WASHINGTON, 6 March 2011. The U.S. Navy is asking Lockheed Martin Sippican Inc. in Marion, Mass., to build and deliver Common Broadband Advanced Sonar System (CBASS) functional item replacement (FIR) kits for the MK 48 Advanced Capability (ADCAP) MOD 7 heavyweight torpedo under terms of a $50.7 million contract, announced Friday.The CBASS replacement kit consists of a guidance and control box, broadband analog sonar receiver, preamplifier, cable assemblies, and guidance and control materials. The kit will provide the MK 48 ADCAP torpedo with a wideband sonar and advanced broadband signal processing algorithms to enable the torpedo to attack targets effectively in noisy shallow waters and harbors, as well as those using advanced torpedo countermeasures.
The MK 48 ADCAP torpedo is the primary anti-submarine and anti-ship weapon for Los Angeles- and Virginia-class fast attack submarines, and built by the Raytheon Co. Integrated Defense Systems segment in Keyport, Wash.
The MK 48 ADCAP heavyweight torpedo is the submarine's key weapon for attacking surface ships and other submarines. The MK 48 is 19 feet long, weighs more than 3,500 pounds, and has advanced homing, wire guidance capabilities, and packs a powerful punch with its 660-pound high-explosive warhead. It is designed to kill fast, deep-diving nuclear submarines and high-performance surface ships.
