A United States Navy submarine sunk an Iranian ship with a single torpedo as the frigate was transiting the Indian Ocean, marking the first such kill by a U.S. submarine since World War II, the Pentagon confirmed on Wednesday.

Defense Secretary Pete Hegseth confirmed the strike during a Pentagon press briefing on Operation Epic Fury alongside Chairman of the Joint Chiefs of Staff Gen. Dan Caine.

“Yesterday, in the Indian Ocean ... an American submarine sunk an Iranian warship that thought it was safe in international waters,” Hegseth said. “Instead, it was sunk by a torpedo. Quiet death. The first sinking of an enemy ship by a torpedo since World War II.”

For those who nerd out on this stuff... modern torpedoes don't strike the hull. They detonate under the ship causing a large gas pocket under the ship which breaks the keel of the ship
