The Navy has awarded Raytheon [RTN] $240 million for production and delivery of critical components of the Aegis weapons system for the Arleigh Burke-class of destroyers, the company said last week.

Under the contract, Raytheon will provide production, engineering and support services for four ship sets of the SPY-1D(V) transmitter group and Mk 99 Mod 8 Fire Control System, company executives said. The radar and fire control system equipment is essential to the Aegis system’s ability to track and defend against multiple threats.

“Raytheon’s naval radar components are providing extensive capabilities and proven performance for Aegis-equipped ships worldwide,” said Raytheon’s John Kelly, director of Sensor Systems. “This current contract continues Raytheon’s legacy as a key contributor to the Aegis program and as an industry leader in the design and development of naval radars.”

Raytheon’s SPY-1 radar transmitters and Mk 99 Fire Control System have been in continual production for 30 years as part of the Navy’s Aegis shipbuilding program. The SPY-1 and the Mk 99 are currently installed in the U.S. Navy’s fleet of Ticonderoga-class cruisers and Arleigh Burke-class destroyers, as well as in Japanese Kongo-class destroyers and Spanish F100-class frigates.

Work on the Aegis program is performed at Raytheon’s Surveillance and Sensors Center, Sudbury, Mass.; at the Seapower Capability Center, Portsmouth, R.I.; and at the Integrated Air Defense Center, Andover, Mass. The $240 million contract contains options for additional work.

Last week, four companies submitted entries for the Missile Defense Agency‘s next-generation ballistic missile interceptor, currently planned for fielding in 2020. Boeing [BA], Lockheed Martin [LMT], Northrop Grumman [NOC] and Raytheon are bidding on the contract.
