Warship Wednesday 7 January 2026: Wilbur’s Beachcombing

Official U.S. Navy Photograph, now in the collections of the National Archives. Catalog #: 80-G-432570

Above we see the modified Flower (Honesty) class frigate Prasae of the Royal Thai Navy aground behind enemy lines on the Korean east coast, some 75 years ago this week, in January 1951. Several U.N. personnel are standing on the beach near a boat, surveying the near-hopeless situation. An LCVP is also stranded just inshore of the frigate. Note ice on the shore and on the seaward side of the ship.

The hard-luck frigate may have been a loss, but all 111 of her survivors were all successfully plucked off the snow-covered beach by one intrepid “silver eagle” aviator and his primitive eggbeater.

Albeit slowly.

Amid a blizzard.

And under near constant enemy fire.

Meet Betony & Sind

Our subject started life as the Royal Navy’s Flower-class corvette HMS Betony (K274), ordered 8 December 1941– the day of the first Japanese attacks on British Hong Kong and other possessions in the Pacific, kicking off a whole new war.

Laid down 26 September 1942 at Alexander Hall and Sons in Aberdeen as Yard No. 687, the future Betony launched on 22 April 1943 and commissioned on 31 August 1943.

Her inaugural commander was the long-serving Lt. Nicholas Bryan John Stapleton, RD, RNR– who formerly was skipper of the Flower-class sister HMS Amaranthus (K 17), and before that the ASW whaler HMT Southern Pride (K 249).

WWII Service

Our vessel suffered her first loss, with Act/Petty Officer Hubert M. Jones, P/SSX 20752, of her company listed as “died of wounds” on 28 November 1943 without further elaboration.

She was soon on convoy runs, tagging along with OS.59/ KMS.33 out of Liverpool for two weeks before 1943 was out.

After further workups in Scotland and a deployment to the Eastern Fleet at Trincomalee in early 1944, Stapleton handed command of the new Betony over to T/Lt. Percy Ellis Croisdale Pickles, RNVR, on 20 October 1944. While in the Indian Ocean, she performed escort duties for a dozen slow convoys on the CJ (Calcutta to Colombo) and BM/MB (Bombay to Colombo) runs between February and October 1944.

She was loaned to the Royal Indian Navy in January 1945 and assigned to the hardscrabble Burma Coast Escort Force, operating alongside sistership corvettes HMIS Assam, HMS Meadowsweet, and HMS Tulip; the River-class frigates HMS Taff, Shiel, Lossie, Deveron, Test, and Nadder; and the old Town-class destroyers HMS Sennent (ex-USCGC Champlain) and Lulworth (ex-USCGC Chelan) out of Colombo.

When the war was all but over, Betony was officially commissioned on 24 August 1945 into the RIN as HMIS Sind, keeping her same pennant number (K274). Her only “Indian” skipper was T/A/Lt.Cdr. Leonard George Prowse, RINVR, formerly commander of the armed yacht HMS Rion (FY 024), who assumed command in March 1945.

With the corvette suffering from engine troubles, she was nominated for disposal and paid off on 17 May 1946

Bangkok Bound

Thailand had a winding path during WWII. Having fought in 1940-41 with the Vichy French over Cambodia (some things never change!), the country claimed neutrality until a near-bloodless “invasion” by Japan in December 1941, after which it entered into an outright military alliance that only ended post-VJ Day. Ceding territories its troops had seized in Burma and Malaya back to Britain and in Cambodia back to France under an American-brokered agreement in 1946, the country became the 55th nation to join the UN in December 1946 and swung more or less to the West.

This opened the country to military aid, which included receiving two surplus former RIN corvettes from Britain– ex-HMS Burnet/HMIS Gondwana (K 348) and our ex-HMS Betony/HMIS Sind on 15 May 1947. They were given a short refit and recommissioned into the Thai fleet as the frigates HTMS Bangpakong and HTMS Prasae, respectively.

HMTS Prasae

The British also transferred the humble 1,000-ton Algerine-class minesweeper HMS Minstrel (J 445), which became HTMS Phosamton (MSC-451).

The turnover ceremony was held in the naval dockyard of Singapore.

Although third-hand, the two surplus corvettes/frigates and the minesweeper were much appreciated and joined a Thai fleet that included the quaint but decrepit Thonburi-class coastal defense ship HTMS Sri Ayudhya (2,350-tons, 253 ft oal, 15 knots, 4×8″/50s, 4×3″/50s) whose sister had been sunk by the French in 1940, the 1,400-ton Japanese-built sloop HTMS Maeklong (which doubled as the royal yacht and naval cadet training ship), seven remaining pre-war Italian-built 300-ton Trad-class torpedo boats, the two old Armstrong-built Rattanakosindra-class gunboats (800 tons, 174 feet, 2×6″, 12 knots), four long-laid-up Japanese-built Matchanu-class costal submarines, and a handful of old coasters, dispatch, and survey vessels.

Later in 1947, the U.S. transferred three surplus PC-461-class 173-foot subchasers: HTMS Sarasin (ex USS PC-495), HTMS Thayanchon (ex USS PC-575), and HTMS Khamronsin (USS PC-609); and two LSM-1 class landing craft (ex USS LSM-333 and 338), further modernizing the Thai fleet, which by 1950 numbered 1,100 officers and 10,000 ratings.

Things were looking up.

Korea

In the wake of the Korean War in June 1950, Thailand was the first Asian nation (besides the exiled KMT on Taiwan, which is a whole ‘nother story) to offer ground troops to the UN Force. Before the end of the war, the anti-Chinese Prime Minister (former Field Marshal) Plaek Pibulsonggram wholeheartedly contributed over 11,700 ground troops (soon reequipped with U.S. uniforms and small arms), 40,000 tons of rice, and both of the country’s new frigates to the effort.

A newly formed unit of picked men, the 21st Infantry Regiment, Queen’s Guard (Thahan Suea Rachini), was drawn from across the Army.

Ultimately, more than 10,000 Thai troops would serve in the Korean War alongside U.S. forces, fighting notably at the Battle of Pork Chop Hill. (Photo: UN News Archives)

The two frigates, each with a picked crew of 110 officers and men, were made ready by early October 1950, and they would escort the first battalion of the Thai Army to Korea, with the latter carried on the old Japanese-built transport coaster HTMS Sichang, and the chartered merchant ship Hertamersk.

Prasae’s skipper was Prince (CDR) Uthaichalermlab Wutthichai, 35, who had learned his trade in England and had pinned on his lieutenant bars in 1938 before serving in WWII, and earning the Tritaphon Mongkut Thai among other decorations. Prince Wutthichai, the senior officer afloat, became the commodore of the little Thai squadron headed to Korea.

Some 307 Thai Navy personnel and ~1,200 troops left Thailand’s Khlong Toei port aboard the four ships on 22 October 1950, headed north. They arrived in Pusan on 7 November.

The U.S.-reequipped 21st Infantry, which soon earned the nickname the “Little Tigers,” served alongside the U.S. 1st Cavalry Division and would see hard combat in the Third Battle for Seoul and at Pork Chop Hill.

Once attached to the UN Forces on 10 November, the two Thai frigates were given a short overhaul in Japan, which included updated sonar and radar suites, then tasked for a month under CTF-95 as guard ships for the entrance to the naval roads at Sasebo, Japan, with Prasae on the morning shift and Bangpakong overnight.

Then came a more kinetic assignment.

In early January 1951, Prasae and Bangpakong were under Task Force 77 orders on the gun line off the east coast of Korea near the 38th parallel, providing fire support missions to troops ashore with their single 4-inch BL Mk.IXs, steaming with a destroyer force including USS Wallace L. Lind (DD-703) as part of the East Coast Blockading and Patrol Task Group (TG 95.2).

The first shelling operation on North Korea’s east coast by the Thai Navy began on 3 January, firing along the coast between latitudes 38 and 39 degrees North, between the cities of Changjon and Yangyang. On 5-6 January, shelling of railway stations, transportation routes, and military structures in the Chodo area was carried out.

Then came a blizzard that was so severe that it grounded carrier and most fixed wing sorties between 6 and 11 January and filled central Korea with snow showers, haze, smoke, low clouds, 30 knot winds, and fog, dropping visibility to zero and bottoming out thermometers, Prasae drifted into the shallows on the cape of Kisamun-dan in Hyeonbuk-myeon, Yangyang, Gangwon, North Korea. She was hard aground, at a 60-degree angle to the shoreline, just 200 yards offshore.

She was also in enemy held-territory some 16 klicks north of the 38th Parallel.

The Lewis S. Parks Papers in the Harry S. Truman Library contain dozens of Navy images of the rescue operation, digitized (low rez) in the National Archives. They were taken in most cases by U.S. Navy LT William DuCoing, presumably of the USS Manchester, who “witnessed several enemy soldiers killed while on this beach.”

