RBU-1000

The RBU-1000 Smerch-3 is a 300 mm caliber Russian anti-submarine and anti-torpedo rocket launcher. It entered service around 1962-1963. It is similar in operation to the Hedgehog system used during the Second World War. The RBU-1000 is remotely aimed by the Burya fire control system (which is also used by the RBU-6000 system). It is crewed by three men, two in the magazine room, one in the control center.

The launcher consists of six barrels which are automatically loaded one at a time from a below deck magazine that holds either 60 or 48 rounds per launcher. The system's reaction time is around two minutes between initial target detection and the first salvo reaching the target, though this can be reduced to under one minute if some target data is pre-entered (for example depth and speed). A salvo consists of 1, 2, 4 or 6 RGB-10 rockets, with a gap of around a second between successive rockets. Reloading takes less than three minutes.

The rockets travel in a ballistic arc and strike the water, sinking rapidly and are either detonated when reaching a depth set at launch or on impact with a target.

RBU-6000

The RBU-6000 Smerch-2 (Реактивно-Бомбовая Установка, Reaktivno-Bombovaja Ustanovka; reaction engine-bomb installation & Смерч; waterspout) is a 213 mm caliber Soviet anti-submarine rocket launcher. It is similar in principle to the Royal Navy Hedgehog system used during the Second World War. The system entered service in 1960-61 and is fitted to a wide range of Russian surface vessels. It consists of a horseshoe shaped arrangement of twelve launch barrels, that are remotely directed by the Burya fire control system (that can also control the shorter ranged RBU-1000). It fires RGB-60 unguided depth charges. The rockets are normally fired in salvos of 1, 2, 4, 8 or 12 rounds. Reloading is automatic, with individual rounds being fed into the launcher by the 60UP loading system from a below deck magazine. Typical magazine capacity is either 72 or 96 rounds per launcher. It can also be used as a shore bombardment system.

The RPK-8 system is an upgrade of the RBU-6000 system, firing the 90R rocket, which is actively guided in the water. This allows it to home in on targets at depths of up to 1,000 meters. The warhead is a 19.5 kg shaped charge, which enables it to punch through the hulls of submarines. It can also be used against divers and torpedoes. System response time is reported to be 15 seconds and a single-salvo has a kill probability of 0.8.

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:
