Destroyer Escort vs German torpedo, 2025 edition

Norwegian Oslo-class frigate Trondheim (F302), in 2004, back when she was having a much better day

Recently, during exercise Ægir 25 in September 2025, the Norwegian Ula (U-Boot-Klasse 210) class submarine KNM Uthaug (S304) fired one of its Atlas Elektronik DM2A3 Seehecht torpedoes at the decommissioned Oslo (Dealey) class frigate ex-KNM Trondheim (pennant number F302), intending to sink the battered target vessel off the coast of Andøy in Andfjorden.

The 2,100-ton Trondheim, decommissioned in 2007, had already been the target of Naval Strike Missiles launched by the frigates HMS Somerset and KNM Thor Heyerdahl as well as previous NSM tests in 2013.

As noted by NATO, “The purpose of the shot was to verify and demonstrate the striking power that the weapon and the submarine represent. A submarine has long endurance, operates covertly, and has a unique ability to dictate the battle.”

NATO Allied Joint Force Command released the video on 17 November 2025, and it really shows you why you don’t want to be on the receiving end of a 576-pound torpedo warhead.

Warship Wednesday 5 November 2025: Celebrate the Ram!

IWM (FL 22661)

Above we see the modified former Brazilian J-class (RN Havant-class) escort destroyer HMS Harvester (H 19) underway during World War II in coastal waters, complete with Western Approaches style disruptive camouflage scheme. True to her name, she was a harvester of men in peril, saving nearly 2,300 men directly from the beaches of Northwestern France and another 244 adrift the sea.

She was also a harvester of steel sharks.

Over the course of no less than 51 North Atlantic convoy runs, she bagged at least two Axis submarines, one of them notably some 85 years ago this week.

The Brazilian Hs

The British Royal Navy would order some 27 assorted “G”, “H” and “I” Class destroyers between 1934 and 1936 as part of the rearmament to safeguard against the growing German, Italian, and Japanese fleets in the uneasy peace leading up to WWII. They were slight ships, of just 1,800 tons and 323 feet overall length with a narrow 33-foot beam, giving them a dagger-like 1:10 length-to-beam ratio. With a speed of 35 knots and a 5,000 nm range at half that, they could keep up with the fleet or operate independently and had long enough legs for North Atlantic convoy work, should such a thing ever be needed in the future.

The differences between the three classes were primarily in engineering fit, minor superstructure changes, and armament. They were typically fitted with a quartet of QF 4.7-inch (120 mm) Mk IX guns, a few AAA mounts, between 8 and 10 anti-ship torpedo tubes, and depth charges for ASW work.

HMS Grenade (H86), a G-class destroyer. Note her layout, which was like all her sisters. Grenade would be sunk in May 1940 off Dunkirk by German Stukas.

The 27th and last of the type delivered to the RN from the ships the Admiralty ordered was HMS Ivanhoe (D16) on 24 August 1937, completing the classes built out in just four years, which is not bad for peacetime production.

The G/H/Is would prove so successful of a design that the British exported it, accepting prewar orders for 19 ships for overseas allies: Argentina (seven Buenos Aires class ships delivered in 1938), Greece (two Georgios class delivered in 1939), Turkey (four desperately needed Inconstant class delivered in 1942, largely to keep Istanbul friendly at a crucial time in the war) and a half-dozen Jurua-class tin cans for the Brazilian Navy.

The Brazilian Navy in early 1938 ordered six modified H-class destroyers, spread across the Vickers, White, and Thornycroft yards. They would be named Jurua, Javary, Jutahy, Juruena, Jaguaribe, and Japura after rivers and towns in Brazil. Construction proceeded along nicely, and all were christened with their intended names by visiting dignitaries from the Latin American country and afloat in the summer of 1939.

Then, with the war in Europe, London made a deal to purchase the six nearly complete Juruas from Rio while they were still fitting out in a deal that would include providing assistance and plans for Brazil to build another six H-class destroyers domestically at the government’s Ilha das Cobras shipyard.