The alert went out, and Task Force 77 sprang into action to save the stranded Thai warship and her crew.

The salvage operation included the old Gleaves-class destroyer/minesweeper USS Endicott (DMS-35), which tried to send in LCVPs to recover marooned Thai sailors, joined by Prasae’s sister Bangpakong, whose small boats attempted to approach the beach without success due to fierce surf and rollers.

Endicott’s sisters USS Thompson (DMS-38), Carmick (DMS-33), and Doyle (DMS-34) moved in to assist and clear lanes for mines. De-beaching lines were attempted by Comstock (LSD-19) and Bolster (ARS-38), which also proved unsuccessful.

Endicott rescued three Thai sailors after they were washed overboard from one of the pulling boats, but unfortunately, a fourth one drowned. Endicott’s doctor and chief corpsman also went ashore to care for casualties until they could be evacuated.

With carrier aircraft grounded due to the poor flying conditions, fire support to keep interloping Chicom and Nork troops at bay was provided by the Cleveland-class light cruiser USS Manchester (CL-83) and her companion destroyers USS English (DD-696), Borie (DD-704), Hank (DD-702), and Forrest Royal (DD-872).

Truman got a White House briefing on Prasae at least ten times during this period as part of his daily situation reports on the war.

Gunfire from the USS Manchester protected the stranded sailors and rescuers from enemy troops. NARA 350898492

Early attempts at using helicopters in the rescue proved fatal.

As noted by NHHC:

On 8 January, a Sikorsky H03S1 of Helicopter Utility Squadron TWO (HU-2) embarked on the carrier USS Valley Forge, maneuvered near Prasae when a rogue wave caused the ship to roll. The helicopter’s rotors hit the mast, causing the mast to collapse and the helicopter to crash in flames, which then ignited 20mm shells, causing more damage to the ship. The crew put the fire out in under 30 minutes. Somewhat miraculously, the helicopter pilot, Lieutenant (junior grade) John W. Thornton, his aircrewman, and a salvage officer all survived the crash, but another Thai sailor drowned.

Manchester was lucky enough to have a replacement Sikorsky HO3S-1 (H-5/S-51) helicopter (“UP27” BuNo 122715) detached from Helicopter Utility Squadron 1 (HU-1) aboard USS Philippine Sea.

Nicknamed Clementine, she was piloted by the one and only Chief Aviation Structural Mechanic, ADC (Aviation Pilot), Duane Wilbur Thorin (NSN: 3165995). An enlisted pilot who joined the Navy in 1939 at age 19 and earned his silver NAP wings after finishing flight training in 1943. The blonde-haired Thorin– eighth son of Swedish emigrants to Nebraska– moved into rotary-wing billets after the war. He had already earned something of a swashbuckling reputation, shuttling out on one-man missions to rescue downed fliers in his contraption, typically while clad in his trademark non-regulation green headgear.

Clementine wasn’t much, with her 450hp R-985 Wasp Junior only enabling her to lift about 900 pounds of useful cargo (pilot included) off the ground on a full tank of gas in good weather, but she was on hand and had enough range to shuttle back and forth from Prasae to Manchester.

With the likelihood that the grounded ship could be pulled off while under fire dropping to zero, and hypothermia setting in with the survivors who were running out of supplies and battling below-zero temperatures overnight, the order went to Clementine to pull them off, typically just two or three men at a time.

On inbound flights to Prasae, Thorin and Clementine dropped off a small medical team under Doc Myers, and a security team under LT Taylor to help guard and mark the LZ for future flights. At one point, they exchanged long-distance shots with a four-man enemy patrol just over the dunes.

They also brought blankets and some hot chow.

Meanwhile, CDR Wutthichai, the stricken ship’s skipper, directed his navigators and gunners to destroy anything that could be useful to the enemy, doused the ship with oil and placed gunpowder in various locations, and then left the ship last.

Wutthichai was likewise the final man that Clementine pulled from the beach.

Over the three days between 11 and 13 January, Chief Thorin and Clementine pulled 126 men from Prasae in 40 sorties, 111 Thai and 15 USN, bringing them all safely to Manchester’s little wooden helo deck.

Seventeen of the 111 evacuees from the Thailand corvette, HMTS Prasae, wear U.S. Navy-issued dungarees while aboard the USS Manchester. NARA 350892830

Of Prasae’s crew, two were killed in the grounding and drawn-out rescue under fire: Petty Officer 2nd Class Chan Muang-am and Petty Officer 2nd Class Phuan Phonsayam, both later posthumously promoted to CPO. Twenty-seven of her crew were injured, with a mixture of frostbite and shrapnel as the cause of wounds.

The unmanned and wrecked hulk of Prasae was destroyed by naval gunfire from USS English on 13 January, via 50 rounds of 5-inch common.

Those not hospitalized in Japan were soon shipped aboard Bangpakong.

As for her sister Bangpakong (ex-Burnet, ex-Gondwana), she remained in Korean service until February 1952 and in Thai service until stricken in 1984.

Epilogue

With the Thai government still eager to contribute to the effort in Korea, the U.S. Navy quickly sold them two laid-up Tacoma-class patrol frigates, late of the Soviet Red Banner Pacific Fleet via Lend-Lease, the USS Glendale (PF-36) and USS Gallup (PF-47), for the princely sum of $861,940.

Transferred in October 1951 at Yokosuka, Glendale became the Thai Navy ship Tachin. Gallup became the Thai Navy ship Prasae. Along with them came five more PC-461s, two LCIs, and three surplus SC-1627-class 119-foot subchasers, these smaller vessels slated for immediate service in Thai coastal waters while the frigates remained deployed.

Following a workup in Japanese waters, the new Prasae and Tachin departed Sasebo on 12 January 1952 in company with sistership USS Bisbee (PF 46) on their first escort mission since their purchase by and addition to the Thailand Navy.

The new pair of frigates served for the duration of the Korean War and well into the tense shift into peace, rotating crews with fresh ones shipped in from Thailand at least twice. Both departed South Korea for their first trip home on 22 January 1956, nearly three years after the shooting had stopped! Some 2,485 Thai naval personnel served in Korean waters, with 1,679 of them receiving UN service medals. Two Thai naval personnel were also awarded U.S. Bronze stars.

In the course of Thailand’s involvement in the Korean War, the country suffered 1,273 casualties, comprising 129 killed in action (including two Navy), 1,139 wounded, and 5 missing. The country maintained a company-sized infantry force in the ROK to watch the DMZ until July 1972. They continue to contribute two officers and 13 enlisted to the more or less permanent UNC Military Armistice Commission-Secretariat (UNCMAC-S) in South Korea today.

Speaking of South Korea today, with the border shifting slightly to the line of contact in place when the armistice was signed, the cape that Praese was grounded on has been part of the ROK since 1953, and these days is often referred to as “38th Parallel Beach,” a popular surfing spot (in the summer).

Prince Wutthichai, Praese’s final skipper, returned home with his crew in March 1951, married Princess Vimolchat, and had two children. Decorated with the Order of the White Elephant in 1953, he passed just five years later, aged 43. There seems to be a story there.

Chief Thorin fully earned a Distinguished Flying Cross for his rescue efforts on the grounded Prasae, then added a Gold Star to his DFC in November 1951 while flying from the cramped deck of the cruiser USS Toledo (CA-133) to successfully pluck a downed pilot trapped some 60 miles behind the enemy’s lines. He added a second Gold Star to his DFC in January 1952 while operating from USS Rochester (CV-124) for picking up two downed pilots just offshore of Hungnam– while under small arms fire from the edge of the beach– in two separate trips.

Just six months after the rescue of Prasae’s crew, Clementine, the helicopter used so successfully, UP 27 (BuNo. 122715), went missing on a rescue mission near Kosong, Korea, with her pilot killed and crewman taken prisoner. Luckily, Chief Thorin was not at the controls that day.

Thorin’s luck ran out in February 1952 when flying a whirlybird from Rochester on a mission to rescue an injured and critically ill Skyraider pilot off Valley Forge— LT(j.g) Harry Ettenger of VC-35– who was down behind enemy lines and being harbored by anti-Communist North Korean partisans. The mission, over known enemy anti-aircraft positions near Kojo, Korea, was almost successful, but at the last minute, Thorin’s helicopter crashed due to mechanical problems. Taken prisoner along with Ettenger, he was a resident of POW Camp 2 until his release during Operation Big Switch on 2 September 1953. He earned a Silver Star for the mission (recommended for the Navy Cross), adding to his three DFCs.

Thorin made over 130 rescues in hostile territory during the Korean War, not counting those from Prasae.

Thorin retired from the Navy in 1959 as a lieutenant and passed “feet dry” in 2002, aged 82. He is buried at Chambers Cemetery, Holt County, Nebraska, Block 1, Lot 35.

