The Matchbox RC Boats of RIMPAC

We’ve covered lots of RIMPAC 26 stuff, but some small players are easily missed.

We speak, of course, to the ever-growing array of unmanned surface vehicles present in the exercise.

First off, let’s give it up to the U.S. Navy Global Autonomous Reconnaissance Craft (GARC) USVs from USVDIV (Unmanned Surface Vessel Division) 32, which took part in the SINKEX of ex-USS Peleliu (LHA 5).

A released Navy video shows two of the boats circling the battered hulk of the 40,000-ton ‘phib– and the old Peleliu soaked up the damage for sure– before they closed in to mimic a Japanese Shinyo suicide speedboat of 1944; only the remote operators got to live.

The Black Sea Tech GARC runs 15.8 feet, can make 40 knots in a sprint, and carry a half-ton payload. Keep in mind the small boat used in the October 2000 attack on the USS Cole is believed to have carried only between 400 and 700 pounds of C-4 plastic explosives; it created a 40×40-foot hole in the DDG that nearly sent her to the bottom.

Of note, USVDIV 32 GARCs performed swarm exercises with USS Mount Whitney (LCC 20) during Baltic Operations (BALTOPS) 2026 last month.

Besides the GARCs, a “digitally controlled surface vessel” (DCSV) launched from Sand Island, near Honolulu, delivered equipment for a 3D printer aboard Wasp-class amphibious assault ship USS Essex (LHD-2), completing what organizers describe as the “Department of the Navy’s first digitally-crewed surface vessel resupply of a Navy ship.”

Following the delivery, the DCSV continued its mission by transporting drone components to the 25th Infantry Division’s Lightning Lab, where Marines and Soldiers assembled the systems before deploying them for testing at Makua Range. From manufacturing and maritime delivery to assembly and operational employment, the end-to-end process was completed in less than 24 hours.

Not sure exactly what this thing is, but it has a very low-profile vessel (LPV) narco-sub flavor.

There was also a Splash Industries Typhoon used in the Essex delivery mission.

The sizzle reel of the DCSV headed to Essex:

Keep in mind that the Navy is getting real-time combat feedback from their USV fleet as well, with at least three Saronic Corsair USVs laden with explosive packages used against an Iranian submarine at the port of Bandar Abbas earlier this month.

Coast Guard shifts PATFORSWA to Westpac, ends 24 Year Persian Gulf Mission

With the Navy being patrol-craft-poor during OIF in the summer of 2002, Big Blue asked its poor uncle, the USCG, to temporarily shift a few 110-foot Island-class patrol boats to CENTCOM control in Bahrain.

Soon after, four East Coast-based Islands, USCGC  Adak, Aquidneck, Baranof, and Wrangell, were carried via heavy lift vessel to the Persian Gulf and eventually became Patrol Forces Southwest Asia (PATFORSWA) while four others, USCGC Bainbridge Island, Grand Isle, Knight Island, and Pea Island, were shifted to the Mediterranean as PATFORMED.

While the Med mission evaporated by 2004 due to Turkey not wanting to help support OIF and was stood down, those four cutters sent TDY to PATFORSWA never saw the U.S. again and were decommissioned there decades later, the force augmented to a full six-pack with the addition of Island-class sisters, USCGC Maui and Monomoy.

Antietam completed fuel replenishment with the Monomoy in about two hours and saved the 110-foot patrol boat a four-hour trip to the nearest refueling station.

The force was recently refreshed with six brand-new 154-foot Sentinel-class cutters: USCGC Charles Moulthrope, Robert Goldman, Glen Harris, Emlen Tunnell, John Scheuerman, and Clarence Sutphin Jr arriving, and the old Islands disposed of in-theatre.

The cutters are forward-deployed to U.S. 5th Fleet to help ensure maritime security and stability across the Middle East. (U.S. Army photo by Spc. Noah Martin)

Now, with the NWU-camo wearing 300-member force (six cutters, an extra crew, and 150 shoreside personnel) pulled out of the Gulf ever since February, as the 154s aren’t really built to operate against non-stop drone attacks, it seems the Navy finally threw in the towel on PATFORSWA’s mission and is shifting them to where they can win more hearts and minds, the Western Pacific.

From USCG PAO:

The United States Coast Guard transitioned its Expeditionary Cutter Squadron (ECS), historically called Patrol Forces Southwest Asia (PATFORSWA), to operate in the Western Pacific conducting maritime security operations and cooperative maritime activities with allies and partner nations in the region, in response to national security requirements.

The Expeditionary Cutter Squadron will be capable of performing missions as part of the U.S. Joint Force. The squadron is currently operating in the U.S. Pacific Command area of operations to protect the homeland and maritime approaches, including Guam and the Pacific Islands.

For more than 20 years, the Coast Guard has provided forward-deployed capabilities to support U.S. Central Command and U.S. Naval Forces Central Command from Bahrain. The unit has successfully executed maritime security, maritime interdiction, and maritime domain awareness missions throughout the Middle East.

“Coast Guard forces have always adapted to meet urgent national needs,” said Adm. Kevin Lunday, Commandant of the Coast Guard. “The Expeditionary Cutter Squadron enhances the Coast Guard’s ability to deploy our forces in support of Combatant Commanders and national security objectives. Our expeditionary cutter forces provide Combatant Commands with uniquely capable maritime assets, leveraging the Coast Guard’s military and law enforcement authorities to advance U.S. national security objectives in the Western Pacific and Western Hemisphere.”

Expeditionary Cutter Squadron forces will integrate with U.S. Combatant Commands to conduct exercises and maritime cooperative activities that enhance interoperability, strengthen strategic partnerships, and advance shared security objectives throughout the region.  The transition of the Expeditionary Cutter Squadron reflects the Coast Guard’s intent to provide agile, capable, and responsive maritime forces. These forces will rapidly support national security objectives across a range of operational theaters while leveraging the Service’s unique authorities.

This explains open-source images of the entire PATFORSWA force seen shipping past Singapore in March.

All six Bahrain-based USCG Sentinel-class cutters eastbound in the Singapore Straits – USCGC Charles Moulthrope (WPC-1141), USCGC Robert Goldman (WPC-1142), USCGC Glen Harris (WPC-1144), USCGC Emlen Tunnell (WPC-1145), USCGC John Scheuerman (WPC-1146) & USCGC Clarence Sutphin Jr. (WPC-1147) – March 2026 SRC: X-@StraitsSights

As well as Tunnnell and Moulthrope popping up in the Philippines a couple of weeks ago exercising with the locals in the South China Sea and during Cooperation Afloat Readiness and Training (CARAT) in Thailand last week.

The squadron is forward-deployed west of Guam, as noted by Janes:

“The cutters are approved to operate from Singapore and Subic Bay in the Philippines through September [2026], with command and logistics handled out of Singapore and vessels rotating through Subic Bay,” the spokesperson said. “These operations reflect a long-standing commitment to a free and open Pacific and support a region where all nations, large and small, can operate freely, safely, and lawfully at sea.”

Are they going to remain there or fall back to Guam?

Of note, the service already has three 154s currently based in Guam, replacing two aging Island-class WPBs. They have been conducting some seriously long-legged (like 5,380nm) patrols as of late.

So does this mean there will be nine 154s in Guam?

Likely not, but you could see these new-to-the-WestPac boats soon spread out across allied Operation Blue Pacific nation partners that have little-to-no maritime forces, such as the Cook Islands, the Federated States of Micronesia, Fiji, Kiribati, Nauru, Palau, Papua New Guinea, the Republic of the Marshall Islands, Samoa, Tonga, Tuvalu, and Vanuatu– most of which have very real problems with incroachng Chinese influence, smuggling and illegal fising.

Now, fast forward to this week, and news comes that a Hong Kong company intends to operate the turboprop-powered Catalina IIs with Pan American World Airways’ “Winged Globe” logo.

From Flight Global:

Catalina Aircraft Trust, the Florida holder of the original Catalina amphibious flying boat’s type certificate, has taken another step toward bringing a modernised turboprop-powered variant of the aircraft to market.

The company has secured a letter of intent from Hong Kong-based Pan American Airways System covering purchases of up to 46 of the planned NGAA “Next Generation Amphibious Aircraft” Catalina II.

Catalina Aircraft is now evaluating engines, avionics and other systems needed to develop the aircraft, which founder and president Lawrence Reece notes will be the only Western-certificated transport-category flying boat.

He envisions demand for up to 600 Catalina IIs of several configurations.

More here.

Of course, with Hong Kong officially part of Red China, whether they want to be or not, the prospect that these 46 shiny new flying boats could be used to shuttle around small detachments of PLAN naval infantry around the Nine-Dash Line is real.