Rather than a fit for four 4.7-inch guns, these six former Brazilian destroyers in British service would carry only three, with the extra deck space freed up to be used for more depth charges– capable of toting as many as 110 ash cans across three rails and eight throwers.

They would enter service between December 1939 and June 1940 as the Havant class (Havant, Handy/Harvester, Havelock, Hearty/Hesperus, Highlander, and Hurricane), keeping with the “H” class naming sequence.

Hesperus is underway at sea, resplendent in her war paint. IWM A 7101

Meet Harvester (aka Handy, aka Jurua)

Ordered from Vickers by the Brazilian government on 6 December 1937 as the future destroyer Jurua, our subject was laid down at the company’s Barrow yard on 3 June 1938 alongside her sister, the planned future Japura. Jurua and Japura were purchased by the British government on 5 September 1939 while still on the builder’s ways and were launched into the water of the Irish Sea 24 days later to complete fitting out for Royal Navy service.

Our Jurua would initially be referred to as the future HMS Handy, while Japura would become HMS Hurricane.

One thing led to another, and Jurua/Handy would be commissioned on 23 May 1940, at the height of the Battle for France, as HMS Harvester, while Hurricane would only break out the white duster and join the fleet on 21 June 1940, well into the Fall of France.

Harvester leaving Barrow, June 1940

Speaking of which…

Dunkirk, et al

Without even the benefit of a proper shakedown cruise, the brand new Harvester, under LCDR Mark Thornton, RN, who had previously commanded the older S-class destroyer HMS Scimitar (H 21) on convoy defense, was rushed to the English Channel to help pull the BEF and Allied soldiers from France.

Harvester took part not only in the famous Operation Dynamo, doing her part with so many others to evacuate 338,226 Allied troops from the beaches and surf line of Dunkirk, but also in the lesser-known Operations Cycle (evacuation of 3,400 Allied troops from Le Havre) and Aerial (191,870 from a range of French Atlantic ports in late June).

She did this in the face of fierce German air and submarine attack, with her sister HMS Havant crippled by Luftwaffe aircraft during the Dunkirk operation, and was scuttled to prevent capture.

One of the former Brazilian RN H-class destroyers at Dover during the Dunkirk evacuation, crowded with Tommies on her deck. This ship is either HMS Harvester or Havant, both of which were active in Dynamo, the latter lost in the process. IWM H1668

The details of Harvester’s evac runs:

  • 29 May, Dunkirk (Op Dynamo), 272 men saved
  • 31 May, Dunkirk (Op Dynamo), 1,341 men saved (two round trips)
  • 9 June, Le Harve (Op Cycle), no troops found
  • 11 June, Saint-Valery-en-Caux (Op Aerial), 78 men saved

She also escorted transports during Aerial, who were evacuating Saint-Nazaire and St. Jean de Luz further down the coastline, and rode shotgun with the cruiser HMS Cumberland on a mission to bombard German positions on the occupied French coast.

It was reported that Harvester suffered at least one strafing from German aircraft and successfully evaded at least two torpedoes. LCDR Thornton, who had cut his teeth as a mid in the 1920s on the Jutland veteran battlewagon HMS Emperor of India, was mentioned in dispatches for his efforts.

The U-boat war

Harvester’s first of many convoy runs was to sanitize the area south of Ireland to clear the way for Halifax-to-Liverpool-bound Convoy HX 054, along with the destroyers HMS Highlander (a sister) and Punjabi on 16 June.

Her next run began on 29 June 1940 at Liverpool, riding shotgun with the inaugural “Winston Special,” Convoy WS.1, which carried some 10,000 British troops aboard the fast liners turned troopships Queen Mary, Mauretania, and Aquitania, to the Middle East. She also made the follow-on WS.2 and WS. 3A.