Thorin was used as the basis for CPO (NAP) Mike Forney, the enlisted CSAR pilot in The Bridges at Toko-Ri by Pulitzer Prize winner James Michener. Icon Mickey Rooney portrayed him in the movie adaptation, which was filmed in Technicolor in 1954 aboard the USS Oriskany (CV-34). Real UP-coded H-5s were used, and Rooney portrayed his based-on-a-real-story character well, albeit with a green tophat and scarf rather than Thorin’s more understated green ballcap.

That’s Hollywood for you.

Warship Wednesday 19 November 2025:  Pride of the Scouting Group

Photographed by A. Renard of Kiel, Germany, via the Naval History and Heritage Command, NH 45198

Above we see the Roon-class armored cruiser (panzerkreuzer) SMS Yorck of the Kaiserliche Marine, passing under the famous Levensauer Hochbrücke along the Kiel Canal prior to the Great War.

She was commissioned 120 years ago this week and, a beautiful ship, had a short but tragic peacetime career and even shorter and more tragic wartime service without ever firing a shot in anger.

The Roons

In the 1890s, the German Imperial Navy moved to field several armored cruisers, initially rebuilding old (circa 1870s) ironclads with newer and more modern guns and updated engineering plants.

Then came the majestic 11,500-ton SMS Fürst Bismarck, the country’s first purpose-built armored cruiser, laid down in 1896. Built for 18 million gold marks, Fürst Bismarck was capable of 18.7 knots and carrying a main battery of four 9.4″/40s and a secondary of 12 5.9″/40s, while clad in up to 7.9 inches of armor plate. Bismarck was followed in 1898 by the smaller (and cheaper, at 16 million marks) SMS Prinz Heinrich (9,800t, 2×9.4″/40, 10x5.9-inch SK L/40s, 20 knots, 5.9-inch armor).

Then came the twin SMS Prinz Adalbert in 1900 and Friedrich Carl in 1901, which were basically a three-funneled improvement of the preceding Prinz Heinrich, while carrying a different main armament (four 8.27-inch SK L/40 C/01s rather than 2×9.4″/40s) and thinner but better armor with the secondary armament (10×5.9″/40s) housed in a central armored citadel amidships and a 21 knot speed on a 18,500shp plant.

Jane’s 1914 entry for the armored cruisers SMS Prinz Adalbert and Friedrich Carl.

Continuing that vein, the 1902-03 Naval Program ordered a pair of essentially improved Prinz Adalbert-class cruisers, dubbed initially Ersatz (more or less “replacement”) Kaiser and Ersatz Deutschland as they were replacing the old ironclad/armored cruiser conversions on the German Navy List. The differences between the new cruisers and their Adalbert-class half-sisters came in the fact that they had four funnels rather than three, with 16 boilers rather than 14 on a more powerful 20,000 shp plant.

Armament was largely the same primary (four 8.27″40s with 380 rounds) and secondary batteries (ten 5.9″/40s with 1,600 rounds), while the tertiary battery was slightly larger (14 24-pounders with 2,100 rounds vs 12 24-pounders with 1,800 rounds). Four 17.7-inch torpedo tubes were fitted below the waterline– one each in the bow and stern, and one on each side approximately at the level of the forward twin turrets– with 11 torpedoes in the magazine.

The two new cruisers, Ersatz Kaiser and Ersatz Deutschland, entered the fleet as SMS Roon and SMS Yorck, constructed eight months apart at Kaiserliche Werft, Kiel, and Blohm & Voss, Hamburg, respectively.

For reference, the Germans liked the design of Roon and Yorck so much that they ordered another pair of armored cruisers in 1904 to an improved design, the larger (and 25 percent more expensive, at 20-million marks each) Scharnhorst and Gneisenau of later Maximillian Von Spee fame.

Jane’s 1914 entry for the armored cruisers SMS Scharnhorst and Gneisenau. These were just bigger Roon-class cruisers with more speed and range but roughly the same armament and armor.

Following Scharnhorst and Gneisenau, the Germans in 1906 ordered their last armored cruiser, the huge 15,000-ton 12x 8.4″/45 gunned SMS Blücher (which cost 28.5 million marks), then shifted gears to battlecruisers with the 21,000-ton 11-inch gunned SMS Von der Tann (36.5 million marks) in 1907.

With that…

Meet Yorck 

Our subject carries the name of Johann David Ludwig Graf Yorck von Wartenburg, a Prussian feldmarschall and statesman of the early 19th century.

An ardent patriot, Yorck resented Prussia’s subservience to Napoleon and, in 1812, defied the orders of Wilhelm Friedrich III by initially refusing to join the French emperor’s great invasion of Russia. With Napoleon’s retreat from Moscow, Yorck seized the opportunity for liberation and negotiated a separate peace treaty (the Convention of Tauroggen) for his Corps with Russian General Ivan Ivanovich Dibich-Zabalkansky over the Christmas holiday of 1812 without the consent of their respective monarchs. He went on to fight Napoleon for the next three years and retired from the Prussian Army in 1821, passing nine years later.

Yorck, a thorn in Napoleon’s side, later became a favorite icon of the newly unified Germany.

Laid down as Ersatz Deutschland (Baunummer 167) at the Blohm & Voss in Hamburg on 25 April 1903, the hull of the future SMS Yorck was launched into the water on a warm 14 May 1904, christened by Josephine Yorck von Wartenburg, the 45-year-old granddaughter of the famous field marshal. Speaking of field marshals, the 71-year-old Gen. Wilhelm Gustav Karl Bernhard von Hahnke, then the Oberkommando in den Marken over state functions, read the dedication to the new cruiser.

Yorck, launched. Note her ram bow

Yorck, despite being laid down eight months later, managed to be completed six months earlier than her sister Roon, commissioning on 21 November 1905, while the class leader entered service on 5 April 1906.

Yorck’s construction costs were 16,241,000 goldmarks, while Roon came in at a comparatively cheaper 15,345,000 goldmarks. Still, they both came in cheaper than the previous twins, the 16.4 million mark Prinz Adalbert and the 15.7 million mark Friedrich Carl. Roon is listed as costing £875,733 (£660,469 hull and machinery, £195,695 guns, £19,569 torpedo armament) in a British journal.

She and her sister joined the fleet’s reconnaissance force (Aufklärungsstreitkräfte), with Yorck taking over the task of flagship from Friedrich Carl. The flagship role would remain with Yorck until May 1908, then again from March 1909 to April 1910, and intermittently in 1912 and 1913. Whenever she wasn’t the direct flagship, she typically carried the recon force’s second or third commander and staff.

She spent the next several years in a series of fleet maneuvers and squadron cruises into the Atlantic, ranging as far as Spain and Norway.

She not only looked good but could shoot as well. Yorck won the Emperor’s Shooting Prize (Kaiser Preis) for large cruisers in both 1908 and 1910.

Meanwhile, sister Roon, unburdened by flagship roles, even managed a sortie to escort ships to the far east and attend the 1907 Jamestown Exhibition naval parade in New York City along with the protected cruiser SMS Kaiserin Augusta.

S.178

While practicing counter-torpedo boat operations on the night of 4 March 1913, just northeast of Heligoland, Yorck inadvertently rammed the low-lying and fast-moving S.178, driving the 800-ton ship under the waves, and sending 69 men with her to the bottom. Just 15 survivors were saved through the combined efforts of fellow torpedo boat S.177, Yorck, and the battleship SMS Oldenburg.

The 242-foot S.138-class torpedoboot S.178 was cut in half by Yorck in March 1913 but was salvaged (during which one of the salvage vessels, Unterlebe, capsized in heavy seas, carrying another seven men to the bottom). Her two pieces reconstructed, she survived the Great War and was surrendered to the British, who scrapped her in Dordrecht in 1922.

Doldrums

As the Kaiser built out his shiny new High Seas Fleet and a fresh batch of battlecruisers joined it, the still young but smaller, weaker, and slower armored cruisers were put to pasture to free up their crews for reassignment. Prinz Heinrich was laid up from 1906 to 1908 and then put into limited service as a training ship. Likewise, in 1909, Friedrich Carl was withdrawn from front-line service and re-tasked as a torpedo training ship. Prinz Adalbert became a gunnery school and test ship in 1912.

Roon was laid up in September 1911 after just five years of service, while Yorck soon followed her sister and was laid up on 21 May 1913, having completed less than eight years of service. It probably didn’t help that the high-profile ramming of S.178 had occurred just ten weeks prior. Most of Yorck’s crew, including the skipper, transferred to the newly completed battlecruiser SMS Seydlitz.

Yup, that Seydlitz.

SMS-Seydlitz seeing what hell looks like at Jutland, by Carl Becker

Scharnhorst and Gneisenau were only on active service in 1914 due to their overseas assignment with the East Asian Squadron, while Blucher was, well, a proto if under-gunned battlecruiser. If you ask me, it’s likely that on a long enough timeline, the Germans would have replaced von Spee’s armored cruisers with battlecruisers in the same way that the Moltke-class BC SMS Goeben was stationed in the Mediterranean from 1912 onward.

