Raytheon to build radar fire-control systems for Aegis shipboard electronics aboard Burke-class destroyers
WASHINGTON – Shipboard electronics experts at Raytheon Technologies Corp. are building two MK 99 fire-control systems for the Aegis weapon system aboard U.S. Navy Arleigh Burke-class destroyers under terms of a $38.8 million contract announced on Thursday.
Officials of the Naval Sea Systems Command in Washington are asking the Raytheon Intelligence & Space segment in Marlborough, Mass., to build two MK 99 Aegis fire-control systems and engineering in support of the Aegis combat systems aboard Burke-class destroyers.
The MK 99 fire-control system functions as the interface between the Aegis AN/SPY-1 radar and the ship-launched SM-2 family of anti-air missiles. The MK 99 fire-control system communicates with the missile-control station, notifying it of the air threat, and then illuminates the missile's target.
The MK 99 also controls the loading and arming of shipboard missiles aboard Burke-class destroyers and Ticonderoga-class cruisers. The MK 99 launches and provides terminal guidance for the ship's missiles, and controls the continuous-wave illuminating radar to provide a high probability of target kill.
The Aegis weapon system comprises the AN/SPY-1 radar, the MK 99 fire control system, weapon control system (WCS), the command and decision suite, and SM-2 Standard missile family, which includes the basic RIM-66, the RIM-67 extended range, and the newer RIM-161 to counter ballistic missiles. The extended-range RIM-174 was deployed in 2013.
The MK 99's radar transmitter is being upgraded to improve performance and reduce acquisition and maintenance costs. The MK 99 illuminator transmitter upgrade is replacing obsolescent traveling wave tube (TWT) technology with solid-state transmitters to improve the MK 99's mean time between failures.
The system's solid-state transmitter and open-systems architecture also will enable upgrades for new technologies and capabilities over the lifetime of system.
On this contract Raytheon will do the work in Andover, Marlborough, and Burlington, Mass; Chesapeake, Va.; Portsmouth, R.I.; and San Diego, and should be finished by August 2024.