Then came ASW clearing for outbound Liverpool to Halifax return Convoys OB 194 and OB 199 in August, Liverpool to Gibraltar Convoy OG.43, Liverpool to Suez Convoy AP.3/1, and Freetown to Liverpool SL/MKS.47 in September; escorting inbound Sydney to Liverpool SC.8 in October, and screening OB.252 in November. It was on the latter that Harvester and the Canadian destroyer HMCS Ottawa came across the Italian Marcello class submarine Comandante Faà di Bruno (FB, I.5) on the afternoon of 6 November and likely sank the same, with all hands.

LCDR Thornton received a DSO on 12 January 1941 for the destruction of the enemy submarine and would remain aboard until March 1942, when he shipped out for command of the destroyer HMS Petard. Thornton was replaced by CDR Harold Pitcairn Henderson, RN, and CDR Arthur Andre Tait, DSO, RN, in turn. Of note, Tait had earned his DSO in 1942 while skipper of HMS Hesperus for sinking German U-boat U-93.

As for Harvester, the convoy runs continued, including five further OB runs, another OG run, at least seven outbound Liverpool to NYC/Boston ON convoys, four more SCs, two additional SL/MKS convoys, four Halifax to Clyde TC convoys, and seven more HXs.

She even had a brush with history, escorting HMS Prince of Wales along with sisters Havelock and Hesperus in August 1941 during the battleship’s passage to Newfoundland with Winston Churchill aboard for the Atlantic Charter meeting.

Besides dropping ash cans on contacts, she also saved the lives of those cast to the mercy of the sea. This included 90 survivors from the lost armed merchant cruiser HMS Dunvegan Castle during SL-43, 19 survivors from the British freighter Silverpine on OB.252, and 131 survivors from the ocean boarding vessel HMS Crispin on OB-280.

It was hard, dirty, and unsung work.

The famed American photojournalist Robert Capa, while crossing the Atlantic to North Africa with an eastbound convoy in 1941, caught two striking Kodachrome images of Harvester zipping among her charges, a seagoing greyhound stalking Axis sharks.

On 11 March 1943, while escorting convoy HX-228 west of Ireland, Harvester with LCDR Taite in command and the Free French Flower-class corvette Aconit in support, came across the Type VIIC boat U-444 (Oblt. Albert Langfeld) of Wolfpack Westmark and gave the new boat a hard fight.

In the end, after forcing U-444 to the surface, Taite chose to ram the German at 27 knots and send her back down, leaving 41 dead and 4 survivors to be plucked from the water.

Tragically, with the now-damaged Harvester dead in the water with a snapped shaft, she was twice torpedoed and sunk by U-432 (Kptlt. Hermann Eckhardt), which was in turn brought to the surface by Aconit’s depth charges and finally destroyed by gunfire and ramming. The Admiralty later passed on an order to halt ramming as a tactic after this incident.

The damaged Aconit then picked up five survivors from U-444, 12 from U-432, 12 survivors from the lost American Liberty ship SS William C. Gorgas, and 60 men from Harvester. Among those claimed by the sea were all three skippers from the lost warships, Taite, Eckhardt, and Langfeld.

Three days later, Aconti sailed into Greenock and discharged her motley accumulation of waterlogged sailors from three countries.

“Fighting French corvette sinks two U-boats. 14 March 1943, Greenock, the Fighting French corvette Aconit sank two U-boats by gunfire and ramming while escorting an Atlantic convoy through a U-boat pack on 10 March 1943. The second submarine had just torpedoed the British destroyer HMS Harvester. The Aconit steamed to a British port with survivors from the Harvester and a merchantman, and prisoners from the two U-boats.” IWM (A 15075)

“Survivors of the British Destroyer HMS Harvester fraternizing with the crew of FFS Aconit after the French corvette had avenged them by sinking two U-boats. The survivors are wearing the Aconit’s badge, and the cat is one of the Aconit’s three mascots – two cats and a dog.” IWM (A 15084)

Epilogue

Little remains of Harvester. I cannot even find where her wreck has been located. She no doubt rests very near the shattered U-432 and U-444.

She is best remembered in scale models and box art.

