Here Comes the Navy’s First New Torpedo in Decades

The U.S. Navy plans to field its first new torpedo in decades, and one candidate is Northrop Grumman's Very Lightweight Torpedo (VLWT).

Originally designed to protect aircraft carriers from incoming torpedoes, VLWT could be used by aircraft, surface ships, and even submarines. The weapon can be used both as an offensive weapon against enemy submarines, or a defensive one against inbound torpedoes.
