Westinghouse says that its AAR-54 passive missile-approach warning system successfully detected all missiles fired at it during a two-day live-fire demonstration conducted by the US Navy at its China Lake, California, test range. The missile-warning device, also known as the PMAWS-2000, was mounted on an USN QF-4 drone aircraft and incorporated within the aircraft's mission computer and its ALE-47 countermeasures dispenser system. A total of 14 missiles were fired at the QF-4, which cued the ALE-47 to deploy decoy flares.
