BAE Systems will provide laser warning sensor sets to protect U.S. military aircraft under a $17.7 million contract by Alliant Techsystems. The contract provides components for the AAR-47 Missile Approach Warning System, part of the ongoing U.S. Navy road map of airborne protection and system improvements for U.S. Navy, Air Force, Army, and foreign allied fleets. The laser detection sensors provide critical warning systems for hostile threats. A prime contractor and development partner, Alliant Techsystems provides integration and delivery of the AAR-47 system to the military. The sole-source award to the Austin, TX, facility is for the Naval Air Systems Command's production and spares requirements. The circuit card assemblies are built in Wayne, NJ, and Austin, TX. Deliveries will begin in July 2011 and run through November 2012.
