U.S. Submarine Sinks Iranian Warship in Indian Ocean

A U.S. submarine sank an Iranian warship operating in the Indian Ocean, threatening to sneak in on American carrier strike groups in the Persian Gulf and Arabian Sea. Secretary of War, Pete Hegseth, “said a torpedo from a U.S. submarine sank an Iranian warship in the Indian Ocean Tuesday night,” the Associated Press reported.

“In the Indian Ocean, an American submarine sunk an Iranian warship that thought it was safe in international waters,” Secretary Hegseth said. “Instead, it was sunk by a torpedo—Quiet Death.”

According to the BBC, the Sri Lankan officials “identified the warship as the frigate IRIS Dena.” The weekly India Today identified the Iranian warship as “Moudge-class frigate” sailing “about 40 nautical miles off Sri Lanka’s coast” when it was torpedoed.

The Operation Epic Fury continues to make military history. This is the first time since the Second World War that a torpedo has sunk a warship, Secretary Hegseth confirmed.

The CNBC News reports:

A U.S. submarine fired a torpedo that sunk an Iranian warship in the Indian Ocean, Defense Secretary Pete Hegseth said.“Quiet death,” Hegseth boasted of the attack, which he said was the “first sinking of an enemy ship by a torpedo since World War Two.”Gen. Dan Caine, chairman of the Joint Chiefs of Staff, said the sub used a “single Mark 48 torpedo to achieve immediate effect, sending the warship to the bottom of the sea.”The U.S. has “effectively neutralized, at this point in time, Iran’s major naval presence in theater out there.”

Earlier today, the Israeli media reported that one of their F-35i had shot down a Russian-made Iranian fighter jet in a dog fight over the skies of Tehran. “The engagement marked the first time in history that a crewed fighter jet was shot down by an F-35 in operational combat,” the newspaper Israel Hayom reported.
