The desperate search for the ARA San Juan

This undated photo provided by the Argentina Navy shows an ARA San Juan, a German-built diesel-electric submarine, near Buenos Aires, Argentina. Argentina’s Navy said Nov. 17, 2017, it has lost contact with its ARA San Juan submarine off the country’s southern coast. (Argentina Navy)

The Argentine Navy submarine ARA San Juan (S-21) is currently missing inside a 482,507 sq.km area to the east of Argentina, north of the Falklands, while on a scheduled trip from the naval base at Ushuaia in Argentina’s extreme south to Mar del Plata. Her closest point to land is estimated to be about 200 miles offshore in 500-700m of the coldest and most inhospitable waters on earth.

The search area is being scoured by ships and aircraft from her home country (to include vintage but still effective S-2 Trackers), as well as Chile, Peru, South Africa, Brazil, the Royal Navy (a C-130 out of Port Stanley and the ice patrol ship HMS Protector), and the U.S.– the later of which has provided at least two Navy P-8A Poseidon multi-mission maritime aircraft, a number of UUVs, and a NASA P-3B research aircraft which still has its MAD sensor equipment.

The RN’s Submarine Parachute Assistance Group, NATO’s submarine rescue unit as well as two assets from the U.S. are staging to effect an emergency rescue is needed:

Three U.S. Air Force C-17 Globemaster III and one U.S. Air Force C-5 Galaxy aircraft will transport the first rescue system, the Submarine Rescue Chamber (SRC) and underwater intervention Remotely Operated Vehicle (ROV) from Miramar to Comodoro Rivadavia, Argentina. The four aircraft are scheduled to depart Miramar Nov. 18 and arrive in Argentina Nov. 19.

The second rescue system, the Pressurized Rescue Module (PRM) and supporting equipment will be transported via additional flights and is scheduled to arrive in Argentina early next week.

The SRC is a McCann rescue chamber designed during World War II and still used today. SRC can rescue up to six persons at a time and reach a bottomed submarine at depths of 850 feet. The PRM can submerge up to 2,000 feet for docking and mating, with a submarine settled on the ocean floor up to 45-degree angle in both pitch and roll. The PRM can rescue up to 16 personnel at a time. Both assets are operated by two crewmembers and mate with the submarine by sealing over the submarine’s hatch allowing Sailors to safely transfer to the rescue chamber.

Waves 4,5 meters in height and winds of 90 km are hampering the search.

While some attempted satellite communications attempts may have been made by the San Juan on Saturday, there has been no contact with the vessel since Thursday.

The San Juan, a West German-built Thyssen Nordseewerke TR-1700 type diesel-electric sub (a design used only by Argentina) was commissioned in 1985 and was most recently refit in 2014. The two completed TR-1700s were basically stretched Type 209 SSKs designed in the 1970s and, while four were to be constructed– half in Germany/ half in Argentina– just the pair of European subs were completed.

As the San Juan was built to NATO-specs, the dive rescue chambers being rushed to the area should prove compatible if she is located in time and the pressure hull is intact.

Organized first with students who were trained in the U.S. in 1917, the Escuela de Submarinos received their first three submarines– Italian Tosi-built boats– in the 1930s. Since then the force has operated four Balao-class fleet boats and two Type 209 submarines, with one of each of the latter types, saw service in the Falklands conflict.

At least 44 servicemen on board the missing submarine. Among the crew is South America’s first female submarine officer, Eliana María Krawczyk, who joined the Armada in 2009 and was accepted into the Escuela de Submarinos in 2012.

Please keep them all in your thoughts and prayers.

Onyx on the rocks, err ‘impact hydrography’

While the RN committed a number of sexy modern nuclear-powered attack submarines to the Falkland Islands conflict in 1982– and they proved effective in making the Argentine Navy return to port after HMS Conqueror sank the WWII-era cruiser ARA General Belgrano with 323 lost at sea (among the bulk of that service’s losses in terms of humans on the butcher’s bill)– there was one creepy little diesel boat poking around close to shore.

El Snorkel has a great article from Lt Cdr Andy Johnson Submarine, Commander HMS ONYX (S21) during the conflict. An Oberon-class submarine, she was but 241-feet long and weighed only 2,400-tons, smaller than a WWII U.S. Navy fleet boat.

Commissioned in 1967, she had a cramped crew of 6 officers and 62 men and made the slow transit from the UK some 8,000nm south to the Falklands MEZ with a special 5 man diving chamber 10 MK 24, 2 Mk 20 and 11 Mk 8 torpedoes aboard.

