AI Summary
The U.S. Navy's Mk 48 torpedo, a heavyweight undersea weapon, recently sank the Iranian warship IRIS Dena in the Indian Ocean, marking the first U.S. submarine torpedo sinking of an enemy ship since World War II. The Mk 48, in service since 1972 and continuously upgraded, is designed to destroy surface ships and submarines. The submarine-launched torpedo uses both external information and its own sensors for targeting, and can be guided by wire or autonomously. Weighing over 3,700 pounds, it carries a 650-pound high-explosive warhead and costs approximately $4.2 million per unit. Lockheed Martin is a primary contractor, and the torpedo has evolved through various "Mods" with upgraded systems; the Mod 7 is currently in use, with Mods 8 and 9 in development.