Looks like the LSM concept may just happen after all…

The Damen LST 100 design, which was picked last December to be the Navy LSM– coming to a shipyard near you

TOTE Services in Jacksonville yesterday picked up a $2.6 billion contract from Naval Sea Systems Command’s PAE Maritime to serve as Vessel Construction Manager (VCM) for the McClung-class Medium Landing Ship (LSM) program, with the first hull to be delivered by 2029.

You know, the mini-LSTs that the Navy is building for the Marines to shuttle NMESIS missile batteries and light armor around the Western Pacific in a sea-denial-from-the-shore kind of philosophy, setting up what are now termed as a “Marine Corps fires expeditionary advanced base.”

A Navy Marine Expeditionary Ship Interdiction System launcher, a command and control vehicle, and a Joint Light Tactical Vehicle are transported by a U.S. Navy Landing Craft Air Cushion from Pacific Missile Range Facility Barking Sands, Hawaii, out to U.S.S. San Diego, Aug. 16, 2021. The movement demonstrated the mobility of a Marine Corps fires expeditionary advanced base, a core concept in the Marine Corps’ Force Design 2030 efforts. (U.S. Marine Corps photo by Cpl. Luke Cohen, released)

The contract will cover management of constructing the first eight LSMs, with a program of record for up to (hold your breath) 35 of the baby phibs built to the Damen LST 100 double-ended Ro/Ro design.

This thing:

Via Damen:

The LST100 is 100.68 metres (330 feet) long with a beam of 16 metres (52 feet) and a draught of 3.58 metres (12 feet). It is suited to a diverse range of operations. With its ability to transport personnel, vehicles, equipment and cargo, the vessel can be used in patrol, landing, survey and reconnaissance operations, as well as for the delivery of humanitarian aid & disaster relief.

In its standard design, it features bunks for 282 personnel. Cargo can be transported on the RoRo deck (500m2), vehicle deck (400m2) and on the helicopter deck. The vessel is able to sail at speeds of up to 14 knots, with an endurance of 3,890 nautical miles. At an endurance speed of 10 knots, it can reach up to 7,530 nautical miles.

The LST100 features extensive flexibility. Its modular design enables straightforward adaptation and upgrade without compromising the benefits of standardization. For example, with the addition of a standard, 20-metre modular block, the vessel can be enlarged to the LST120 design during construction.

Besides the intended purpose and general use as a ‘phib, the LSMs have an obvious use in Over The Horizon – Special Forces (OTH-SF) operations, stand-off Mine Counter Measures (MCM) operations support, and as a general helicopter/UAV “lilipad.”

Now, to be clear, TOTE is not actually going to build the LSMs, simply award and manage shipbuilder contracts- you know, something NAVSEA should be capable of doing, but in program after program has proven absolutely incapable of doing so. Looking at you, FFG and LCS programs.

Anyway, the award announcement, for the record:

TOTE Services LLC, Jacksonville, Florida, is awarded a $2,206,000,000 firm-fixed-price contract for vessel construction management services to award and manage shipbuilder subcontracts for the new construction of up to eight Medium Landing Ships. This contract includes options which, if exercised, would bring the cumulative value of this contract to $2,605,075,850. Work will be performed in Marinette, Wisconsin (65%); Houma, Louisiana (16%); Jacksonville, Florida (9%); and other locations (10%), and is expected to be completed by June 2030. If all options are exercised, work will continue through September 2031. Fiscal 2025 shipbuilding and conversion (Navy) funds in the amount of $1,933,941,000 (88%); and fiscal 2026 shipbuilding and conversion (Navy) funds in the amount of $272,059,000 (12%), will be obligated at time of award and will not expire at the end of the current fiscal year. This contract is awarded with funding from the One Big Beautiful Bill Act (Public Law 119-21) and directly supports the national effort to revitalize and rebuild American shipbuilding. This contract was competitively procured via the System for Award Management website (sam.gov), with one offer received. Naval Sea Systems Command, Washington, D.C., is the contracting activity (N00024-26-C-2421).

Warship Wednesday 1 July 2026: The Klinker Dinker

Above we see a great period Kodachrome of the well-armed Crosley-class high-speed transport USS Kleinsmith (APD-134) moored next to the Chicago Sun Times building in July 1959 during the celebration of the opening of the St. Lawrence Seaway.

Laid down in WWII as a destroyer escort but completed as a frogman delivery vehicle, she starred in an iconic movie released some 75 years ago this week on Uncle Sam’s “fin-footed, goggle-eyed, beach-blasting heroes,” before heading off to hold the line in the South China Sea for another 30 years.

The Crosley class

During the early days of WWII, with a dire need for small and fast amphibious warfare vessels, especially in the South Pacific, the Navy quickly converted 32 old flush-deck destroyers left over from the Great War.

Dubbed “Green Dragons,” such conversions meant landing their 4-inch guns, which went on to equip armed merchant ships, as well as their torpedo tubes. Also left behind were half of their boilers, which dropped their speed down to 25 knots. These high-speed transports (APDs) were given a trio of newer high-angle 3-inch/50 guns, one 40 mm AA gun, and five 20 mm AA guns, and the capability to carry up to 300 Marines or soldiers for a brief period. Where torpedo tubes once were, they now carried four 36-foot LCVP landing craft on large davits.

USS Colhoun (APD-2) February 1942. In her Green Dragon configuration 80-G-464374

These converted flush-deckers saw very hard service, with one three out of the four Dragons of TransDiv 12, USS Colhoun (DD-85/APD-2), Gregory (DD-82/APD-3), and Little (DD-79/APD-4), all lost in the Guadalcanal Campaign within a week of each other. The surviving fourth, USS McKean (DD-90/APD-5), was later sunk by a Japanese bomber.

With the concept of destroyer-sized transports vetted and with replacements needed, the Navy soon ordered 99 Buckley– and Rudderow-class destroyer escorts converted as APDs (though five were canceled).

Just under 1,800 tons and 306 feet long, the Rudderows were hardy 23-knot ships that would be classified as sloops or corvettes in other navies, but the term destroyer escort seemed a better fit for the USN and their pair of 5 inch /38 dual purpose mounts, four 40 mm Bofors, ten  20 mm single mount Oerlikons, torpedo tubes and depth charges allowed them to punch out of their weight class. Plus, they could float in just 11 feet of seawater, which meant they could get pretty close into old Hirohito’s backyard.

To maximize their usefulness, these ships were redesigned from the stack back, with the aft 5-incher and torpedo tubes never fitted. This left them with six Bofors in a 3×2 arrangement and six single 20mm mounts along with two stern racks for depth charges. Surface search radar (SA, SF, SL or SU) and a QGA sonar set were standard.

The first Rudderrow APD conversion was USS Crosley (APD-87, ex-DE226) which entered service in October 1944, the leader of what would become a 51-vessel class.

Drink in these images of Crosley-class member USS Joseph M. Auman (APD-117).

Auman carried UDT-7 to the Pacific in late 1945, then was laid up in 1946. In 1963, she was transferred to the Mexican Navy and served as ARM Tehuantupec (H05) until 1989

Their reason for existing was to carry a company-sized element of Marines, UDT teams, Army Rangers, etc., and bring them to the three-fathom line out from the surf, where landing craft would take over and do the rest of the job to get them over-the-beach.

To get their Marines in the water, the Crosleys had four 36-foot LCVP landing craft, each capable of holding 36 men in marching order, able to theoretically land 144 men in a single lift.

A 26-foot whale boat was shoe-horned in to serve as a gig/control vessel. Six 25-man floater nets and eight 25-man balsa wood floats provided emergency accommodations for 350 men should the APD have to be vacated in an emergency, and the boats were not available.

Ship’s crew included a skipper and 10 wardroom officers, 15 CPOs, and 164 crew, all with their own personal gear lockers. Less than luxurious accommodations were provided for 12 “greenside” officers and 150 enlisted, without the aforementioned lockers, as they were supposed to be short-term riders. Total berthing was for 346 souls (24 in officers’ country and 322 assorted enlisted), leaving only six to hot bunk if all the billets were full.

There was also a series of small storage compartments and allotted deck space, designed to carry six 1/4 ton trucks (jeep/GPW equivalent), two M-2-4 1 ton trucks, four ammunition carts, four 75mm M1 pack howitzers, 6,000 cu. ft. of ammo, 3,500 cu. ft. of general cargo (C-rats, etc.), as well as bunker space for 7,000 gallons of mo-gas. With no vehicle deck to speak of and her landing craft in davits, the only way to load these was via the crane on the stern once the Higgins boats were in the water.

