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).

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.
