BAE Systems will support and service aircraft countermeasures systems under a five-year, £16 million urgent-needs contract with the U.K. Ministry of Defence. The AAR-57 Common Missile Warning System (CMWS) integrates electronic warfare sensors to detect and defeat IR-guided missiles. CMWS is fielded on more than 120 systems on U.K. rotary- and fixed-wing aircraft, including the Chinook and Tornado. Under the contract, BAE Systems will manage all facets of the supply chain to guarantee availability of CMWS equipment spares to men and women in combat. BAE will provide spare systems and accept returned equipment for depot-level repair in the U.S. The contract also provides £1.5 million for spares equipment to support the program.