Meet Kleinsmith

Our subject was named after Water Tender First Class Charles Kleinsmith (NSN: 2428775), a regular who enlisted in the Navy just after his 18th birthday in 1922. After service as an engineering rate on the battleships USS Wyoming (BB-32) and Maryland (BB-46), cruisers Milwaukee (CL-5), Cincinnati (CL-6), Portland (CA-33), and Honolulu (CL-48), and the carrier Saratoga (CV-3), he transferred to the new flattop Yorktown (CV-5) on Halloween 1940.

He earned a Navy Cross, the kind they give your family after, during the Battle of Midway aboard Yorktown, giving his last to fight a fire in Boiler Room No. 1 and assisted in keeping the boiler under steam to keep the ship’s auxiliary power in operation after a Japanese attack that “enabled the fighting carrier to attain the speed necessary for launching planes to oppose a Japanese aerial attack.” Lost in the battle, he is still listed as missing, presumed dead, promoted to Chief Water Tender, posthumously.

Watertender First Class Charles Kleinsmith

The 25th of the 37 destroyer escorts (Yard Nos. 266-303) ordered from the Defoe Shipbuilding Co of Bay City, Michigan, starting in October 1942, the future USS Kleinsmith was laid down as Defoe Hull No. 291 on 30 August 1944, a Rudderow-class destroyer escort (DE-718).

She was launched 27 January 1945, sponsored by Mrs. Mary Agnes Kleinsmith, Charles’s widow.

Note the fella holding on to the bow!

Towed down the Mississippi to New Orleans via the Illinois River and Lakes Michigan and Huron, she finished outfitting there and was commissioned as USS Crosley (APD-87), 12 June 1945, just before what would have been her namesake’s 41st birthday.

Her plankowner c/o was LCDR Alden James “Doc” Laborde (USNA 1938). It was the young Louisianan’s third command after being called back from the reserve list in 1942, having been skipper of USS PC-560 and USS Blair (DE 147) on Atlantic duty.

Of note, just two other tin cans were completed by Defoe past Kleinsmith, Hull 292 USS Weiss (DE 719/APD 135) and Hull 293 Carpellotti (DE 720/APD 136), with Hull Nos. 294-303 canceled by the Navy.

War!

Commissioned in the twilight period between VE-Day and VJ-Day, Kleinsmith’s war was short but she still served.

Leaving New Orleans for a shakedown cruise to Guantanamo Bay and post-shakedown availability at Norfolk, she departed the East Coast on 4 August 1945 for the Pacific via the Panama Canal. In post-war interviews with Laborde, he was advised the little APD would be used as a UDT ship for the Operation Olympic Landings in Southern Japan in November, but VJ-Day scrubbed that plan.

After calls at San Diego and Pearl Harbor, she reached Buckner Bay, Okinawa on 1 October and spent the next five months on Occupation duty in Japanese and Chinese waters with Task Group 59.2.

Leaving Sasebo on 21 February 1946, she arrived at San Francisco six weeks later with 118 returning veterans embarked.

With a one-page War History, her crew was eligible for the Navy Occupation Service Medal and China Service Medal (for period 28 September 1945 to 22 February 1946), but Kleinsmith did not rate any battle stars.

None of the 51 Crosley-class APDs were lost in the war, with 34 mothballed in gently used condition by 1947.

One of just 17 Crosleys retained on active duty post-war, Kleinsmith departed the West Coast on 10 April 1946 for the East Coast via the Panama Canal, arriving in Norfolk on 1 May, where she would call home for the rest of her U.S. Navy career.

The 1954 Jane’s entry for the 92 remaining DE-APD conversions still in the U.S. fleet, with the Crosleys (converted Rudderows) lumped in with the Lawrences (converted Buckleys). Most of the ships in both classes were in mothballs at this time:

Cold War

Operating with the UDT frogmen out of Little Creek and assorted East Coast Marine units, Kleinsmith spent the next 14 years on a series of exercises ranging from Puerto Rico (amphibious training at Vieques Island) to Maine (submarine shakedown support), with ship-to-shore, gunfire support, ASW, and antiaircraft drills alternating with seven very real deployments to the Mediterranean during an era where the Soviets were always over the horizon.

It was while in the Caribbean on one such exercise that Kleinsmith was tasked with what would be referred to these days as a Non-Combatant Evacuation Operation (NEO) on 24 October 1958 when she rescued 56 U.S. citizens and 3 foreign nationals at Nicaro, Cuba, where they were endangered by military operations ashore between Batista’s Army and Castro’s rebels.

In the summer of 1959 (27 May to 3 August), Kleinsmith became one of the few active duty U.S. warships in modern history to conduct an extended operation on the Great Lakes, transiting the newly opened St. Lawrence Seaway.

In doing so, she was the first naval vessel in several Lake ports in a century or more.

Movie Star

For three weeks in 1951 (15 January to 6 February) the old “Klinker Dinker” stood by at Naval Station Key West to serve as a floating movie set for the Richard Widmark vehicle, The Frogmen.

Highlighting the efforts of Navy UDT men during WWII, many of the extras on the “set” were real UDT men, brought down by Kleinsmith from Little Creek for the occasion, and the film shows some very realistic depictions of period tactics and methods used by these men.

Our little APD shows up in scene after scene.

The film was a major box-office success, ranking 37th among that year’s top earners.

Distributed by 20th Century Fox, it became a cultural phenomenon and is still widely recognized for bringing scuba diving and underwater action to mainstream audiences, clearing the way for a generation of follow-on “dive suit” movies and no doubt driving eager volunteers to The Teams for decades.

The film also enjoyed a wide overseas release.

Under a New Ensign

Several of the Crosleys that had been laid up in 1946 were held in mothballs for 15 years, then transferred aboard to overseas allies looking for a cheap-to-run escort with low mileage.

Crosley herself was stricken from the Naval Register on 1 June 1960, pulled from her rusty berth at Green Cove Springs, and transferred to Ecuador. Likewise, ex-USS Brock, Tollberg, and Ruchamkin were transferred to Colombia in the 1960s. Ex-USS Rednour went to Mexico in 1969 along with Auman. Four others went to South Korea.

In that vein, Kleinsmith was tapped in late 1959 for transfer to the Republic of China (Taiwan) under the Military Assistance Program.

To support the handover, in early 1960, the ROCN sent a 20-person team led by LCDR Chen Zhenmin to  San Diego or on-board training. Subsequently, her hybrid U.S./ROCN crew sailed the ship to Taiwan in March, arriving at Tsoying on 16 May for a combined decommissioning/handover/commissioning ceremony.

She was named ROCS Tien Shan, which translates to “Heavenly Mountain,” and given pennant APD-815. Assigned to the 212th Destroyer Squadron, she engaged in regular patrol and amphibious warfare exercises for the next seven years.

The 1960 Jane’s entry:

By 1967, the ROCN had seven active ex-USN APDs, all dubbed the Mountain class after Tien Shah (Kleinsmith).

Jane’s for that year:

Others left unclaimed in U.S. service were soon scrapped, while a handful were given an extension to continue to serve a few more years, reclassified as LPRs (amphibious transport, small).

In May 1967, Tien Shah (Kleinsmith) was sent on the fourth Dunmu (Goodwill) voyage under RADM Guo Xunjing. Carrying 4th year naval cadets, she steamed to South Korea, Guam, Okinawa, and the Philippines, returning in August. It was the longest and best-traveled of the ROCN’s Dunmu cruises at the time.

In December 1967, Tien Shah had her pennant changed to APD-215, and she was assigned to the amphibious fleet.

Before 1974, she and most of her sisters picked up a second 5″/38 Mk 12 mount on their stern, taken from a similarly modernized Fletcher-class destroyer which had been given other armament, as well as six 324mm ASW torpedo tubes.

As described in that year’s Jane’s:

She was also later given some modern AA defenses in the form of a RIM-72C Sea Chaparral launcher.

By April 1978, pushing 33 years old, Tien Shah was then reclassed as a patrol frigate (PF-615, later PF-815) and transferred to the 131st Fleet, a coastal defense force tasked with counter-smuggling and fisheries protection.

That saw her armament reduced to just her forward twin 40mm Bofors.

Late in her career as an OPV, with just her forward Bofors. 

She would soldier on for another 14 years, carrying pennant LPR-815 for most of that era, and still using the same checkerboard and seahorse crest as Kleinsmith, kept for good luck.

Via Baker, circa 1995 on the class:

Her final skipper passed on an extensive video in English to the APD Association/Kleinsmith Association in 1995 on the occasion of the tin can’s 50th anniversary reunion, including a walk-through of how the vessel looked at the time.