She stopped halfway at windswept Ascension and picked up a team of British frogmen, flown ahead to await their ride south.

At Ascension Island, 12 May 1982, ONYX boarded SAS and SBS special forces personnel and supported them during a series of operations. IWM photo

Her shallow operating depth allowed her to creep in close to shore for commando and surveillance work in relatively uncharted areas where a nuke boat would be hard pressed. Officially, “her ability to operate silently close inshore enabled her to play an important role. In addition to providing a submarine deterrent and enforcing the exclusion zone surrounding the Islands, ONYX undertook reconnaissance, taking periscope photographs of enemy installations and likely landing areas for Special Forces operations.”

And it was sometimes very hairy.

From Johnson:

An effort to complete a reconnaissance mission at short notice nearly ended the patrol. Many of the charts used to navigate in those waters had not changed significantly since James Cook had first drawn them. The occasional soundings he made at that time were undoubtedly adequate for his small sailing vessel. They scarcely matched the requirements of a 2,500 ton submarine two centuries later. In consequence, ONYX discovered an uncharted pinnacle of rock in a most dramatic fashion – by running in to it whilst dived. Although everyone reacted admirably and control was quickly regained, it is probably safe to say the only people on board who appeared really calm were our ‘guests’ from special forces. Not entirely due to their steel nerves – no-one had time to explain to them what had happened! This piece of ‘impact hydrography’ put two out of the six forward torpedo tubes out of action. This was serious enough in itself, but was made worse since the two affected tubes were those used exclusively for wire guided torpedoes. As a result, the fore-ends’ crew had to reorganise our full torpedo load. This was akin to playing solitaire. However, they first had to make a free ‘hole’ by moving tons of additional equipment out into the rest of the submarine. Even then there were still weapons weighing tons suspended in mid-air as the reshuffle continued.

The rest here.

Warship Wednesday, Oct. 25, 2017: Putting the ‘Marine’ back in submarine

Here at LSOZI, we are going to take off every Wednesday for a look at the old steam/diesel navies of the 1859-1946 time period and will profile a different ship (in this case, doctrine) each week. These ships have a life, a tale all of their own, which sometimes takes them to the strangest places. – Christopher Eger

Warship Wednesday, Oct. 25, 2017: Putting the ‘Marine’ back in submarine

On 17 August 1942, just nine months after Pearl Harbor, 211 Marines of the 2nd Marine Raider Battalion embarked aboard the submarines USS Argonaut and Nautilus crept ashore at Makin Island and did what the Raiders were meant to do– hit hard in the most unexpected area they could find and jack up a small Japanese garrison.

While that attack was the pinnacle of U.S. submarine commando ops in WWII, and the Raiders were disbanded by early 1944, the Marines did not forget the concept of amphibious scouts and small raiding forces carried by submarines when the war was over.

Scouts and Raiders Painting, Oil on Canvas; by Carlos Lopez; C. 1943; Framed Dimensions 29H X 44W Accession #: 88-159-HD as a Gift of Abbott Laboratories “Commandos of the Navy, they leave a transport, submarine, or invasion craft in their black rubber boats at night on reconnaissance, scout, or demolition missions against enemy-held shores. Their faces and hands painted black for night operations, and now called officially Amphibious Scouts by the Navy, they specialize in rugged finesse. Here they go up and over some rock jetties.”

In 1948, the Marines pushed to convert a dozen Balao-class fleet subs into auxiliary Submarine Troop Carriers (ASSPs) which would involve removing all the torpedo tubes (the Navy loved that idea) as well as two of the big main diesels and using the new-found space to install extra bunks, showers and a pressure-proof hangar mounted outside of the pressure hull on deck. These subs would be able to carry 120 troops including an LVT with a jeep and equipment stowed aboard and eight rubber raiding rafts.

Yes, this IS a submarine with an Amtrac aboard. Perch (ASSP-313) preparing to launch an LVT amphibious tractor during a 1949 exercise. The vehicle could be carried in the cargo hangar and launched by flooding down the submarine. USN photo and text from The American Submarine by Norman Polmar, courtesy of Robert Hurst.

In theory, these boats could lift an entire reinforced battalion landing team with four 75mm Pack Howitzers, six 57mm recoilless rifles, 12 jeeps, 12 LVTs, 48 boats, 220 tons of ammo and ordnance; and 158 tons of supplies– enough to operate for ashore for ten days.