As for her first skipper, Mark Thornton chalked up assists on two additional submarine kill assists while in command of Petard, picking up a DSC, and was on the Combined Operations staff for Overlord. He then returned to destroyer operations post-war and retired as a full commander in 1956. He passed in London in 1982, aged 75.

Only three of the Brazilian destroyers survived the war, sisters Havelock, Hesperus, and Highlander, and were scrapped by 1947.

While the British have not reused the name Harvester, three French warships have since been named Aconit, including the modern La Fayette-class stealth frigate Aconit (F 713). The fourth Aconit flies the Free French jack, and its crew wears twin fouragères as a salute to the old corvette.

Mardi 04 janvier 2022, le capitaine de vaisseau Guillaume Fontarensky, adjoint organique de l’amiral commandant la force d’action navale (ALFAN) de Toulon, fait reconnaître le capitaine de frégate Jean-Bertrand Guyon comme nouveau commandant de la frégate de type Lafayette (FLF) Aconit.

Marine Experimental Recon, Narco Boats Break Cover during UNITAS

Looking back over the huge photo dump from the recent UNITAS 2025 exercise– which has been trucking along annually since 1960– a somewhat composite view arises of the Marine’s new Maritime Reconnaissance Companies (MRC), and the drone supply boats it looks to use to supply its pair of expeditionary Marine Littoral Regiments in forward, likely isolated, islands in the Western Pacific.

present to you the carbon-fiber hulled Whiskey Bravo boat in operation, utilizing a tire-clad, retired USCG 87-foot Marine Protector-class patrol boat as the target for a training VBSS team. In Marine use, the 40-foot Australian-built Whiskey Bravo is referred to as the more official Multi-Mission Reconnaissance Craft, or MMRC.

The Whiskey Bravo accommodates up to six operators seated on shock-absorbing seats and two crew members at the forward control console.

It can carry twin 4-round Rafael (Lockheed) Spike NLOS canister launchers on the stern (17nm range and a Mini-Typhoon remote-controlled stabilized .50 cal up front.

Without the armament, it can carry as many as 17 combat-loaded troops for short stints. The boat can be rushed to a forward area via C-17 and is air-droppable. Further, the WB can be optionally manned, controlled instead via remote datalink.

A take on how it could be employed.

As described in a November 2024 Proceedings piece by Lt.Col Brian Lusczynski, three active and perhaps one reserve Maritime Reconnaissance Companies will be established, each with 18 Whiskey Bravo boats (MMRCs) and 12 unnamed USV types.

Within a Marine division, the MRC will fall under a parent O-5 command such as the future mobile reconnaissance battalions (which are replacing the light armored reconnaissance units). Each MRC will consist of a headquarters element and three maneuver platoons operating MMRCs and USVs. Each platoon will comprise a headquarters element and three maneuver sections, with each section consisting of two MMRCs and two USVs.

Next, we have the Autonomous Low-Profile Vessel, or ALPV, which takes the nearly awash “narco sub” concept long used to run all sorts of contraband and options it for remote use to carry supplies to calm little lagoons right under the eyes of the PLAN.

It has been tested out by the Logistics Battalions of the Marine Littoral Regiments, and is described as “a semi-submersible autonomous logistics delivery system that has the ability to deliver multiple variations of supplies and equipment through contested maritime terrain.”

And a recent view of the cargo capability of the 65-foot ALPV, which seems to have several pallet-sized cargo holds.

The concept of getting some diesel, a few pallets of MREs and water, plus extra batteries and an assortment of lickies and chewies, shipped quietly into a forward atoll, could be a realistic way to keep isolated garrisons fed and semi-happy.

The ALPV is an autonomous logistics delivery system that the Marine Corps is testing to resupply a dispersed lethal fighting force discreetly and allow those operating in the littorals to be more sustainable, resilient, and survivable, both in competition and in conflict.

Meanwhile, the 16-foot Blacksea GARC was also seen sporting around during UNITAS.

