US Submarine Sinks Iranian Warship Off Sri Lanka Leaving Dozens Dead and Missing
A United States Navy submarine has sunk an Iranian warship in the Indian Ocean, killing at least 87 sailors and leaving more than 60 others missing, according to Sri Lankan and U.S. officials. The strike occurred about 40 kilometres south of the port city of Galle, significantly widening tensions between Washington and Tehran.
The vessel was identified as the IRIS Dena, a Moudge-class frigate operated by the Islamic Republic of Iran Navy. Authorities said the ship was returning from a multinational naval exercise in the region when it was struck by a torpedo fired from a U.S. submarine in international waters.
U.S. Defence Secretary Pete Hegseth confirmed the attack, describing it as the first time since World War II that a U.S. submarine has sunk an enemy warship using a torpedo. He said the action was aimed at countering Iranian naval capabilities amid escalating hostilities.
Sri Lanka’s navy launched an immediate search and rescue operation after receiving a distress call. Military vessels and aircraft were dispatched to the scene, where survivors were found clinging to debris and life rafts in challenging sea conditions.
At least 32 crew members were rescued alive and taken to hospital in Galle for treatment. Officials reported that 87 bodies had been recovered, while approximately 61 sailors remain unaccounted for as search efforts continue.
Sri Lankan authorities stressed that the country was not involved in the military action and had responded solely on humanitarian grounds. The government reiterated its neutral stance and commitment to international maritime law.
The sinking of the IRIS Dena represents a significant blow to Iran’s naval fleet. The frigate was among Tehran’s more modern surface combatants, equipped with missile systems and advanced radar capabilities.
The incident marks a sharp expansion of the U.S.–Iran confrontation beyond the Gulf region, raising concern among Indian Ocean states and global powers. Regional governments are closely monitoring developments amid fears of further escalation.
Tehran has yet to issue a detailed public response, though diplomatic channels between Iranian officials and Sri Lankan authorities remain active as families await news of the missing sailors.
Security analysts say the strike could prompt urgent discussions at the United Nations and among major powers, as questions mount over the strategic and legal implications of a naval engagement far from the traditional theatre of conflict.
