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.

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 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” 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.

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:

Launching of USS DeHaven DD-727, January 9, 1944 via Maine Maritime Museum D_DE_031
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.

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.
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.
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.

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.

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.

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.
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.
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.

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.

The International Naval Research Organization is a non-profit corporation dedicated to the encouragement of the study of naval vessels and their histories, principally in the era of iron and steel warships (about 1860 to date). 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.

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.

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.

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.

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.

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

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.
Ogasawara Maru
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.
Shinko Maru No. 2, post torpedo hit
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.

Warship Wednesday, August 13, 2025: A Long-Lived Tyne Built Ship
Photo: Naval History and Heritage Command NH 58988
Above, we see the fine Armstrong-built Asama-class armored cruiser Tokiwaof the Imperial Japanese Navy photographed in 1899 with a bone in her teeth.
Amazingly, this indomitable warship would serve nearly a half-century and be lost during her fifth war for the emperor, some 80 years ago this week.
The Asamas
The late 19th/early century Imperial Japanese Navy was very European in construction. Ten out of ten battlewagons carrying the Rising Sun flag against the Russians in 1904 were built in the yards of Mr. Armstrong and Mr. Vickers in Britain.
Of the Emperor’s armored cruisers, Izumo and her sister Iwate came from Armstrong, Yakumo hailed from the German yard of AG Vulcan, Kasuga and Nisshin from Ansaldo in Genoa, and Azuma from Ateliers et Chantiers de la Loire in France. Ordered in 1897 alongside these six cruisers were another pair based on an improved design of the Chilean O’Higgins.
The Chilean armored cruiser O’Higgins was built in 1896-98 at Armstrong to the design of Sir Philip Watts for £700,000. The 8,500-ton 412-foot long three-piper could make 21.6 knots on a 30-boiler (16,250 ihp) plant and carried four 8″/40s and 10 6″/40s. She had a Harvey nickel steel armor belt that ranged from 5 to 7 inches, while her conning tower was protected with 8. She remained in Chilean service until 1933.
Sir Philip tweaked the one-off O’Higgins design to add more armor protection (2,100 tons all told) and horsepower to carry it all. Instead of a belt that maxed out at seven inches and the eight-inch CT, this new design rocked as much as 14 inches. It also used extensive compartmentalization with 163 watertight compartments, 32 of which were in the double bottom. This added 1,200 tons to the displacement and stretched the hull to 442 feet. The powerplant dropped the forest of 30 boilers seen on the Chilean ship for a dozen larger single-side cylindrical boilers and upped the ihp to 18,000 to keep the same (or better) speed.
Paid for out of a Chinese indemnity given to Japan as part of the spoils of the 1895 war, these two ships would be named Asama and Tokiwa, after traditional regions in the Empire.
The weaponry would also be stepped up a bit from O’Higgins.
While the Chilean ship carried four EOC 8″/40 Pattern T guns in single mounts, the new Asamas would carry two pairs of improved EOC 8″/45 Pattern U (41st Year Type in Japanese service) guns, the same type which would go on to be carried by the rest of Japan’s armored cruisers as well as the post Russo-Japanese War domestically built Ibuki-class armored cruisers. These were protected by six inches of armor over their gun houses and were serviced by electric hoists from the magazines.

The secondaries on the Asamas were also beefed up, from the 10 6″/40 QF EOCs on O’Higgins in five-inch turrets and casemates to 14 guns with 10 in casemates and four in single shielded mounts. Tertiary anti-boat armament included a dozen 3″/40 Armstrongs and seven 47/30 2.5-pounder Hotchkiss (Yamauchi) guns. Torpedo batteries included a 450mm tube in the bow and four on the beam. Likewise, two of her steam punts could be equipped with spar torpedoes.

Meet Tokiwa
Laid down on 6 January 1898 at Elswick as Yard No. 662/armored cruiser No. 4 (her sister Asama was No. 661), Tokiwa took to the water on 6 July 1898 and was commissioned on 19 May 1899. She made a mean 23 knots on her speed trials.

On 19 May 1899, with Captain (later Admiral) Dewa Shigeto in command, Tokiwa left Britain for Yokosuka, completing the 11,000nm voyage in a handy 57 days– a heck of a shakedown cruise.
IJN Tokiwa Navy and Army Illustrated Feb. 10 1900
War (with China)!
Rated as a first-class cruiser, Tokiwa was dispatched on 19 June 1900 to join the Eight-Nation Alliance naval forces in Chinese waters during the Boxer Rebellion. While arriving around the time of the assault against the Taku Forts, she was not used in the assault there, standing by offshore with a dozen other large, allied vessels as smaller gunboats closed in for the work.
However, landing forces from the Japanese ships sent 329 armed sailors ashore to help storm and garrison the forts.
While 54 Japanese marines were dispatched as part of Admiral Seymour’s overland relief expedition to Peking, I can’t say whether any of those came from Tokiwa.

