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 defense 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 stabilization;
- 111SG depth-charge rockets with HE warhead and impact-time fuse to engage underwater targets;
- 111SZ mine-laying rockets with hydro-acoustic proximity fuse 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.