Anyhow…

War!

When the lights went out across Europe in August 1914, Yorck and Roon were pulled out of reserve and rushed back into service, both attached to the III. Aufklärungsgruppe, with Roon, made the group flag.

The squadron initially operated in the Baltic Sea, then later shifted to the North Sea.

On 2 November, the 3rd Scouting Group helped cover the first offensive operation of the High Seas Fleet– the bombardment by the battlecruisers of the 1st Scouting Group of Yarmouth, the first attack on British soil in 250 years. While no casualties were suffered on either side and the Germans retired in good order, Yorck would upend that empty victory.

While wrapped in fog in the inner Jade estuary on the morning of 4 November, Yorck’s skipper, KzS Waldemar Pieper– a skilled professional officer who had signed up in 1887 as a cadet and had commanded both the armored cruisers Prinz Adalbert and Blucher before the war– had reason to believe his ship’s water supply was contaminated and ordered her to weigh anchor and proceed to Wilhelmshaven without pilots. The pilot had refused to take over the conn due to the poor visibility and the considerable risk of German defensive minefields, which were known but subject to tidal drifting.

At 0410, Yorck struck a mine, then turned away to escape the field and hit a second one, soon capsizing and turning turtle, entombing fully half of her crew. If not for the efforts of the old Siegfried-class coastal defense ship (küstenpanzerschiffen) SMS Hagen rushing out to her rescue despite the mines, the other half (the chagrined Pieper among them) would surely have succumbed to hypothermia.

The German armored cruiser SMS Friedrich Carl was sunk by a pair of Russian mines in the Baltic Sea almost a year to the day later, in November 1915

Yorck and Friedrich Carl were in the club of over a dozen cruisers claimed by mine warfare between 1904 and 1942, including the British cruisers HMS Cassandra, Amphion, Hampshire, and Neptune; the Japanese cruisers Miyako, Saien, and Takasago; the Italian cruisers Carlo Alberto Racchia, Carlo Mirabello, and Cesare Rossarol; the Russian cruisers Boyarin, Peresvet, and Ladgoda; USS San Diego (ACR-6), the French cruiser Kléber, and the Ottoman cruiser Mecidiye.

Yorck’s sister Roon was decommissioned in Kiel on 4 February 1916 and, after being disarmed and used as a training hulk for U-boat crews, was slated for conversion to a seaplane carrier.

Epilogue

Lost in shallow water with some elements of her wrecked hull at the time just 10 feet below the surface, between 1926 and stretching to 1983, Yorck was slowly blasted and salvaged, then later broken up in place on the seabed as a navigational hazard, finally being dredged under to effectively bury what remained.

These days, about the only relics of Yorck that endure are period postcards.

The Germans may have tried to recycle the name of our cruiser in the lead ship of the nascent Ersatz (replacement) Yorck-class of battlecruisers, whose two sisters would have, at least initially, been named Ersatz Gneisenau and Ersatz Scharnhorst. Big 38,000-ton beasts with a planned 90,000shp on tap from a suite that included 32 boilers and four geared steam turbines, the Ersatz Yorcks were a sort of Super Mackensen type that would have made 27 knots while still carrying eight 15″/45 guns (as opposed to SMS Mackensen’s eight 13.8″/45s) and as much as 10 inches of armor plate. Ersatz Yorck had her keel laid at AG Vulcan in Hamburg in July 1916, but with production resources pivoting to U-boats, she never stood a chance and was eventually abandoned and broken up on the ways after the war. Her design did reportedly prove a starting point for the Kriegsmarine’s later Scharnhorst-class battleships, however.

Our Yorck’s captain’s cabin was an important stepping stone for several future German admirals.

Her first skipper, KzS Leo Jacobson, by 1918 was a vice admiral and the fortress commander of Wilhelmshaven.

Her second commander, KzS Arthur Tapken, went on to head the Navy’s intelligence section, led a scouting squadron early in the Great War from the bridge of the battlecruiser SMS Von der Tann, and ended the war as a vice admiral and the fortress commander of Kiel.

Her fourth commander, KzS Ludwig von Reuter, went on to be the ignoble final commander of the High Seas Fleet, interned at Scapa Flow, and would order it to scuttle in June 1919.

KzS Max Köthner, Yorck’s fifth skipper, was director of the torpedo department at the shipyard in Wilhelmshaven, retiring in 1919 as a rear admiral.

Our cruiser’s sixth skipper, KzS Moritz von Egidy, famously commanded the Swiss-cheesed battlecruiser SMS Seydlitz at Jutland and ended the war as commandant of the Mürwik Naval Academy.

As for her seventh and final skipper, Waldemar Pieper was court-martialed in Wilhelmshaven for the sinking of the Yorck and sentenced to two years’ imprisonment in a fortress for disobeying orders and negligence. However, requested by name by Admiral Wilhelm Souchon as an artillery expert, he was paroled and seconded in February 1915 to Ottoman Turkey on probation, where he later distinguished himself to such an extent that Kaiser Willy commuted his sentence in December 1915. An Ottoman Pasha and major general, by 1916, he was the head inspector of the Turkish ordnance plants (Türk Silah Dairesi ve fabrikalari komutani) clustered around Constantinople, with 700 German experts supervising 14,000 local munitions workers. He returned to Germany in July 1917 to serve in the weapons bureau, and Pieper was later retired as a rear admiral (Konteradmiral) in 1919. He passed in early 1945, aged 73.

Sun Shines on the Commissioning of the final Indy LCS

Posted on by 2 comments

The brand-spanking-new Independence-variant littoral combat ship USS Pierre (LCS 38) was brought to life in a ceremony held in Panama City over the weekend in shorts and flip-flop weather, “Under the Bright Florida Sky.”

This came while the landlocked namesake city of Pierre, South Dakota, was basking at a high temperature of 45 degrees.

We’ve posted numerous images of Pierre over the past year during her fitting out at Austal in Mobile, where she was the last of 19 Indies built. Fincantieri is still building the last LCS, the 16th Freedom-class variant, USS Cleveland (LCS-31).

The fact that Pierre was commissioned at PC is telling, as the Indies are seemingly tasked as fast minesweepers, and NSWC Panama City is the Navy Research, Development, Test & Evaluation Laboratory dedicated to mine warfare. In fact, it was established in 1945 as the U.S. Navy Mine Countermeasures Station.

Three Indies– the USS Canberra (LCS 30), Santa Barbara (LCS 32), and Tulsa (LCS 16)— are currently forward-deployed to Bahrain with new MCM mission modules, replacing the legacy Avenger-class ships that have served in Task Force 55 for over 30 years

The current Pierre is the second warship to carry the name, after a 173-foot patrol boat, PC-1141, which served from 1943-58. Hopefully, the new one bests the previous namesake’s 15-year record of service.

Minehunting in style

Posted on by Leave a comment

The first City-class mine countermeasures vessel in active service has arrived on station, with the Belgian mine hunter Oostende (M940) pulling into Zeebrugge earlier this week.

The soon-to-be-donated Tripartite class mine hunter Lobelia (M921) met her at sea and escorted her home.

The 1980s vintage Tripartites are being replaced in Belgian, French, and Dutch service with the City-class vessels, which, as you can see above, are a huge upgrade.

The 2,800-ton, 270-foot City class carries a BAE Bofors 40mm Mk4 DP mount forward and two FN Herstal Sea deFNder remote mounts with FN M3R .50 cal heavy machine guns (one on the starboard bridge wing and the other overlooking the port stern). There are also four multipurpose mounts for GPMGs, LRADs, and water cannons for more constabulary sort of work.

The aviation deck is designed to carry and operate a pair of 500-pound UMS Skeldar V-200 rotary UAVs, also enabling vertical replenishment, personnel insertion/extraction, and HIFR via manned helicopters.

The boats carried include a 40-foot waterjet-propelled Exail Inspector 125 sonar-equipped USV mine buster and two 23-foot RHIBs.

The Skelar UAVs and Exhail Inspector USVs are depicted in use below:

In addition to a 33-man crew, they can carry another 30 transients, including divers and security teams/marines.

Compare this to the 600-ton/169-foot Tripartites, which still rely mainly on on-board sonar and surveys to dispatch clearance divers. Their armament is a 20mm gun and four MGs.

The Belgians had 10 Tripartites and have since passed seven of them on to Pakistan, France, Ukraine, and Bulgaria, with the final three set to be donated to Bulgaria in the coming months.

The Dutch had 15 Tripartites but have passed on all but the final three to Latvia, Pakistan, Bulgaria, and Ukraine. They plan to move the last trio to Bulgaria by 2028.

France had 10 original Tripartites and has decommissioned and disposed of five, with six remaining.

