BAE Systems has secured foreign military sales contracts from the US Army worth $137 million to supply AN/AAR-57 Common Missile Warning Systems (CMWS) to allied countries.
The system detects infrared- and radio frequency–guided missiles, which can be launched with little warning and engage aircraft within seconds. It supports aircraft survivability by providing automatic alerts and countermeasure cues to aircrews.
Under the contracts, CMWS will be delivered to fleets operated by over 20 partner nations.
The technology is currently integrated across more than 40 different fixed- and rotary-wing aircraft types worldwide, including platforms such as Boeing’s AH-64 Apache.
In total, over 3,000 systems have been installed, accumulating more than four million flight hours in operational environments.
CMWS is designed and manufactured at BAE Systems facilities across the US, including sites in Alabama, Texas, and New Hampshire.
The recent contract builds on a 2024 award, under which BAE Systems received $114 million in US Army foreign military sales funding for CMWS.
Common Missile Warning Systems
CMWS is the US Army’s standard missile warning system and is compatible with existing chaff, flare, and radio frequency decoy dispensers, as well as directed infrared countermeasure systems.
It can also serve as a central processing system within an integrated aircraft survivability suite, integrating sensor inputs and coordinating countermeasure responses across multiple defensive subsystems.
In addition to missile warning, CMWS provides hostile fire indication, including detection of small-arms fire and rocket-propelled grenades, and supports data recording for post-mission analysis.
The system’s software architecture enables threat detection algorithms to be updated as new missile and hostile-fire profiles emerge, supporting continued use against evolving threats.
