Sri Lanka Recovers 87 Bodies from Iranian Warship Sunk by U.S. Submarine in Historic Torpedo Strike

COLOMBO, Sri Lanka (AP) — Rescue teams in Sri Lanka recovered 87 bodies Thursday from the wreckage of the Iranian frigate IRIS Dena, which a U.S. Navy fast-attack submarine sank in the Indian Ocean on Tuesday with a single Mk-48 torpedo. The attack marks the first time an American submarine has destroyed an enemy warship since World War II, Defense Secretary Pete Hegseth confirmed during a Pentagon briefing Wednesday.

Sri Lankan authorities reported rescuing 32 survivors from the ship's 180-member crew, with approximately 60 sailors still unaccounted for as search operations continued amid rough seas off the southern coast. "Yesterday, in the Indian Ocean, an American submarine sunk an Iranian warship that thought it was safe in international waters," Hegseth told reporters. "Instead, it was sunk by a torpedo. Quiet death."

The incident has thrust the normally neutral island nation into the center of escalating U.S.-Iran tensions, drawing international condemnation from Tehran and cautious statements from regional powers like India and China. As debris fields stretched for miles and oil slicks threatened local fisheries, Sri Lankan President Anura Kumara Dissanayake called an emergency cabinet meeting, urging de-escalation while pledging humanitarian aid to the Iranian survivors.

A Historic Kill Resurfaces Submarine Warfare Tactics

The strike occurred roughly 40 kilometers south of Sri Lanka's Dondra Head, the southernmost tip of the island, placing it squarely in international waters. This event represents not just a U.S. milestone but the first submarine torpedo kill by any navy since the Royal Navy's HMS Conqueror torpedoed the Argentine cruiser ARA General Belgrano during the 1982 Falklands War, killing 323 sailors and shifting the conflict's momentum.

Pentagon-released video footage, declassified Wednesday, captured the dramatic moment: a sleek Mk-48 Advanced Capability torpedo—capable of speeds over 50 knots and homing in on underwater targets with wire-guided precision—slammed into the Dena's stern. The explosion ripped the 1,500-ton Moudge-class frigate in half, sending it to the seabed in under two minutes. "An incredible demonstration of America's global reach," said Chairman of the Joint Chiefs of Staff Gen. Dan Caine. "To hunt, find, and kill an out-of-area deployer is something that only the United States can do at this type of scale."

The submarine's identity remains classified under standard operational security protocols, but defense analysts speculate it was one of the Virginia-class boats forward-deployed to the U.S. 7th Fleet in the Indo-Pacific. These nuclear-powered hunters, armed with up to 38 weapons including Tomahawks and Harpoons, embody post-Cold War undersea dominance. "Submarines have evolved from stealthy scouts to decisive strike platforms," noted retired Navy Capt. John Miller, a submarine warfare expert at the Naval War College. "The Mk-48's pump-jet propulsor and acoustic countermeasures make it virtually undetectable until it's too late."

Hegseth highlighted the irony of the target: the Dena bore the nickname "Soleimani," honoring Qasem Soleimani, the IRGC Quds Force commander killed in a 2020 U.S. drone strike near Baghdad ordered by then-President Donald Trump. "Last night, we sunk their prized ship, the Soleimani," Hegseth quipped. "Looks like POTUS got him twice."

Broader Conflict: Operation Epic Fury Unfolds

This sinking is just one chapter in Operation Epic Fury, the sweeping U.S. military campaign against Iran that Trump greenlit on February 28, 2026, amid heightened proxy attacks on American interests in the Middle East. In its opening 72 hours, U.S. forces—drawing from carrier strike groups, B-2 bombers, and special operations units—hammered over 1,700 targets inside Iran. These included hardened command bunkers, S-400 air defenses, underground missile silos, and key naval bases along the Persian Gulf.

Gen. Caine reported Thursday that coalition forces had neutralized more than 20 Iranian surface vessels, effectively dismantling Tehran's major naval projection capabilities. "We've shattered their ability to threaten shipping lanes or project power beyond the Strait of Hormuz," he said. Satellite imagery from Maxar Technologies corroborates the claims, showing smoldering wrecks at Bandar Abbas and charred craters at Fordow.

The IRIS Dena itself was no ordinary patrol boat. Commissioned in 2019 as Iran's most advanced surface combatant, the 95-meter frigate bristled with C-802 anti-ship missiles, Nasr torpedoes, and a 76mm Oto Melara deck gun. It had just wrapped participation in the Indian Navy's multinational MILAN exercise in Visakhapatnam, a biennial gathering of 50 nations showcasing Indo-Pacific interoperability. En route home via the Arabian Sea, the Dena was shadowed for days by U.S. intelligence assets before the fatal intercept.

Humanitarian Crisis on Sri Lanka's Shores

Sri Lanka's involvement began at dawn Tuesday when the frigate's SOS lit up regional maritime channels. Colombo dispatched four offshore patrol vessels, two helicopters, and the Sri Lanka Navy's SLNS Sayurala, racing to coordinates 6°10'N, 81°45'E. By Wednesday, the toll mounted: 87 bodies lined the Galle District Hospital morgue, many burned beyond recognition from secondary fires ignited by the torpedo hit.

Foreign Minister Vijitha Herath addressed parliament Thursday, detailing the rescue of 32 critically wounded sailors now stabilizing in intensive care. "Our doctors are working around the clock," he said. "Many suffered blast trauma, hypothermia, and oil burns." The unaccounted 60 likely succumbed to the sea's depths, as currents dispersed wreckage across 20 square nautical miles. Fishing communities in Matara reported spotting life jackets and debris, prompting a no-fish zone.

Iran's ambassador to Colombo, Mohammad Reza Sabouri, decried the attack as "state piracy" and demanded a UN investigation. Tehran has vowed retaliation, with Supreme Leader Ali Khamenei labeling it "martyrdom by American aggression." Meanwhile, the 32 survivors—many in their 20s—have become symbols of the conflict's human cost, their families pleading via state media for repatriation.

Geopolitical Ripples Across the Indian Ocean

The incident exposes fault lines in the Indo-Pacific. India, host of the Dena's last exercise, issued a measured statement urging restraint while quietly boosting patrols in the Andaman Sea. China, Iran's top oil buyer, condemned the U.S. action at the UN Security Council, where Russia proposed a resolution branding it an "act of war." President Trump dismissed the rhetoric during a Mar-a-Lago presser: "Iran's been lobbing drones at our bases for months. This is proportionality."

Experts warn of escalation risks. "The Indian Ocean is now a live theater," said Brookings Institution fellow Sumitra Singh. "Closing the Bab el-Mandeb or Hormuz could spike global oil to $150 a barrel." Environmentalists fret over the 500 tons of fuel aboard the Dena, with slicks already fouling coral reefs vital to Sri Lanka's $250 million tourism industry.

For the U.S., the kill burnishes its undersea edge amid peer competition with China and Russia. Yet it revives Falklands-era debates on rules of engagement: Was the Dena a legitimate threat in international waters? Pentagon lawyers cite Iran's history of seizing tankers and arming Houthis as justification.

As Thursday dawned, Sri Lankan divers prepared another sweep, the ocean yielding its grim secrets. Operation Epic Fury rages on, but for the 180 souls of the IRIS Dena, the war ended in silent torpedo fire—a stark reminder that modern conflicts claim lives far from front lines.