Tokiwa returned to Kure on 20 August.
War (with Russia)!
Clustered with the armored cruisers Izumo, Iwate, Azuma, Yakumo, and Asama, along with the dispatch boat Chihaya, Tokiwa formed the 2nd Squadron under VADM Kamimura in 1903. This force proved a key left hook to the right cross of Togo’s 1st Squadron during the war against the Tsar.
Captain Shigetaro Yoshimatsu became Tokiwa’s eighth skipper on 19 January 1904. A professional officer who graduated from the Naval Academy in 1880, he had studied in France and England and fought as a gunnery officer on the second-class cruiser Yoshino during the 1894 war with China. He had been XO on Tokiwa’s sister Asama when she took part in the 1902 Spithead naval review celebrating the coronation of King Edward VII.

Three Meiji-era armored cruisers at work. Iwate (left), Tokiwa (center), and Yakumo (right), from the 2nd Fleet during the late Russo-Japanese War. Of note, the 9,500-ton Yakumo was the only large German-built warship in the Japanese Navy, delivered in 1900 by AG Vulcan Stettin. Both Iwate and Tokiwa were built at Armstrong on the Tyne.
Offshore for the initial torpedo boat attack on the sleeping Russian anchorage at Port Arthur on 8 February 1904, she managed a few 8-inch shells lofted when the Russians sortied out the following morning, and thus began the blockade and later siege of that fortress city that would prove the hub on which the conflict revolved.
IJN Tokiwa in 1904
It was off that port that Tokiwa almost captured the Russian destroyer Steregushchiy in March and participated in rebuffing Marakov’s 13 April sortie that ended in his death upon the sinking of his flagship via mines.

Relieved from the Port Arthur blockade in the summer 1904 to chase down a raiding trio of Russian armored cruisers (Rossia, Gromoboi, and Rurik) out of Vladivostok, Tokiwa, along with the armored cruisers Iwate, Izumo, and Azuma and protected cruisers Takachiho and Naniwa, finally clashed with the Russian cruisers off Ulsan on the early morning of 14 August. With the Russians outnumbered six hulls to three, the six-hour swirling artillery duel turned brutal, and Rurik was sunk, taking some 200 of her crew with her, while the severely damaged Rossia and Gromoboi managed to limp away.
Tokiwa landed some blows against Rossia and was slightly damaged by return fire, with three of her crew injured.

Then, following the collapse of Port Arthur, came the Valkyrie ride of VADM Rozhestvensky’s 2nd Pacific (1st Baltic) Squadron through the straits of Tsushima. Tokiwa was there.

During the battle, Tokiwa and her squadron engaged the Russians several times, most notably in the destruction of the 14,000-ton Peresvet-class battleship Oslyabya.

When the smoke cleared, Tokiwa had suffered eight hits, mostly from smaller caliber shells, resulting in 15 casualties.
Post-war, she was a darling of the fleet, being chosen to escort Crown Prince Yoshihito (later Emperor Taisho) on his tour of Yamaguchi and Tokushima Prefectures in 1908.

The same year, she participated in the 1908 Kobe Fleet Review.

In 1910, both Asama and Tokiwa had their well-worn set of British boilers replaced with 16 more efficient 16 Miyabara boilers as part of a general mid-life refit.
War (with the Kaiser)!
When the Great War kicked off, British-allied Japan soon got involved in the rush to capture (and keep) Germany’s overseas colonies. As part of this, on 18 August 1914, she was assigned to the 4th Squadron along with Iwate and Yakumo, part of VADM Sadakichi Kato’s 2nd Fleet, detailed to blockade and seize the German treaty port of Tsingtao, an operation that began on the 27th of that month and stretched into early November.

She was then dispatched to scour the West Pacific– along with other allied assets– in the attempt to run down Graf Spee’s East Asiatic Squadron. Once Spee was sent to the bottom along with most of his squadron in December and the last of his cruisers (SMS Dresdenand the Hilfkruezer Prinz Eitel Friederich) were accounted for the following March 1915, the pressure eased and our aging cruiser was allowed to spend the rest of the war in a series of more pedestrian tasks, including a series of Grand Maneuvers.

She became active in a series of globetrotting training cruises, carrying naval academy cadets. This included the 44th class cadet training cruise to the U.S. with Yakumo from 5 April to 17 August 1917. A second cadet training cruise for the 46th class with Azuma from 1 March to 26 July 1919 jogged south to Australia. Azuma and Tokiwa teamed up for a third cruise with the 47th class that roamed to the Mediterranean from 24 November 1919-20 May 1920.

