Number of baseline (Mod 5) ADCAPs, and maintaining the total Produce about 1046 MODS ADCAPs, replacing an equivalent The ADCAPĮnhancement includes all digital guidance and control systems, digitalįuzing systems, and pro-pulsion improvements which add speed,ĭepth, and range capability. Torpedo with sophisticated sonar and a fuzed warhead. The MK 48 Mod 5 ADCAP torpedo is an improvement to the MKĤ8 submarine launched torpedo. High-powered active/passive sonar guides the torpedo during the final attack. This helps the torpedo avoid decoys and jamming devices that might be deployed by the target. Operator in the submarine, with access to the submarine's sensitive sonar systems, initially to guide the torpedo toward the target. As the torpedo leaves the submarine's launch tube a thin wire spins out, electronically linking the submarine and torpedo. The MK 48 has a sophisticated guidance system permitting a variety of attack options. The engine uses a liquid monopropellant fuel, and the torpedo hasĪ conventional, high-explosive warhead. The MK 48 is propelled by a piston engine with twin, contra-rotating propellers in a pump jet or shrouded configuration. The ADCAP version, in comparison with earlier MK 48 torpedoes, has improved target acquisition range, reduced vulnerability to enemy countermeasures, reduced shipboard constraints such as warmup and reactivation time, and enhanced effectiveness against surface ships. Both can conduct multiple reattacks if they miss the target.Ī highly capable weapon, the MK 48 can be used against surface ships or submarines, and has been test fired under the Arctic ice pack and in other arduous conditions. When launched they execute programmed target search, acquisition and attack procedures. MK-48 and MK-48 ADCAP torpedoes can operate with or without wire guidance and use activeĪnd/or passive homing. The SSN 714 Norfolk fired the first ADCAP torpedo on 23 July 1988, sinking the FORREST SHERMAN class destroyer DD 938 Jonas K. MK-48 ADCAP became operational in 1988 and was approved for full production in 1989. The MK-48 has been operational in the US Navy since 1972. The MK-48 replaced both the MK-37 and MK-14 torpedoes. The improved version, MK-48 ADCAP, is carried by attack submarines, the Ohio class ballistic missile submarines and will be carried by the Seawolf class attack submarines. The MK-48 is designed to combat fast, deep-diving nuclear submarines and high performance surface ships. The three major torpedoes in the Navy inventory are the Mark 48 heavyweight torpedo, the Mark 46 lightweight and the Mark 50 advanced lightweight. Submarines, surface ships, helicopters and fixed-wing aircraft. Torpedoes are self-propelled guided projectiles that operate underwater and are designed to detonate on contact or in proximity to a target.
