The Sinking of IRIS Dena: A Naval Strike That Escalated a Global Conflict
On 4 March 2026, a dramatic naval incident in the Indian Ocean drew global attention when the Iranian warship IRIS Dena was sunk by a U.S. Navy submarine off the southern coast of Sri Lanka. The strike killed dozens of sailors and marked the first time since World War II that an American submarine destroyed an enemy ship with a torpedo.
The event immediately intensified tensions in an already expanding conflict involving the United States, Israel, and Iran.
