Bargain (January 1979), Op Artist (February/March 1980), Op Nobilis (July 1984), Op Legaro (September 1984), Op Magic (March 1985), Op Argon (May 1985), Op Cide (February/March 1986), Op Drosdy (May/June 1986), and Op Appliance (May/June 1987).

Kept in operation somehow despite layers of embargoes, she outlasted the Apartheid era in South Africa and was renamed SAS Assegaai in 1997 with the change in government in Jo’Burg.

Decommissioned in 2003 after a 32-year career, her three sisters in SAN service were cut up for scrap, but a shoestring operation over the past 22 years has finally saved her. While she spent a few years as a floating museum before closing to the public in 2015, the “Silent Stalker” is now preserved on shore in Simon’s Town.

Above we see the Gato-class fleet boat turned submarine radar-picket USS Ray (SSR-271) in Hong Kong Harbor while on her way home from her 1956 6th Fleet deployment. During WWII, she was a menace to the emperor’s fleet, running up a tally of 155,171 tons across eight war patrols.

However, she was also one of the most impressive lifesavers of the conflict.

The Gatos

The 77 Gatos were cranked out by four shipyards from 1940 to 1944 for the U.S. Navy. They were impressive 311-foot-long fleet boats, diesel-electric submarines capable of extended operations in the far reaches of the Pacific. Able to swim an impressive 11,000 nautical miles on their economical power plant while still having room for 24 (often cranky) torpedoes.

A 3-inch deck gun served for surface action in poking holes in vessels deemed not worth a torpedo while a few .50 and .30-cal machine guns provided the illusion of an anti-aircraft armament. Developed from the Tambor-class submarines, they were the first fleet boats able to plumb to 300 feet test depth, then the deepest that U.S. Navy submersibles were rated.

Meet Ray

Our subject is the first U.S. Navy warship named for the flat-bodied, whip-tailed marine cousin of the shark. She was one of the “Manitowoc 28” submarines (10 “thin-skinned” Gatos with a test depth of 300 feet and 18 thicker follow-on Balaos) constructed by the Manitowoc Shipbuilding Company of (wait for it) Manitowoc, Wisconsin between 1942 and 1945.

With all 28, initial sea trials were done in Lake Michigan then the boats were sent down the Mississippi River (via the Chicago Sanitary and Ship Canal, then the Des Plaines and Illinois Rivers to the “Mighty Miss”) to New Orleans, a freshwater trip of just over 2,000 miles, for completion and fitting out.

Gato-class submarine USS Peto (SS-265) side launched at Manitowoc

Laid down 20 July 1942, Ray launched 28 February 1943, just a month after sister USS Raton (SS-270) and a month before USS Redfin (SS-272). Ray’s sponsor was the wife of Capt. Sam Colby Loomis, Sr. (USNA ’02) and mother of then LCDR Sam Loomis, Jr. (USNA ’35), the latter one of the most decorated sub skippers of WWII.

Ray commissioned 27 July 1943 and her plank owner skipper was CDR Brooks Jared Harral (USNA ’32), a New Yorker by way of New Orleans who had learned his trade on the cramped “Sugar Boat” USS S-17 (SS-122) earlier in the war, carrying out seven short war patrols in the Panama and Caribbean area.

Ray on Great Lakes sea trials

After six weeks motoring around Lake Michigan in light conditions in the summer of 1943, she departed the Lakes on 15 August, bound for the Big Easy, where she arrived a short week later, propelled by the Mississippi. Loading stores and torpedoes there, she left for Coco Solo, Panama, on 26 August, then spent five weeks training in those tropical waters for her war in the Pacific.

Deemed ready for combat, she left Baltra Island in the Galapagos on 9 October, bound on a 7,800-mile direct trip for Brisbane.

War!

Arriving in Australia on 30 October 1943– just three months after her Manitowoc commissioning– a fortnight later, Ray departed from Milne Bay, New Guinea for her 1st War Patrol, ordered to stalk Japanese shipping north of the Bismarck Archipelago. For 60 percent of her crew, it was their first war patrol on any submarine.

On the early morning of 26 November, she sank the Japanese army Shinkyo Maru-class auxiliary transport Nikkai Maru (2562 GRT) south-west of Truk, with the vessel breaking apart into three pieces and sinking. For this, Ray suffered her first depth charging in return.

A few hours later, she pressed an attack on a ship of some 10,000 tons and reported a sinking. This could be the 2,700-ton auxiliary water carrier Wayo Maru, which was sailing with Nikkai Maru but arrived at Truk on 28 November with no damage.

In her attacks, Ray expended 10 torpedoes for seven claimed hits, which is rather good for American fish at this stage of the war. Recalled for operational reasons, Ray completed her 1st patrol on 7 December 1943, returning to Milne Bay after covering 7,479 miles in 24 days. She was credited with sinking two freighters of 9,800 tons and 4,500 tons, respectively.

Ray departed Milne Bay on her 2nd War Patrol on 11 December after a three-day turnaround alongside the tender USS Fulton, ordered to patrol in the Banda Sea.

On the overnight of 26/27 December, she stalked, then torpedoed and sank the Japanese fleet tanker Kyoko Maru (5800 GRT, former Dutch Semiramis) in the Tioro Strait 14 miles northwest of Kabaena Island. She broke in two and sank, carrying 41 passengers and crew to the bottom along with 7,500 tons of crude oil cargo.

The six-torpedo attack left a “huge billowing column of orange flames” some 75 feet wide that “mushroomed out like a thunderhead as it rose hundreds of feet in the air.”

From Ray’s patrol report:

On New Year’s Day 1944, Ray celebrated by sinking the Japanese auxiliary gunboat Okuyo Maru (2904 GRT), towing a landing craft some five miles from the mouth of Ambon Bay, with three torpedoes, killing 135 passengers and crew.

Three days later, she attacked two Japanese cargo ships in the Savu Sea just off Timor with four torpedoes, reportedly damaging one of them.

On 12 January, Ray ended her 2nd war patrol at the big Allied sub base at Fremantle, completing 7,007 miles in 46 days. She was given credit for sinking a 10,020-ton AO (Sinkoku type) and a 7,886-ton auxiliary.

Having steamed over 25,000 miles since leaving her builders six months prior, Ray was allowed a full three-week turnaround time before she left on her 3rd War Patrol on 6 February 1944.

Ordered to patrol in the Java and South China Seas, she also carried a cargo of mines to sow off Japanese-occupied Saigon, French Indochina.

Working close to shore, she grounded in the shallows on 17 February but was able to float free with the tide and the next day shrugged off two near-miss bombs dropped from a Japanese Rufe (Nakajima A6M2-N) floatplane. She dodged three more on 24 February.

Coming across a nine-ship convoy on the night of 2/3 March in the South China Sea, she fired four torpedoes, claiming a damaging hit on a 10,000-ton tanker and suffering a “severe” depth-charging in the process.

She ended her patrol back at Fremantle on 27 March after 51 days, covering 10,688 miles.

Her 4th War Patrol started on 23 April, ordered to range south off the Davao Gulf in the Philippines.

Haunted by Japanese land-based Betty bombers (Ray logged 71 aircraft contacts on the patrol), she birddogged several small enemy convoys but couldn’t line up an attack– that was until she found a “well disciplined” large convoy (Convoy H-26) of six escorts (with some emitting radar signals) covering eight Marus and a tanker on the afternoon of 21 May. Just after midnight on 22 May, she had lined up on the largest targets, the Japanese army tanker Kenwa Maru (6384 GRT) and the cargo ship Tempei Maru (6097 GRT), firing six torpedoes that damaged the former and sank the latter. Tempei Maru blew up and went to the bottom with a cargo of rice and gasoline, along with 35 crew and passengers.

The next day, teaming up with sister USS Cero, she sank the freighter Taijun Maru (2825 GRT) carrying a cargo of Daihatsu landing barges.

She made four radar-assisted night attacks on the convoy in all, firing 18 torpedoes in two successful runs, and claimed six kills.

Then she came across a Japanese cruiser task force on the afternoon of 31 May that she continued to track but could not attack for the next two days. However, she did get ineffectively strafed by one of the cruiser’s floatplanes for her efforts.

Wrapping up her 4th War Patrol at Fremantle on 14 June, she was credited with 42,000 tons of shipping, roughly three times what she bagged, but hey, it’s war.

With that, LCDR Harral was pulled from Ray and bumped upstairs to COMSUBPAC staff. In his four patrols on our boat, he had earned the Navy Cross, two Silver Stars, and two Bronze Stars, so it’s safe to say he deserved the promotion.

His replacement was Keystone stater LCDR William Thomas Kinsella (USNA 1935), late of the old (had been laid up in 1931) USS O-8 (SS-69), a training boat out of New London.

Kinsella took the repaired Ray out on her 5th War Patrol (his first) from Fremantle on 9 July, headed to patrol in the South China Sea.

He proved a fast study and sank three Japanese tankers– Jambi Maru (a.k.a. Janbi Maru and Jinbi Maru) (5244 GRT, former Dutch Djambi), Nansei Maru (5878 GRT, former British Pleiodon), and Taketoyo Maru (6964 GRT)– as well as two cargo ships– Koshu Maru (2812 GRT) and Zuisho Maru (5286 GRT) over the next month. The Koshu Maru was a particularly sad footnote, as she was packed with 1,500 Javanese laborers destined to repair the Japanese airfield at Makassar, and 540 other passengers, with most perishing as she disappeared below the surface in just two minutes.

The chase for the unescorted Jambi Maru was almost pyrrhic, with Ray firing 22 torpedoes (!) in six attacks to get eight hits on the tanker– a move that forced the sub to return to Australia mid-patrol to quickly grab more fish and head out for more havoc.

She ended her extraordinarily successful 5th War Patrol at Fremantle on 31 August 1944, completely out of torpedoes (going through 46!), capping 14,237 miles underway in 67 days.

She was credited with four “kills” totaling 36,400 tons.

On 23 September 1944, Ray departed Fremantle to begin her 6th War Patrol, ordered again to the South China Sea where she had been so busy the month before. Setting off for the waters around the Japanese-occupied Philippines with 16 Mk 14-3A torpedoes loaded forward and eight newer Mk 18 electric fish loaded aft, it would be one of her most historic sorties.

On 12 October, she sank the Japanese troop transport Toko Maru (4180 GRT) near Cape Cavalite, Mindoro, and ate 30 depth charges in return.