It seems like it’s all coming together.

The (Not So) Silent (all the Time) Service

Happy National Shuffleboard Day (tomorrow).

Via the archives of the U.S. Naval Submarine School at Groton comes this little nugget:

The ballistic missile submarine USS Theodore Roosevelt (SSBN-600) had a shuffleboard mounted on a torpedo rack so that the crew could play tournaments. If the sub was ever in a situation in which the rack was needed, the CO said he was prepared to fire the shuffleboard out of the tube.
A George Washington-class FBM rushed into service during the Cold War to curb the “missile gap,” using components initially assembled for the Skipjack-class nuclear attack submarine USS Scamp (SSN-588), SSGN-600 was laid down on 20 May 1958 by the Mare Island Naval Shipyard; named Theodore Roosevelt and redesignated SSBN-600 on 6 November 1958; launched on 3 October 1959; sponsored by Mrs. Alice Roosevelt Longworth– TR’s then 75-year-old daughter– and commissioned on 13 February 1961.

U.S. Navy Launches Third Polaris Submarine. U.S. Navy’s Third Fleet Ballistic Missile Submarine Theodore Roosevelt (SSBN 600) is shown during launching ceremonies at Mare Island Naval Shipyard, Vallejo, California, on 3 October 1959. She is designed to fire Polaris missiles surfaced or submerged. The nuclear-powered vessel is 380 feet long and has a submerged displacement of 6,700 tons. Mrs. Alice Roosevelt, daughter of President Theodore Roosevelt, christened the boat named for her father. The photograph was released on 8 October 1959. (9/30/2014).

She was the first FBM to transit the Panama Canal and stood out of Charleston on her first deterrent patrol on 19 July, just five months after commissioning. After 46 patrols, on 1 December 1979, she became the first FBM to offload her A-3 Missiles at the newly built Explosives Handling Wharf at Bangor and was decommissioned on 28 February 1981. Her Final dismantling and recycling were completed in 1995.

Australia Goes $1.12B Hard in the Remote Minisub Paint

Palmer Luckey’s California-based Anduril Industries has developed its Ghost Shark XLAUV (Extra-Large Autonomous Underwater Vehicle) autonomous submarine from rough draft to finished product in three years.

Scalable, it can be anywhere from 20 feet to 98 feet oal with the sweet spot being the 39-ish foot variant, with a square cross-section that can carry and deploy “dozens” of Copperhead-100 class UUVs (or Copperhead-100M loitering munitions) and “multiple” Copperhead-500 class UUVs (or Copperhead-500M loitering munitions), also developed by Anduril.

The Australian government spent A$140M on the program in 2022, and Anduril has invested another $60M in a “sophisticated, robotic XL-AUV manufacturing facility in Australia, where employees are at work to produce entirely sovereign autonomous maritime platforms.”

Now, the Australian MoD has announced an A$1.7B (US$1.12B) Program of Record to deliver a fleet of Ghost Sharks, with production already underway. The five-year contract will support around 120 existing jobs and create more than 150 new jobs at Anduril Australia.

As noted by the company:

The reason for the magnitude of risk-taking in this enterprise is clear: the Ghost Shark’s entry into full-rate production marks the start of a new era of seapower through maritime autonomy. For years, Australia has faced the persistent and threatening presence of Chinese naval assets in its home waters. Ghost Shark is the instantiation of a Program of Record for AUVs that can directly address this challenge through coastal defense patrols and area-wide domain awareness powered by artificial intelligence at scale. Success in this effort would be a landmark opportunity to demonstrate the potential of autonomous seapower to address clear and urgent national security problems.

Ghost Shark can fit inside a 40-foot shipping container, which in turn can fly out on a C-17 or similar. The RAAF flew a prototype to Hawaii for last year’s RIMPAC.

The following is from Anduril on how the Copperhead/Ghost Shark combo can draw a “line in the sea,” so to speak.

Sea denial, 21st Century style.

