ATK has received a $48-million production contract from the U.S. Navy for the manufacturing of the AAR-47 Missile Warning System.

The award encompasses production of new assemblies, including optical sensor converters and computer processors, as well as options for retrofitting weapon replaceable assembly upgrades and delivery of ATK's Countermeasures Signal Simulator (CSS) to test the systems operability.

ATK's AAR-47 Missile Warning System is a combat-proven electronic warfare system designed to protect helicopters and fixed-wing aircraft from surface-to-air threats. The AAR-47 is the only system in use today that integrates missile, laser and hostile fire threat warning into a single system. With ATK's unique Hostile Fire Indication (HFI) capability added to the AAR-47, military aircrews flying helicopters and fixed-wing aircraft can detect a wider range of threats to their aircraft, including smaller-caliber weapon fire and rocket propelled grenades.

“ATK's AAR-47 aircraft survivability system is installed on all U.S. Navy and Marine Corps helicopters and transport aircraft operating in combat and continues to save numerous aircrew lives and aircraft from attack,” said Bill Kasting, Vice President and General Manager of ATK Defense Electronic Systems.

“The addition of Hostile Fire Indication to the AAR-47 underscores our commitment to deliver improved capabilities that protect U.S. and allied military aircrews flying in harm's way,” he added.

“The AAR-47continues to provide the warfighter with a reliable, battle-proven, low-cost, missile and laser warning capability,” said Keith Taylor, Deputy Program Manager for the PMA-272 Aircraft Survivability Equipment Branch at the Naval Air Systems Command.

The AAR-47 missile warning system is installed on fixed and rotary-wing aircraft flown by the U.S. and its allies in more than 16 countries. The systems are installed on aircraft such as the A-10, C-5, C-17, C-130, MC-12W, P-3, CH-53, CH-46, HH/SH-60, AH-1W/Z, UH-1N/Y, and MV-22.