Two days later, a hatch inadvertently left open while submerging ended up flooding two-thirds of the control room. While she suffered mechanically from this– and was forced to call on the services of the tender USS Orion at Mios Woendi for five days of emergency repairs– she had no casualties.

On 1 November, Ray sank the Japanese coastal tanker Horai Maru No.7 (834 GRT) west of Mindoro, then completed a “special mission,” typically code for landing agents or supplies to resistance groups. Post-war, it was known that this mission saw a landing party sent ashore on the west coast of Mindoro to recover two Naval Aviators that had been shot down during carrier raids and rescued by Filipino insurgents, along with two U.S. Army officers that had been fighting with the guerillas since 1942, and a local escaped political prisoner.

Three days later, operating in a Yankee wolf pack with USS Bream, Guitarro, and Raton, the pack came across Convoy TAMA-31A and shared in sending the big Japanese transport ship Kagu Maru (6806 GRT) to the bottom off Dasol Bay, Philippines, with Ray delivering the coup de grace by blowing off the damaged ship’s bow with two torpedoes.

On 5 November, lookouts from the submarine USS Batfish spotted Japanese Convoy MATA-31, some 15 ships with air cover, heading from Manila to Formosa. The convoy included six freighters, two kaibokan frigates, and five subchasers, while the heavy cruiser Aoba and famed Mogami-class heavy cruiser Kumano were riding along for good measure. Batfish tried to get in an attack on Aoba but came up short. She nonetheless passed on the contact, and Ray’s wolfpack made ready to receive.

Cruiser Kumano, circa Oct 1938, as seen in the U.S. Navy Division of Naval Intelligence’s A503 FM30-50 booklet for identification of ships

The next day, while off Cape Bolinao, Luzon, the four waiting American submarines concentrated on Kumano and would fire an amazing 23 fish at the big 14,000-ton bruiser.

Two hits– one blowing off her bow section and the second flooding her engine rooms– left Kumano dead in the water with an 11-degree list. However, with the swarm of aircraft keeping Ray deep during daylight hours, and the swarm of escorts too tight once she surfaced after dark, Kinsella found himself presented with a dream target– but one he could not claim. Kumano, towed to Dasol Bay by the freighter Doryo Maru, would be finished off in Santa Cruz harbor less than three weeks later by carrier aircraft from USS Ticonderoga.

Operating independently, on 14 November, Ray sank the Japanese corvette Kaibokan CD-7 (745 tons) about 65 nautical miles north-west of Cape Bolinao while the vessel was escorting Convoy MATA-32. She was sent to the bottom with 156 men. The sub followed up on this by sinking the transport Unkai Maru No. 5 (2,841 GRT) from the convoy seven minutes later.

On 19 November, Ray performed lifeguard missions, scooping up Lt. James Arthur Bryce, USNR, of VF-22, from the drink off Cape Bolinao. A young fighter pilot flying from USS Cowpens (CVL-25), his F6F-5 was damaged by anti-aircraft fire while attacking a Japanese convoy. Bryce would pick up a DFC for his actions that day, adding a second one to his salad bar in January 1945 for downing three enemy aircraft in the same sortie. Sadly, this ace (he ended up with 5.25 victories) was killed in an accident soon after.

Ending her 6th War Patrol on 8 December at Pearl Harbor via Midway with a waterlogged Lt. Bryce aboard, Ray covered a lucky 17,777 miles in an exceedingly long 98 days, firing all 16 of her Mk 14-3A torpedoes. She was given credit for 6.5 kills (sharing Kumano) for a total of 35,100 tons.

This brought her running tally sheet to 20.5 kills for 146,206 tons.

Following a much-needed refit and overhaul at Mare Island Navy Yard– which allowed her crew to spend Christmas stateside, Ray only made it back to “the line” in April 1945, at which point she was in a quite different war.

USS Ray, Mare Island 9 March 1945

With Japanese convoys no longer abundant on the high seas, her 7th War Patrol, off Kyushu in Japanese home waters and in the Yellow Sea, would be one of surface engagements against small craft that didn’t rate a torpedo.

Departing Guam on 30 April 1945, she capped this patrol at Midway on 16 June, having traveled 14,463 miles. In that interval, she had made 46 surface contacts in the Yellow Sea, with about a quarter of those being other American submarines patrolling the same area.

The rest were small coasters and trawlers– which she was determined to destroy.

Throughout 21 gun attacks, most at night, she expended 815 rounds of 40mm and 137 rounds of 5-inch, accounting for 19 small craft (two sea trucks, two small patrol boats, 15 four-masted rice schooners) carrying supplies between Japan and Korea for a total of 6,000 tons. She also encountered 24 mines, exploding or sinking most via gunfire.

However, her most important piece of work during this patrol was in two large rescues while spending 11 days on a lifeguard station off Japan. In one week, she pulled aboard 20 aviators, 10 from an Army B-29 and 10 from a Navy PBM Mariner. As noted by COMSUBDIV 141, “This second rescue was a particularly beautiful piece of work, being conducted at night in heavy seas and in close proximity to rocks and shoals.” Ray transferred the rescued crews to USS Lionfish and Pompon and continued her patrol.

In all, 86 American submarines spent 3,272 days on life guard duty during the war, with the bulk of that time (2,739 days) in 1945 when the conflict moved to the Japanese home islands. They rescued 504 men from the sea. Ray was the second most prolific life guard sub with 23 recoveries, just behind USS Tigrone, which had an impressive 52, the latter largely due to spending most of two patrols on such duty.

Ray’s 8th War Patrol, beginning on 11 July 1945, saw the boat leave Subic Bay headed south to the Gulf of Siam, one of the few areas that still had enemy shipping traffic, albeit of the shallow draft kind.

Arriving in the patrol zone, by 2 August, she fought her first surface action in the region– against two junks– with Kinsella noting in his log, “We now have 3 fathoms of water under us. This is indeed poor employment for as valuable a fighting unit as a U.S. submarine, but this is the way we must get our targets nowadays.”

She continued her rampage against the lilliputian shipping on an epic scale. It was a necessary war, as the craft, under Japanese orders, were carrying salt, fish, rice, and sugar to enemy units, all inside the 10-fathom curve.

Case in point: On the morning of 7 August, while patrolling off Lem Chong Pra, she encountered a coaster and, stopping it by ramming, found the vessel with contraband and sank it via boarding party.

Pursuing another small coaster, which beached itself, Ray spotted seven two-masted cargo junks in a hidden cove as well as masts for another 16 vessels (six 250-ton schooners, a 180-ton schooner, 5 75-ton junks, a 50-ton junk, and three 30-ton junks) further down the anchorage. At 1950, on all four engines running on the surface and all deck guns loaded, “With range 2,000 yards and 1 fathom of water under keel, turned right to bring 5-inch gun to bear.” An hour later, after 64 rounds of 5-inch, all 16 of the vessels at the anchorage were sunk or sinking.

To destroy the junks in the hidden cove, just after dusk, a boarding party consisting of a JG and two gunners mates in the sub’s No. 1 rubber boat, loaded with small arms, covered No. 2 rubber boat with the ship’s XO and two torpedo mates with demo gear.

By midnight, all seven junks, floating in just four feet of water, were “burning furiously,” and the away team had been recovered with no casualties, with 40 rounds of 40mm pumped into the illuminated targets for good measure. The sub had destroyed 24 vessels in 24 hours.

On 9 August, having expended almost all of her 5-inch rounds in sinking 35 small craft (totaling 2,915 tons), she was ordered back to Subic Bay.

She covered 12,165 miles in what turned out to be her final war patrol. Ordered stateside with the outbreak of peace, she made Pearl Harbor on 15 September 1945, celebrating VJ Day underway, and left for New London five days later, arriving in Connecticut on 5 October.

She ended the war with an unofficial tally of 75.5 enemy ships sunk (including all the coastal vessels) for a sum of 155,171 claimed tons, later adjusted post-war to a more correct 49,185. She also rescued no less than 23 aviators, laid at least one minefield with unknown results, and conducted two special missions.

USS Ray earned eight Battle Stars across her WWII patrols, along with the Navy Unit Citation and the Philippine Republic Presidential Citation.

Her Jolly Roger, complete with eight battle stars under the submarine insignia, dozens of warships and maru tallies and parachutes for her 13 Naval aviators and 10 Army aircrew rescued

Ray served in a training capacity at New London until 12 February 1947, when she was placed out of commission in reserve.

SSR conversion

The Navy embarked on a series of radar picket conversions to fleet submarines starting just after WWII. This carried across three Project “Migraine” series conversions that saw 10 veteran boats land their guns and torpedoes in exchange for large surface search and height-finding radars.

Of course, this kneecapped the subs for operations as…subs… since they had to lock their radar arrays parallel with the axis of the boat before diving, and they were relegated to 6 knots or less while submerged.

Migraine I: (pre-SCB number) two Tench-class submarines, USS Requin (SS-481) and USS Spinax (SS-489), in which radar panels and electronics took up the space of the rear torpedo room, originally intended to serve in the invasion of Japan in 1946. They still had their forward torpedo room, and the stern tubes could be loaded/reloaded externally and retained their forward deck guns.

Migraine II (SCB 12): belowdecks radar equipment moved to aft battery room, radars moved to masts, and rear torpedo room and two forward torpedo tubes converted to berthing for operators. This limited these boats to just four forward tubes and eight torpedoes. Four subs were converted: Balao-class boat USS Burrfish (SS-312), Tench class USS Tigrone (SS-419), while Spinax and Requin were upgraded. These boats were all redesignated SSR (submarine, radar).

Migraine III (SCB 12A): All six of the boats in this program were “stretched” Manitowoc-built Gatos: USS Pompon (SSR-267), Rasher (SSR-269), Raton (SSR-270), Ray (SSR-271), Redfin (SSR-272), and Rock (SSR-274), with each given a 29-foot hull insert amidships ahead of the main control room to allow a dedicated CIC compartment for the radars. This grew these 312-footers to 341 feet oal and saw the entire sail replaced with an enlarged, more streamlined version. It was also the first SSR conversion to delete all installed deck guns. However, the addition of the CIC “plug” allowed these boats to retain all six of their forward torpedo tubes. They carried a sail-mounted BPS-2 search radar mounted aft of the periscopes, a BPS-3 height finding radar on a pedestal behind the sail, and an AN/URN-3 TACAN beacon on the afterdeck.

The profiles of the three Migraine project generations from the Navy’s ONI 31 sighting guide from 1955:

In December 1950, Ray was towed from mothballs to the Philadelphia Navy Yard for her Migraine III conversion, and she was recommissioned on 13 August 1952.