The last shots in the foggy, frozen Kuriles, 80 years ago this week

While the sweeping battle between the shell of the once mighty Japanese Kwantung Army in Manchuria and Korea, reduced to some 600,000 second-rate troops, and the 1.5 million strong Soviet Far East Command, had officially ended on 16 August after just nine days of fighting, the Reds nonetheless kept pushing to seize territory right up to 2 September, meeting isolated pockets of resistance.

Meanwhile, in the Kurile Islands, a line of 56 volcanic islands stretching from north of Japanese Hokkaido, the northernmost of Japan’s home islands, to just off the tip of the Soviet Kamchatka peninsula, was still very much in play after 16 August.

The battle for the Japanese island of Shumshu, just six miles south of Kamchatka’s Cape Lopatka, raged for a solid week, 18 to 23 August, and cost the Soviets somewhere in the region of 1,500 casualties (exceeding Japanese casualties by a ratio of 3:2) while five of the Soviet’s 16 Lend Leased LCI(L)s used for the landings were lost along with the minesweeper T-152 and torpedo boat TK-565.

Landing on the Kuril Islands. Artist A.I. Dense, 1948 year

Japanese Lt. Gen. Tsutsumi Fusaki arriving at the Soviet line to negotiate the surrender of his forces in the Northern Kuriles, 22 August 1945. He led 12,227 remaining men of his 91st Division into captivity. He was released to Japan in 1946 and died in his hometown of Kofu in 1959.

Likewise, starting on 11 August, 100,000 Soviet troops swept past the Karafuto line, which had divided the island of Sakhalin into a Russian north and Japanese south since 1905. This began a straight-line ground campaign– sped up by leapfrog amphibious landings, bypassing strong points– that swept up the 20,000 Japanese defenders by 25 August.

Soviet soldiers from the landing force and the minesweeper T-589 (USN type YMS, ex USS YMS-237) in the port of Maoka, Sakhalin. Late August 1945.

In the meantime, on 16 August, Stalin proposed to Truman that, in addition to seizing all of the Kurile Islands, his forces should also occupy northern Hokkaido along a line from Kushiro to Rumoi.

Truman pushed back, saying that Hokkaido would surrender to MacArthur, but that an American base in the future Russian Kuriles sounded like a good idea.

Stalin backed down on the 23rd (the day Shumshu finally fell, showing the Soviets just how hard amphibious warfare against Japanese defenders could be) and said he would stay out of Hokkaido, but that the Americans would not be welcome to a base in the Kuriles.

In the background of this, at least three small Russian Series XI/XIII-Leninist, or L class, submarines and two squadrons of torpedo-carrying Ilyushin Il-4 (DB-3T) twin-engine bombers from Petropavlovsk were running amok off the North coasts of Hokkaido and around Sakhalin.

A Soviet Leninist, or L class, submarine. Smallish (1,400 tons, 273 feet oal) minelaying boats reverse engineered from the raised HMS L55, which sank in the Baltic in 1919, 13 of the type were built and operated by the Soviet Pacific Fleet

The DB-3T, with a suspended 45-36 AV (high-altitude) or 45-36AN (low-altitude) torpedo, looked ungainly because it was ungainly, with a cruising speed hovering around 180 knots with both of its knock-off Gnome-Rhone 14K radial engines glowing. It nonetheless could be effective in the right circumstances and would remain in Soviet/Warsaw Pact use long enough into the 1950s to gain the NATO reporting name “Bob.” Alternatively, it could carry MAV-1 or AMG-type aircraft mines.

They bagged at least eight Japanese ships in the last part of August, even though the IJN Admiralty had passed word that there was a general ceasefire and the rest of the Western Allies had paused offensive operations. Notably, all were sunk outside of the general Kuriles area.

