U.S. Submarine Sinks Iranian Warship With Mk 48 Torpedo

A U.S. submarine sank the Iranian warship IRIS Dena in international waters in the Indian Ocean with a Mk 48 heavyweight torpedo, marking the first submarine-launched kill since World War II. The 3,744-pound torpedo carries a 650-pound warhead and can be wire-guided from the launch submarine or operate autonomously if the wire is lost, with ongoing hardware Mods and software updates to stay effective across modern undersea environments.
