Mark 35 torpedo

The Mark 35 torpedo was the first of the United States Navy deep-diving anti-submarine torpedoes designed for surface launch. This electrically propelled 21-inch (53-cm) torpedo was 162 inches (4.11 m) long, weighed 1,770 pounds (800 kg), and carried a 270-pound (120 kg) HBX warhead. This torpedo used one of the earliest active guidance systems and was introduced in 1949, and was classified as obsolete in the 1960s.
The Mark 35 torpedo was originally specified as the intended payload for the Grebe missile, before being replaced by the Mark 41 due to weight concerns.
