The APR-3E airborne light ASW acoustic homing torpedo is designed by Russian Tactical Missiles Corporation JSC to engage current and future submarines 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.
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 the target is identified, the engine starts and solid propellant rocket engine ensures the target has virtually very little or no time to react, thus increasing the kill probability.
Trials of the APR-3M missile have been completed, the process of its serial production has been organized and its deliveries to the Ministry of Defence of Russia are underway as of May 2019.
