APR-3E

The APR-3E is a torpedo powered by a turbo water-jet solid-propellant rocket motor and is designed to destroy surfaced and submerged submarines at a depth of up to 800 meters and moving at speeds of up to 45 knots. It was developed to be released by airborne platforms such as helicopters and fixed-wing aircraft (Tu-142, Il-38, Ka-28, Mi-17). The APR-3E utilizes a passive acoustic homing head with the engine shut during gravity submersion along a spiral trajectory. The homing head can detect targets at ranges of up to 2,000 meters. Once the APR-3E has detected a potential target the engine ignites and the APR-3E is ensured to hit the designated target in 1 or 2 minutes which shortens the odds of the target applying countermeasures or getting away. The underwater missile has a top speed of 120 kph or 65 knots with an engine endurance of 113 seconds. The Russian missile torpedo can detect and engage targets below a maximum speed which is 45 knots for the APR-3E.