Bad news for the USMC was that the Navy just converted two of the subs– USS Perch (SS-313) and USS Sealion (SS-315). While they were later used extensively to support the Navy’s own UDT operations through the Vietnamese conflict, they didn’t come close to realizing the Marine’s vision in 1948.

Nonetheless, the Marines continued to trial submarine operations with smaller teams of amphibious recon troops in the 1950s, as seen in these great images:

The submarine above is USS Greenfish (SS-351). Greenfish was a Balao-class fleet sub commissioned 7 June 1946, too late for WWII. She did, however, perform duty during the Korean and Vietnam wars and, after she was decommissioned in 1973, was transferred to the Brazilian Navy as the submarine Amazonas (S-16), who kept her in service for another 20 years before she was ultimately scrapped in 2001. In U.S. service, Greenfish sank two submarines in her career, the captured U-234 in 1947 and her sister ship and former Warship Wednesday alumni USS Barbero (SS/SSA/SSG-317) off Pearl Harbor, Hawaii, on 7 October 1964 after that ship was stricken.

The tradition of the Raiders and their use from submarines continues in the modern-day Raiders, recon teams and, of course Navy SEAL units who utilise a number of dedicated boats including the Seawolf and modified Ohio-class SSGNs when they are feeling particularly froggy as well as the organic Combat Rubber Raiding Craft companies built into to each of the seven Marine Expeditionary Forces.

NATO’s submarine rescue service

A pretty interesting video on the NATO Submarine Rescue System (NSRS) is a cooperative project between three NATO countries: France, Norway and the United Kingdom.

“It is designed to rescue personnel from submarines in distress and can dive to depths of up to 600 meters. It consists of three main parts: an intervention system, a rescue vehicle and a transfer under pressure system. It is the largest fly-away submarine rescue system and can dive up to six hours, four times a day. On each dive, it can rescue approximately 12 submariners, who will receive medical treatment in its facilities, if needed. The NATO Submarine Rescue System is available to anyone on request and can be deployed almost anywhere in the world within 72 hours.”

On the downside, while it is ideal for plucking bubbleheads from wrecked Type 209s and the like, running to pick up a 100+ member crew from a U.S. sub would likely push the NSRS to its limit.

The Navy used to have a very robust rescue program of its own, two DSRV’s (Mystic and Avalon) each able to rescue 24 men at a time. Operating from the purpose-built rescue ships USS Pigeon and USS Ortolan, all have since been decommissioned and replaced by the single 16-place Submarine Rescue Diving Recompression System, which is turn is based on the 6-passenger Royal Australian Navy Submarine rescue vehicle Remora and uses craft of opportunity.

Here we see the Balao-class diesel-electric fleet submarine USS Tilefish (SS-307) returning to San Diego on 5 December 1958 for inactivation. You may not recognize her in the photo, but she was always ready for her closeup.

A member of the 128-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. U.S. subs, unlike those of many navies of the day, were ‘fleet’ boats, capable of unsupported operations in deep water far from home.

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 5000-ton Maru or warship by surfacing and using their 4-inch/50 caliber and 40mm/20mm AAA’s. The also served as the firetrucks of the fleet, rescuing downed naval aviators from right under the noses of Japanese warships.

We have covered a number of this class before, such as Rocket Mail slinging USS Barbero, the carrier-sinking USS Archerfish, the long-serving USS Catfish and the frogman Cadillac USS Perch —but don’t complain, they have lots of great stories.

Laid down at Mare Island Navy Yard in Vallejo, California, on 10 Mar 1943, USS Tilefish was the first and only naval vessel named for homely reef fish found in the world’s oceans.

Commissioned just nine months later on 28 Dec 1943, Tilefish completed her trials and shakedown off the California coast and made for the Western Pacific in early 1944.

Her first war patrol, off Honshu in Japanese home waters, was short and uneventful.

Her second, in the Luzon Strait, netted a torpedo hit on the 745-ton Japanese corvette Kaibokan 17 south of Formosa on 18 July.

Her third patrol, in the Sea of Okhotsk and off the Kuril Islands, resulted in sinking a sampan in a surface action, as well as two small cargo ships, a larger cargo ship and the 108-ton Japanese guard boat Kyowa Maru No.2. Tilefish also picked up a Russian owl in these frigid waters, which was duly named Boris Hootski with the ship’s log noting, “He is now official ship’s mascot and stands battle stations on top of the tube blow and vent manifold.”

