MINNEAPOLIS, 1 June 2011. The Department of the Navy has approved for fleet introduction ATK’s Hostile Fire Indication (HFI) capability upgrade for the AAR-47 Missile Warning System. The HFI capability, which complements the AAR-47's combat-proven ability to detect incoming missile threats, detects smaller-caliber weapon fire and rocket-propelled grenades.

Using the AAR-47 upgraded with ATK's HFI capability, military aircrews flying rotary- and fixed-wing aircraft can detect a wide range of threats to their aircraft and respond with countermeasures. The HFI will be provided as a software upgrade and requires no hardware modifications to the aircraft or existing AAR-47 components. The upgrade is scheduled for delivery later this year.

"The Navy's decision to deploy ATK's HFI upgrade to the Fleet brings aircrews the very best protection from hostile ground fire," says Bill Kasting, vice president and general manager of ATK Defense Electronics Systems. "We are proud to help protect aircrew lives during combat by delivering this innovative and affordable capability."

ATK's AAR-47 Missile Warning System is an electronic warfare system designed to protect helicopters and fixed-wing aircraft from surface-to-air threats. The AAR-47 integrates laser and missile warning into a single system. The system is installed on more than 2,600 fixed and rotary-wing aircraft--such as the C-5, C-17, C-130, P-3, CH-53/MH-53, CH-46, HH/SH-60, AH-1W/Z, UH-1N/Y, and MV-22--flown by the U.S. and its allies in 16 countries.
