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.