She closed the year with her fourth patrol in the Kurils and Japanese home waters with sinking the Japanese torpedo boat Chidori some 90 miles WSW of Yokosuka.

Early 1945 saw her fifth patrol which sank a small Japanese coaster and effectively knocked the IJN minesweeper W 15 out of the war. She also plucked LT (JG) William J. Hooks from the USS Hancock (CV-19) of VF-80 out of the water after he had to ditch his F6F at sea off Amami Oshima in the Ryukyus.

After refit on the West Coast, Tilefish completed her sixth patrol on lifeguard station off the Ryukyus where she ended the war, being ordered back to California on 7 September.

In all, Tilefish received five battle stars for World War II service. Her tally included 7 vessels for a total of 10,700 claimed tons– though many were disallowed post-war by JANAC. Her six patrols averaged 48 days at sea.

While most of the U.S. submarine fleet was mothballed in the months immediately after WWII, Tilefish remained in service. She even managed a sinkex in August 1947 against the crippled Liberty tanker SS Schuyler Colfax, at 7,200-tons, Tilefish‘s largest prize.

Her war flag represented as a patch from popularpatch.com. Note the 10 vessels claimed and the parachute for Lt. Hooks.

When the Korean War kicked off in 1950, Tilefish made for the region.

As noted by DANFS:

“From 28 September 1950 through 24 March 1951, the submarine operated out of Japanese ports conducting patrols in Korean waters in support of the United Nations campaign in Korea. She made reconnaissance patrols of La Perouse Strait to keep the Commander, Naval Forces Far East, informed of Soviet seaborne activity in that area.”

Tilefish received one battle star for Korean service.

Catalog #: NH 97068

The next nine years saw her conducting regular peacetime operations and exercises including a goodwill visit to Acapulco; a survey mission with four civilian geophysicists on board from the Hydrographic Office of Eniwetok, Wake, and Midway; and other ops.

These “other ops” included filming some scenes for the 1958 Glen Ford WWII submarine flick Torpedo Run, which were extensively augmented by scale models, and more extensive shoots for Up Periscope, a film in which James Garner, a Korean war Army vet and Hollywood cowboy, plays a frogman ordered to photograph a codebook at an isolated Japanese radio station.

The film was an adaption of LCDR Robb White’s book of the same name.

Garner was not impressed by the Tilefish.

James Garner as Lieutenant Kenneth M. Braden in Up Periscope

As related by a Warren Oaks biographer, Garner, bobbing along on the old submarine offshore at 9-kts in groundswells, said, “You know something? I’d like to be back on my horse.”

After her brief movie career and service in two wars, Tilefish was given a rebuild at the San Francisco Navy Yard and was decommissioned in May 1960.

Tilefish was then sold to Venezuela, which renamed her ARV Carite (S-11). As such, she was the first modern submarine in that force. She arrived in that country on 23 July 1960, setting the small navy up to be the fifth in Latin America with subs.

ARV S-11 Carite El 4 de mayo de 1960

As noted by El Snorkel (great name), a Latin American submarine resource, Tilefish/Carite was very active indeed, making 7,287 dives with the Venezuelan Navy over the next 17 years. She participated in the Argentine/Dominican Republic/Venezuelan -U.S. Quarantine Task Force 137 during the Cuban Missile Crisis, and intercepted the Soviet tug Gromoboi in 1968.

In 1966, she was part of the Greater Underwater Propulsion Power Program (GUPPY) conversion program and (along with 20 other boats), was given the very basic Fleet Snorkel package which provided most ofthe bells and whistles found on the German late-WWII Type XXI U-boats– which would later prove ironic. This gave her expanded battery capacity, steamlined her sail conning tower fairwater into a so-called “Northern or North Atlantic sail”– a steel framework surrounded by thick fiberglass– added a snorkel, higher capacity air-conditioning system, and a more powerful electrical system and increased her submerged speed to 15 knots while removing her auxillary diesel. A small topside sonar dome appeared.

ex-Tilefish (SS-307), taken 12 Oct. 1966 after transfer to Venezuela as ARV Carite (S-11). Note the GUPPY series conversion, the so-called very basic “Fleet Snorkel” mod.

However, during this time, her most enduring exposure was in helping film Murphy’s War, in which a German U-boat (U-482) hides out in the Orinoco River in Venezuela after sinking British merchant steamer Mount Kyle, leaving Peter O’Toole as the lone survivor on a hunt to bag the German shark. The thing is, she looked too modern for the film after her recent conversion.

