Bonefish, found

Gato-class fleet boat USS Bonefish (SS-223) returning to the submarine base in Fremantle, Australia, at the end of her 4th war patrol on 30 May 1944

In company with her fellow fleet boats Tunny and Skate, USS Bonefish (SS-223), commanded by T/CDR Lawrence Lott “Larry” Edge (USNA ’35), departed Guam on 28 May 1945 to conduct her eighth war patrol. She is still on that patrol, and until last week her final resting place was known only to God, sunk by Japanese surface forces near Toyama Wan on or about 18 June.

Last week, Tiburon Subsea CEO Tim Taylor and the Lost 52 Project announced that the wreck of Bonefish had been discovered during surveys in 2025.

Beyond Bonefish, Tiburon’s current expedition located the lost Sumner-class destroyers USS Drexler (DD-741) and William D Porter (DD-579), and the Japanese merchant ship Konzan Maru.

Welcome Back, Big Maime!

The Navy commissioned the 25th Virginia-class fast-attack submarine USS Massachusetts (SSN 798) in a traditional ceremony held Saturday, 28 March, in Boston Harbor. Delivered to the Navy last November, she is the 6th commissioned warship on the Navy List to carry the name of the Commonwealth.

As the Navy welcomed its seventh Flight VI Virginia to the fleet, the crew of its oldest warship, the frigate USS Constitution (“Old Ironsides”), honored the moment by rendering a historic salute to her joining the fleet, complete with flintlocks and carronades.

“From wooden hulls and sail power to nuclear propulsion and advanced undersea warfare capabilities, this moment reflects the enduring strength, innovation, and readiness of the United States Navy.”

That’s one sleek Uber

Talk about historical twists. Just a couple of weeks away from the 86th anniversary of Unternehmen Weserübung, which saw the RN and Kriegsmarine face off in the Norwegian littoral dozens of times– with each taking a bruising over the nine-week campaign– we have this amazing photo essay released by NATO.

I give you the German Type 212A (U-31 class) SSK– 1. Ubootgeschwader’s U-35 (S 185)— dropping off Royal Marine Commandos in Norway to take part in the appropriately named Exercise Cold Response ’26 via inflatable. The RMs are from Shore Reconnaissance Troop and Special Observers from 148 Battery, both of which are from Surveillance and Reconnaissance Squadron (SRS), 30 Commando (IX Group).

Though small 1,500-ton, 183-foot boats, the Type 212As can carry a baker’s dozen advanced 21-inch torpedoes and have room for as many as eight Kampfschwimmers, but as seen above, RMs can work in a pinch.

SSNs still keeping the Pole nailed down

When not sniping wayward Iranian corvettes and launching TLAMs for CENTCOM, the 125-year-old U.S. Navy Submarine Service is busy this week atop the world.

The Arctic Submarine Laboratory’s Operation Ice Camp 2026 kicked off last week in the Arctic Circle as the legacy Virginia-class fast-attack submarines USS Santa Fe (SSN 763) and USS Delaware (SSN 791) performed a vertical surfacing to a very 1981’s The Thing kinda camp.

The camp, named “Boarfish,” gets its namesake from the WWII Balao-class fleet boat USS Boarfish (SS 327), which served as the flagship for Operation Blue Nose, the first-ever exploration under the polar ice cap. Of note, this year marks the 100th U.S. sub surfacing through Arctic ice at the North Pole, a tradition kicked off by USS Skate (SSN 578) in March 1959.

Skate cracking the ice back in the day

Just as the as-yet-to-be-identified SSN that sank the Iranian Dena last week carried three Royal Australian Navy personnel who are busy learning their trade on nuclear-powered hunter killers for AUKUS, Delaware is carrying a small team of RN submariners, while SUBPAC’s Santa Fe has a few more Ozzys.

“The three-week operation brings together U.S. forces and international partners to research, test, and evaluate operational capabilities in the challenging Arctic environment,” notes SUBLANT.

Clearing the air on Cold War torpedoing

With the news and dramatic IR footage of an unidentified American SSN/SSGN sending a single Cleveland-built MK 48 ADCAP into the Iranian frigate/corvette Dena on Wednesday, some 20 miles south of Galle in Sri Lanka, there have been lots of goofy comments floating around.

A couple of interesting historical tidbits include the fact that the last American warship in commission to have sunk an enemy ship in battle was “Old Ironsides,” the wooden-hulled frigate USS Constitution, a title she held since the Perry-class frigate USS Simpson was decommissioned in 2015. Simpson had, somewhat ironically, sunk an Iranian naval vessel during Praying Mantis in 1988.

The last American sub to chalk up confirmed torpedo “kills” in combat was the Tench-class fleet boat USS Torsk (SS-423) under T/Cdr. (later RADM) Bafford Edward “Loopy Lou” Lewellen, USNA ’31.

Using experimental 19-inch Mark 27 “Cutie” and 21-inch Westinghouse Mark 28 passive-acoustic electric torpedoes rather than his straight(ish) running steam-powered MK14-3As, Lewellen sank the Japanese coastal defense craft Kaibokan 13 and Kaibokan 47 on 14 August 1945 in the Sea of Japan while on her Second War Patrol. While the attacks were not covered in her Patrol Report, they are documented in her War History.

