The APR-3E airborne light ASW acoustic homing torpedo is designed by Russian Tactical Missiles Corporation JSC to engage current and future submarines in at depth from the surface down to 800 metres at speed of up to 43+ knots, and it is a replacement for earlier APR-2 light antisubmarine acoustic homing torpedo.
APR-3E airborne light antisubmarine acoustic homing torpedo is designed to be carried by a various fixed wing and rotary wing platform including Tu-142, Il-38, Ka-28 and other aircraft. The torpedo requires at least 100 metres depth of water for the initial air-drop and can be deployed in conditions up to sea state 6.
Once entering water, the control surfaces of the torpedo enable the torpedo to travel in a spiral path with the help of gravity without starting the engine. During this stage, the acoustic seeker of the torpedo searches for targets. Once the target is identified, the engine starts and solid propellant rocket engine ensures the targets has virtually very little or no time to react, thus increasing the kill probability.
