The APR-3E ASW missile is designed to destroy submarines moving at a speed of 80 km/h at a depth of up to 600 m. Underwater space is scanned by the hydroacoustic homing system during the missile’s gravity- induced descent on a spiral trajectory with the missile engine shut. The APR-3E missile is powered by a turbo waterjet solid-propellant motor.

The missile can arm the IL-38 aircraft and the Mi-14 and Ka-28 helicopters. Airborne ASW missiles, in contrast to conventional torpedoes, have maximum operating speed in the target acquisition and detection modes, accelerated approach to the target with destruction before the target can apply countermeasures.