Decommissioned in October 1995 after 50 years of service, she was sold for scrap.

The ROCN ultimately operated 13 Mountain-class frigates/transports, and the last in service, ROCS Shou Shan (PF-837), the ex-Crosley-class USS Kline (APD-120), was put to pasture in May 1997. She was sunk as a target three years later.

Epilogue

Our subject had a remarkable 36 skippers, 25 of those Taiwanese.

Perhaps the most famous of Kleinsmith’s American captains was “Doc” Laborde, her plankowner wartime commander. After leaving the Navy, he designed and built the first submersible offshore drilling rig, Murphy Oil’s Mr. Charlie. He also founded ODECO, Tidewater Marine, Gulf Island Fabrication, and the Almar Foundation. A well-known mover and shaker in Gulf drilling for decades, Laborde passed in New Orleans in 2014, aged 98, and left behind five children, 18 grandchildren, and 35 great-grandchildren.

Tien Shah’s best-known skipper was ROCN VADM Lan Ningli, who has served as Deputy Chief of Staff of the Naval Headquarters, Commander of the 124th Naval Fleet, Director of the Intelligence Division of the General Staff Headquarters, Chief of Staff of the Naval Anti-Submarine Warfare Command, and Director of the Naval Headquarters Intelligence Agency. Retired in 2017 after 40 years of service, he is a noted wargamer and naval pundit.

Much of Kleinsmith’s 1950s logs are digitized in the National Archives.

Further, a quick YouTube search shows that The Frogmen is available to stream for free.

As for the APD/LPRs left on the U.S. Navy List, there were still at least 23 Buckley (Lawrence) and Crosley-class vessels still around in 1967, with some of the survivors given FRAM updates and others given limited conversions to serve as flagships.

Jane’s for that year, including a good list of disposals and transfers:

However, that would soon come to an end.

In November 1969, USS Beverly W. Reid (APD-119/LPR-119) was decommissioned and placed in reserve at Orange, where she remained inactive, for almost five years before her sale for scrap. She was the last Crosley in U.S. service.

Today, only one Crosley exists, the Colombian Navy’s ARC Cordoba (DT-15), formerly USS Ruchamkin (APD-89). Most of her has been serving as a museum ship at Jaime Duque Park since the 1980s.

The ROCN still conducts Dunmu goodwill training cruises, with the latest one seeing three ships crossing the Pacific Ocean and entering the Panama Canal and the Caribbean Sea, sailing 20,000 miles and calling at ports as diverse and far-flung (to Taiwan) as Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Belize, and Guatemala.

Decisively Samudravijaya, or, Starting a New Career at 58

The ex-USCGC Decisive (WMEC 629), a B-Type Reliance-class 210-foot gunboat/cutter, is now in active service as SLNS Samudravijaya (SLS P 628) in the Sri Lankan Navy. I guess SLS P 629 was already taken or something.

Note she now carries a twin Bofors 40mm L70 mount forward, an upgrade from the MK 38 25mm chain gun she carried for the past 30 years with the USCG, while, arguably, still short of the 3″/50 MK 22 Decisive, which she was commissioned with in 1968.

A simple ship with twin diesel engines and almost zero automation, she joins class member SLNS Samudura (P261)/ex-USCGC Courageous, which has been in service with the force since 2005, and two former 378-foot Hamilton-class cutters transferred in recent years, SLNS Gajabahu (P626)/ex-USCGC Sherman, and SLNS Vijayabahu (P627)/ex-USCGC Munro.

She self-deployed 14,775nm to her new home from the USCG Yard at Curtis Bay, ironically, where she was built in the 1960s.

Once upon a time, she was stationed at CGS Pascagoula, formerly NAVSTA Pascagoula, directly across from Ingalls on Singing River Island– where I was very familiar with the “Swamp Rats” and toured her for an article in Sea Classics before her final assignment to Pensacola in 2017.

A bit of Decisive remains on the Gulf Coast.

One of Decisive’s 26-foot Mark V Motor Surfboats (MSB), DEC1 is preserved as part of the USCG static display at the Battleship Alabama Park in Mobile.

This circa 1994 MSB MKV replaced one of Decisive’s original 1960s-era wooden-hulled 26-foot Monomoy surfboats and was used aboard while the cutter was stationed at Pascagoula. It was the go-to when having to conduct boardings or rescues in heavy seas.

Dubbed a “bathtub” for obvious reasons, these craft were self-righting and self-bailing. The MSB MKV was built by Ocean Technical Services in Harvey, Louisiana, and used a Cummings 4BT3.9M diesel to push it at 18 knots.

Typically manned by three, it could carry 10 passengers or 15 survivors in a pinch, depending on size.

The exhibit includes not only the surfboat but also a 41-foot UTM, a S-61/HUS-1G/HH-52A Seaguard (1371), and a S-55B/HO4S-2/HH-19G (1258), the latter two sourced from the National Museum of Naval Aviation to honor the nearby CG Aviation Training Center (ATC), which has trained the service’s pilots and aircrew since 1966.

Warship Wednesday 3 June 2026: The Mighty Mud Duck

USCG Historians Office

Above we see the 240-foot Tampa-class cruising cutter/gunboat USCGC Modoc (WPG-46) in her circa 1922-1940 peacetime white and buff livery, likely somewhere off North Carolina, her stomping grounds when not on ice patrol.

A hard-charger in an interesting class of cutters, Modoc had several brushes with history during her career and wartime service.

The Tampas

In late 1917, with 47 USCG cutters and 272 boat stations transferred to the Navy’s control under the mobilization plan for the American entry to the Great War, six of the smaller service’s largest cruising cutters on the East Coast– the 205-foot USCGC Algonquin and Manning, Seneca (204 feet), Ossipee (165 feet), Tampa (190 feet), and Yamacraw (191 feet)– had been quickly fitted with extra guns and depth charges and sent overseas to Gibraltar.

The 205-foot USCGC Seneca, among the largest and most capable cutters when the U.S. entered the Great War, spent 1917-19 overseas on convoy escort duty

The six-pack formed Patrol Squadron Two of the Atlantic Fleet Patrol Forces, Sixth Division, and were tasked with escort duties for convoys sailing between England and the Mediterranean. They gave yeoman service, with Tampa tragically lost during the conflict. Seneca alone escorted 30 convoys, accounting for an armada of more than 500 ships.

With that as a forward, on 12 November 1917, the Navy General Board met with USCG Constructor Frederick E. Hunnewell to discuss the smaller service’s future shipbuilding program. It had been decided that the service would begin construction on a new class of larger, more capable cutters. The guidelines favored a 240-foot vessel with decent warfighting characteristics (speed and armament) as well as endurance and seakeeping, with the Navy stressing a 16 knot speed (most of the cutters deployed to Europe pushed 12 knots, maximum) and Board member RADM Charles Badger (USNA 1873) urging “three 5-inch guns centerline, one 3-inch anti-aircraft gun, and two machine guns” as standard armament.

With magazine space for 200 rounds per 5-incher, a 6,000-gallon-per-day evaporator, a five-kilowatt radio, day and night signaling apparatus, a submarine signal receiver, two 30-inch searchlights, an ice machine, and six 30-foot small boats, the estimated cost of six desired new 240-foot cutters so armed would be $700,000 apiece, with the class pushing $4.2 million and change.

However, with the Navy prioritizing its own vessels for construction during the war, the planned half-dozen 240-footers never made it to the schedule before the Coast Guard reverted to the Treasury Department in 1919 upon the outbreak of peace.

Still a program of record, the service whittled the number of hulls down from six to four and pursued novel cost-savings measures and innovations to cover the basics of the circa 1917 mandate, but on a more shoestring T-department budget.

In 1921, Captain Quincy B. Newman, Engineer-in-Chief of the Coast Guard, introduced the first synchro-turbo electric drive on ships in any of the U.S. services on the class leader of the new 240-footers, the USCGC Tampa (WPG-48). The plant consisted of two Babcock & Wilcox, cross-drum type, 200 psi, 750° F superheated boilers transferring to a General Electric 2,040 kVa electric motor driven by a turbogenerator, pushing a single 13-foot four-bladed screw.

At the time, they were the largest and most capable cutters ever to enter service.

A more in-depth dive by Newman, from Marine Engineering and Shipping Age, January 1922:

On trials, Tampa made 16.2 knots against a planned 16. Effective range was 5,500nm at 9 knots, about what a plodding convoy was good for.

