Udav-1 anti-submarine system

The UDAV-1 system is a Russian ship-borne Anti-submarine weapon system. The weapon fires a number of different types of rockets, which in addition to attacking submarines provide a multi-layer defence against torpedoes and frogmen. The system operates in conjunction with the ship's sonar.

The system consists of:

• A KT-153 remotely controlled multi-barrel automated rocket launcher with indirect elevation/traverse stabilisation;
• 111SG depth-charge rockets with HE warhead and impact-time fuze to engage underwater targets;
• 111SZ mine-laying rockets with hydro-acoustic proximity fuze for remote mining of a water area to make a barrier for incoming torpedoes;
• 111SO decoy rockets to divert homing torpedoes from the surface ship by creating false acoustic target;
• fire control devices;
• an ammunition loading device;
• ground support equipment.
