In a significant naval escalation, a United States submarine has sunk an Iranian warship during a military operation in the Indian Ocean. The incident occurred in international waters off the southern coast of Sri Lanka, marking the first torpedo sinking of an enemy vessel by U.S. forces since World War II.
U.S. Defense Secretary Pete Hegseth confirmed the engagement during a Pentagon briefing on Wednesday, stating, “An American submarine sunk an Iranian warship that thought it was safe in international waters. Instead, it was sunk by a torpedo.”
The targeted vessel was identified as the IRIS Dena, a Soleimani-class frigate of the Iranian navy. According to Sri Lankan officials, the attack resulted in substantial casualties. Sri Lanka’s Deputy Minister of Foreign Affairs Arun Hemachandra reported that at least 80 crew members aboard the Iranian frigate were killed in the sinking.
The incident represents a dramatic escalation in ongoing military operations between the United States and Iran. U.S. Central Command (CENTCOM) disclosed that American forces have now struck or sunk more than 20 Iranian vessels since joint U.S.-Israel military operations against Iran commenced on Saturday morning.
Notably, the IRIS Dena had recently participated in multinational naval exercises held in the Bay of Bengal from February 18-25, according to official exercise documentation. The sinking has raised concerns about further regional instability and potential impacts on crucial shipping lanes in the Indian Ocean.
Recovery operations are underway, with photographs showing bodies of Iranian sailors being transported to the mortuary at Karapitiya Hospital in Galle, Sri Lanka, highlighting the human cost of the confrontation.