  • Cargo ship Daito Maru No. 49 sunk by an unknown submarine on 22 August
  • Cable layer Ogasawara Maru (2,774 tons) sunk by L-12 (Capt. Shelgancev) on 22 August
  • Coaster Taito Maru (880 tons) sunk by L-12 on 22 August
  • Cargo ship Notoro Maru (1229 grt) sunk by aircraft on 22 August
  • Coaster Sapporo Maru No. 11 sunk by submarine, likely L-19 (Capt. Kononenko), on 22 August
  • Freighter Tetsugo Maru (1403 grt) sunk by L-19 on 23 August
  • Sub chaser Giso Maru No. 40 GO (273 grt) sunk in a surface action on 24 August
  • Sub chaser CHa-77 sunk by aircraft of unknown origin on 28 August

Ogasawara Maru was perhaps the saddest of these. Built for the Japanese Ministry of Communications in 1905 and capable of 10 knots, the cable layer left Wakkanai on Sakhalin Island on the afternoon of 21 August, carrying 702 evacuees– elderly people, children, and women ordered off the island by the military government– headed to Funakawa.

She never made it, with L-12 sinking her in the predawn of the 22nd while three miles off Mashike, littering the coastline for miles with bodies. Only 62 survivors were recovered.

Likewise, Taito Maru, on the same evacuation route, went down with another 667 souls.

A ninth ship, attacked but not sunk, was the 5,886-ton freighter turned minelayer Shinko Maru No. 2 (former Toyo Kaiun, 2577grt). Crowded with some 3,600 civilians evacuating from Otomari on Sakhalin, she left alone on the night of 20-21 August heading for Otaru Port at a speed of 9 knots. Around 0500 on 22 August, she caught a torpedo in her No. 2 hold and replied with her 12cm and 25mm guns in a surface action in the predawn against an unidentified submarine, which broke contact.

Brushing off a further attack by a torpedo-carrying plane once the sun came up that morning, she limped into Rumoi Port in Hokkaido with 298 bodies aboard and at least 100 known missing.

While Shinko Maru No. 2 was eventually repaired and, returning to commercial service, was still around as late as 1992, her likely attacker, L-19, disappeared on or around 24 August near the La Perouse Strait, thought to have either sunk from damage incurred in the battle or lost to a Japanese minefield (which ironically may have been laid by Shinko Maru No. 2). Her broken hull and the 64 crewmen were the Red fleet’s final loss of WWII.

L-12 returned to Petropavlovsk to honors, having logged two attacks and fired six torpedoes. Converted to a training hulk in 1959, the Russians only retired her fully in 1983.

Sistership L-18 (Capt. Tsvetko) was underway in late August in the area and landed 61 marines and three 45mm guns at Maoka (now Kholmsk), in the then Japanese-held south Sakhalin, the latter secured behind the fence constructed on the rear of the conning tower. She did not document any attacks on shipping. Tsvetkov was awarded the Order of the Red Banner and would later retire as an admiral.

Today, the Japanese government considers the three refugee-packed emergency evacuation ships (Ogasawara Maru, Shinko Maru No. 2, and Taito Maru) to have been attacked post-ceasefire by submarines and aircraft of “kokuseki fumei” (“unknown nationality”), and numerous memorials dot Hokkaido to those vulnerable civilians lost on the ships.

Meanwhile, no Japanese government has recognized the Russian sovereignty over four of the southernmost Kurile Islands (Kunashiri, Etorofu, Shikotan, and Habomai) occupied in 1945, and only marked the end of the state of war between the Soviet Union and Japan in 1956.

Welcome back, Whiskey

The future USS Wisconsin (SSBN 827) had her keel laid yesterday on her hull number date (8/27) at General Dynamics Electric Boat in Groton.

It looked like a beautiful day.

She is the second of 12 planned Columbia-class boomers, the long-awaited replacements for the Cold War leftover Ohio-class, the youngest of which is 28 years young.

She is the third Navy warship to carry the name of the 30th state after the famous, Iowa-class fast battleship USS Wisconsin (BB-64), which decommissioned in 1991 and stricken from the Naval Vessel Register in 2006, and the Illinois-class USS Wisconsin (Battleship # 9) of Great White Fleet fame.