Here’s a better look at the plan of these 240s. Note the forward “officers’ country” for the eight members of her wardroom. The berthing for the 81 enlisted was over the engineering spaces.

Robert Scheina notes that:

“The 240-foot cutters followed the traditional cutter hull form, having a plumb bow and counter stern. These features proved particularly undesirable while on the International Ice Patrol. Heavy seas coming up under the counter caused severe shocks. The wardroom in this class was well forward; thus, the deck sloped upward. This feature was known as the ‘Honeywell Hill,’ in honor of the principal architect of the class.

Armament in peacetime would be two unshielded 5″/51 Mark 8 single mounts (new guns for the Coast Guard, only entering Navy service in 1911), a 3/50″ DP gun, a pair of 57mm 6-pounders (loved by the Coast Guard for “shots across the bow”), and a 1-pounder saluting gun. Weight and space were reserved on deck for multiple depth charge racks, while the 6-pounders could be swapped out with additional 3″/50s in time of war.

When it came to peacetime, the typical magazine allowance was 100 5-inch Service rounds, 100 3-inch Service, 110 6-pounder Service, 60 1-pounder Target, and 110 6-pounder Blank charges. Also stored were 20 Torpedo “D” wrecking mines with another 20 TNT booster charges. This went out the window in wartime.

Likewise, with the Coast Guard long keeping the ability to send up to half of a cutter’s 89-man complement ashore to suppress assorted rowdies, bandits, and pirates, as needed, the class had an allowance of 53 “Landing Force Kits” each consisting of a M1903 Springfield rifle with bayonet, scabbard, and belt; a canteen with cup and cover, a haversack, and canvas leggings. For good measure, 25 M1911 pistols with belts and magazines were also included. Other goodies in the small arms locker included two Lewis guns, a single Thompson sub gun, two 22LR rifles and two .22LR pistols for marksmanship training; two .45-70 black powder line throwers, and four 1-inch Very pistols.

Landings, boardings, recoveries, and rescues were accomplished by eight boats: a 27-foot whaleboat, two 26-foot Monomoy surf boats, a 26-foot sailing launch, a 26-foot self-bailing surfboat, a 22-foot motor dinghy, and an 18-foot punt.

All four of the class (Tampa, Haida, Mojave, and Modoc, all named for Native tribes) were built by the short-lived Union Construction Company of Oakland, with Tampa laid down on 27 September 1920 and the last, Modoc, delivered on 14 January 1922.

Meet Modoc

Ordered in 1920 with the rest of her four-member class, the future Modoc was Yard No. 19. Launched  1 October 1921 with a bottle of sparkling cider smashed by a Miss Jean Lemard, Modoc commissioned 14 January 1922.

After completion, she headed via the Panama Canal to join sisters Tampa and Mojave on the East Coast while Haida remained on the West. Modoc’s first homeport was Wilmington, North Carolina, where she augmented and then replaced the old (circa 1899) 188-foot USCGC Seminole, with the latter eventually shuffled off to semi-retirement in the Great Lakes.

She is well remembered in Wilmington, which she called home for much of the next 18 years. She was captured by local photographer Louis T. Moore in her typical dock in front of the Customs House.

In the Ice

During the April-to-June ice season, when bergs from Greenland calve and drift south into the North Atlantic shipping lanes, Modoc, Tampa, and Mojave alternated 15-day stints on the International Ice Patrol, a service founded just after the loss of the Titanic.

Forward based out of either Boston or Halifax (it changed throughout the decade), these cutters tracked, day by day, the icebergs and field ice, determining their set and drift, then duly reporting their presence and location to the hydrographic office of the Navy while broadcasting the data by radio for protection of shipping. Each season in the 1920s typically tracked 400 large bergs.

It was customary for the cutter on station during the anniversary of the great liner’s loss to hold a ceremony. The skipper read prayers, three volleys were fired, and taps were sounded by the ship’s bugler. One such service aboard Modoc in 1925 was filmed and remains in public archives.

Lifesaver

While not on Ice Patrol, Modoc performed the standard counter-smuggling, derelict destruction, law enforcement, and SAR that you would expect from a Coast Guard cutter.

She participated in several peacetime “saves.”

In February 1923, Modoc was sent from Wilmington to the lumber schooner Friendship, reported sinking in Oregon Inlet, about 90 miles south of Virginia Beach, and effected a rescue.

In January 1924, she rushed to the site of the Danish freighter Normania, reported foundered off Norfolk, but the steamer’s crew had already been rescued by the closer SS Henry R. Mallory just before their vessel plunged to Davy Jones.

In December 1926, Modoc responded to the sinking of the Coast Guard schooner Lincoln, which was destroyed by fire with a loss of six lives, several miles southwest of Cape Lookout Lightship. Lincoln, a seized rumrunner, was being used to carry oil and gasoline to lightships and stations.

In October 1926, Modoc responded to the de-masted schooner Purnell T. White, which had been caught in the northeaster off Cape Lookout and towed her to port.

January 1928 saw her tow the disabled motor yacht Cutty Sark, owned by Alexander Smith of Chicago and New York, into Charleston.

In January 1929, three barges loaded with lumber from Fernandina, Florida, to Georgetown, South Carolina, broke away from their tug in a storm, and one, the barge Belfast, foundered off Frying Pan Shoals, with Modoc saving her four-man crew.

March 1930 saw Modoc involved in the sweeping search for the missing yawl Nahma, owned by Mr. A. Felix Du Pont, with 12 souls, including his 19-year-old son Richard, aboard. They eventually turned up, but Nahma, Richard, again at the wheel, was lost off Cape Hatteras just two years later, the six aboard rescued by the Army transport Republic. Richard Chichester du Pont would meet his end in 1943, piloting an experimental glider at March Field in California, aged just 32, with a commercial carrier he had founded beforehand, now today’s American Airlines.

In February 1936, Modoc was sent to the aid of the 7,200-barrel Atlantic Refining Company tanker Albert Hill, bound from Philadelphia to Atreco, Texas, for a cargo, 200 miles off the coast of South Carolina. Soon after taking her under tow, the 435-foot Hill suffered an explosion, with the cutter rescuing all but four of her crew. Nonetheless, Hill was pulled into port and eventually returned to service after extensive repair at Robins Dry Dock in New York and was only scrapped in 1947.

In July 1936, Modoc was sent to search for the schooner Dewless, which started that summer’s biennial 635-mile Newport-to-Bermuda race and then promptly vanished. Dewless, owned and skippered by F. William Schnirring of New York, was located safe and sound two days later.

While on the Ice Patrol, in May 1930, the cutter documented an encounter with a white whale.

(49629216003)

Not War, but You Can See It from Here…

When the Germans invaded Poland on 1 September 1939, Modoc was steaming off the Virginia Capes, conducting small arms gunnery drills. Ordered to put into Norfolk with leaves canceled and those detached recalled, she soon transferred 24 enlisted, nearly a third of her complement, to bring the large 327-foot USCGC Bibb up to a more warlike footing. The bigger cutter was soon bound for duty with the newly formed U.S. Neutrality Patrol in the North Atlantic.

Even with a reduced crew, Modoc soon was on patrol herself, trailing and identifying passing vessels offshore, exemplified by this entry from 15 November 1939, in the Atlantic.

This continued through 1940, with a break at the Coast Guard Yard in Curtis Bay for a quick refit, and patrols as far south as the Caribbean and Gulf of Mexico.

Modoc began New Year’s 1941 on patrol in the Florida Straits and in early February, she responded to the distressed 2,512-ton Brazilian freighter SS Mahukona, which disappeared without a trace while sailing from Newport News to Rio.

By April, Modoc was in drydock at Algiers across from New Orleans, prepping for continued North Atlantic service, calling at her traditional home port of Wilmington by the end of the month. Sent from there to the Boston Navy Yard for weapon upgrades, including adding two water-cooled .50 cal machine guns, two depth charge racks and two Y-gun projectors to her stern, she steamed out of Beantown for the Gulf of Maine on 12 May 1941, beginning a North Atlantic patrol off Newfoundland two days later, in doing so relieving cutter Northland (WPG-49), whose mission was to patrol the convoy lanes and pick up survivors of merchantmen sunk by German U-boats.

On the afternoon of Saturday, 24 May 1941, the neutral USCGC Modoc was shadowing British Convoy HX-126 on the lookout for survivors of nine freighters and tankers sunk by Wolfpack West over 20-22 March. Her radiomen overheard British traffic concerning the sinking of the vaunted battlecruiser HMS Hood, sent to the bottom of the Denmark Strait with 1,400 of her crew by the battleship Bismarck that morning.