She was one of ultimately eight SSR/SSRNs in the Atlantic fleet in the 1950s and made two deployments (1 March to 26 May 1954 and 5 March to 4 June 1956) to the Med under 6th Fleet orders, the rest of her short second career was occupied in a series of fleet exercises and type training.

30 April 1954. USS Ray (SSR-271) acting as a radar picket submarine for USS Randolph (CV-15) during operation “Italic Sky One” in the Mediterranean. 80-G-639551

The SSR was made obsolete by the one-two deployment of the new land-based EC-121 Warning Star in 1954 and the carrier-borne E-1 Tracer in 1958, which could operate from even older Essex-class flattops. 

USS Mauna Kea (AE-22) highlines ammunition to the USS Bennington (CVS-20) in the Gulf of Tonkin the 10 September 1968. Our carrier has nine S-2E Trackers, two E-1B Tracer “Stoof with a Roof” models, and at least four SH-3A Sea Kings on deck. This would be Bennington’s final deployment and would end on 9 November. USN 1137061

With the nature of their conversion rendering them less than ideal for retention as traditional fleet subs, the end of the road was reached.

Ray departed Norfolk on 30 June 1958 and entered the Charleston Navy Yard for inactivation. Placed out of commission in reserve on 30 September 1958, she was struck from the Navy list on 1 April 1960, stripped of anything useful to keep her sisters in service, and her hulk was sold for scrap.

Her unconverted sisters lingered on for a few more years as USNR training boats.

The salvage price for most of the WWII fleet subs sold for scrap during this period was about $35,000 per hull, versus a $4.6 million construction cost.

Epilogue

Ray has a detailed marker as part of the Manitowoc “28 Boat Memorial Walk” at USS Cobia.

U.S.S. Ray (SS 271) Marker

She also has her war history, war patrols, and 1950s deck logs in the National Archives.

As for her two wartime skippers, plank owner Brooks Harral was a submarine division and squadron commander in Panama, Key West, and San Diego before returning to Annapolis, where he served as head of English, history, and government until 1957. Retiring as a rear admiral in 1959, he later penned “Service Etiquette” for all military academies.

He passed in 1999 and is buried in the Naval Academy Cemetery.

Ray’s second wartime skipper, Bill Kinsella, also retired from the Navy as a rear admiral after a stint teaching at the Naval Academy. During his time on SS-271, he earned two Navy Crosses and the Legion of Merit. He passed in 2003 at age 89.

In the early 1980s, he wrote a pamphlet about the boat, “The History of a Fighting Ship U.S.S. RAY (SS271)” by Rear Admiral William T. Kinsella, USN (Ret.), which is long since out of publication.

The Navy soon recycled Ray’s fine name for a Sturgeon-class submarine (SSN-653) commissioned in 1967. Notably, she was the first of her class to become Tomahawk certified in 1985, capable of shooting both TLAM and TLAM-N cruise missiles through her torpedo tubes, a game changer for SSN ops.

This latter Ray earned five Navy Unit Commendations, six Meritorious Unit Commendations, six Navy Expeditionary Medals, and at least three Arctic Service ribbons across her 26-year career.

Warship Wednesday, April 23, 2025: The Seas are Alive…with the sound of Torpedoes

Above we see le croiseur cuirasse Leon Gambetta.

She was a beautifully obsolete ship that intersected history in several unusual ways and was lost to an infamous Austrian submarine skipper some 110 years ago this week.

French armored cruiser Amore

The French invented the concept of the true armored cruiser when Dupuy de Lome was ordered in 1888. A 6,300-ton steel-clad iron-hulled steamer, Dupuy de Lome could make 20 knots on her 11 Amirauté fire-tube boilers and three engines and had no auxiliary sail scheme.

The French armored cruiser Dupuy de Lome

Swathed in as much as 5 inches of plate armor, she carried eight large (7.6 and 6.4-inch guns) as well as 18 smaller pieces (37mm, 47mm, and 65mm) while also carrying four small (17.7-inch) torpedo tubes.

Able to operate alone and far from home if needed (Dupuy de Lome could steam at 12.5 knots for 4,000 nm), she was capable of defeating anything smaller than a genuine battleship, which she could outrun.

The concept ship was followed by the four-ship Amiral Charner class, the one-off cruisers Pothuau and Jeanne d’Arc, the trio of Gueydon-class cruisers, the three ships of the Dupleix class, and the five-unit Gloire-class. In all, in the 13 years between 1888 and 1901, the French had ordered 18 armored cruisers, with each class learning from the preceding one.

The result, the Gloire and her sisters, ran 9,996 tons, had an amazing 28 boilers (!) to drive three engines to obtain a 21-knot speed, and could steam 6,500 miles ecumenically. They carried 10 large guns (2x 7.64″/40, 8x 6.5″/45) as well as six 3.9″/50s, 18 x 45mm guns, and 4 x 37mm guns, plus five 17.7-inch torpedo tubes. All of this was protected by as much as 6.9 inches of armor.

Gloire-class armored cruiser Conde is pictured at Arsenal de Brest, c1918. A true floating castle with four funnels and a curious mix of armor and armament.

The three follow-on Gambetta class armored cruisers (class leader Leon Gambetta and Jules Ferry, followed by half-sister Victor Hugo) were up-sized Gloires, displacing 11,959 tons on a hull some 30 feet longer (489 feet vs 458 feet) and four feet beamier.

All three ships used different boiler arrangements (Gambetta 28 Niclausse boilers, Ferry 20 Guyot du Temple boilers, and Hugo 28 Belleville boilers) with triple engines that produced roughly 28,500 shp to make about 22 knots and steam 6,600nm at 10 knots.

Armament on the Gambettas was a repeat of the Gloires, albeit with two fewer 6.5-inch guns and a third more 47mm mounts (24 up from 18). Likewise, they only had two torpedo tubes. The armor plan was also similar to that of the Gloire.

To speed things up, the trio was laid down at three different naval yards, with Gambetta constructed at Brest, Ferry at Cherbourg, and Hugo at Lorient, with all constructed between January 1901 and April 1907.

A heavier update to the class with more guns and armor, the 13,000-ton Jules Michelet, was constructed soon after joining the fleet in 1908.

Naval architect Emile Bertin kept tinkering with the Gambetta design to produce the 13,644-ton cruiser Ernest Renan in 1909 and her half-sisters Edgar Quinet and Waldeck-Rousseau, which were the most powerful (and last) armored cruisers built in France, commissioned in 1911.

But we are getting ahead of ourselves.

Meet Gambetta

Our subject is the first French warship named after the 1870s political and cultural juggernaut, Leon Gambetta, who was key to the formation of the Third Republic and served at various times as the country’s minister of the interior, Président du Conseil, and Président de la Chambre des deputes before his young death at age 44 in 1882. Something like 200 towns have a Rue Gambetta in France to this day, and his likeness remains borne in numerous statues throughout the Republic.

Odds are, if you have been to France in the past 140 years, you have either walked upon a street named for Leon Gambetta or gazed on his face. He is right up there with Leclerc, Ferry, Foch, and Clemenceau.

The armored cruiser ordered in his honor was laid down at Arsenal de Brest on 15 January 1901.

She was launched into the waters of the Bay of Biscay on 26 October 1902.

While on sea trials in February 1904, she ran aground in the fog and required dry docking for another six months, then promptly ran aground a second time, sending her back to the yard for further repair.

Gambetta, Brassey’s Naval Annual 1905

She finally finished her trials and was accepted and commissioned on 21 July 1905, with her cumulative construction cost hitting 29,248,500 francs.

Made the flagship of VADM Camille Gigon’s (later VADM Horace Jaureguiberry’s) 1re Division de croiseur as part of the Northern Squadron, she immediately sailed to Portsmouth in August 1905 for the Anglo-French naval review to celebrate the historic Entente Cordiale, which ended centuries of tension between London and Paris and helped set the stage for the Great War.

The French ships were reviewed by King Edward VII and hosted in a variety of events ashore for the Gallic visitors throughout the week, including a garden party in Victoria Park.

Remaining a ship of state, she carried President Clement Armand Fallieres to England in May 1908 for an official visit and, later that summer, represented France at the Quebec Tercentenary.

By 1911, the three Gambetta sisters would make up the 1re Division legere in the French Mediterranean fleet with RADM Louis Dartige du Fournet hoisting his flag on our subject.

War!

Carrying the flag of RADM Victor-Baptistin Senes, Gambetta entered the Great War at the head of the 2e Division legere out of Toulon and was soon busy escorting troopships moving colonial troops from French North Africa to the Republic proper.

Then came orders to join the force of ADM Augustin Boue de Lapeyrere’s fleet of two dozen battlewagons and cruisers blockading the Austro-Hungarian coast along the Adriatic. This included several sharp skirmishes with Austrian ships, tracking the neutral Italians, supporting the Serbian and Montenegrin armies ashore, and escorting troop ships through U-boat-infested waters.

Speaking of the latter, on 26 April 1915, she was found at sea by SM U-5 of the k.u.k. Kriegsmarine. A humble 105-foot gasoline-electric submarine designed by Electric Boat of Connecticut to the same plans as used by the U.S. Navy’s C-class, U-5 only carried four 17.7-inch Whitehead torpedoes to be fired from her two forward tubes.

Kuk S.M. U 5 

The tiny boat, good only for 10 knots under the best sea conditions, her new skipper, Linienschiffsleutnant Georg Ludwig Ritter von Trapp, had only assumed command nine days prior. Von Trapp, from a noble family and husband to Agathe Whitehead, granddaughter of the torpedo godfather, had joined the Austrian fleet at age 14 in 1894 and had served in China during the Boxer Rebellion with the surface fleet before switching to submarines in 1908.

Von Trapp, in his tiny a risky little boat, continued to stalk Gambetta in the Ionian Sea off Italy’s Cape Santa Maria di Leuca into the night and, closing to within 500 yards, fired both tubes at point blank range just after midnight on 27 April.

With hits against the massive target inevitable, both fish exploded and created havoc on Gambetta, which soon began settling in the water, her boilers knocked out. Ten minutes later, it was all over, and the proud cruiser was on the bottom, taking every single one of her officers and the bulk of her 800-man crew with her.

Escorted by Italian destroyers who had only entered the war that week, they rescued 137 waterlogged survivors from the lost French cruisers.

Von Trapp made history that pre-dawn morning, conducting the first-ever underwater nighttime (and only the second) submarine attack on a vessel in the region. Gambetta remained one of the largest ships hit by a U-boat during the war.