Treaty rebuild
By 1921, both Asama and her sister Tokiwa, too slow for fleet operations, were reclassified as coast defense vessels. At the same time, many of Japan’s old armored cruisers were disarmed as part of the Naval Limitation Treaties, and their weapons were reduced.
The 8″/45s removed from Tokiwa and her fellow armored cruisers in the 1920s were recycled for use as coastal artillery, including two twin turrets at Tokyo Bay, four single guns mounted at Tarawa, and another four at Wake Island.
Between 30 September 1922 and 31 March 1923, Tokiwa was converted to a cruiser minelayer. In this, she landed her rear 8″/45 turret, her torpedo tubes, six of her 6″/40s, and all her obsolete 3-inch and 2.5-pounders. She then picked up accommodation for 300 mines on deck tracks for over stern sowing. A similar conversion was done to the old armored cruiser Aso (ex-Russian Bayan).
It was in this mine role that, on 1 August 1927, while training with mines in Saeki Bay, Kyushu, after returning from overseas service in China during the Shandong Intervention, Tokiwa suffered from an explosion that left 35 dead and another 65 injured. Through a combination of magazine flooding and assistance from nearby vessels, a complete disaster was avoided, and she was quickly repaired and returned to service.
The incident led to the redesign of the No. 5 Kai-1 mine to install safety features and a further redesign of several classes of new Japanese light and heavy cruisers to better handle damage.

War (with China, again)!
Once repaired, Tokiwa spent most of the next decade in Chinese waters and frequently landed her sailors and marines for strongarmed use ashore, especially after the Japanese invasion of Manchuria in 1931.

She returned home in 1937 to have her 16 Miyabara boilers, which had been installed in 1910, replaced by 8 Kampon boilers, reducing her speed to 16 knots. During this refit, she hung up the pretext of being a cruiser, and remaining 8″/40s and 6″/40s were removed. This allowed for her mine storage to be bumped to 500 “eggs”, and she had a couple of 40mm and 10 twin 25mm AAA guns installed. Likewise, by this time, her sister Asama had been converted into a training ship.
Tokiwa was on hand in Yokohama Bay with 98 other IJN ships in October 1940 for the largest (and last) grand fleet review in Japanese history.

War (with the Allies)!
On 29 November 1941, Tokiwa sailed from Truk as part of Operation “GI,” the invasion of the British Gilbert Islands, which began on 8 December (Japan time).
The following January, Tokiwa was part of Operation “R,” -the Invasions of Rabaul, New Britain, and Kavieng.
She felt her first Allied sting in a carrier raid at Kwajalein in February from USS Enterprise. Damaged in four near misses from 500-pound bombs, she suffered eight killed and 15 wounded. This sent her to Sasebo for three months of repairs.
Dispatched to respond to the Marine Raiders’ sweep of Makin Island in August 1942, she managed to pull quieter duty for (most of) the rest of the war, narrowly avoiding torpedoes from USS Salmon (SS-182) in 1943 on her way back to the Home Islands. There, she led a minelaying squadron (the 18th Sentai) that sowed over 6,000 mines.
Striking a mine off the Hesaki lighthouse in the Kanmon Strait in April 1945, Tokiwa put into Sasebo again for repairs and added another 10 25mm guns, giving her a final fit of 30 of these weapons (some reports state 37). She also had depth charge racks and throwers installed along with a Type 3 sonar and was fitted with primitive (2-shiki 2-go and 3-shiki 1-go) radars.
After laying minefields in her old 1905 stomping grounds in the Tsushima Strait, she was ironically damaged by a B-29-sown aerial mine on 3 June 1945 off Maizuru harbor. The damage was slight, and she left Maizuru after makeshift repairs for Ominato. In all, between 24 January 1944 and 30 June 1945, she laid 17 series of anti-submarine minefields in Japanese waters.
Five elderly (and mostly disarmed) Russo-Japanese war era cruisers were still afloat in Japanese home waters in the last days of the war: the everlasting sisters Asama and Tokiwa, along with Yakumo, Izumo, and Iwate. All were pummeled by American and British carrier-borne aircraft strikes in late July and early August 1945, with three of the five damaged so extensively they bottomed out in shallow water.

It was at Ominato that Tokiwa was caught by aircraft from USS Essex and Randolph on the afternoon of 9 August. She suffered at least four direct bomb hits and at least that many near misses, crippling the ship and killing or wounding half of her crew. Towed to shallow water off Cape Ashizaki, she was beached, and her crew attempted repairs.
With the end of hostilities, her crew was relieved on 20 September, and she was removed from the Naval List on 30 November.
All these battered old bruisers were unceremoniously scrapped shortly after the war, and only one, Tsushima veteran Yakumo, ever sailed again under her own power– as an unarmed repatriation transport to bring 9,000 Japanese troops home from KMT-occupied Formosa in 1946.

