The MK-48 is designed to combat fast, deep-diving nuclear submarines and high performance surface ships. The MK-48 has been in service in the U.S. Navy since 1972. MK-48 ADCAP entered service in 1988.

MK-48 and MK-48 ADCAP torpedoes can operate with or without wire guidance and use active and/or passive homing. When launched they execute programmed target search, acquisition and attack procedures. Both can conduct multiple re-attacks if they miss the target.