As SSBNs are the battleships of today, the name makes sense.

Wisconsin likely won’t be delivered until 2032 or so, but with an expected 42-year service life, including 124 deterrent patrols, she will possibly outlive us all.

Final WWII VC Holder Boards his PBY for Home

Flying Officer John Alexander Cruickshank (126700), Royal Air Force Volunteer Reserve, late of No. 210 Squadron, has passed at the age of 105.

Born in Aberdeen in 1920, he joined the Territorials in Scotland at age 19. Once the war started, he served in the Royal Artillery until his transfer to the RAFVR came through in the summer of 1941. Following flight training in Canada, he joined 210 Squadron, piloting PBY Catalinas out of windswept RAF Sullom Voe in Shetland on ASW duties in the North Atlantic.

It was while supporting Operation Mascot, one of the myriad attempts to sink the Tirpitz in her Norwegian lair, 17 July 1944, that Cruickshank’s PBY, JV928 Y, encountered German type VIIC submarine U-361 (Kptlt. Hans Seidel) west of the Lofoten Islands.

The first bombing run, through fierce AAA fire from the surfaced U-boat, riddled the PBY but failed as the bombs did not release. This required an even more dangerous second run, lacking the element of surprise.

The swirling battle sent U-361 to the bottom of the Norwegian Sea, with Seidel and all 51 hands.

As for the PBY, JV928 Y suffered one crewman killed (Flying Officer J.C. Dickson, navigator/bombardier) and four more wounded, Cruickshank among them. Despite being hit by shrapnel in 72 places, including twice in the lungs and ten serious wounds in the legs, Cruickshank somehow refused morphia and remained in the cockpit beside the co-pilot until his damaged aircraft, full of dead and dying, made it some five hours back to the Shetlands and landed safely.

He earned Coastal Command’s third Victoria Cross, the others being posthumous.

Post-war, he left the service and went into banking. In 2020, he became the first VC holder to reach the age of 100, setting a new bar.

Rube Goldberg Torpedo, Balikpapan edition

Some 80 years ago this week.

Balikpapan, Borneo, then part of the newly liberated Dutch East Indies.

Unlike the six types/classes of Japanese Kaiten manned suicide torpedoes, the below seems more akin to the Kriegsmarine’s “Neger” attack craft, which amounted to an awash delivery torpedo carrying a coxswain instead of a warhead while a live G7e was clamped below it, albeit much more ersatz in nature.

Original historic wartime caption: “The Japanese 21-inch controlled torpedo. Usual procedure of the 21″ was as follows: Torpedos were stored in shelter; placed on rails launched into sea; wooden super-structure visible on torpedo was tied on with rope; operator rode torpedo within a striking distance of target; armed torpedo utilizing a rope; dropped axe on ropes binding super-structure torpedo and was cast free. 10 August 1945. (Two torpedoes were found, but there was no evidence of them ever being used in the area.)”

Tigershark on the move!

Here we see a great image of the Dutch Zwaardvisch class submarine Hr.Ms. Tijgerhaai (S 812) in West Indies waters, 1957, with the good Prof. Vening Meinesz and his team on board, conducting gravity research using special equipment during the voyage.

Laid down at Vickers in 1943 as the future Third Group T-class submarine HMS Tarn (P326), she was instead transferred before commissioning and entered Dutch service on 28 March 1945.

After working up out of Holy Loch with several of her British sisters, Tijgerhaai left Scotland some 80 years ago this week, on 5 August 1945, bound for Fremantle, Australia under the command of LTZS1c (LCDR) Arie van Altena, RNN(R), to get into the Pacific War.

Of course, the war would end while Tijgerhaai was en route to fight the Japanese, and she would, instead, clock in for the next five years off the coast of the Dutch East Indies to combat weapon smugglers and insurgents during the Politionele Acties in the colony that led to Indonesian independence.

She retired from Dutch service in 1964 following a nearly 20-year career and was sold for scrap.