For her role, Carite was given a far-out grey-white-black dazzle camo scheme and, to make her more U-boat-ish, was fitted with a faux cigarette deck after her tower complete with a Boffin 40mm (!) and a twin Oerlikon mount (!!). Her bow was fitted with similarly faked submarine net cutting teeth.

Her “crew” was a mix of U.S. Peace Corps kids working in the area (to get the proper blonde Germanic look) with Venezuelan tars at the controls.

The movie, filmed in decadent Panavision color, shows lots of footage of the old Tilefish including a dramatic ramming sequence with a bone in her teeth and what could be the last and best images of a Balao-class submarine with her decks awash.

That bone!

Ballasting down– note the very un U-boat like sonar dome. I believe that is a QHB-1 transducer dome to starboard with a BQR-3 hydrophone behind it on port

By the mid-1970s, Tilefish/Carite was showing her age. In 1972, the Venezuelans picked up more two more advanced GUPPY II conversions, her Balao-class sister USS Cubera (SS-347), renaming her ARV Tiburon (S-12) and the Tench-class USS Grenadier (SS-525) which followed as ARV Picua (S-13) in 1973.

Once the two “new” boats were integrated into the Venezuelan Navy, Tilefish/Carite was decommissioned on 28 January 1977 and slowly cannibalized for spare parts, enabling Cubera and Grenadier to remain in service until 1989 when they were replaced by new-built German Type 209-class SSKs, which still serve to one degree or another.

According to a Polish submarine page, some artifacts from Tilefish including a torpedo tube remain in Venezuela.

Although she is no longer afloat, eight Balao-class submarines are preserved (for now) as museum ships across the country.

Please visit one of these fine ships and keep the legacy alive:

-USS Batfish (SS-310) at War Memorial Park in Muskogee, Oklahoma.
USS Becuna (SS-319) at Independence Seaport Museum in Philadelphia, Pennsylvania.
USS Bowfin (SS-287) at USS Bowfin Submarine Museum & Park in Honolulu, Hawaii.
USS Clamagore (SS-343) at Patriot’s Point in Mount Pleasant, South Carolina. (Which may not be there much longer)
USS Ling (SS-297) at New Jersey Naval Museum in Hackensack, New Jersey. (Which is also on borrowed time)
USS Lionfish (SS-298) at Battleship Cove in Fall River, Massachusetts.
-USS Pampanito (SS-383) at San Francisco Maritime National Historical Park in San Francisco, California, (which played the part of the fictional USS Stingray in the movie Down Periscope).
USS Razorback (SS-394) at Arkansas Inland Maritime Museum in North Little Rock, Arkansas.

However, Tilefish will endure wherever submarine films are enjoyed.

Wave glider runs tiny towed array in search for subs, mines

Meet KraitArray, a miniaturized towed array for use on drones and opvs from the UK.

It is aimed at smaller platforms such as patrol craft and OPVs that are unable to accommodate a full-sized towed array sonar.

That tail is a towed sonar array small enough to fit in a backpack

Steve Hill, Managing Director clarified:

“It is often physically and operationally impractical for smaller ships to carry a larger diameter towed line array system. KraitArray’s smaller diameter provides effective ASW capability and can be operated from a
conventional ship or unmanned assets. By integrating the sonar capability with SEA’s decoy and torpedo launchers, using common configurable software, ships can be fitted with a complete ASW solution”

The concept, shown in conjunction with a Boeing/Liquid Robotics Wave Glider, can turn a long range, low-cost UUV into a valid ASW tool.

Showing off the Proteus mini-sub packing heat

Huntington Ingalls Industries announced a couple weeks ago that Proteus, their 26-foot-long dual-mode undersea vehicle (UUV), successfully completed autonomous contested battlespace missions during the 2017 Advanced Naval Technology Exercise (ANTX) at the Naval Surface Warfare Center in Panama City Division.

And released this sweet image:

Proteus, a dual-mode undersea vehicle developed by HII_s Technical Solutions division

The Panama City News Herald has more images, including shots of the interior and control panel and underway.

As noted by the PCB NH:

Since entering the testing phase in 2012, Proteus has logged 2,000 dive hours locally and abroad, including at Naval Surface Warfare Center Panama City Division (NSWC PCD), the scientific lab for Naval Support Activity Panama City.

It can go underwater with or without a human crew, though it isn’t yet being used in field missions. At ANTX, hosted by NSWC PCD, its designers showed off another capability, having Proteus carry other vehicles during testing.
