The Mark 48 and its improved Advanced Capability (ADCAP) variant are American heavyweight submarine-launched torpedoes. They were designed to sink deep-diving nuclear-powered submarines and high-performance surface ships.

The weapon is carried by all U.S. Navy submarines, including Ohio-class ballistic missile submarines and Seawolf-, Los Angeles-, and Virginia-class attack submarines. It is also used on Canadian, Australian, and Dutch submarines.

The swashplate piston engine is fueled by Otto fuel II, a monopropellant that combusts to drive the engine. The thrust is generated by a propulsor assembly.

The Mark 54 Lightweight Torpedo (formerly known as Lightweight Hybrid Torpedo, or LHT) is a standard 12.75-inch (324 mm) anti-submarine warfare (ASW) torpedo used by the United States Navy.
