Lockheed Martin has been awarded a $37 million contract by the US Navy to provide upgrade kits and services for the MK 48 heavyweight torpedo. The Mod 7 Common Broadband Advanced Sonar System (CBASS) upgrade kit will equip the torpedo with increased bandwidth and streamlined targeting and tracking capabilities. The replacement kits will upgrade the heavyweight torpedoes used by the entire United States submarine fleet for anti-submarine or anti-surface warfare, as well as those employed by the allied navies of Australia, Canada, and The Netherlands. The work will be carried out at Lockheed Martin’s Marion, Mass., facility with additional support from other company locations.