Later, setting a record of over 11,000 dives as a training boat, Torsk was decommissioned in 1964 and has been preserved as a museum ship in Baltimore since 1972.

“Kills” since then

There have been at least three confirmed anti-ship torpedo engagements (and conspiracy theories about  Cold War submarine losses) between Torsk and today.

In 2010, the South Korean Pohang-class corvette ROKS Cheonan split apart and sank while interdicting a mysterious underwater contact and, when raised, was found to have elements of a Nork CHT-02D torp in her wreckage.

On 2 May 1982, the RN Churchill-class hunter-killer HMS Conqueror (S48) torpedoed and sank the Argentine Brooklyn-class light cruiser ARA General Belgrano (C-4)— the highly decorated ex-WWII era USS Phoenix (CL-46). 

HMS Conqueror returns to Britain flying the Jolly Roger after sinking the Argentine cruiser Belgrano during the Falklands War. Pictured on 4 July 1982.

On 9 December 1971, the Pakistani Daphne-class SSK, PNS/M Hangor (S-131), torpedoed and sank the Indian Type 14 (Blackwood-class) frigate INS Khukri (F149).

It will be interesting to see which American sub returns to her homeport in the coming months with a Jolly Roger and broom tied to its masts.

Comte deGrasse runs again!

The future SNA De Grasse (S638), the fourth of six planned 5,200-ton Suffren-class (Barracuda type) SSN built for the French Navy, launched last May 2025 and began her first (Alpha) sea trials last week, with delivery to the Marine nationale expected later this year.

This is all very appropriate for the 250th anniversary of the events of 1776 here in the states as she carries the name of Lt. Gen (of Navy) François Joseph Paul, Comte de Grasse, Marquis of Grasse-Tilly, KM — best known for his crucial victory over the Royal Navy at the Battle of the Chesapeake in 1781 which sealed Cornwallis’s fate at Yorktown which in turn helped secure U.S. independence.

The French formerly celebrated De Grasse with an improved La Galissonnière class AAA cruiser in service from 1956 to 1973 and a Tourville-class frigate that served from 1975 through 2013.

Over here, we have also saluted the good Admiral de Grasse with a Great War-era patrol boat (ID-1217), a WWII Crater-class cargo ship (AP-164/AK-223), and the beautiful Pascagoula-built Sprucan USS Comte de Grasse (DD-974), which was active from 1978 to 1998.

The French and U.S. tin cans of the same name cruised together off Yorktown in 1981, on the Bicentennial of the Battle of the Chesapeake.

Nice to see the name return to the sea.

Perhaps the French will send the new De Grasse over here this year, or perhaps in 2031, the 250th of Chesapeake/Yorktown.

First ROK SSK retired at 34

Unlike many U.S. allies and Western fleets in general, which got into the submarine game post WWII, South Korea never operated surplus American fleet boats for a couple of decades, then upgraded to German SSKs– they just went German from the get-go.

South Korea’s first full-sized (not midget) submarine, ROKS Jang Bogo (SSK-61/SS-061), was recently decommissioned after nearly 34 years of service. A German HDW-made Type 209/1200 boat ordered on 12 August 1986, she was named for the 8th-century Korean admiral Chang Pogo. Launched in September 1991, she was commissioned in October 1992.

Most famously, Jang Bogo was reportedly never detected as a Red OPFOR boat during RIMPAC 2004, virtually firing 40 torpedoes, “sinking” 15 ships, including the super carrier USS John C. Stennis. A serious wakeup call to the USN when it came to ASW against a modern SSK.

Eight of her sisters, upgraded by Daewoo, continue in operation in ROKN service at least for now, carrying the locally-made and very advanced White Shark heavy torpedo and submarine-launched Hae Sung anti-ship missiles. They are being replaced by a licensed copy of the German Type 214, the KSS-II/Sohn Wonyil-class, AIP-equipped 1,800-ton boats, made by HII and Daewoo.

And with that, play us out, ROKN:

Penny Wise and Pound Foolish, 688 edition

The Los Angeles (SSN-688) class submarine is a thing of joy.

Sixty-two mother beautiful 7,000-ton 30-ish knot hunter killers that can carry a mixture of 37 torpedo/TLAM/Harpoon/Mines in their hull, with the latter half also having 12 VLS cells for a little added “room to boom.”

They were a big reason that, when coupled with the older Sturgeon-class “fish boats,” the Navy had 83 SSNs on the list in 1995, a fleet likely never surpassed in human history in terms of cutting-edge hunter killers.

Designed to run 30+ years with a midlife Refueling and Complex Overhaul (RCOH) that can take 2-4 years, done at about the 15-19 year mark, the 688s have a very long life planned. The preceding Sturgeons followed a shorter lifecycle, sans refueling but with a less comprehensive mid-life overhaul, but most still served 25 or more years in commission.