For the feat, he would eventually earn the coveted Militär-Maria-Theresien-Orden, the highest military honor of the old Habsburg monarchy, and he would become a household name in both Austria and Germany.

Propagandists on both sides took advantage of the loss to show how brave French sailors met Poseidon without fear and how, for the Central Powers, the U-boat was a modern marvel of war, commanded by a brave modern-day knight of the sea

As for Von Trapp, just three months after sending Gambetta to the bottom, he sank the Italian submarine Nereide on 5 August 1915, just off Pelagosa (Palagruza) Island. He followed that up with capturing the Greek steamer Cefalonia three weeks later. Before the end of the war, Von Trapp would add 11 more steamers to his tally sheet, surviving 19 war patrols.

Epilogue

Little remains of Gambetta topside that I can find.

Her sisters, Jules Ferry and Victor Hugo, survived the war and, after overseas service policing French colonies in the Far East, were retired and scrapped in the late 1920s.

Von Trapp, left without either a navy or a sovereign when Austrian Emperor Karl left the throne in November 1918, had to fall back on his personal inherited fortune. Left a widower with seven children in 1922 upon the passing of his wife due to scarlet fever, he hired one Maria Augusta Kutschera, a young novice from the nearby nunnery, as a live-in tutor, and the old sea dog later married her in 1927 despite the 25-year age difference, and had three further children.

The Von Trapp family then drifted into a singing career, and the rest is history.

Von Trapp, exiled from Austria in 1938, later settled in the U.S., where he passed in 1947, aged 67. He is buried in Stowe, Vermont.

Christopher Plummer portrayed him in the 1965 movie, The Sound of Music, which was very loosely based on the family’s story in the 1920s and 30s.

Iowa, Arriving

The fourth U.S. Navy vessel named for the state of Iowa, the future USS Iowa (SSN-797), was delivered to the Navy on 22 December 2024 and, as the Hawkeye State is slim on blue water ports, was commissioned at her homeport of Groton over the weekend.

The last Iowa, the famed class-leading fast battleship BB-61, which was christened on 27 August 1942, was only stricken from the NVR on 17 March 2006 and endures as a floating museum at Los Angeles, the only West Coast battlewagon.

SSN-797 is the 24th Virginia class hunter killer delivered since 2004 and is the sixth advanced Block IV variant, which includes the big new LAB sonar array and 12 VLS cells.

She will join Submarine Squadron (SUBRON) 4 at Groton, which will include the USS Virginia (SSN 774), the USS South Dakota (SSN 790), the USS Hyman G Rickover (SSN 795), and the future PCU Idaho (SSN 799) and PCU Tang (SSN 805).

Warship Wednesday, April 2, 2025: Jeezy Breezy, We Hit Em!

Naval History and Heritage Command photo NH 90825

Above, we see the Balao-class fleet boat USS Charr (SS-328), off Mare Island Naval Shipyard, Mare Island, California, 16 September 1946, just after the war.

Although she got into the war late, only starting her first war patrol in December 1944, Charr has the distinction of sinking the last enemy cruiser sent to the bottom by a U.S. submarine, a feat accomplished after a four-day chase some 80 years ago this week.

The Balao Class

A member of the 180+-ship Balao class, she was one of the most mature U.S. Navy diesel designs of the World War Two era, constructed with knowledge gained from the earlier Gato class. Unlike those of many navies of the day, U.S. subs were “fleet” boats, capable of unsupported operations in deep water far from home. The Balao class was deeper diving (400 ft. test depth) than the Gato class (300 feet) due to the use of high-yield strength steel in the pressure hull.

Able to range 11,000 nautical miles on their reliable diesel engines, they could undertake 75-day patrols that could span the immensity of the Pacific. Carrying 24 (often unreliable) Mk14 Torpedoes, these subs often sank anything short of a 5,000-ton Maru or warship by surfacing and using their deck guns. They also served as the firetrucks of the fleet, rescuing downed naval aviators from right under the noses of Japanese warships.

Some 311 feet long overall, they were all-welded construction to facilitate rapid building. Best yet, they could be made for the bargain price of about $7 million in 1944 dollars (just $100 million when adjusted for today’s inflation) and completed from keel laying to commissioning in about nine months.

An amazing 121 Balaos were completed through five yards at the same time, with the following pennant numbers completed by each:

  • Cramp: SS-292, 293, 295-303, 425, 426 (12 boats)
  • Electric Boat: 308-313, 315, 317-331, 332-352 (42)
  • Manitowoc on the Great Lakes: 362-368, 370, 372-378 (15)
  • Mare Island on the West Coast: 304, 305, 307, 411-416 (9)
  • Portsmouth Navy Yard: 285-288, 291, 381-410, 417-424 (43)

We have covered a number of this class before, such as the sub-killing USS Greenfish, the UDT-10 carrying USS Burrfish, the rocket mail slinger USS Barbero, the carrier-slaying USS Archerfish, the long-serving USS Catfish, the U-boat scuttling USS Atule, Spain’s “30-one-and-only,” and the frogman Cadillac USS Perch —but don’t complain, they have lots of great stories

Meet Charr

Originally to be the first warship named after the Bocaccio, a type of West Coast rock fish, our subject was laid down, 26 August 1943, at Electric Boat in Groton. The powers that be swapped this tough to spell marine creature for the much easier Charr, a type of trout common to the Pacific Northwest, a month later.

As such, the future USS Charr- the only warship to carry the name-  was launched on 28 May 1944, sponsored by the wife of a no doubt upstanding citizen of Groton, and commissioned on 23 September 1944, her construction spanning a scant 394 days. At the time, EB was building them so fast that it was a dual commissioning ceremony– the first at New London- with sistership USS Boarfish (SS-327), who had been laid down just a fortnight before Charr.

Charr’s plank owner skipper was CDR Francis Dennis Boyle (USNA ’34). It was his first command, having gone out as a junior officer and XO on three previous war patrols on other fleet boats.

Sailing for the West Pac on 5 November to join the Big Show after six weeks of shakedowns, she arrived at Pearl Harbor via the Ditch in early December and spent Christmas of 1944 at Pearl Harbor.

She had a fairly green crew, with her wardroom averaging out to about two patrols per officer (although her two most junior ensigns were mustangs with 14 patrols between them). Meanwhile, her goat locker had a similar average with three of her chiefs counting zero patrols between them. Overall, only 43 of her 80 men aboard had earned their dolphins.

War!

On 30 December 1944, Charr was escorted out of Pearl Harbor along with the veteran boat, USS Batfish, to begin her first war patrol, ordered to roam the South China Sea by way of Saipan. Clearing that occupied former Japanese possession on 13 January 1945 with a full load of diesel oil and provisions topped off from the sub-tender USS Fulton, Charr made for her patrol area and spent the next several weeks fighting heavy seas while hiding from Japanese patrol aircraft.

She dodged a couple of floating mines and made a rendezvous at sea with her commissioning mate Boarfish on 27 January off Pulo Kambir, some 8,500 miles away from New London. Small world!

The next day, she was dispatched to close with the coast of Japanese-occupied French Indochina to search for downed fliers. Anchoring just 2,700 yards offshore, a landing team recovered the radioman of a downed aircraft in broad daylight on the 29th, then had to return after dark for the rest of the aircrew but found herself in the middle of Japanese convoy HI-88-B (Singapore to Moji).

From Charr’s patrol report:

While Boarfish was lucky enough to sink the Japanese tanker Enki Maru (6968 GRT) and force the tanker Daietsu Maru (6890 GRT) aground, Charr came away from the encounter empty-handed, never able to get close enough to make an attack. Transferring her navy radioman aboard her sistership, which was Fremantle-bound, Charr remained on fruitless patrol, working off and on with the fellow fleet boats USS Tuna and Blackfin.

On 21 February, while Boarfish’s crew was enjoying the bars and beaches of Western Australia, Charr crossed the equator and was ordered to go to the rescue of the imperiled Dutch T-class submarine HrMs Zwaardvisch (P 322), which she did on the 22nd. She would spend the next four days on a risky southbound passage to Lombok Strait on the surface.

Charr ended her 1st patrol at Fremantle on 3 March, having not fired any torpedoes, dodged over 20 enemy air contacts, and only fired her guns (20mm) at enemy mines. Despite the risky rescue of the downed Navy radioman, and boldly escorting Zwaardvisch back to safety, the patrol was not deemed by COMSUBPAC to be successful.

On the bright side, she ran 13,799 miles across 63 days on her first patrol with no casualties, and 75 of 80 men aboard had dolphins at the end of it. She was ready.

Second Patrol

Charr sailed out of Freemantle again on 27 March after refit, ordered, in part, to comb the Flores, Java, and South China Seas in coordination with USS Gabilan (SS-252) and Besugo (SS-321) while HM Submarine Spark was nearby but not attached. Charr celebrated Easter submerged on 1 April entering the Lombok Strait.

Soon, this Yankee wolfpack would sniff out one of the Empire’s last operational cruisers outside of Japan’s home waters.

The Nagara class light cruiser Isuzu had helped seize Hong Kong from the British and survived the Solomons and the hellfire of the Leyte Gulf, but her days had run out.

Tasked with collecting isolated Japanese troops from Kupang and taking them to Sumbawa Island with an escort of a torpedo boat and two minesweepers, Boyle’s wolfpack (he was SOPA) sighted the little convoy off Paternoster Island at 1125 on 4 April but were forced to submerge due to Japanese air cover. Meanwhile, Gabilan sank a small Japanese vessel with gunfire in a surface action.

Besugo got close enough in the predawn of 5 April to fire six torpedoes at Isuzu and one, throat down, at her escorts, all of which missed.

The pursuit continued with RAAF Mosquitos of No. 87 Squadron and FRUMEL intercepts, pointing the way for B-25s of the Free Dutch No. 18 Squadron to attack the force on the morning of 6 April, dropping 60 500-pound bombs without result.

Meanwhile, Isuzu picked up her assigned marooned troops and deposited them that afternoon at Sumbawa, unharmed. A second attack by B-24s of the RAAF’s Nos. 21 and 24 Squadrons later that day left Isuzu limping and on manual steering.

It was in the afternoon of 6th April, between Sumbawa and Komodo islands is the Sape Strait, that Boyle’s wolfpack caught up to the Isuzu group again. Besugo fired another 11 torpedoes in two attacks and bagged the escorting Japanese minesweeper W 12 (630 tons) for her effort, then was forced back to Freemantle as she was out of fish. She surfaced and saw survivors in the water after the Japanese had moved on “but all refused to be picked up.”