Epilogue
Today, there are few remains of Tokiwa despite her nearly 50 years (okay, 46 years, 11 months, 17 days) of service.
She is remembered in a variety of scale models
Between 3 October 1898 and 20 September 1945, she had 52 skippers. At least seven of these became admirals.
These included her Russo-Japanese War skipper, Capt. Shigetaro Yoshimatsu, who went on to become a full admiral and the sixth commander of the Combined Fleet (Rengo Kantaishireichokan) in November 1915, a post he held through October 1917.
Shigetaro Yoshimatsu, seen as the skipper of Tokiwa in 1904 and then as Admiral of the Navy in 1915. He passed in 1935, at age 75, having spent 37 of those years in uniform.
Another was Naoma Taniguchi, who, after serving as Tokiwa’s skipper in 1916-17, rose to become a full admiral and commander of the Combined Fleet, then Chief of the Naval General Staff in the early 1930s. Head of one of the IJN’s more rational factions, he was instrumental in the ratification of the Treaty of London and later refused to send ships to respond to the Manchurian Incident. For this, he and his deputy officers were forced into retirement in 1933, leaving more hawkish officers in charge. He passed soon after.
Then there was the Viscount Ogasawara, who translated Mahan into Japanese in 1899, served as Togo’s aide, and wrote several popular works on the Russo-Japanese war at sea, one of which was turned into a movie in 1930. Ogasawara later served as the director of the school that educated then Crown Prince Hirohito and, moving to the retired list in 1921 as a vice admiral, became a naval advisor to the throne through November 1945.
VADM Viscount Naganari Ogasawara was Togo’s aide and Hirohito’s teacher and advisor, taking a break between the two to command Tokiwa in 1912. He passed in 1958, aged 90, having spent 56 years in service. He was one of the last surviving Tsushima vets.
In 1989, the Japanese government recycled the name of the old cruiser for a new Towada-class replenishment ship (AOE-423). The Hitachi SC built vessel almost immediately clocked in on one of modern Japan’s first overseas naval deployments– Desert Shield/Storm, now some 35 years in the rearview. The oiler delivered non-combatant material to Saudi Arabia as part of Japan’s contribution to the coalition effort and has been a familiar consort to allied vessels underway in the WestPac in the past few decades.

Some 80 years ago today, on 26 July 1945, the humble 255-foot Algerine-class minesweeper HMS Vestal (J215) earned two unenviable distinctions.
As part of Operation Livery, while about 55 nautical miles south-west of Phuket, Siam, clearing enemy minefields as part of Force 63, she was hit by a Japanese kamikaze aircraft that killed 14 of her 130-member crew and left her too damaged for economical repair. That afternoon, in 72 meters of water and unmanned, she was finished by gunfire from R-class destroyer HMS Racehorse (H 11).

This made Vestal the sole British ship to be sunk by a kamikaze attack and the final Royal Navy ship to be lost in the Second World War. Further, the clearing operation by Force 63, which returned to Ceylon after Vestal’s loss, was the last offensive operation by ships of the British Eastern Fleet.
The 5th Fleet has kept four 224-foot Avenger-class mine countermeasures ships forward deployed on the line in Manama, Bahrain, since the late 1990s. Now, their 25+ year watch is ending.
USS Dextrous (MCM-13), which has been in the Persian Gulf since August 1997, has just received word that she will decommission on 3 September, wrapping up her career just four months past her 31st birthday, which is relatively old for any warship, especially one of fiberglass/wood composite construction.
“Dex” recently sailed in formation with the other three Bahrain-based Avengers– USS Sentry (MCM-3), Devastator (MCM-6), and Gladiator (MCM-11), and they look great.
The motto of the Dextrous is ” No One Goes Before Us.”
Once the last of the Avengers leaves the fleet in 2027– just two short years from now– the Navy will not have a single dedicated minesweeper for the first time since USS Lapwing (AM-1) was commissioned in 1918.
Probably a mistake.
Likewise, the fleet’s final dedicated HM (Helicopter Mine Countermeasures) Squadron, the “Blackhawks” of HM-15, will say goodbye to their beloved MH-53E Sea Dragons in 2027, and the final “Dragon Drivers” were minted last November.
The service’s 20~ operational MH-53E Sea Dragons, four of which are forward deployed to Bahrain, will leave the fleet in FY27.
The Navy earlier this year said it has four Mine Countermeasures (MCM) Mission Package (MP) sets “supporting LCS deployments in the 5th Fleet Area of Responsibility (AOR) and follow-on MCM MPs will support 7th Fleet operations by the end of FY 2027.”