The plan is to replace them all with City-class vessels, with all three countries ordering six ships each.

Wouldn’t it have been great if the 14 retired/retiring 40-year-old U.S. Navy Avenger-class mine countermeasures ships had been replaced with a dedicated design more akin to this and less, well, LCS?

Pour 12 out for the ever-maligned yet everlasting Kingstons

Posted on by Leave a comment

Over the past several years, I have made no bones about my admiration for the 12 humble yet effective Kingston-class Maritime Coastal Defence Vessels (MCDV) of the Royal Canadian Navy.

Kingston-class MCDVs HMCS Glace Bay (MM 701) and HMCS Shawinigan (MM 704)

For the bottom line of $750 million (in 1995 Canadian dollars), Ottawa bought 12 ships, including design, construction, outfitting, equipment (85 percent of Canadian origin), and 22 sets of remote training equipment for inland reserve centers.

These 181-foot ships were designed to commercial standards and intended “to conduct coastal patrols, minesweeping, law enforcement, pollution surveillance and response as well as search and rescue duties,” able to pinch-hit between these wildly diverse assignments via modular mission payloads in the same way that the littoral combat ships would later try.

Canadian Kingston-class coastal defence vessel HMCS Saskatoon MM 709 note 40mm gun forward MCDV

Manned with hybrid reserve/active crews in a model similar to the U.S. Navy’s NRF frigate program, their availability suffered, much like the Navy’s now-canceled NRF frigate program. This usually consisted of two active rates– one engineering, one electrical– and 30 or so drilling reservists per hull. Designed to operate with a crew of 24 for coastal surveillance missions with accommodation for up to 37 for mine warfare or training, the complement was housed in staterooms with no more than three souls per compartment.

With 12 ships, six were maintained on each coast in squadrons, with one or two “alert” ships fully manned and/or deployed at a time, and one or two in extended maintenance/overhaul.

Intended to have a 15-year service life, these 970-ton ships have almost doubled that. These shoestring surface combatants were pushed into spaces and places no one could have foreseen, and they have pulled off a lot– often overseas, despite their official “type” and original intention.

However, all good things come to an end, and the Kingstons are slated for a long-overdue retirement this year.

The class in retrospect:

Army deploying new ‘terrain-shaping munition’ to Europe

Posted on by One comment

The 2nd Cavalry Regiment, based at Rose Barracks in Vilseck, Germany, will be the first unit to field the recently IOC’d XM204 Top Attack Terrain Shaping Munition.

The regiment is the longest continuously serving cavalry unit in the Army and plays a key role in the North Atlantic Treaty Organization’s Enhanced Forward Presence initiative.

“For units on the frontlines of deterrence in Europe, having access to advanced terrain-shaping capabilities like the XM204 strengthens our ability to influence key terrain, slow adversary movement, and protect our forces,” said Maj. Gen. John T. Reim, Joint Program Executive Officer for Armaments and Ammunition and Commanding General of Picatinny Arsenal. “This system gives our warfighters a decisive edge as we train and operate alongside NATO allies.”

What is the XM204?

Built by Textron, the XM204 has been in development since 2022 and is a low-profile hand-emplaced anti-tank “smart” mine of a sort.

At 84 pounds, it includes four bouncing top attack munitions with Tantalum explosively formed penetrators that can be fired independently and reach out to 50 meters from the device.

It holds four of these little guys

Rather than old anti-tank mines that require a vehicle weighing over 4 tons to be driven over, the XM204 utilizes seismic sensors with a classified range and, according to reports, programmable target profiles to distinguish between, for example, a bulldozer and a T-72.

Some say it can distinguish between an Abrams and a T-72 as well, which is interesting, but I wouldn’t want to be the Abrams platoon commander to try that for the first time.

It has a 30-minute delay in arming and a timed self-destruct (4 hours, 48 hours, or 15 days) to inert itself if not reclaimed and has “anti-tamper” features to keep the bad guys from using them. They can be collected by follow-on troops and redeployed if they haven’t been tripped.

The XM204 has been successfully used against T-72s at Yuma Proving Ground.

It is interesting to imagine what Rommel and Montgomery would have done with 10 pallets of these in North Africa in 1942.

‘Pre-Wetting’ the old Girl

Posted on by Leave a comment

Some 70 years ago this week, 28 September 1955.

“Pre-wetting” tests on the County (Kent)-class heavy cruiser HMS Cumberland (57), at the time, the nearly 30-year-old WWII veteran was the Royal Navy’s “trials cruiser,” in the Mediterranean during Atomic trials.

IWM (TR 7056)

Pre-wetting is a method of protecting warships against radioactive particles while operating in a fallout area, the outer fringe of the region affected by an underwater nuclear explosion.

“It involves the continual washing of all weather surfaces of the ship during and after contamination, as experiments showed that fission matter was less likely to adhere to a surface while it is being subjected to salt water washdown.”

Cumberland, which narrowly missed out on chasing down the “pocket battleship” Graf Spee in 1939, went on to earn battle honors for the Arctic (1942-43), North Africa (1942), Sabang (1944), and Burma (1945).

She was placed in Reserve in May 1959 and sold to BISCO for breaking up by J Cashmere at Newport where the ship arrived under tow on 3 November that year. Her name was carried on by the 11th Cumberland since 1695, a Type 22 frigate (F85) commissioned in 1989 and decommissioned in 2011.

Above we see the Allen M. Sumner-class destroyer USS De Haven (DD-727) as she supports the first and second waves of landing craft moving toward Red Beach at burning Inchon at 0700 on 15 September 1950, some 75 years ago this week, as photographed from a Marine Air Group Twelve (MAG-12) aircraft, from either VMF-214 or VMF-215.

In more ways than one, despite her service in three real-life shooting wars and a long-running tasking as a guinea pig, the “Ravin’ D” would become the poster child for Inchon, and for good reason.

The Sumners

The Sumners, an attempt to up the firepower on the previous and highly popular Fletcher-class destroyers, mounted a half-dozen 5″/38s in a trio of dual mounts, as well as 10 21-inch torpedo tubes in a pair of five-tube turntable stations. Going past this, they were packed full of sub-busting and plane-smoking weapons as well as some decent sonar and radar sets for the era.

Sumner class layout, 1944

With 336 men crammed into a 376-foot hull, they were cramped, slower than expected (but still capable of beating 33 knots all day), and overloaded (although they reportedly rode wildly when in light conditions). Still, they are fighting ships that earned good reputations for being almost indestructible.

Cost per hull, in 1944 dollars, was about $8 million, excluding armament, compared to the $6 million price for a Fletcher, a big jump.

Meet De Haven

Our vessel was the second Navy ship named in honor of LT Edwin Jess De Haven.

Born in Philadelphia in 1816, joined up with the fleet age the ripe old age of 10 as a midshipman and made his name as an early polar explorer, shipping out with the Wilkes Expedition (1839-42), and looking for Sir John Franklin’s lost polar expedition as skipper of the humble 81-foot brigantine USS Advance in 1850 as part of the Grinnell expedition. Placed on the retired list in 1862 due to failing eyesight, he passed in 1865.

His aging granddaughter, Mrs. Helen N. De Haven, made the trip to Maine’s Bath Iron Works from her home in Ardmore, Pennsylvania, in 1942 to participate in the launching ceremony for the first ship to carry his name, the Fletcher-class destroyer DD-469. Commissioned on 21 September 1942, that valiant greyhound was sunk just 133 days later, the 15th American destroyer lost in the Guadalcanal campaign.

The second De Haven was a member of the much-improved Sumner class. Laid down once again at Bath Works on 9 August 1943 (just two days after the contract, NOBs-309, was issued), she was BIW Hull #228.

The late LT De Haven’s granddaughter, then 56, dutifully came to christen this second destroyer as well on a chilly 9 January 1944, sending the hull into the embrace of the Kennebec River. We all pitch in where we can in wartime.

As detailed by the Bath Independent:

Commissioned 31 March 1944, her construction ran just 235 days.

Her plank owner crew was led by CDR John Bagley Dimmick (USNA 38), who would be De Haven’s skipper through the following June. Before joining De Haven, Dimmick had earned a Legion of Merit while on the staff of Commander Destroyers, Atlantic Fleet, on the team to improve the effective operation of the 5-inch gun batteries in destroyers.

On 9 July, she became the flagship of Desron 61 (Desdiv 121 and 122), the second squadron of Sumners, made up of USS Mansfield (DD 728), Lyman K. Swenson (DD 729), Collett (DD 730), Maddox (DD 731), Blue (DD 744), Brush (DD 745), Taussig (DD 746), and Samuel N. Moore (DD 747), with Capt. Jesse H. Carter moving aboard with his staff for the duration of the war.