At 0255 on 7 April, Charr made radar contact with Isuzu and her two remaining escorts at 14,700 yards, making their way out of Sumbawa’s Bima Bay. “Bingo, this may be the jackpot,” noted Boyle.

Radioing the contact to Gabilan, who was in the path of the Isuzu group, that submarine made an attack on the cruiser with five torpedoes, one of which hit below the bridge, causing flooding forward and cutting her speed to 10 knots.

Meanwhile, Charr moved in for the kill. From her patrol report:

Isuzu was the last of her class in Japanese service remaining and the final Axis cruiser sunk by an American submarine.

The next day, the wolfpack broke up, with Gabilan and Spark heading on their ways as Charr was detailed to complete a Special Mission (planting a minefield off Pulo Island) while sinking a 500-ton Japanese coaster on 10 April via gunfire. On the 13th, they received word of FDR’s death (“All hands are deeply saddened”), then on the 16th fired six torpedoes at two Japanese escorts in the Gulf of Siam without luck.

Stopping in at Subic Bay briefly on 20-24 April, she then headed to Formosa for lifeguard duty, saving USAAF Lt. Hugo Casciola, a Fifth Air Force P-51 pilot (likely of the 3rd Air Commando Group), on 6 May.

Ending her 56-day patrol at Subic on 21 May, Charr sailed 11,688 miles. Her patrol was deemed a success and a Submarine Combat Insignia was authorized, with Charr credited for 5,670 tons of Japanese shipping sunk.

Third Patrol

On 14 June 1945, Charr left Subic Bay for her 3rd war patrol, ordered to the Gulf of Siam, one of the few areas with a significant Japanese presence afloat, even if it was in the form of coastal traffic. By the end of the month, she formed an Allied wolfpack with HMS Selene (P 254) and Sea Scout (P 253), later joined by Supreme (P 252). They chased down a small Japanese convoy not worth the torpedoes to sink but could never get close enough to engage it with gunfire.

On 5 July at 0042 while on the surface alone, Charr’s lookouts spotted an incoming torpedo that only missed them by 25 yards, with Boyle noting “Evidence of the torpedo from its wake is unmistakable” as Charr left the area at flank speed.

With the three luckless British S-boats returning to Freemantle, Boyle, on 11 Jul,y inherited an all-American pack built around USS Hammerhead, Blower, and Bluefish. Four days later, Bluefish, birddogged by reports from Blower, who fired four torpedoes at a Japanese I-class submarine contact, found I-351 on the surface 100 miles out of Natuna Besar, Borneo with a cargo of 42 irreplaceable naval aircrewmen. Bluefish sent I-351 and 110 of her 113 crew and passengers to the bottom with a four-torpedo spread.

Charr ended her 43-day 3rd war patrol at Fremantle on 26 July. Although her group bagged a big Japanese sub, that was Bluefish’s kill, and, thus, the patrol was not deemed worthy of an SCI.

As WWII ended before Charr could begin a fourth patrol, she ended the conflict with just one battle star for her second patrol. She was then dispatched to Guam to join SUBRON5.

Charr then returned to the West Coast on 27 January 1946, capping 15 months deployed out of CONUS. A refit at Mare Island and a new skipper followed.

Cold War Snorkel Days

With the Navy rapidly demobilizing, there still had to be somebody on watch, especially with conflict boiling around the suddenly post-colonial West Pac, and Charr was one of several subs tasked with making what were termed simulated war patrols. One 115-day training patrol, departing San Francisco on the 4 October 1946, included visits to Pearl, Subic Bay, Shanghai, and Tsingtao China, as well as Yokosuka Japan, and was concluded at San Diego on 27 January 1947. A second one followed soon after.

She then fell into a quiet peacetime period of drilling naval reservists on two-week coastal deployments along the California and Mexican coasts with two dozen reservists aboard, serving as a training boat to the Submarine Training Facilities San Diego, participating in exercises, and earning a series of Battle Es including the Marjorie Sterrett Battleship Fund Prize in 1948, the first for a Pacific sub.

On 10 July 1951, she entered Mare Island to be converted to a “Four-engine Fleet-type Snorkel” submarine, emerging four months later with a radically different topside appearance.

Besides the obvious snorkel installation and sensor updates, the conversion gave her a new streamlined sail and removed her deck guns. She also sported a two-tone scheme.

Then came the Korean War, which included a six-month war patrol (26 March -2 October 1952) in the region under the orders of Commander Naval Forces, Far East.

Sent to the West Pac again after the cease fire, she left San Diego on 13 June 1954.

USS Charr at speed

She visited Formosa, Taiwan, and met the 7th Fleet boss and the inaugural commander of the U.S. Taiwan Defense Command, VADM Alfred M. Pride, who appeared on hand with exiled Generallisimo Chiang Kei-Shek himself. The 67-year-old first president of the Republic of China toured Charr extensively and got underway briefly on 9 November. Most Americans forget today, but the U.S. had upwards of 20,000 troops deployed at any given time to Taiwan through 1979, when the USTDC was disbanded under the Carter administration.

Then followed a decade of West Coast operations, ranging from Vancouver to Acapulco with naval reservists and participating in public events such as the Seattle Sea Fair and supporting Girl Scout Marine Ship 36 of Pasadena with tiger cruises.

She was in 12,000 feet of water off San Diego on 26 September 1961 when, while rigged for deep submergence, a main motor circulating water hose ruptured at 150 feet, flooding the Maneuvering Room, a situation saved after two ratings sealed themselves in the engine room and maintained power to rapidly bring the Charr to the surface. Living to fight another day, she was towed to San Francisco Naval Shipyard for repairs. John McGee, EM1, received the Navy Commendation Medal, while Douglass Webster, EM3, received a Letter of Commendation for their efforts to save their ship that day.

Operationally, she drilled in PACTRAEX and completed active West Pac deployments with Seventh Fleet in 1957, 1959, 1961, and 1963.

With U.S. involvement in Vietnam ramping up in 1965, Charr was deployed to those waters as a sideshow to SEATO Exercise Sea Horse and, along with a half-dozen other diesel boats, would soon be laying off the North Vietnam littoral on secret observation and lifeguard missions for Rolling Thunder air strikes.

It was during these support operations that Charr recovered CDR Jack H. Harris, commanding officer of VA-155, from the Gulf of Tonkin on 29 March.

Harris, flying from the USS Coral Sea, had ejected from his damaged A-4E Skyhawk (BuNo 150078) after an Alpha strike against North Vietnamese air search radar facilities on Bach Long Vi Island, which is located about 70 miles offshore roughly midway between Haiphong and the Chinese island of Hainan. He was the last pilot to be rescued CSAR style by a lifeguard submarine, almost 20 years to the date from Charr’s WWII lifeguard service. The waterlogged pilot remained on Charr for several days and was eventually high-lined to a destroyer for return to Coral Sea. Sadly, he died in the fire on Oriskany in 1966.

Charr almost got a second rescue from Coral Sea off Bach Long Vi Island as well.

As noted by EM3(SS) Sid Anderson of the old USS Charr Association:

CDR William N. Donnelly, CO of Fighter Squadron 154, flying F-8D BuNo 148642, had his controls shot out while in a dive-bombing run against an AAA site. He ejected while inverted at 450 knots and 1,000 feet altitude, landing about 4 miles from the island. On the night of March 30th, upon becoming aware that transmissions from CDR Donnelly’s emergency radio were being received, the USS Charr surfaced and conducted a grid search but was unsuccessful in finding him. Later that day, during the mid-watch (12 noon to 4 p.m.) CDR Donnelly was sighted floating in his survival raft by aircraft that were en route to another bombing raid. His location was about 14 miles from the Charr, which was submerged at the time. Once in receipt of this information, LCDR John M. Draddy, CO of the Charr, surfaced and proceeded to CDR Donnelly’s location. Upon arrival at the site, a fleet of Chinese junks were already there, with no sight of CDR Donnelly or his raft. With the belief that the junks had gotten to him first, LCDR Draddy quickly assembled an armed boarding party intending to rescue him. However, before any action was taken, LCDR Draddy received word that CDR Donnelly had already been picked up by a U.S. Air Force HU-16 amphibian, and the boarding party was dismissed. In his raft, CDR Donnelly had successfully evaded North Vietnamese patrol boats for some 45 hours.

Entering the twilight of her career, Charr would be redesignated an Auxiliary Submarine (SGSS) in July 1966, and make her seventh West Pac deployment from May to December 1967 that included SEATO Exercise Sea Dog and service as a “tame” Military Assistance Program submarine on loan to the navies of the Philippines, South Korea and China for use in ASW training.

She made her 7,000th dive on 20 July 1968. Not bad work considering most of her constructors were war-hires and “Rosies.”

Spending the rest of her career stateside, Charr was decommissioned on 28 June 1969 in a mass five-way ceremony with the old fleet boats Bream, Tunny, Bluegill, and Raton.

Charr continued “In Service, In Reserve” for another 18 months until 20 December 1971, at which time she was struck from the Navy List. She was sold to Nicolai Joffe, Beverly Hills, for $105,381 on 17 August 1972, then subsequently scrapped in Kearny. New Jersey

Charr earned an Armed Forces Expeditionary Medal for her Vietnam cruise, added to two for Korea, and her sole WWII battle star.

Epilogue

Little remains of Charr.

Her Cold War deck logs, WWII patrol reports, and war history are digitized in the National Archives. 

She had an active veteran’s group that was online until about 2020.

Post-WWII, Charr’s only wartime skipper CDR Boyle, who earned a Navy Cross for sinking Isuzu, did a stint at JPL then got heavily into guided missile research, rising to head White Sands in the late 1950s. He earned his surface warfare badge as commander of the USS Springfield (CLG-7) just after her conversion to a guided missile cruiser and then later broke his flag over Cruiser Destroyer Flotilla 7 as a rear admiral. He retired in 1968 and passed a decade later at age 68. His papers are in the Hoover Institution.

RADM Doyle, Charr’s WWII skipper

Her Vietnam-era skipper, LCDR John Draddy, the man who was ready to fight off a fleet of Chinese junks on the surface with Tommy guns and M1 Carbines to save a downed naval aviator, earned a Bronze Star for that cruise. He retired from the Navy as a captain, 29 years a submariner. He passed in 2005, aged 76, with a host of grandkids, and is buried at Arlington.

The P-51 pilot that Charr plucked from the drink off Formosa in May 1945, Hugo Casciola, survived the war and passed in Pennsylvania in 1976 at age 60. During WWII, U.S. submarines rescued no less than 504 downed airmen from all services.

