This story has been updated with additional information from U.S. Central Command about the sinking of an IRGCN corvette. An American attack submarine sank an Iranian Navy ship off the coast of Sri Lanka,

According to Hegseth, one of the most significant milestones of the campaign was the complete destruction of an Iranian warship, which was taken out by an underwater torpedo.

The Iranian warship that was sunk in the Indian Ocean likely didn’t have the technology needed to defend itself against submarines.

US Secretary of Defense Pete Hegseth said Wednesday that a US submarine sank an Iranian warship in international waters after Sri Lanka’s Navy said it rescued more than two dozen people from an Iranian vessel that was sunk off its shoreline.

Videos released by the Pentagon on Wednesday captured the moment a U.S. attack submarine sank an Iranian warship in international waters.