After shakedowns in Bermuda, De Haven pulled the mission to escort the small old flattop USS Ranger (CV 4) from Norfolk– capping the carrier’s Atlantic service– to the Pacific, where the Torch veteran would be tasked with preparing air groups out of Pearl Harbor for combat operations on the sharp end.

Dropping off Ranger in Hawaii on 3 August 1944, De Haven continued onward, escorting west-bound convoys including the carriers USS Enterprise, Intrepid, and Independence to Eniwetok before joining the fast carriers of TF 38 at Ulithi for operations in the Philippines, arriving just off Luzon as an escort with these carriers of TU 38.1.3 on 4 November.

She would continue such screens through January 1945, including raids along the Indochina coast and Formosa, with notable incidents including the rescue of a downed VF-7 Hellcat pilot from USS Hancock on 14 December and steaming through Typhoon Cobra on 17/18 December, coming to within about 35nm of the storm’s center while registering sustained 55 knot winds and mountainous seas.

De Haven spent the next several days combing the debris scattered seas for survivors from three other destroyers that were not as lucky.  No less than 718 souls perished at sea during the typhoon. Nimitz noted later that “It was the greatest loss that we have taken in the Pacific without compensatory return since the First Battle of Savo.”

February 1945 brought the Iwo Jima landings and more carrier screening. It was during plane guard duties for USS Bennington on 12 February that a TBF of VT-82 was struck by a rocket accidentally fired from a Hellcat of VF-82, causing the death of two of the three men aboard the Avenger. One of De Haven’s crew, PhM2c Edward Price, dove into the open sea and rescued the pilot, Ensign Paul F. Cochran, who was being dragged under the hull by the weight of his sinking parachute. Price was recommended for the Navy and Marine Corps Medal.

On the 16th, she stood by her carriers as they made the first attacks on the coasts of the Japanese main islands since the Doolittle Raid. While the Doolittle carriers never made it closer than 650 miles from Japan, De Haven logged her position as only 150.

1/2 March saw her engage in some good old-fashioned naval bombardment, soaking Okino Daito Jima from close offshore with other destroyers overnight. She expended 14 rounds of 5″/38 Common, 432 of 40mm, and 815 of 20mm.

This dovetailed into the Okinawa landings and near constant anti-air watches for weeks, continuing this task through 13 June, including firing on at least three bogeys that came in close, counting a “sure assist” kill on an Emily. She proved a worthy lifeguard for a second time, pulling 1LT H.F. Pfremmer, USMCR, a member of Bennington’s fighter group, from the sea on 14 May.

She once again was allowed a break from plane guard and air defense duties for another fire mission, hitting Minami Daito Jima on 10 June with 104 5″/38 Common, including 23 two-gun salvos, seven four-gun salvos, and five satisfying six-gun salvos. She had hit the island on 21 April already, firing 90 rounds at its airstrip just before sunset.

Oh yeah, and she survived a second maelstrom, Typhoon Connie, during which she saved a third aviator, a pilot from USS Hornet. The “half-drowned” pilot, Lt (j.g.) John David Loeffler, USNR, was plucked from the water just eight minutes after he hit the drink, rescued by PhM2c Robert Wayne Simmons, who swam to the aviator to buckle a chest strap around him so that he could be lifted aboard with a whip hoist. Simmons was recommended for the Navy and Marine Corps medal.

Then came operations directly against the Japanese home islands proper.

On 9 July, she assumed a radar picket station some 20 miles (later 50 miles) West of the center of her task force. There, she was a control ship for inbound U.S. and RN strikes, as well as an early warning tripwire for rarely seen Japanese aircraft headed out to sea, and as a floating life guard station. She and her DesRon 61 sisters would remain on this duty through 15 August, with De Haven sinking over a dozen floating Japanese mines with 20mm cannon fire, and rescuing several downed aviators (including Lt CW Moore, USS Shangri La, 15 July; Ensign Frank Kopf, Bennington, 25 July; and Ensign J.A. Lungren, Bennington, 13 August).

She also took part in an epic littoral raid from the sea.

Overnight of 22/23 July 1945, Desron 61, De Haven included, swept Sagami Bay– lower Tokyo Bay.

With each of the Sumners mounting six 5″/38s, they could get off a tremendous amount of fire when needed.

Detecting a Japanese convoy of four vessels at 2305 while still 33,000 yards away, the chase was on. Closing to within 11,000 yards by 2353, the engagement took just 16 minutes and saw the DDs fire 3,291 5-inch shells and let fly some 18 torpedoes.

The score? One Japanese merchant ship was sunk– the freighter No.5 Hakutetsu Maru (810 t), and the other, Enbun Maru (7,030 t), was damaged. The escorting IJN minesweeper (No. 1) and subchaser (No. 42) were unharmed. The little convoy was carrying a disassembled aircraft factory and was headed to Korea to set up shop, a trip that was aborted after the battle.

The American losses were zero.

As noted by the National WWII Museum, the engagement, termed today the Battle of Sagami Bay, was “the first time U.S. Navy ships entered the outer reaches of Tokyo Bay since April 1939.”

While DesRon 61 never received a commendation for the action, Halsey himself signaled afterward, pointing out that the force rode heavy post-typhoon seas into the Bay with great effect:

“Commander Third Fleet notes with great satisfaction the success of this well-planned and executed attack.

Commander Destroyer Squadron 61 is to be congratulated on the sound judgment, initiative and aggressive spirit displayed in ‘beating the weather’ to drive this attack home at the very door of the Empire.

You are unpopular with the Emperor. Well done”

When the war ended on 15 August, De Haven and her squadron were stationed closer to the Japanese mainland than any other Allied surface ships in Halsey’s Third Fleet.

She was one of just 48 Allied (37 American) destroyers at anchor in Tokyo Bay during the Surrender Ceremony on 2 September 1945, with the ghost of the old DD-409, lost at Guadalcanal, no doubt present alongside.

There, she flew the two-star flag of RADM John F. Shafroth, ComBatRonTwo. De Haven anchored just 1,000 yards off Missouri, close enough to almost smell the ink on the documents.

From her seven-page War History, a good recap:

De Haven sailed on 20 September for the States with four battleships and two other destroyers, loaded with “stateside” bound passengers, and arriving at San Francisco on 15 October after a brief stopover at Pearl Harbor.

Between 1 February 1946 and 3 February 1947, De Haven served in the Western Pacific, joining the 7th Fleet in operations off the coast of China and patrolling off the Japanese coast.

De Haven received five battle stars for World War II service:

*Leyte Operation, Luzon attacks: 5-6, 13-14, 19-22 November and 14-16 December 1944
*Luzon Operation
-Luzon attacks — 6-7 January 1945
-Formosa attacks — 3-4, 9, 15, 21 January 1945
-China Coast attacks — 12 and 16 January 1945
-Nansei Shoto attacks — 22 January 1945
*Iwo Jima Operation
-Assault and occupation of Iwo Jima — 15 February – 4 March 1945
-Fifth Fleet raids against Honshu and the Nansei Shoto —15-16, 25 February, 1 March 1945
*Okinawa Gunto Operation
-Fifth and Third Fleet raids in support of Okinawa Gunto operations — 17 March – 11 June 1945
*Third Fleet Operations against Japan — 10 July – 15 August 1945

Four of the class were lost to enemy action during the war:

  • USS Meredith (DD-726) struck a mine on D-Day Plus 1, following supporting the landing at Omaha Beach, then was attacked and sunk on the way back to England.
  • USS Cooper (DD-695) was torpedoed and sunk on 3 December 1944 by the Japanese destroyer Take at Ormoc Bay.
  • On 12 April 1945, USS Mannert L. Abele (DD-733) was sunk by an Ohka (Baka) bomb during the Okinawa Campaign
  • USS Drexler (DD-741) met the same fate when she was sunk by a Japanese Kamikaze on 28 May 1945.

Korea!

Based in Japan, on 26 June 1950, De Haven and her sister USS Mansfield (DD-728) were tasked to assist in the emergency evacuation of some 700 U.S. citizens and foreign nationals from Seoul, which would fall two days later.

Just four days after the North Korean People’s Army crossed the 38th Parallel, on 29 June, the light cruiser USS Juneau (CLAA 119), packing a dozen 5″38s, in company with De Haven, fired the first naval shore bombardment of the Korean War, hitting North Korean troop concentrations at Bokuku Ko. She then performed plane guard duties for the carrier USS Valley Forge and served as the commo link between the Pusan Perimeter and the tug USS Arikara (AT-98), the inshore landing control vessel.

Tasked with blockade work along the coast, De Haven bombarded an enemy battery near Pohang on 20 August, where, working with the heavy cruiser USS Toledo, they broke up a tank attack and destroyed artillery positions. De Haven then encountered a medium vessel and three small boats on 7 September, sinking all.

