U.S. forces under President Trump may have decisively sunk an Iranian frigate in international waters, signaling America’s renewed strength against global threats from Tehran.

Story Highlights

  • Sri Lankan Navy recovered 87 Iranian bodies from the sunk IRIS Dena frigate off Galle coast, with 32 wounded sailors rescued from 180 crew.
  • U.S. Defense Secretary Pete Hegseth claims a U.S. submarine used MK-48 torpedo to sink the vessel, expanding operations against Iran’s navy.
  • Sri Lankan officials treat it as an accident and reject submarine attack claims, amid conflicting reports of 101 missing sailors.
  • IRIS Dena, a Moudge-class frigate, was returning from MILAN 2026 exercises in India when it sank in Indo-Pacific waters.

Rescue Operation Details

Sri Lankan Navy launched immediate rescue efforts after the Iranian frigate IRIS Dena issued a distress call early Wednesday morning, 40 kilometers south of Galle in international waters. Navy vessels and aircraft responded swiftly, rescuing 32 critically wounded sailors. These crew members received treatment at Karapitiya Hospital, with one in critical condition and seven under emergency care. Foreign Minister Vijitha Herath confirmed 180 personnel aboard the Moudge-class vessel serving Iran’s Southern Fleet.

Conflicting Claims on Sinking Cause

Sri Lankan Navy spokesman Buddhika Sampath stated the incident remains an accident occurring beyond Sri Lankan waters. He rejected reports of a foreign submarine attack. In contrast, U.S. Defense Secretary Pete Hegseth announced a U.S. submarine sank the warship off Sri Lanka’s coast. One report details a U.S. attack submarine deploying an MK-48 heavyweight torpedo, marking the conflict’s extension to the 7th Fleet area.

Local outlets cited defense sources claiming a foreign submarine attack, reporting 101 sailors missing and 78 wounded. Sri Lankan forces found several dead bodies near the site. This frigate had just participated in the MILAN 2026 multinational exercise in Visakhapatnam, India, before heading home.

Casualty Toll and Ongoing Search

Latest updates indicate Sri Lanka recovered 87 bodies from the sea where the Iranian warship sank, highlighting the disaster’s scale. Initial figures noted 32 rescued, but higher casualties emerged with 101 missing per some reports. Search operations continue, though survivor prospects dim. The wounded receive care at Galle facilities for injuries from the sinking.

This event underscores President Trump’s firm stance on countering Iranian naval aggression, following U.S. Central Command’s elimination of 17 Iranian warships in the Middle East. Americans weary of globalist weakness under past administrations see this as vital defense of U.S. interests and allies in the Indo-Pacific.

Geopolitical Ramifications

The sinking raises questions about naval operations in international waters and international law adherence. If U.S. action confirmed, it signals escalation beyond Middle East theaters, shifting power balance in the Indian Ocean. Iran’s loss weakens its Southern Fleet projection amid routine multinational engagements. Sri Lanka’s neutral humanitarian role highlights regional stability efforts.
