The torpedo attack off the coast of Sri Lanka was the first such sinking by the US Navy since World War II, Defense Secretary Hegseth said.

The U.S. Navy will occasionally sink its own old, unwanted ships, but it's an expensive business, so why would it want to do a thing like that?

The U.S. Navy struck and sunk an Iranian warship in international waters on Tuesday, Defense Secretary Pete Hegseth said.

Donald Trump has been condemned online for retelling a story he apparently had with a US military chief about sinking Iranian ships

Sri Lankan foreign minister Vijitha Herath identified an Iranian naval ship that issued a distress signal and sank off the coast of the country as the IRIS Dena in remarks to Parliament. A ship by that name arrived in the Indian port of Visakhapatnam on Feb.