It would be almost two decades after Chiang Kai-shek rode on Charr that the Republic of China obtained its first submarines, receiving the Balao-class ex-USS Tusk (SS-426) and Tench-class ex-USS Cutlass (SS-478) in 1973, recommissioning them as the “unarmed” training boats Hai Po and Hai Shih respectively. They were later augmented by a pair of Dutch-built SSKs.

Taiwan’s first Indigenous Defense Submarine (IDS), Hai Kun (SS-711), was launched last February at the CSBC shipyard in Kaohsiung. She is set to wrap up sea trials this month.

Above we see the USS F-4 (Submarine No. 23) along with her three sisters, USS F-2 (SS-21), USS F-3 (SS-22), and USS F-1 (SS-20), proud and flying their “fish” flags and 13-star “boat” ensigns with their crackerjacks waiting either for a division inspection or shore leave– or both.

Taken in Pearl Harbor in 1914, these early boats were the first based in Hawaii, predating the construction of the submarine base, and as such were simply docked at Pier 5 at the end of Richards Street in Honolulu near where the Aloha Tower is today.

Less than a year later, on 25 March 1915– some 110 years ago this week– F-4 would take her final dive and a lot of those brave young men on her deck would vanish.

The F-class boats

The story of early American submarines was one of John Philip Holland’s Torpedo Boat Company which became the Electric Boat company in 1899.

Holland and his company would provide the Navy’s first steel boat, the 53-foot USS Holland (Submarine Torpedo Boat #1) in 1900, followed by the seven 63-foot USS Plunger (SS-2) or A-class boats, and three 82-foot B-class boats– all very small, basically midget submarines. EB’s five follow-on C-class boats, designed by Lawrence York Spear after Holland’s death, were steadily larger, at 105 feet, and used twin engines and twin motors, giving them a measure of reliability. Nonetheless, all these early boats, and those that immediately followed, were known as “pig boats” due to their downright foul living quarters and unusual and downright unship-like hull shapes, which tended to wallow and hog on the surface.

Then, as now, the U.S. Submarine arm is all-volunteer.

Spear’s D-class boats– the first American boats to run four torpedo tubes, were subcontracted out to Fore River and were the largest yet, at 134 feet. Spindle shaped and single-hulled with short sails, they would become the basis for Navy sub hull forms for the next decade.

The two left are probably (in no order) USS E-1 (Submarine # 24) and USS E-2 (Submarine # 25). Courtesy of Commander Donald J. Robinson, USN (Medical Service Corps), 1973. NH 78926

By 1909, less than a decade after the first Holland boat was bought by the Navy, Fore River began construction of a more modern pair of boats, dubbed the E-class, that were roughly the same size as the D-class that preceded them but, importantly, ditched the dangerous gasoline engines of the previous designs for a pair of NELSECO diesels. Importantly for maneuverability while diving, they were also the first U.S. submarines to have bow planes.

Further, they incorporated both a search and attack periscope along with a narrow-windowed conning tower, complete with deadlights.

This gives us the F-class, which are just improved Es, and were only the second group of American designed and built diesel-electric submarines.

F-class boats were the first U.S. Navy submarines built on the West Coast, with the first two, F-1 and F-2, constructed by Union Iron Works in San Francisco as Yard No. 94 and 95 using NELSECO diesels. The second pair, F-3 and F-4, were the first subs launched into Puget Sound, built as Yard No. 55 and 56 by The Moran Company, which soon after became Seattle Construction and Drydock Co. The latter pair used Craig diesels.

The D, E, and F classes were the first American submarines (and some of the first anywhere) to have permanently installed radios, and the latter class used telescoping aerials as well.

An improved version of the E-class subs, Fore River provided the design sheets to Union and Moran, which each respective company used in building their first submarines.

General plans prepared by the Fore River Shipbuilding Company, Quincy, Massachusetts, 18 June 1910. This sheet features inboard and outboard profile drawings. These submarines were constructed by the Union Iron Works, San Francisco, California. Initially named Carp (Submarine # 20), Barracuda (Submarine # 21), Pickerel (Submarine # 22), and Skate (Submarine # 23), they were renamed F-1 through F-4 in November 1911 while under construction. NH 84383

Same as the above. Note the three divided sections, fore, middle, and stern. NH 84382

Running some 142 feet overall and able to float on the surface in just 12 feet of water, the F-class were still designed more for coastal and harbor defense than blue water patrols. Just 330 tons when surfaced, they used two small 390 hp NELSECO or Craig diesels to make 13.5 knots on trials. Submerged, at 400 tons, they used a pair of 120 kW Electro Dynamic electric motors fed by two 60-cell steel-jar batteries to make 11.5 knots, a speed they could only maintain for about an hour or so before the batteries were drained.

Overall, they were designed for patrols lasting no more than a week and only carried 33 tons of diesel oil- enough to allow for a 2,300nm range at 11 knots.

Constructed of mild steel, riveted in place and depermed, they had a test dept of 200 feet and could submerge in just 45 feet– although the aerials would still betray them. While on trials in 1913, F-1 dived to 283 feet in tests, but after her hull groaned and she started taking on water within ten minutes, she quickly made it to the surface.

Armament was a four-pack of 18-inch torpedo tubes in the bow behind a rotating torpedo tube muzzle cap– a main battery pioneered just a few years earlier in the D-class– with one set of reloads, allowing for eight fish maximum if all spots were filled. There was no provision for a deck gun and the fairwater or conning tower was short and thin, prone to spray and wash while underway.

The F-class were, to be blunt, just an evolutionary step for the Navy, who soon after would order larger and more sophisticated G, H, K, L, and M-class boats– all before entering the Great War, accumulating 51 commissioned submarines by 1917.

Meet F-4

Laid down on 21 August 1909 at Moran as the future USS Skate (Submarine No. 23)– the first American warship to carry that later storied name- our subject was renamed a more generic USS F-4 on 17 November 1911. Launched on 6 January 1912, sponsored by the wife of a shipyard executive, she was commissioned 3on  May 1913.

F-4. Note the tiny conning tower with the trunk between the two periscopes. It was thought the conning tower was the most likely part of the boat to be struck during a collision while submerged or carried away by a wave on the surface, so it was made as a separate watertight compartment that could, at least in theory, be wrenched off without breaking the integrity of the hull, provided the hatch was dogged tight. However, it was so small that it could not be used for much, and the skipper and XO had their duty stations, even in an attack run, standing by the diving controls and steering stations.

The four F-boats were assigned to the First Submarine Group, Pacific Torpedo Flotilla, based at San Pedro and operated on the West Coast as such until August 1914.

Tender USS Alert and four F boats, San Diego, 1914. Alert, an iron-hulled steam sloop that entered the fleet in 1875, had been decommissioned in 1907 and lent to the California Naval Militia. The Navy recalled her in 1912 specifically for use as a submarine tender for the F-class. 

Then, with war in Europe and a German cruiser squadron roaming the Pacific pursued by British and Japanese fleets, our little F-boats were towed to Hawaii behind armored cruisers to provide presence in the islands.

The Final Dive

The early days of submarining were highlighted by the tendency for these submersibles to claim the lives of their crews. After all, the infamous Hunley sank three times during her seven-month career, on each occasion with a total loss of her complement.

The U.S. Navy was lucky for a time, while European powers and Japan suffered no less than 21 fatal submarine losses between 1903 and 1914, claiming over 200 lives. That luck ran out on the morning of 25 March 1915 when an accident occurred on F-4 while she was off Oahu on maneuvers, sinking to the sea floor 306 feet below with two officers and 19 enlisted aboard.

She had left her tender, the old gunboat USS Alert, at 0900 for a submerged run at a maximum depth of 30 fathoms (180 feet) for target runs but failed to return to the surface by noon. While her emergency buoy was not seen, a sheen of diesel oil appeared on the surface some 1.5 miles off Fort Armstrong between Diamond Head and Barber’s Point, about a mile and a quarter from the channel entrance.

As described by the Submarine Force Museum:

When the F-4 was at a depth of something less than 60 feet, chlorine gas began seeping into the middle, or control, compartment of the boat, indicating that somehow salt water had reached the batteries. F-4’s commanding officer, LT(JG) Alfred Ede, ordered the boat to return to the surface but soon the engines, straining to lift the weight of the sub plus tons of added seawater from what was obviously a substantial leak, overheated and quit. Before the Sailors in the control section retreated to the engine room—several already having passed out after breathing too much of the chlorine gas—they tripped the system that blew air from the high-pressure tank into the main ballast tanks.

But it was too late; water was pouring into the boat faster than the air could blow it out and soon the F-4 came to rest on the bottom, 300 feet below the surface, about 100 feet greater than her test depth. The pressure of the surrounding water soon overcame the rivets that held the torpedo hatch in place and the two forward compartments flooded quickly. Although the crew had secured the hatch behind them when they moved back to the engine room, the bulkhead around it couldn’t hold out against the weight of water and collapsed.

Rescue…turns to recovery

For two days, the Navy combed the waters near where F-4 had been lost and, using drags followed up by divers, was able to approximate her position on the sea bottom. Two Navy hard hat salvage divers attached from the submarine flotilla, GMCs John “Jack” Agraz and John Evans, descended rapidly to 190 feet without seeing the sub. Agraz attempted again and made it to 215 feet- a record at the time for open ocean work- in an unsuccessful attempt to reach the bubbling sub.

A hairy-chested hero, Agraz did the bounce under helmet only with no suit to save time, and somehow never suffered from the bends.

Divers working over the wreck of F-4 in March 1915

An experimental 54-inch diving bell owned by the Hawaiian Dredging Company was sent for, to be rented for $750 per diem.

On 27 March, two days after F4’s dive to the bottom, as the Alert stood by some 500 feet from the lost submarine in water just 160 feet deep, the tugs USS Navajo and Intrepid, accompanied by the 150-ton derrick dredge California, the latter towed by the steamer SS Claudine, arrived on scene with a plan to use a cable loop to lift F-4 and shift her close enough to the tender for divers to attach chains to her and bring her slowly to the surface via crane. The equipment involved amounted to two 110-fathom wire hawsers, with 45 fathoms of chain in the middle.

Heartache came as the clock ticked past 55 hours with F-4 submerged and the cable loop, which had reportedly managed to lift the boat from the bottom, slipped and the submarine careened back to the floor, bow first. The sweep brought to the surface a piece of brass from the submarine’s fairwater, believed to be a section of one of her periscopes.

