Udav-1 anti-submarine system
From Wikipedia, the free encyclopedia
The UDAV-1 system is a Russian ship borne submarine defense system designed to use different types of rockets for highly efficient multi-layer defence of surface ships against torpedoes. The system is also capable of engaging submarines and frogmen.
The system comprises:
- the KT-153 remotely controlled multi-barrel automated launcher with indirect elevation/traverse stabilisation;
- the 111SG depth-charge rockets with HE warhead and impact-time fuze to engage underwater targets;
- the 111SZ mine-laying rockets with hydroacoustic proximity fuze for remote mining of a water area to make a barrier for incoming torpedoes;
- the 111SO decoy rockets to divert homing torpedoes from the surface ship by creating false acoustic target;
- the fire control devices;
- the ammunition lading device;
- ground support equipment.
The UDAV-1 MLRS operates in conjunction with the ship's sonar.