Soon enough, Modoc’s lookouts reported a mysterious man-of-war on the horizon, followed by a biplane, and three other warships in the distance. It turned out the first ship was Bismarck, the aircraft was a Swordfish torpedo plane from the carrier HMS Victorious, and the three trailing ships were the battleship HMS Prince of Wales and the cruisers Suffolk and Norfolk.

Managing to avoid fire from either side, Modoc was able to observe the Sword’s attack on the German battleship and the resulting flak, then slipped back into the mists as the faster ships sped on for their rendezvous with destiny.

Her deck log from that evening:

Still in her peacetime white and buff scheme, the British reportedly thought she was a yacht at first, then almost opened fire on her.

Coast Guard Cutter Modoc (WPC-46) and the German battleship Bismarck by James Flood https://www.jamesaflood.com/uss-modoc-cg-wpg-46/

Following this exciting patrol, Modoc reported for duty with the Navy on 1 June 1941 and was designated flagship of the South Greenland Patrol, serving in the waters of that frozen subcontinent through the rest of the year.

As noted by DANFS:

Transferred to the Navy by Executive Order No. 8929 of 1 November 1941, Modoc joined the Greenland Patrol, whose orders were to do “a little of everything.” This duty involved keeping convoy routes open, breaking and finding leads in ice for the Greenland convoys, escorting the convoys and rescuing survivors from torpedoed ships, constructing and maintaining aids to navigation, and reporting weather conditions. Ships of the patrol were also expected to discover and destroy enemy weather and radio stations in Greenland, continue hydrographic surveys, maintain communications, deliver supplies, and conduct search and rescue operations. All these duties, the Coast Guard performed with exemplary fortitude and faithfulness throughout the war.

War!

With the U.S. officially in the war after Germany declared war on it on 11 December 1941, following Pearl Harbor, Modoc was in Greenland’s waters. Sent back to Norfolk for six weeks of repairs and alterations in early 1942, she returned to Greenland on 26 April, escorting the oiler USS Laramie (AO-16), the latter filled with a vital cargo of gasoline and oil for Army bases on the island.

In May, she escorted the empty Laramie, SS Omaha, and SS Azra back to Boston. Then came subsequent convoy runs from Newfoundland to Greenland and back for the rest of the year, often working with sisters Tampa and Mohawk.

The Ice Patrol suspended during the war; on 19 March 1943, the massive 14,795-ton whale factory ship Svend Foyn collided with an iceberg 70 miles south of Cape Farewell while sailing with Convoy HX-229A from New York to Liverpool with a cargo of fuel oil. The vessel foundered two days later with the loss of 43 out of the 195 crew and passengers aboard, with the USCGCs Aivik, Algonquin, and Frederick Lee on scene, later joined by Modoc to transfer those plucked from the sea to the latter cutter for transport to St. Johns.

It was an epic rescue.

As related by DANFS

Due to the deep roll of the Modoc, operating without lights in the middle of the night, the taking on of the half-frozen survivors was a difficult feat. Several of her crew distinguished themselves by going down the net and working waist-deep in the icy water to haul half-numb survivors aboard. One man, Leonard W. Campbell (101-707) CBM, almost lost his life in this rescue work. He and two others–John T. Hendrix (200-373) CEM, and William F. Coultas (251-300) Sea1c, were commended, and each of them later received the Navy and Marine Corps Medal. The Svend Foyne finally sank with 24 persons reported trapped aft. When the vessel sank, the Modoc and Algonquin searched the position and heard cries for help, but could not sight any survivors. Nearly four hours later, she took aboard one man who died of heart failure an hour later due to the extreme cold of the water in which he had been immersed for hours.

Modoc steamed into St. Johns with 128 living men from Svend Foyne on 28 March 1943.

Returning to convoy work for the rest of 1943, Modoc joined the CGCs Storis and Comanche in a futile search for survivors of the lost USAT Nevada, which had gone missing in a storm off Greenland on 16 December.

During a stateside refit in 1944, Modoc landed her 5-inchers, Y-gun depth charge throwers, and .50 cals, kept her 3″/50s, added four 20mm Oerlikons, as well as 4 K-gun throwers and two forward Mousetrap ASW devices. She also picked up SF-1 and SC-3 radars and a QCJ-3 sonar. Not bad, given the circumstances.

Modoc, along with the cutters Tampa and Algonquin, spent part of March and April 1945 as ASW cats in the waters off Portland, Maine, chasing the “tame mouse” Italian submarine Goffredo Mameli (T.V. Cesare Buldrini) in exercises.

Remaining a fixture on the Greenland convoy routes the rest of the war, Modoc went to the assistance of the distressed HMT Strathella in February 1944, the steamer Chippewa in November 1945, and RMS Begun in December 1945.

Modoc returned to the Treasury Department in accordance with Executive Order No. 9666 of 28 December 1945.

Modoc 1944-45

She earned one battle star for her WWII service.

But she still had at least one more good sub-arctic rescue in her.

Damaged by heavy seas, the EC2-S-C1 type Liberty ship SS Henry Baldwin, carrying 589 troops, radioed for help (“Developed plate crack in starboard of after-deck. Extremely heavy westerly seas”) on 16 January 1946 from a position about 300 miles southeast of Cape Race, Newfoundland. Modoc, sailing back to the U.S., was ordered at once to her aid, and Baldwin limped into Argentia. After repairs, the freighter continued service for another 24 years.

Afterward, Modoc reported to Boston Navy Yard on 26 January for installation of weather equipment and repairs.

On 26 March 1946, Modoc inaugurated the first post-war International Ice Patrol, using radar and LORAN for the first time in the IIP’s history. Also, for the first time, patrol aircraft were used to assist the cutter– USCG PBY-5As and PB4Y-1s of VP-6CG out of Argentia.

Decommissioned 1 February 1947, just shy of 25 years of service, ex-Modoc was sold to Manuel Velliantis in Honduras.

She was converted for merchant use as a barco bananero (banana boat) and renamed Amalia V. Later registered in Ecuador in 1950 by Tropical Navigation Co., she was renamed Machala, and served as a merchantman until scrapped in 1964

Epilogue

Little exists of the Modoc outside of her logbooks and plans in the National Archives and the occasional relic on the collector market.

The Coast Guard recycled the name Modoc for use on the transferred WWII-era USS Bagaduce (ATA-194), which served as USCGC Modoc (WATA-194/WMEC-194) from 1959 to 1979. That 143-foot vessel saw an active post-military career, serving as a bed and breakfast and as a sea base with the Earthrace Conservation group.

Since the International Ice Patrol has been maintained by the Coast Guard, there has been no berg-related loss of life in the area during the annual season, which now typically counts. The last cutter patrol was by USCGC Spar in 1990, the mission transitioning to aircraft and, by 2016, a combination of aerial and satellite surveillance.

Warship Wednesday 20 May 2026: Long Night of the Wolf

Naval History and Heritage Command NH 85868

Above we see the modified Spica (Alcyone)-class torpedo boat Lupo at sea during maneuvers likely at the “H” naval review off Naples on 5 May 1938. Note her “LU” hull identifier, 3.9″/47 OTO M1937 forward, and four 17.7-inch torpedo tubes aft.

Lupo had a short career– as did most of her assorted three dozen sisters– but she was exceptionally well-fought (or lucky, depending on the outlook) some 85 years ago this week.

The Spicas

The Italian navy was huge, and I mean huge, fans of torpedo boats.

Going back to the 80-foot Thornycroft-built Nibbio and Yarrow-built Avvoltoio in 1881, they had already built and discarded more than 60 Aldebaran and Euterpe class boats before the Great War began.

In the early 1920s, the fleet had almost 100 newer torpedo boats on hand (Condore, Pellicano, Gabbiano, four Sirio class, 18 Perseo class, four Oriones, 38 1PN-class, 39 40PN-class) that went 200~ tons, were good for 25-27 knots, and carried a few 350mm or 450mm tubes with a couple of light guns.

Italian torpedo boat 54 AS during World War I. She was one of 39 40PN-class boats built during the war. At 150 tons, they ran 139 feet oal, could make 27 knots, and carried two 76mm guns, two 450 TT, and had space for 10 mines.

That’s not even counting the 422 small 20-30 ton mosquito boats of the MAS (Motoscafo Armato Silurante) type that were ordered during the Great War, of which 244 were completed.

As we said, the Italians really liked torpedo boats. I mean, if you look at the Italian coastline and consider the short ranges involved in fighting in the Adriatic and chokepoints such as the Strait of Messina and Strait of Bonifacio, it makes perfect sense.