With the desperate rescue making headlines across the country, SECNAV Josephus Daniels ordered a Navy-wide task force to head to Hawaii and join the effort. From the New York (Brooklyn) Navy Yard, one of the first dive medicine experts, Passed Asst. Surgeon George Reuben Williamson French, USN, (UPenn ’08) was dispatched by express train to Mare Island. French brought five of the Navy’s most experienced divers: Warrant Gunner George D. Stillson and GMCs Stephen J. Drellishak, Frank Crilley, Frederick Nielson, and William Loughman.

The men had spent the past 28 months in a program to evaluate diving tables based on English Dr. John S. Haldane’s theories on staged decompression. The divers had previously reached the amazing depth of 274 feet in experimental tests from the destroyer USS Walke (DD 34) in the relatively sheltered waters of Long Island Sound, developing the first U.S. Navy Diving Manual (the 252-page “Report on Deep Diving Tests”) in the process.

The team had developed a three-wire telephone connection for the divers to remain in constant contact topside the entire dive. It was dubbed the Stillson Phone for years.

Oh, yeah, and they also helped vet and design the iconic Mark V diving rig, adopted in 1916, based on the British Siebe-Gorman 6-bolt diving helmet but with significant improvements. Air was supplied to the divers from charged torpedo flasks, with pressure controlled through a reducing valve and by throttling.

This dive was one of a series of deep diving tests conducted in Long Island Sound in late October and early November 1914. NH 99838

The dive team traveled with 10,756 pounds of specialized equipment in 27 crates, including a large recompression tank and 1,450 feet of air hose. Another 700 feet of hose was rushed from Norfolk. Mare Island was able to scrounge an additional 500 feet. Daniels dutifully told the press in Washington that, using “special appliances,” he was confident they could reach F-4. This would be their first practical test of their experimental diving techniques and what could be accomplished under service conditions.

Still, Daniels noted, “The Department fears there is not room to hope for the lives of the crew but is determined to do all that is humanly possible to raise the vessel and is undertaking to send the Navy divers to an unprecedented depth if necessary to accomplish this.”

Arriving at Mare Island, they boarded the armored cruiser USS Maryland (ACR-8), which in the meantime had been filled with six lifting pontoons- capable of lifting 520 tons- to be used in the salvage attempt.

The cruiser, the experimental dive team, and their accumulation of gear arrived in Hawaii on 12 April, sadly 18 days after F-4 was lost.

In the meantime, back at Pearl, RADM Charles B. T. Moore (commandant of the naval station), LT. Charles E. Smith (1st SubGrp skipper) and Naval Constructor Julius “Dutchie” Furer had been working on a series of mechanical lifts and sweeps to try to secure F-4, with the tugs Navajo and Intrepid joined by the dredge Gaylord.

On 7 April, with the experimental dive team still a week away, dragging continued with the tugs Navajo and Intrepid.

Furer acquired two mud scows from the Hawaiian Dredging Company, each some 104 feet long by 36 feet beam by 13 feet deep, and rigged them with four slings “made from the heaviest cables procurable” attached to purpose-built windlasses on each vessel. The windlass drums were made from 16-inch diameter sugar mill shafts and spooled with 2.5-inch galvanized steel cables obtained from the Pacific Mail Steamship Company with the 10-inch by 14-inch steam engine, geared to 6 drums, on the dredge used to reel.

With the dive team from Brooklyn arriving on the scene on 14 April, GMC Frank Crilley was the first diver to reach the submarine, dropping to a new record of 288 feet of seawater, and walked along the boat’s upper deck. He found F-4 on a smooth sandy bottom with no coral growth to impede hoisting operations, and her bow pointed shoreward. He noted two parted lines from previous snagging and recovery efforts attached to the craft. The dive took two hours, with a five-minute descent, 12 minutes on the bottom, and the balance on the slow rise to the surface to decompress.

Stillson, following immediately after, reported the superstructure was caved in, and the hull under it was filled with water.

The salvage equipment devised and employed by Furer to lift F-4 to the surface was slowly attached to the vessel over the next several days, with the divers only able to work 15-20 minutes per dive due to the exertion of working at such depth and the prerequisite decompression time. At least 13 dives went past 275 feet in depth, with five reaching the sea floor at 306 feet, struggling with 10 atmospheres of pressure (130-140 pounds per sq. inch).

To say this was dangerous for the divers was an understatement.

On 17 April, one of the men, Loughman, almost perished, adding his soul to the 21 already lost on the submarine. Entangled in lines on his ascent, he was trapped more than 250 feet down and helpless. Chief Crilley, who had already dived that day, volunteered to don a helmet and return to the deep to help his shipmate return to the surface.

Loughman, who spent more four hours at depths over 200 feet, was brought to the surface in semi-conscious conditions and had to spend nine hours in the recompression chamber, then was waylaid for two weeks with severe pneumonia and Caisson’s disease (the Bends). He was only released from Mare Island Naval Hospital at the end of June.

Dr. French on Loughman, via the 1916 Naval Medical Bulletin:

Crilley would later (in 1929!) receive a rare peacetime MoH for his actions.

Medal of Honor citation of Chief Gunner’s Mate Frank W. Crilley (as printed in the official publication “Medal of Honor, 1861-1949, The Navy”, page 106):

“For display of extraordinary heroism in the line of his profession above and beyond the call of duty during the diving operations in connection with the sinking in a depth of water 304 feet, of the U.S.S. F-4 with all on board, as a result of loss of depth control, which occurred off Honolulu, T.H., on 25 March 1915. On 17 April 1915, William F. Loughman, chief gunner’s mate, United States Navy, who had descended to the wreck and had examined one of the wire hawsers attached to it, upon starting his ascent, and when at a depth of 250 feet beneath the surface of the water, had his life line and air hose so badly fouled by this hawser that he was unable to free himself; he could neither ascend nor descend. On account of the length of time that Loughman had already been subjected to the great pressure due to the depth of water, and the uncertainty of the additional time he would have to be subjected to this pressure before he could be brought to the surface, it was imperative that steps be taken at once to clear him. Instantly, realizing the desperate case of his comrade, Crilley volunteered to go to his aid, immediately donned a diving suit, and descended. After a lapse of time of 2 hours and 11 minutes, Crilley was brought to the surface, having by a superb exhibition of skill, coolness, endurance and fortitude, untangled the snarl of lines and cleared his imperiled comrade, so that he was brought, still alive, to the surface.”

Slowly, using manila reeving line, by 18 April, all four lifting hawsers had been placed and transferred to the scows, but F-4 remained stubbornly on the bottom, drawn closer to shore into a shallower 275 feet depth.

Re-rigging the lifting hawsers with lengths of Maryland’s 2⅝-inch stud-link anchor chain for extra strength and reinstalling them, the next lift was tried on 20 May. Over the next four days, through a complicated series of lifts and tows, with the tugs, scows, pontoons, and dredge all working together day and night, F-4 had been lifted to a depth of just 84 feet by 24 May and 50 feet by 25 May. The plan was to bring her into a flooded dry dock that allowed a depth of 25.5 feet.

Then came a three-day storm that buffeted the lifting vessels and translated down the hawsers to the suspended water-filled submarine below as diving and salvage operations were suspended. When Furer sent divers down on 29 May after the waters calmed, it was found that the top of the sub was caved in and torn almost halfway through to the keel.

With F-4 upside down, suspended 46 feet under the water by hawsers, it was decided to transfer the rest of the lift to the six submergible pontoons and bring the submarine to the surface before transfer to a dry dock. Twenty charged torpedo air flasks were installed on a coal barge, then linked by pipe and a dozen 150-foot lengths of hose to the pontoons to bring them to the surface, with F-4 along for the ride. This took until 29 August to set up.

Then the lift started, with the flasks charging the pontoons and F-4 rising slowly. Importantly for diving history, this segment saw one of the first uses of several divers connected to the surface via telephone line for communication to coordinate the careful rise as one pontoon, rising too slow or too fast or at the wrong angle, could upend the whole operation.

Towed into port with the pontoons surfaced, F-4 was finally transferred to the dry dock of the Island Steam Navigation Company at the Quarantine Station dock.

McPherson, 1972. NH 74735

It was determined that the loss occurred due to leaking battery acid that corroded F-4’s hull rivets in the port wall of the battery steel tank at Frame 51, which allowed progressive flooding, chlorine off gassing due to salt water interaction with the battery jars, loss of depth control, and eventual catastrophic hull failure. This led to design changes in future submarine classes.

The salvage of F-4 is well covered in more detail at PigBoats.com. 

Epilogue

Of the 21 members of F-4’s crew that went on her last dive, 18 were recovered from her wreckage.

A team of physicians assembled from the Maryland’s medical department led by Surgeon H. Curl and Asst. Dental Surgeon Halleck, joined by Asst Surgeon WW Cress of the Alert, and Surgeons Trotter and Seaman of the Marine Hospital in Honolulu combed through the wreckage for remains.

The interior of the submarine, having been submerged for six months in the tropics, was in bad shape.

Detailed by Seaman in the 1916 Naval Medical Bulletin:

Four sets of remains were found in the middle compartment of F-4, while the rest were found in the stern engine compartment. Of the four recovered that were identifiable, two, Ashcroft and Herzog, were identified due to dental records, while the other two, Wells and Mahan, were identified due to the contents of their pockets. The remains were wrapped in cotton, surrounded by oakum, and placed in caskets.

The four who were able to be identified were repatriated to their families for interment, sent to California, Utah, and Virginia.

The 14 unidentified sets of remains were arranged in four sealed metal coffins, marched in a somber funeral parade through Honolulu to the California-bound USS Supply, and were eventually buried with honors at Arlington.

The modern marker for the F-4 crew includes the 14 men buried and three missing

Her crew is remembered as the first of the American submarines listed on Eternal Patrol and appear on markers and monuments as such across the country.

Following the investigation of her doom and the removal of remains, the wreckage of F-4 was refloated on 15 September 1915– the dry dock was rented after all– and towed under the pontoons by Navajo into Magazine Loch until she grounded in the shallow inlet. There she sat in the shallows until 1940 when the area was turned into the Sierra submarine piers. She was rolled into a trench by the pier and buried.

In 1999, a magnetometer survey near pier Sierra 13/14 detected a large object, some 80 feet from the pier, under some 20 feet of sediment. A sign has since been erected to note this resting place.

Meanwhile, the small original headstone for her 17 crew members buried at Arlington was installed at the USS Bowfin Museum at Pearl.

Some of her construction notes endure in the National Archives. 

