Under the contract, the company will provide computer graphical user interfaces and a technical data manager capability to control Zumwalt's ship propulsion, integrated power, auxiliary and damage control systems. The deal will also include support to land-based and shipboard testing of these subsystems.

The work on this contract modification will be undertaken at Raytheon IDS Headquarters, Tewksbury, Massachusetts, and at the Seapower Capability Center, Portsmouth, Rhode Island.

Robert Martin, vice president and deputy of Seapower Capability Systems of Raytheon Integrated Defense Systems, said: "This is the most readily expandable, sophisticated software suite ever designed for a naval surface combatant, allowing the warfighter to address threats faster and more effectively than ever before. The high level of automation and intuitive human-computer interface of the ship's systems will dramatically reduce manning, resulting in significant cost savings for the navy."

Earlier this month, Raytheon won a five-year $197m contract from the US Navy to provide life-cycle engineering and support for its next generation LPD 17 amphibious warfare ships. In April, it won a $16.5m contract extension from the US Navy to migrate its current Tactical Control System to a Linux-based operating system and provide upgrades for the system software.
