U.S. Submarine Sinks Iranian Warship Amid Regional Tensions; Historical Claims Reviewed

On March 3, a U.S. Navy submarine sank an Iranian warship in the Indian Ocean using a torpedo, resulting in at least 100 casualties. U.S. Defense Secretary Pete Hegseth described this as the first submarine torpedo kill since World War II. However, fact checks note that similar submarine sinkings occurred post-WWII, including during the Falklands and Indo-Pak wars. The strike reflects heightened tensions in the region amid ongoing conflicts.
