WPTV Anchor and Navy Veteran Mike Trim is listening to the local submarine veteran community after the first U.S. torpedo sinking since World War Two

The Pentagon has not said which American submarine fired the torpedo, except to say it was a fast-attack submarine.

The Torsk's sinking of the Japanese vessel marked the last U.S. submarine kill for over eight decades - that is until March 3, 2026.

"It’s almost certain that Electric Boat contributed to its manufacturing in whole or in part,” Sen. Richard Blumenthal.

Secretary of Defense Pete Hegseth called the sinking of an Iranian warship with a single Mk48 torpedo a "quiet death."

An unidentified US submarine torpedoed and sunk the IRIS Dena, an Iranian Navy frigate, off the coast of Sri Lanka on Tuesday.

Since 1991, Navy subs have launched scores of cruise missiles in combat, but the torpedo attack off Sri Lanka is a return to form after 80 years.

The reported sinking of an Iranian warship by the United States off the coast of Sri Lanka has revived memories of one of the most dramatic naval episodes in South Asian history-the destruction of PNS Ghazi during the Indo-Pakistani War of 1971.
