A U.S. submarine torpedoed and sank an Iranian warship in the Indian Ocean on Tuesday, according to Pentagon officials. The attack represents the first time the U.S. Navy has destroyed a warship with a torpedo since World War II.

The incident occurred in international waters off the coast of Sri Lanka. The U.S. military has released video footage showing the torpedo strike on the Iranian naval vessel. Defense Secretary Pete Hegseth confirmed the sinking of the Iranian warship.

Sri Lankan naval authorities report that approximately 140 people are feared missing following the sinking of the military vessel off the country's southern coast. The status and fate of the Iranian crew members remains unclear.

The attack marks a significant escalation in tensions between the United States and Iran. The incident expands the geographic scope of U.S.-Iranian military confrontations beyond traditional theaters of conflict in the Middle East to the Indian Ocean region.

This represents the first use of submarine-launched torpedoes by U.S. forces to sink an enemy warship in over 80 years, highlighting the historic nature of Tuesday's naval engagement. The Pentagon has not released additional details about the circumstances that led to the attack or the specific type of Iranian vessel that was sunk.
