The Mk-48 torpedo is designed to be launched from submarine torpedo tubes. It was designed by the British Royal Navy. It is also carried by all U.S. Navy submarines, including Ohio-class ballistic missile submarines and Seawolf, Los Angeles and Virginia attack submarines. It is also used on Canadian, Australian and Dutch submarines. The Royal Navy uses a similar class of torpedo, the Spearfish. The Royal Navy of the United Kingdom is the oldest of the British armed services (and is therefore the Senior Service). ...

Mk-48 and Mk-48 ADCAP torpedoes can be guided from a submarine by wires attached to the torpedo. They can also use their own active or passive sensors to execute programmed target searches, acquisition and attack procedures. The torpedoes are designed to detonate under the keel of a surface ship, breaking the ship's back and destroying its structural integrity. Both can circle back and try again if they miss. A wire is a single, usually cylindrical, elongated strand of drawn metal. ...

The official performance data may be a gross understatement, according to non-military sources that put the depth at deeper than 600 meters, the top speed between 60 to 75 knots (110 to 140 km/h), the range at top speed at more than 20 nautical miles (37 km), and the range at lower speeds at more than 30 nautical miles (56 km).

Sensors and improvements The torpedo's seeker has an active electronically-steered "pinger" which helps avoid having to maneuver as it closes with the target. Unconfirmed reports indicate that the torpedoes' sensors can monitor surrounding electrical and magnetic fields. This may refer to the electromagnetic coils on the warhead (at least from 1977 to 1981), used to sense the metallic mass of the ship's hull and detonate at the proper stand-off distance. Electromagnetism is the physics of the electromagnetic field: a field which exerts a force on particles that possess the property of electric charge, and is in turn affected by the presence and motion of those particles. ...

According to various sources, continued improvement has been in progress. In the 1990s, a Mod6 variant of the ADCAP has provided much improved noise isolation of the engine, which makes this torpedo more difficult to be detected by any potential target(s). In the early 2000s, upgrade design works (codename CBASS Common Broadband Advanced Sonar System) was started to improve shallow water target detection capability and counter-countermeasure capability.
