Orbital ATK validates Shotfinder Acoustic Warning System on fixed-wing aircraft


Orbital ATK, a global leader in aerospace and defense technologies, announced it has completed testing and characterization of its ShotFinder Acoustic Hostile-Fire Indication System on a fixed-wing aircraft.

The ShotFinder system, installed on a Cessna Grand Caravan aircraft configured for intelligence, surveillance and reconnaissance, collected ambient acoustic data while the aircraft was being subjected to a variety of operating scenarios. Data analysis and simulated live-fire data injection indicates the system will accurately produce hostile-fire indications from the expected threats.

“Orbital ATK’s ShotFinder has previously been shown to be effective against a variety of incoming enemy-arms fire when utilized on rotary-wing platforms,” said Cary Ralston, Vice President and General Manager of the Defense Electronic Systems Division of Orbital ATK’s Defense Systems Group. “The additional data collection on a fixed-wing platform broadens the potential user base to allow Caravan and other fixed-wing pilots the improved means to safely complete their mission.”

ShotFinder identifies and directionally locates small-arms fire, anti-aircraft artillery and rocket-propelled grenade threats. Orbital ATK, together with Scientific Applications and Research Associates (SARA), developed the acoustic hostile-fire warning system by using the supersonic shock wave from a passing bullet and the muzzle blast from the weapon to determine a bullet’s origin and point of closest approach. ShotFinder has a high probability of hostile-fire detection and a low false-alarm rate, and relays a real-time directional warning to the pilot.
