Raytheon Company has been awarded a $254 million contract modification for the completion of software development for the DDG 1000-class destroyer program. Under the contract, Raytheon Integrated Defense Systems (IDS) will perform development engineering activities for Total Ship Computing Environment Infrastructure integration, ship control systems, as well as associated Mission Systems Equipment software development and integration. The contract modification includes development, test and delivery of DDG 1000 Total Ship Computing Environment (TSCE) software for Self Defense Test Ship, post-delivery availability, post-shakedown availability, SPY-3 volume search software and firmware development, as well as software maintenance in support of the Zumwalt-class destroyer program. Raytheon's TSCE encompasses all shipboard computing applications, including the combat management system; command, control, communications, computers and intelligence elements; ship machinery control systems; damage control; embedded training; and support systems. The system leverages a modern open system architecture that provides a scalable platform for cost-efficient delivery of new mission capability.