Soon, De Haven was tasked to support the amphibious counterpunch to Pusan, the Inchon Landings. The beach and Wolmi-do island were held by 2,000 Norks, including the 226th Marine Regiment, to which two companies of the 2d Battalion, 918th Coast Artillery Regiment were attached with their Soviet-manufactured 76mm guns.

Task Force Group Element 90.62, consisting of De Haven and her fellow DesRon 9 Sumner sisterships USS Gurke (DD-783), Mansfield, Lyman K. Swenson (DD-729), Collett (DD-730), and Henderson (DD-785), was tasked with a high-risk mission to support the Inchon Landing.

The tin cans were ordered to steam up the 30-mile-long, treacherous, and poorly charted Flying Fish (So Sudo) Channel at high tide to bombard enemy positions at Wolmi-do and the waterfront of Inchon. They did this among floating mines (the destroyers sank 12 mines), the 918th’s 76mm field guns, and strafing runs from enemy Yaks.

While the destroyers were supported by a four-ship cruiser force filled with 8- and 6-inch guns — USS Rochester (CA-124), Toledo, HMS  Jamaica (44), and HMS Kenya (14)— the deep draft cruisers could only go as far as Inchon’s outer harbor, some 14,000 yards offshore. All were provided with top cover by the planes of TF-77.

Derided as a “sitting duck” operation as it was to be done in daylight hours due to the tide pattern and in close proximity (within 800 yards) to shore (Collett, Gurke, and Swenson took hits from Korean 76mm batteries while De Haven got close enough to have received several .50 caliber hits but without serious damage), the destroyers nonetheless accomplished their mission and make it back out to sea before the tide plummeted and left them stranded on the mud.

As noted in the Marine Corps history of the landing:

It had been long since the Navy issued the historic order “Prepare to repel boarders!” But Admiral Higgins did not overlook the possibility of NKPA infantry swarming out over the mud flats to attack a disabled and grounded destroyer. And though he did not issue pikes and cutlasses, the crews of the Gurke, Henderson, Swanson, Collett, De Haven, and Mansfield were armed with grenades and Tommy guns for action at close quarters.

The total damage to the destroyers was structurally insignificant, however, and the combined casualties amounted to one man killed and eight wounded.

The force steamed back in on the 15th to land the Marines, following three squat LSMR rocket ships (No. 401, 403, and 404) that fired 1,000 of their fiery 5-inch bombardment salvos into the NKPA positions.

Soon, the destroyers were following up with everything they had. From L-minus 45 to L-minus 2, the four cruisers and six destroyers would dump no less than 2,845 8, 6, and 5-inch shells on Inchon and its outlying island, each ship concentrating on specifically assigned target areas.

From H-minus 180 to H-minus 5, the cruisers and destroyers were scheduled to blast their assigned targets with another 2,875 big gun shells, “smashing every landmark of tactical importance and starting fires that blazed across the whole waterfront.”

The Devil Dog-filled LCVPs and LSUs followed behind, covered by the 5-inch and 40mm fire from the destroyers. It was a resounding success, and by 0745, 3 bn/5th Marines radioed “Captured 45 prisoners. Meeting light resistance.”

The destroyers fired so many 5-inch shells in three days (1,700 on 13 September alone) that they needed to be re-barreled.

The six “Sitting Ducks” destroyers of TE 90.62 that gave such yeoman service at Inchon, De Haven included, earned a collective Navy Unit Commendation:

“For outstanding heroism in action against enemy aggressor forces in Korea from 13 to 15 September 1950. Skillfully navigating the extremely difficult and hazardous approaches to enemy-held Inchon in advance of the initial assault against that fortress, Task Element 90.62 coolly entered the strongly fortified harbor and anchored within close range of hostile gun positions. Defying the deadly barrage of heavy enemy shore-battery fire delivered from a myriad of hidden gun emplacements scattered along the coastline, the gallant destroyers of this Element courageously proceeded to launch an accurate and crushing fire attack in the first of a series of well planned and brilliantly executed bombardments which culminated in the reduction of the port’s defenses and in successful landing of friendly forces at Inchon on 15 September 1950. Although sustaining several casualties and numerous hits from the roaring enemy shore batteries, these ships repeatedly refused to leave their assigned stations and boldly continued to return the heavy counter-fire of hostile guns until their scheduled time of withdrawal. Fully aware that with each successive entry into the treacherous channel, the peril of meeting increased resistance was greatly intensified, they braved the hazards of a hostile mine field, passed dangerously close to the enemy’s shore fortifications, and unleashed a furious bombardment which eventually neutralized the port defenses sufficiently to permit the successful amphibious landings. An aggressive and intrepid fighting unit, the daring officers and men of Task Element 90.62 achieved a splendid combat record which attests the teamwork, courage, and skill of the entire Destroyer Element and enhances the finest traditions of the United States Naval Service.”

Moving past Inchon, on 26 September, De Haven used her guns to disperse a North Korean unit ambushing ROK troops before going to assist the sister destroyer USS Brush (DD-745), which had struck a mine. She escorted the damaged ship back to Sasebo, arriving on the 30th.

On 6/7 October, De Haven provided NGFS for a raid by British Royal Marines from 41 (Independent) Commando on enemy railway tunnels and bridges on the east coast of Korea. The Commandos blew the railway tunnel at Kyongsong Man, less than 20 miles south of Chongjin.

De Haven was ordered back to Yokosuka and Pearl Harbor for refit on 23 October, wrapping her first very hectic Korean tour.

By 12 July 1951, she was back on the gunline/blockade duty off Korea, which she maintained until 1 February 1952.

Her third Korean tour ran from October 1952, when she clocked in as the flagship for patrols in the Chongjin-Songjin-Chaho area, through 20 March 1953, the latter stint including exchanging gunfire with Chinese batteries while supporting minesweeping operations off Wonsan. In 16 days off Wonson, De Haven and her partner destroyer, USS Moore, observed the impact of 316 incoming Chinese shells, some as close as 400 yards, and provided counterbattery fire in return.

De Haven earned a Navy Unit Commendation and six battle stars for Korean War service, bringing her constellation to 11 stars with her WWII service included.

  • North Korean Aggression — 27 June – 12 September 1950, and 18 September – 23 October 1950
  • Inchon Landing — 13-17 September 1950
  • U.S. Summer-Fall Offensive — 18 July – 2 November 1951 and 3-27 November 1951
  • U.S. Summer-Fall Offensive — 28 November 1951 – 25 January 1952
  • Korean Defense, Summer-Fall 1952 — 21 October – 30 November 1952
  • Third Korean Winter — 26 January 1953 – 20 March 1953

Test bed and space support

By the early 1950s, the Navy had decided that 21-inch anti-ship torpedo tubes as well as 40mm and 20mm guns were obsolete, so conversions to the Sumners saw these deleted and replaced with six twin 3″/50 radar-controlled DP mounts and a Hedgehog ASW system.

Post-Korea, De Haven spent the next 15 years in a much more peaceful Pacific than she had known in her first decade of service as a permanently deployed Yokosuka-based destroyer. Between alternating fleet exercises, “hearts and minds” port calls, and West Pac deployments (making six voyages to the Far East from 1953 through 1959 alone), she also had some out-of-the-ordinary taskings.

In 1958, she served as an experimental vessel for the budding Rocket Assist Torpedo program, which would later become ASROC. The idea at the time was that the RATs would launch from a platform built into a destroyer’s stern twin 5″/38 gun house.

USS De Haven (DD 727) is shown with the Rocket Assist Torpedo (RAT) launching system installed on the aft five-inch gun mount. Released July 25, 1958. 330-PS-9056 (USN 710203)

Close-up view of the Rocket Assist Torpedo (RAT) launching system installed on board USS De Haven (DD 727). “An added weapon to the anti-submarine warfare forces, the rocket-assisted torpedo weapon system consists of a rocket-propelled anti-submarine torpedo 13 ½ feet in length and weighing 450 pounds. The missile is propelled through the air by a powerful rocket. The spent rocket drops away, and the torpedo continues on its way. It deploys a parachute, which stabilizes its flight and carries it down to the water. On entering the water, the torpedo releases the parachute, sheds its nose cap, and starts to search for and attack the submarine. Released July 25, 1958.” 330-PS-9056 (USN 710204)

Then came Operation Hardtack I, a series of nearly three dozen nuclear tests from 28 April to 18 August 1958 at the Marshall Islands testing grounds (Bikini Atoll, Enewetak Atoll, etc). Besides testing a variety of devices and delivery methods, Hardtack also tested how close Navy ships and aircraft could be to these “tactical nukes” and, following washdown procedures, still operate.

De Haven was on hand for 27 of 35 blasts, some as close as 5,900 yards away. The highest TLD badge reading on De Haven was 1.76 R. In that blast, Hardtack Wahoo, De Haven suffered the following damage:

Engineering Spaces–Personnel were generally calm, though they considered it violent. In some cases, personnel were frightened.

