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 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;
