Raytheon Co., Tucson, Ariz., is being awarded a not-to-exceed $161,030,943 modification to previously awarded contract (N00024-10-C-5427) for MK15 Mod 31 SeaRAM systems in support of LCS 6 and 8 and Japan’s DDH 2405 helicopter destroyer, as well as Phalanx Close-In Weapon System (CIWS) Block 1B class “A” overhauls, and land-based Phalanx Weapon System class “A” overhauls.

CIWS is a fast-reaction terminal defense against low- and high-flying, high-speed maneuvering anti-ship missile threats that have penetrated all other defenses. Operating either autonomously or integrated with a combat system, it is an automatic terminal defense weapon system designed to detect, track, engage, and destroy anti-ship missile threats penetrating outer defense envelopes. Phalanx CIWS is currently installed on approximately 152 Navy and 14 Coast Guard ships and is in use in 23 foreign navies.
