AAR-47 Missile Approach Warning System to be Changed, Retrofitted

AN/AAR-47 Components The AN/AAR-47 Missile Approach Warning System (MAWS) is a passive missile approach warning system consisting of four sensor assemblies housed in two or more sensor domes, a central processing unit, and a control indicator. Deployed on helicopters and transport aircraft, the AAR-47 deals with threat missile approach by detecting radiation associated with the rocket motor, letting the crew know that an attacking missile is coming and which direction it’s coming from, and automatically firing decoy flares. Detection algorithms are used to discriminate against non-approaching radiation sources. Alliant Integrated Defense Co. LLC in Clearwater, FL received an $8.7 million modification to a previously awarded firm-fixed-priced contract (N00019-98-C-0006). It covers incorporation of the AAR-47A(V)2 dynamic blanking sensor engineering change proposal into the existing production line, and also the retrofit of existing sensors in the US Navy and Air Force. Modification provides for sensor production cut-in of 751 Navy sensor units; sensor retrofit of 1,173 Navy sensor units; sensor production cut-in of 328 USAF sensor units; and sensor retrofit of 275 USAF sensor units. Work will be performed in Clearwater, Fla., and is expected to be completed in October 2008. The Naval Air Systems Command in Patuxent River, MD issued the […]
