ATK To Supply Aircraft Survivability Equipment to South Korean Army

ATK has received a contract from the Republic of Korea Army for the purchase, installation and integration of its AAR-47 Missile Warning System with Hostile Fire Indication (HFI and Laser Warning) onto AH-1S helicopters.

The upgrade will also include the installation of the AN/ALE-47 countermeasure dispensing system. 

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 program was awarded as a result of a competition with a firm fixed-price contract for $7 million to upgrade the helicopters. 

"We are pleased that we were selected for this program and we look forward to a long lasting relationship with the Defense Acquisition Program Administration," said Mike Kahn, president of ATK Defense Group. "This contract supports our focus on providing high-value to our customers, allowing ATK to have continued expansion of its aircraft survivability equipment across key international platforms." 


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 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, and quickly respond with countermeasures. ATK is the only company to deliver this key capability as part of a proven missile warning system. 

The AAR-47 missile warning system is installed on more than 3,200 fixed and rotary-wing aircraft and is flown by the U.S. and its allies in more than 16 countries. The systems are installed on aircraft such as the C-5, C-17, C-130, P-3, CH-53/MH-53, CH-46, HH/SH-60, UH-60P, AH-1W/Z, UH-1N/Y and MV-22. 

The Symetrics AN/ALE-47 CMDS is an Electronic Warfare self-protection suite that provides combat aircrews with enhanced survivability against surface-to-air and air-to-air missile threats in all environments, by dispensing chaff or flares, and is a complement to ATK's AAR-47.
