US submarine torpedoes Iranian frigate IRIS Dena off Sri Lanka — first torpedo attack on enemy warship since WWII; 87 killed, ~61 missing, 32 rescued

US submarine torpedoed the Iranian frigate IRIS Dena approximately 40 nautical miles off Galle, southern Sri Lanka. Defense Secretary Hegseth confirmed at Pentagon briefing, calling it ‘the first such attack on an enemy since World War II.’ The ship sent a distress call between 06:00-07:00 local (00:30-01:30 GMT). Sri Lankan authorities rescued 32 sailors and recovered bodies. Multiple sources report 87 killed, approximately 61 missing. This is the 18th+ Iranian naval vessel destroyed but the first outside the Persian Gulf/Hormuz theater — representing a major expansion of the naval war into the Indian Ocean. Highest-profile naval engagement since the Falklands War.