In November 1915, Dutchie Furer, who directed the recovery of F-4, largely with improvised equipment, submitted an extremely detailed article on the salvage operation to Proceedings. A 1901 Annapolis grad who fought against the Spanish in 1898 while still a midshipman, he was a proponent of small craft operations and campaigned successfully for the 110-foot subchasers in the Great War. Earning a Navy Cross, he later helped supervise the modernization of the battleships USS Pennsylvania and New Mexico in the 1930s and, still on duty in 1941, became Chief of Navy Research and helped coordinate new technology into the fleet in WWII. He retired in November 1945.

RADM Julius Augustus Furer, USNA ’01, passed in 1963, aged 82, and is buried at Arlington.

Likewise, Dr. French would publish “Diving Operations in Connection with the Salvage of the USS ‘F-4″ in the Naval Medical Bulletin in 1916. He retired from the navy as a commander in 1937, then returned to the colors during WWII, later passing at the Oakland Navy Hospital in May 1955. He is regarded as the Navy’s first Diving Medical Officer. 

The hard hat divers of the experimental team that set and repeatedly broke their own deep-sea records also kept at it.

When there was another accident in 1927, when the USS S-4 (SS-109) became disabled and was lost with all hands, a familiar face hit the news again, with now-Ensign Grilley again earning a peacetime decoration for bravery.

“Naval divers who worked hard and faithfully at the difficult task of raising the submarine S-4” (quoted from the original 1928 caption). Probably photographed at the Boston Navy Yard, Charlestown, Massachusetts, circa 19-20 March 1928, shortly after the salvaged S-4 entered dry dock there. Those present are identified in the original caption as (standing, left to right): Michaels, Eadie, Wilson, Carr, and Eissn. (Kneeling, left to right): Grilley, Mattox and Doherty. Michaels may be Chief Torpedoman Michels. Eadie is Chief Gunner’s Mate. Thomas Eadie, who was awarded the Medal of Honor for rescuing Michaels during salvage work. Grilley is probably Ensign Frank W. Crilley. NH 41836

Navy Cross citation of Ensign Frank W. Crilley (as printed in his official biography):

“For extraordinary heroism and fearless devotion to duty during the diving operations in connection with the salvage of the USS S-4, sunk as a result of a collision off Provincetown, Massachusetts, 17 December 1927. During the period 17 December 1927 to 17 March 1928, on which latter date the ill-fated vessel was raised, Crilley, under the most adverse weather conditions, at the risk of his life, descended many times into the icy waters and displayed throughout that period fortitude, skill, determination and courage which characterizes conduct above and beyond the call of duty.”

Ensign Frank William Crilley, who earned both the Navy Cross and MoH, the latter only presented in 1929 by Coolidge some 14 years after the fact, retired from the service at least twice and was called back to help salvage lost subs. He passed in 1947, aged 64, on dry land. He is buried at Arlington.

The current Navy Experimental Diving Unit was formally established in 1927 at the Washington Navy Yard and the equipment and procedures developed at NEDU, including the McCann Rescue Chamber and mixed gas diving, were essential to the rescue of the crewmen who survived the initial sinking of the submarine USS Squalus on the bottom off the Isle of Shoals near Portsmouth in 1939.

The disabled Squalus was located on the sea floor at a depth of 240 feet in 29°F water, and a rescue ship with a diving chamber came to the site. The 33 crew in the non-flooded compartments were transferred to the surface within 40 hours via four trips of the diving chamber.

Now moving towards its 100th year in operation, the NEDU, still under SUPSALV, continues its research to save lives in the worst-case scenario.

They retain the Mark V on their insignia.

Holy Loch North

One of the aces in the hole for the old-school Polaris Fleet Ballistic Missile submarines and their Trident descendants was Refit Site One, hidden in Holy Loch, Scotland near the Firth of Clyde.

Established as the forward base for SUBRON 14 around the tender USS Proteus (AS-19) and floating dry dock Los Alamos (AFDB-7) in 1961 with a small shoreside footprint, the tenders and SSBNs changed but Los Alamos endured and the base quietly closed after the thaw in the Cold War in 1991, capping its 30-year mission.

Well, with Holy Loch long gone and the sub force still in need of some quiet out-of-the-way places to make occasionally needed pit stops on the surface, Iceland has become a friend indeed. Since April 2023, six SSNs– important to the Icelandic government nuclear-powered but not “officially” carrying nuclear weapons– have slipped into Eyjafjordur– a huge fjord in Northcentral Iceland some 15km wide and 60 km long, dotted by a few small villages and the town of Akureyri (pop 19,000)– for partial resupply and crew swaps.

For their part, Iceland provides logistical support and local security in the form of the cutters and crews of the Icelandic Coast Guard.

The ICG’s cutter Freyja recently assisted with one such service of one of SUBRON 12’s Block III Virginia-class hunter-killers, USS Delaware (SSN 791), over the weekend.

Via the ICG:

The service visits are part of Iceland’s defense commitments and an important contribution to the joint defense of the Atlantic Union. Their deployment here on land allows our allies to ensure continuity of surveillance, shorten response times, and send messages of presence and defense in the North Atlantic.

Meanwhile, down under…

In related news on the other side of the globe, the SUBRON15’s Guam-based Virginia-class hunter-killer USS Minnesota (SSN 783) arrived in sunny Western Australia on February 25, 2025, kicking off the first of two planned U.S. fast-attack submarine visits to HMAS Stirling at Freemantle in 2025.

Hr.Ms. K XI, found

Dutch Onderzeeboot Hr.Ms. K XI at Satonda, Nederlands-Indië, March 1931. She was the class leader of a trio of 218-foot 800-ton “colonial” submarines of the Royal Netherlands Navy, so-called as they were based out of Soerabaja on Java. (NIMH 2158_007091)

Western Australia-based non-profit WreckSploration reports having recently discovered the final resting place of the WWII-era Dutch submarine Hr.Ms K XI (N 53) off the coast of Rottnest Island.
Launched in April 1924, HNLMS K XI served in the Dutch East Indies during WWII, patrolling the waters of what is now Indonesia from its base in Surabaya.
In 1942, the submarine played a heroic role, rescuing 18 survivors of the lost sloop HMAS Yarra (U77), the British depot ship HMS Anking, and the KPM steamer Parigi after they were sunk by an overwhelming Japanese force.
In all, she completed seven war patrols in the Pacific and, perhaps more importantly, spent months working out of Bombay and Colombo as a “tame submarine” for Allied ASW forces to hone their skill on.
After being decommissioned in Fremantle in 1945, K XI was scuttled in 1946, its final resting place lost to time – until now.

T-AGSEs Surface

An interesting addition to the Bollinger-built 87-foot Marine Protector class patrol boats for the Coast Guard in 2008 was four units– paid for wholly by the Navy– that would serve in two special Maritime Force Protection Units, assigned to the Submarine bases at Kings Bay and Kitsap, tasked to escort submarines (particularly SSBNs) heading in and out on patrol.

Each MFPU, which numbers 150-200 personnel, also has a dozen smaller craft (33-foot RIBs, etc).

In a nod to their taskings, these Navy-paid-for/assigned and CG-manned patrol boats carried the names of historic fleet boats of WWII fame:

  • USCGC Sea Dragon (WPB-87367) MFPU Kitsap
  • USCGC Sea Devil (WPB-87368) MFPU Kings Bay
  • USCGC Sea Dog (WPB-87373) MFPU Kitsap
  • USCGC Sea Fox (WPB-87374) MFPU Kings Bay

Armed with three 50 cal. machine guns (instead of the standard two for the class) these MFPUs carried their “extra” BMG in a permanently installed forward mount that was stabilized and remotely controlled.

However, last year all four of these still rather young WPBs were withdrawn from CG service, decommissioned, disarmed, and relegated to auxiliary service with the Navy and Marine Corps.

For instance, the two Kings Bay-based boats were transferred to MCAS Cherry Point, North Carolina to be used as range/target towing boats.

Their replacements?

Meet T-AGSEs

The civilian mariner crewed Military Sealift Command has a small flotilla of eight vessels tasked with “Submarine and Special Warfare Support.”

These vessels, typically oilfield supply boats operated by Louisiana-based Hornbeck Offshore Services, include a quartet of 250-foot EDF type who have been christened as U.S. Naval Ships with hull numbers.

They also carry fixed armament, something extremely rare for the MSC, namely two Mk. 38 25mm mounts, operated by a USCG Tactical Boatcrew. I wouldn’t be surprised if they had MANPADs, AT4s, and M2s stowed as well

  • USNS Black Powder (T-AGSE 1)
  • USNS Westwind (T-AGSE 2)
  • USNS Eagleview (T-AGSE 3)
  • USNS Arrowhead (T-AGSE 4)

Built by Leevac Industries of Jenerette, these four brand-new 250EDFs were operated by HOS between 2009 and 2015 on a Navy contract and then purchased outright for $152 million.

The MSC has their file pictures all still in their HOS livery:

HOS Black Powder 200819-N-IS698-0004

HOS Eagle View 200819-N-IS698-0007

HOS Arrowhead

Since 2015, these craft have been Navy (MSC) owned and operated by HOS, typically for 215 days per year at a rate of about $30,000 per day.

Arrowhead and Eagleview are out of Kitsap while Black Powder and Westwind are out of Kings Bay.

Being some 250 feet in length, they are often referred to as “Blocking Vessels” in operations.

They rarely get any attention, with the USCG operating their guns and providing an MLE team for intervention/boarding if an escort gets…weird. Why the Coasties pull the gig is that they are federal law enforcement with a pretty far-reaching jurisdiction around U.S. flagged vessels in U.S. waters.

Ohio class USS West Virginia (SSBN-736) USNS Black Powder

U.S. Air Force A-10 Thunderbolt II aircraft from Moody Air Force Base, Ga., escorted ballistic missile submarine USS Wyoming (SSBN 742), July 15, 2024. The aircraft conducted a live fire exercise and U.S. Coast Guard Maritime Force Protection Unit Kings Bay, USNS Black Powder (T-AGSE-1), and USNS Westwind (T-AGSE-2) also participated in the escort of the submarine. Joint operations, such as this one which involved the Air Force, Coast Guard, and Navy, ensure the U.S. military is ready to meet its security commitments at home and abroad

Being three times the size of the 87s, they can also help serve as mini-tenders and, during Covid, were used to swap out Blue/Gold crews on SSBNs at sea, as well as replenishment for parts and stores transfers via a moving brow.

Note the USCG ensign on Black Powder’s mast and her USNS designator on her bow.