However, in the interest of saving a buck or billion, between 1995 and 2008, the Navy elected to lay up 11 of these dedicated underwater Swiss army knives at their midlife point, sending Los Angeles class sisters USS Baton Rouge, Omaha, Cincinnati, Groton, Birmingham, New York City, Indianapolis, Phoenix, Boston, Baltimore, and Atlanta to recycling after just 15 or so years in operation rather than springing for a RCOH. Another six boats (USS Portsmouth, Minneapolis-St. Paul, Rickover, Augusta, Honolulu, and Salt Lake City) inside the same period were retired in their early 20s–a full decade early– due to their previously planned RCOH cancelled.

So 17 of 62, just over one-quarter of the class, were given the pink slip while there was still work to be done. That works out to 225~ planned submarine years that just evaporated, and that is a lowball estimate. These were 225 years that were already promised by previous SECNAVs and CNOs, Congresses, and Presidents. On hulls that were already paid for by the taxpayers.

This left those 688s still on the payroll to work longer and harder. The two most recently decommissioned, USS Key West (SSN-722) and Helena (SSN-725), were in commission just over 38 years.

Sure, sure, you can argue that the billions saved by scrapping 17 gently used SSNs helped make the current 26 Virginia-class subs (which started construction in 2000) more affordable, but that program buildout is running behind schedule, and, counting both the 688s that were commissioned early and those that weren’t, 36 Los Angeles-class boats have been retired.

Today, the Navy just has 50-52 SSNs in service, with the force skewing to slightly more Virginias (24 commissioned, two delivered pending commissioning), followed by 23 remaining 688s, and three super secret duty Seawolves. This is expected to decline to around 40 or so as the 688s are being retired faster than the Viginias are being built (and Australia also wants some SSNs of their own)

Thus, you see the shortfall in SSN hulls available.

But wait, the Navy has pulled a tiny rabbit out of the hat by extending the service life of up to five Los Angeles SSNs to help mitigate the gap.

To that aim, USS Cheyenne (SSN 773), a Block III 688i and the last Los Angeles-class boat commissioned in 1996, last week completed its Engineered Refueling Overhaul availability as the first submarine to undergo an overhaul as part of the Service Life Extension Program — extending her total service life beyond 44 years.

The Cheyenne Project Team, encompassing various trade workers, engineers, and material support personnel at PNSY, worked alongside the ship’s crew to return Cheyenne back to the fleet as a battle-ready Navy asset — an achievement that advances the effort to close the gap in ready attack submarines. This milestone ensures the U.S. Submarine Force remains the most lethal, capable, and feared combat force in the world.

Make it make sense that the same Navy that killed 15-year-old members of Cheyenne’s class now wants her to keep prowling well past her 40s.

Different times and suffering from different crimes, I suppose.

Le Tonnant Found

The lost Redoubtable (Pascal)-class submarine of the M6 series (Agosta type) Le Tonnant (“Thunderer”) (Q172) has been discovered.

Built by F.&Ch de la Méditerranée and commissioned on 1 June 1937, she made a high-profile pre-war deployment to Indochina, participated in some early war patrols with the Toulon-based 3rd Submarine Squadron before the Fall of France in June 1940, and ventured as far as Dakar.

She then sailed under orders from Vichy until 15 November 1942, when she was scuttled off Cadiz, Spain, by her own crew following the German occupation of Southern France and the British-American occupation of French North Africa.

Her crew all managed to reach Spain and be interned for the duration, while Le Tonnant settled into the seabed.

Of Le Tonnant’s 31-boat class, only five survived the war, including the famous Casabianca (Q183).

Now, 83 years later, her wreck has been documented by a Franco-Spanish research team by the Univesite de Bretagne Occidentale.

 

Third Battlewagon SSN this Year

The U.S. Navy accepted delivery of the Submarine Force’s newest hunter-killer, the future USS Idaho (SSN 799), from Electric Boat on 15 December.

And with that, the Navy List is looking very 1944ish.

Idaho is the 26th Virginia-class submarine co-produced by EB and HII-Newport News Shipbuilding through a long-standing teaming arrangement. It is the 14th delivered by EB and is the eighth of 10 Block IV-configured attack submarines.

The future USS Idaho is the fifth Navy ship to be named for the state of Idaho. The first was a wooden-hulled storeship commissioned in 1866. The last was Battleship No. 42, which was commissioned in 1919 and received seven battle stars for service in World War II, then ignobly sold for scrap in 1947.

She joins the fifth (completed) U.S. Navy vessel named for the Bay State, the future USS Massachusetts (SSN 798), which was delivered to the service from Newport News on 21 November.

The last and most famous to carry the name thus far (BB-59) was commissioned in 1942 as a South Dakota-class fast battleship, earning 11 battle stars for exceptional service in WWII from Casablanca to Okinawa before being decommissioned in 1947. She remained in the Reserve Fleet until stricken from the Naval Vessel Register in June 1962 and continues to serve as a floating museum.

While Idaho and Massachusetts are set to be commissioned in 2026, the current USS Iowa (SSN 797) was commissioned in April.

The last Iowa, the famed class-leading fast battleship BB-61, which was christened on 27 August 1942, was only stricken from the NVR on 17 March 2006 and endures as a floating museum at Los Angeles, the only West Coast battlewagon.