Fast forward to the late-1920s/early 1930s and, with Italy’s 100 Great War vintage large torpedo boats slow, poorly armed, and aging, the Italian admiralty moved to replace them with a new class of faster (34 knots) boats that were much better armed (three 3.9-inch guns, four Vickers 40mm AAA guns, four 450mm tubes, as many as 28 mines).

To allow the weight and space for needed engines (two sets of Tosi geared steam turbines and two Yarrow boilers generating 19,000hp, good for 37 knots) and extra armament, this new class of TBs would come in just under 600 tons (on paper) to take full advantage of the London Naval Conference of the 1930s minimum tonnage threshold for regulated warships.

This left a fairly large 269-foot hull with a layout similar to a downsized Italian Freccia class destroyer (1,200 tons, 315 feet oal, 44,000hp). When compared to other navies, these ships would be more akin to destroyer escorts or frigates, only faster and without the ocean-crossing range, the latter a feature that the Italians didn’t need.

The Italian Freccia-class light (1,200 ton) destroyer Saetta, probably at the 5 May 1938 fleet review off Naples. The Spicas could be seen as essentially just downsized Freccias at 45 feet shorter and half the weight.

Main gun armament was three OTO 100/47 Mod. 1931 guns in single mounts, backed up by a AAA battery of eight 13.2 mm machine guns in four twin Breda Mod. 31 mounts.

Torpedo armament was four 17.7-inch tubes arranged either in a twin turnstile with a single tube on each side of the bow, as in class-leader Spica, or in four single tubes, two on each side of the bow, as in the Vega and her flight.

See below from Jane’s 1938 edition:

Jane’s 1938 entry. Disregard the mention of 37mm guns. Only Spica and Astore had two twin 40/39 Vickers-Ternis. None had 37s. The typical pre-war AAA mounting was M.31 Breda mounts with twin 13.2mm guns. These were later replaced by twin Breda 20/65 Mod. 1935 and then by four single Scotti-Isotta-Fraschini 20/70 Mod. 1939 mounts.

They also had weight and space reserved for two depth charge throwers, although they had no listening gear, at least pre-war.

When it came to mines, they could both mechanically sweep (with embarked cables and paravanes) and lay mines (able to carry up to 28) if needed.

Named for constellations, the first two of the class, Spica and the Astore, both built in the Bacini & Scali Napoletani (BSN) yard between 1933-35, were sold to Sweden in 1940 and commissioned as the destroyers (jagaren) Romulus and Remus, respectively, serving that Scandinavian Navy until 1958.

The next 30 were built in three flights (16 “Alcyone” type, 6 “Climene” type, and 8 “Perseus” type) with very minor variations in armament. Besides BSN, which built four more vessels, CT Riva Trigoso built two (Canopo and Cassiopea), CNR Ancona built four, Ansaldo Genoa built 12, and CNQ Fiume 6, all entering service by November 1938.

Meet Lupo

Lupo was one of a dozen of the Spicas built by CNQ (Cantieri navali del Quarnaro S.A.) in Fiume in spitting distance of the old Whitehead torpedo factory with her direct sisters Libra (LB), Lince (LC), and Lira (LR), all having the same armament and arrangement.

Late model boats, they suffered a bit from mission creep and had grown to 785 tons standard, 1,035 full load, on a hull some six feet longer than the original Spica design but with the same engineering plant. This dropped the maximum speed down to just over 30 knots, a big difference from the blistering 37 that Spica got in light load on trials.

To be sure, by this stage, they were more DE than TB.

Jane’s 1938 entry putting Lupo and the rest of the “L” boats built by CNQ as part of the 16 Alcyone/Alcione type vessels listed as Partenope type.

Laid down 7 December 1936, Lupo launched 7 November 1937, and commissioned 20 February 1938, under the command of LCDR (capitano di corvetta) Pio Valdambrini, based in Sicily.

War!

By the time Italy entered WWII on the side of the Axis during the Fall of France, Lupo and sisters Lince, Libra, and Lira, were part of the VIII Torpedo Squadron (Squadriglia torpediniere) based at Torpediniere Rhodes in the Aegean Naval Command.

Beginning the war under the command of LCDR Gennaro Cioppa, by December 1940, Lupo’s skipper was 37-year-old LCDR Francesco Maria Mimbelli. A Livorno-born regular from a Dalmatian family who put on his cadet uniform at age 15, by 1923, he was serving as a junior officer on the gunboats Caboto and Carlotto on China Station. Part of the Italian delegation sent to the London Naval Conference, he later served on the cruiser Trento and commanded torpedo boats during the 1939 invasion of Albania.

Lupo drew her first blood at 18:00 on 31 January 1941 when, taking part in a patrol of the Caso Channel in the Dodecanese with sister Lince, spotted part of British Convoy AN.14 and went in to attack. Headed from Alexandria to Piraeus, the small (Aegean Northward) convoy element had two merchantmen escorted by the light cruiser HMS Calcutta and two corvettes.

With Lince pulling away Calcutta with a torpedo attack that failed, Lupo went after the largest merchie, the big Shell tanker Desmoulea (8,120 GRT), and hit her with two fish (the British say one), badly damaging the vessel. Abandoned by her crew in a sinking condition, the tanker was later towed the next day to Suda Bay with her cargo intact.

Notably, along with torpedo damage inflicted on the cargo ship Clan Cumming (7,264 GRT) of Convoy AS.10 on 19 January by the Adua-class submarine Neghelli (NG), Lupo’s hit(s) on Desmoulea were the only Italian naval successes against British convoys in the Aegean.

Lupo and her sisters were soon pressed into service shuttling troops around the Greek littoral.

On 25 February, she and Lince, along with the old destroyers Crispi and Quintino Sella, carried a reinforcement force of 240 soldiers and 88 marines to the embattled islet of Castelrosso (Kastellorizo​) in the Levantine Sea, which was being assaulted by British 50ME Commandos in the rather slapstick Operation Abstention. This led to a swirling night action between the two TBs and the British destroyers HMS Hereward and Decoy, with no casualties on either side. Finally able to land their troops on the 27th, Lupo and Lince also turned their 3.9-inch guns on said Commandos (reportedly causing three deaths and seven wounded), which withdrew the next day.

This brings us to the…

Night of the Wolf

As part of the epic German airborne assault on Crete, while Kurt Student’s Fallschirmjäger made their last ride-of-the-Valkyries level jump to glory in Operation Merkur, a two-pronged seaborne assault was attempted by the mountain troops of Julius Ringel’s 5. Gebirgs-Division.

One of these convoys of mountain troops was made up of 21 overloaded requisitioned Greek caiques, coasters, and barges, carrying 2,331 men, which left Piraeus on 19 May, bound for Maleme on the Allied-held Greek island at a lumbering seven knots. A second, larger, flotilla of 42 vessels would carry 4,000 mountain troops to Heraklion.

Both convoys were surveilled by RAF reconnaissance aircraft and duly reported.

The smaller Gebirgsjäger convoy was escorted at first by the Spica-class torpedo boat Sirio, but had to be replaced as she lost her starboard propeller. Her intended replacement, the old de-rated destroyer Curtatone, was sunk by mines on 20 May.

This left Lupo to answer the call alone.

Assigned to the defenseless convoy of wallowing caiques, she arrived on scene on the 21st of May and by that night made contact with British RADM Irvine Glennie’s Force D north of Canea, still 18 miles from their intended landing beaches at Maleme.

First involved was the destroyer HMS Janus, which Lupo fired two torps at from 1,000m at 2233.

Then came another vessel looming out of the night, the cruiser HMS Dido, which got a third and fourth torp fired at her from 700m at 2235.

Then came a second cruiser, HMS Orion, which she avoided ramming by just a few feet.

A third, the legendary HMS Ajax of Graf Spee fame, was on scene, as were the destroyers Hereward, Hasty, and Kimberley.

There was no way one Italian torpedo boat could compete with that kinda pressure, especially when the Brits had radar on their side. Just counting the cruisers, Lupo had three 3.9-inch guns against the British cruiser’s 10 5.25-inch and 16 6-inch guns. Then add the 20 4.7-inch guns on the four British greyhounds.

Lupo broke contact, and the Brits were able to sink 10 caiques in the night, sending over 300 German troops to the bottom of the Med, decimating the III Battalion of the 100th Gebirgsjäger regiment. Two caiques, altogether loaded with 113 Germans, made it to shore on Crete at Cape Spatha. The other caiques were able to slip away in the confusion and made it back to Piraeus.

Lupo during the Battle of Crete convoy action

The second, larger, convoy was recalled to prevent a similar fate.

