ATK has secured a contract to supply survivability equipment for installation on-board the Republic of Korea Army’s (ROK) AH-1S Cobra attack helicopters.

Under the $7m firm fixed-price contract, the company will acquire, install and integrate its AAR-47 missile warning system with hostile fire indication (HFI and Laser Warning) onto AH-1S helicopters.

The competitively awarded contract also covers installation of the AN/ALE-47 countermeasure dispensing system (CMDS).

ATK Defense Group Defense Electronic Systems division vice-president and general manager Bill Kasting said the company’s warning systems provide the aircraft with the ability to detect and react against hostile threats in combat.

"The AAR-47 missile warning system is designed to safeguard helicopters and fixed-wing aircraft from surface-to-air threats."

"ATK’s goal is to provide our customers with the accuracy and reliability they expect, while enhancing the overall effectiveness of their flight-platform missions," Kasting said.

ATK Defense Group president Mike Kahn said: "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."

Claimed to be the only system that integrates missile, laser and hostile fire threat warning into a single platform, the AAR-47 missile warning system is designed to safeguard helicopters and fixed-wing aircraft from surface-to-air threats.

The combat-proven electronic warfare (EW) system, together with its HFI capability enables military aircrews flying helicopters and fixed-wing aircraft to detect a wide range of threats, including smaller-calibre weapon fire and rocket propelled grenades, to their aircraft and quickly respond with appropriate countermeasures.

The system is currently installed on more than 3,200 fixed and rotary-wing aircraft belonging to the US and its allies worldwide 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.

A complement to AAR-47 system, the AN/ALE-47 CMDS offers enhanced survivability to combat aircrews against surface-to-air and air-to-air missile threats in all environments by dispensing chaff or flares.