Lower Sound Room–The shockwave sounded like water rushing by the ship. A shock wave shook the ship violently with a loud cracking noise. Personnel were somewhat frightened.

Bos’n Locker– Ship vibrated violently, first fast, then slow. Sounded like water pouring into the ship. Personnel were considerably frightened

From the 476-page Hardtack case file, declassified in 1984, De Haven’s participation in the project:

The test footage from Hardtack was only cleared and released by Lawrence Livermore National Laboratory in 2017.

FRAM’d

In the early 1960s, the remaining Sumners were ordered converted under the Fleet Rehabilitation and Modernization II (FRAM II) program to make them more capable for Cold War threats. For these ships, most pushing 15 years on their hulls, it was an eight-month mid-life overhaul, with a $7 million per hull price tag.

Sumner class destroyer FRAM II profile, circa 1968. Click to big up

FRAM II included new radars (SPS-10 2D surface-search and SPS-40 long range air search), a fixed SQS-29 sonar dome on the keel under frame 25, which increased her depth by 6 feet, the installation of a Gyrodyne QH-50 DASH ASW drone system and hangar, and the addition of a winched SQA-8 variable depth sonar on her fantail.

Because the 369-foot Sumners did not have sufficient hull length, they did not receive the ASROC system, which was part of the more extensive FRAM I program that was applied to the longer (and slightly younger) 380-foot Gearing-class destroyers. Instead, they had to make do with two triple Mark 32 torpedo tubes for Mark 44 torpedoes and two single 21-inch tubes for Mark 37 torpedoes installed between the funnels. In exchange, they lost their legacy ASW gear (Hedgehog and depth charges) as well as their 3″/50 DP gun mounts.

On 1 February 1960, De Haven began her FRAM II modernization at San Francisco, which was completed in September.

Newly converted, De Haven left Long Beach on 3 October 1961 for a 985-day forward deployment to 7th Fleet at Yokosuka that saw her return to California 33 months later after steaming 213,576 miles. This included 325 days in Yokosuka, 18 port calls in seven other countries, five exercises (Red Wheel, Yellowbird, Big Dipper, Lone Eagle, and Mercury), four patrols along the line of contact between China and Taiwan, the ship’s first deployment to Vietnam providing support to ready amphibious assault force, an exotic five week tour as station ship Hong Kong, and working as a plane guard for 11 different carriers.

And that’s just the stuff that’s on the record.

In 1962, she was the first ship to take on the Navy’s DESOTO patrols. This was a response to the expanded claims on territorial waters made by China on Taiwan, a geopolitical dispute from the Cold War that is still relevant nowadays. Operating with a SIGINT team aboard under the classified and direct control of ComSeventhFleet, she earned the 197th, 198th, and 199th Serious Warnings from Red China over penetration of what Peking considered its territorial waters near the old German treaty port of Tsingtao. While eight later Desoto patrols took place along east and north China and up the/Korean coast as far as the Soviet. Gulf of Tartary, and then switched to the Gulf of Tonkin ala USS Maddox, the original code name was for “DEhaven Special Operations off TsingtaO.”

She also served on the NASA recovery squadron for Mercury-Atlas MA-9 (“Faith 7,” Major Gordon Cooper, USAF) in May 1963.

In July 1966, she was once again detailed to assist NASA as part of the Gemini-Titan 10 (GT-10) recovery crew, one of the secondary splashdown zone (No. 3, off Okinawa) vessels, should the spacecraft not make the primary recovery ship, the newly commissioned USS Guadalcanal (LPH-7). As it turned out, Guadalcanal easily recovered the record-setting Gemini X, the 16th crewed American flight, including Command Pilot, LCDR John W. Young, USN, and Pilot, Col. Michael Collins, USAF, as the capsule landed just 3 miles from the ‘phib, just off the Virginia coast.

After weeks of training to recover a splashdown space ship on a mock-up “boilerplate,” and with an Army commo sergeant and a NASA tech aboard, but Gemini X landing as planned on the other side of the globe, De Haven instead had a 1911 shoot-ex off the helicopter hangar and returned to port.

Vietnam

No destroyer based in the Pacific in the 1960s got out of deployments to Southeast Asia.

We know that De Haven went at least five times, including April-December 1963, October 1966- March 1967, April-August 1968, October 1969-March 1970, and November 1970- April 1971.

This included inland brown water service on the Mekong River in September 1963 and on the Saigon River during early March 1967, as noted by the VA Agent Orange list.

As noted by her Veterans page:

During this period of time, De Haven served as a naval gunfire support unit in I, II, III, and IV corps and Rung Sat special areas, firing over 22,000 rounds in support of these operations and other noteworthy campaigns, including direct combat engagement with North Vietnamese artillery units on multiple occasions. De Haven’s assignments included search and rescue, radar picket duty, electronic countermeasures, Snoopy Drone operations, shore bombardment, and attack carrier operations from both the “Yankee” and “Dixie” Station staging areas. De Haven participated in the rescue of four downed pilots off the coast of North Vietnam.

With the drawdown in Vietnam, De Haven was decommissioned and stricken on 3 December 1973, capping a very active 29-year career.

Back to Korea (under a different flag)

Transferred to the South Korean Navy two days after she was stricken from the NVR, De Haven was appropriately renamed ROKS Incheon (DD-98/918) and served under the flag of that country until 1993.

Epilogue

Little remains of our subject.

Her logs and plans are in the National Archives. 

The battered 48-star ensign that flew from her mast during Typhoon Cobra in 1945 is at the Maine Maritime Museum in Bath, Maine.

A plaque in the ship’s memory is at the Museum of the Pacific (Nimitz Museum) in Fredericksburg, Texas, dedicated by several veteran members of her crew. For the record, she suffered no casualties in WWII.

The USS DeHaven Sailors Association remembers both tin cans today and is very active on social media. 

Her first skipper, John Dimmick, retired in 1959 as a rear admiral after 21 years of service and later became a high school history teacher in Arizona for almost two decades. He passed in 1987 at age 80.

Of De Haven’s 19 other commanders, at least two others earned stars, including her CDR William Heald Groverman Jr. (USNA ’32), who stood on her bridge on VJ Day, and CDR James Ward Montgomery (USNA ’44), who was her skipper during most of the 985-day West Pac deployment in 1961-63. Of note, Groverman had earned two Silver Stars in destroyers before he came to De Haven and only retired in 1971 after 43 years in the Navy. He had characterized De Haven as having a “good record” and being “a proud ship” in her WWII War History. He seemed like a man who would have known. They passed in 2011 and 1997, respectively.

She is remembered in a variety of maritime art.

The winter monsoon in that region is characterized by consistent heavy clouds and rainfall that make operations difficult.” Framed Dimensions 52 1/2H X 64 1/2W. Accession #: 88-160-FI.

Finally, German scale model maker Wolfgang Wurm crafted a 1:192 diorama of De Haven in her 1945 livery at sea during Typhoon Cobra. It is on display on level 5 of the Internationales Maritimes Museum Hamburg.

The Navy, in its infinite wisdom, has not elected to name a third destroyer De Haven, which is a shame.

Its purpose is to provide information and a means of contact for those interested in warships.

With more than 50 years of scholarship, Warship International, the written tome of the INRO, has published hundreds of articles, most of which are unique in their sweep and subject.

PRINT still has its place. If you LOVE warships, you should belong.

Australia Goes $1.12B Hard in the Remote Minisub Paint

Posted on by Leave a comment

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.

Big Iron secures from the Persian Gulf Watch

The “Blackhawks” of Helicopter Mine Countermeasures (HM) Squadron Fifteen are steadily prepping to end their 38-year run as an RH-53A/D and MH-53E Sea Dragon squadron.

Its sister squadrons, “The World Famous Vanguard” of HM-14 and the reserve airborne mine countermeasures (AMCM) squadron, the “Golden Bears” of HM-19, were decommissioned in 2022 and 1994, respectively.

With the Sea Dragon slated to retire in FY27, ending the Navy’s AMCM program, which began in 1971 when 15 well-worn CH-53As were acquired from the Marines and rebuilt as RH-53As, the ‘Hawks have shut down “Big Iron,” Det II (DET2), the longstanding four-aircraft AMCM deployment to Bahrain. HM-14 established the first permanent forward-deployed AMCM detachment in Manama in 1999.

The last flight of Det II occurred on 31 August 2025.

It should also be pointed out that the first of four Bahrain-deployed Avenger-class mine countermeasures ships, USS Dextrous (MCM-13), was decommissioned this week as well. The other three will soon follow.

As for USN mine assets in the Gulf after that happens, where Iran has a huge arsenal of 5,000-6,000 sea mines (potentially including advanced EM-52 rocket-propelled, rising mines from China), well, there may be an LCS with a MCM Mission Package (“we promise they work”) or maybe an MH-60 with an Archerfish kit.

Maybe.

Mines Below, indeed.