The only damage done to the RN was via friendly fire, with Orion suffering 11 casualties due to 40mm (2-pounder) hits (which Lupo didn’t carry). The Brits also fired a tremendous amount of ammunition in the clash, with the cruisers firing some two-thirds of their magazines (Orion had 38 percent of her shells left, Ajax 42 percent, and Dido just 30 percent). Further, Ajax rammed and sank a troop-carrying barge, damaging her bow in the process, her stem fractured and bent over waterline level, and her forepeak flooded.

Lupo had been hit at least 18 times by 6-inch and 4.7-inch shells from British destroyers and cruisers, although most of the AP rounds passed cleanly through her without exploding. She suffered two dead, quartermaster Orazio Indelicato and gunner Nicolò Moccole, and 26 wounded. This against a complement of 116 officers and men. She nonetheless returned to the scene of the convoy massacre at dawn on the 22nd to pick up survivors, with Lupo, seaplanes, and rescue launches picking up 242 waterlogged Gebs by 1600 that afternoon.

The 5th Gebirgs-Division reported 506 missing in the Crete campaign, with most having drowned with the caiques, delivered to Posiedon by Force D.

German assault on Crete – May 1941 via USMA collection

Most of the Gebs involved in Operation Merkur that arrived on Crete did so as fly-in reinforcement, with 5,000 brought by Junkers 52s.

As for Lupo, she sailed back into Taranto looking like Swiss cheese.

The clash saw Mimbelli awarded the Gold Medal of Military Valour, while Lupo had the Silver Medal placed on her ensign.

Continued campaigning

Repaired and refitted, Lupo picked up a more ASW-oriented battery to include landing her 13.2mm guns for four twin Breda 20/65 Mod. 1935s, and taking on hydrophones and as many as 40 depth charges, with many of her sisters so converted.

Thus rearmed, the Spicas became a fixture on Italian convoys in the Med, supplying outposts in occupied Greece and running troops to North Africa.

Italian torpedo boat Lupo and hospital ship Gradisca Tobruk, Libya, on 28 May 1941

While escorting a convoy of four steamers with the torpedo boats Altair and Monzambano and the auxiliary cruiser Barletta on the evening of 19 October 1941, Altair struck a mine laid eleven days earlier by the British submarine Rorqual in the Gulf of Athens, and her sister Lupo came to her aid. Taking 124 men aboard from Altair, Lupo tried to tow the vessel, whose bow had been blown off, but had to cut ties and let the stricken TB sink.

On 23/24 November 1941, Lupo and sistership Cassiopea, while escorting two German steamers, Maritza and Procida, to Benghazi with supplies for Rommel, bumped into British Force K, which had been birddogged to the convoy by deciphered Ultra messages. This pitted the two Italian TBs against the light cruisers HMS Aurora and Penelope and the destroyers HMS Lance and Lively. The resulting night action in the rain left the two German steamers sunk, but the Italians survived to fight again. Lupo is generally credited with hitting Penelope’s superstructure with her 3.9s, causing minor damage, and in turn, picking up some minor damage herself.

Lupo was with another convoy, from Piraeus to escort to Suda, again with sister Cassiopea, escorting three merchies when they escaped an attack from HM Submarine Porpoise on 17 January 1942.

In March 1942, the now-famous Mimbelli was sent to command the IV MAS Flotilla operating in the Black Sea, leaving Lupo in the hands of her third wartime skipper, LCDR Giuseppe Folli.

Committed to a series of Piraeus to Tobruk convoy runs, it was on one of these sorties on 2 September 1942 that Lupo’s convoy came under the combined attack of USAAF B-24s and HM Submarine Thrasher.

On her next run to Tobruk, with sister Sirio and three small freighters, Lupo survived an attack from HM Submarine Taku.

The extremely lucky Lupo’s run ended on the evening of 2 December 1942 when, along with the TBs Ardito, Aretusa, and Sagittario, she was escorting three steamers from Naples to Tripoli. After dodging Albacore bombers of NAS 828 out of Malta, which struck the steamer Veloce, the convoy again found its old nemesis, Force K, this time composed of the radar-equipped destroyers HMS Jervis, Nubian, Kelvin, and Javelin.

Lupo, at the time attempting to tow Veloce and bathed in the light of 40-inch searchlights, was smothered in 4.7-inch shells at 2,000 yards, and sank in the Gulf of Gabès at 2345.

Lupo carried LCDR Folli and 134 other souls to the bottom of the sea. Just 29 survivors were picked up by Ardito.

The shattered wreck of the ship, missing her bow and stern, was found approximately 96 miles SW of Lampedusa and 20 miles off the Kerkennah Islands in December 2011 by AHTS Buccaneer, some 435 feet down. It has been extensively surveyed.

Epilogue

The Italians recycled the name “Lupo” for Battaglione Lupo, a marine infantry unit within the infamous Xª Flottiglia MAS in 1944. It fought with Mussolini’s rump Italian Social Republic in Northern Italy against Allied forces and partisans until the end of the war.

Lupo Battalion Italian Marines of X MAS division, La Spezia, Italy, 1944. Note the “samurai” mag carriers and MAB 38 Beretta SMGs.

The modern Italian Navy commissioned a frigate (F 564) using the Lupo name in 1977, which served until 2003. She is still in service with Peru as BAP Palacios (FM-56).

Of Lupo’s 30 Spica-class sisters in Italian service, 23 were lost during the war. Seven survivors returned to Italian service, modernized as fast corvettes outfitted with radar, sonar, and Hedgehog ASW devices. The last two, Sagittario and Libra, were only retired in 1964.

As for Lupo’s only victim during the war, the Greenock-built Shell D-class tanker Desmoulea was patched up, survived a second torpedoing in May from an Italian S.79 bomber, was patched up again, survived German He. 111s, and continued sailing until 1961. A tough-to-kill tanker for sure!

Lupo’s most famous skipper, LCDR Mimbelli, earned two Iron Crosses (EK1 and EK2) for the Sevastopol campaign and picked up two companion Silver Medals and five Bronze to his Gold for leading several actions with his speedy MAS boats along the Calabrian and Sicilian coasts. Post-war, he commanded the battleship Vittorio Veneto and the cruiser Garibaldi before heading the Naval Academy in Livorno.

The Italian fleet’s CNO from September 1959 to April 1961, Ammiraglio di Squadra Francesco Maria Mimbelli, moved to the retired list in 1964 and passed in 1978, having spent 57 of his 72 years in uniform.

As noted by the Marina Militare, “The mission report of the Royal Torpedo Boat Lupo, written by Commander Mimbelli in a dry and elegant style, is kept by the Historical Office of the Navy in Rome, for current and future generations.”

In 1993, an Ammiragli-class destroyer, ITS Mimbelli (D 561), was commissioned with his name and remains in service.

NOAA: USV Powerhouse?

NOAA’s Office of Coast Survey (OCS) is currently utilizing fully uncrewed contract USVs for an offshore hydrographic survey mission along the Florida Gulf Coast.

Operated by Woolpert, the mission is being conducted by Chance Maritime’s Chance MC29 and larger MC40 platforms.

The Chance MC40

Chance MC40

Over the multi-month project, Woolpert will survey approximately 11,000 linear nautical miles. Woolpert hydrographers, positioned across multiple time zones, will remotely conduct hydrographic surveys around the clock. Survey data is uploaded to a cloud server via Starlink satellite communications, where it is ingested into Woolpert’s Automatic Survey Production Environment (ASPEN) and made ready for further postprocessing by Woolpert’s hydrographic processing team.

In an expansion of the concept, NOAA just awarded Chance a $21.6 million contract for up to eight Chance LR30 platforms, equipping NOAA with a fleet of long-endurance USVs purpose-built for hydrographic and fisheries surveys.

Coupled with what the USCG is doing with Saildrones, this is all some very good vetting of programs with some serious 21st-century military applications, without which Big Navy can surely piggyback off of.

I hope people are paying attention.

Jetting around the Baltic littoral

Aurora 26 just wrapped up in the Baltic, with 18,000 soldiers from 13 countries participating in the Swedish-led NATO exercise. It notably included some Ukrainian drone operators to serve as, among other things, a very capable and modern OPFOR.

Images released by the Swedes are stirring, highlighting two battalions (2.amfibiebataljonen and 5.amfibiebataljonen) of the Swedish Navy’s Amphibious Corps, are great.

They also include shots of a couple of massed CB90 (Stridsbåt 90H) waves, with each of the highly maneuverable 52-foot shallow-draft (31 inches) jet boats capable of toting 20 troops at 40 knots.

Sure, they would usually move in much smaller groups, at night, but the photo op is amazing, and sends a bit of a point.
