The RBU-1200 (Russian: Реактивно-Бомбовая Установка, Reaktivno-Bombovaja Ustanovka; reaction engine-bomb installation & Смерч; waterspout) is a anti-submarine rocket launcher. The weapon system is remotely similar to the British Hedgehog anti submarine mortar launcher from the Second World War.
The system is very light and was developed in 1955 especially for smaller vessels. It can not be swiveled horizontally, it is targeted with the entire ship, which is a serious disadvantage of the weapon system.
The RBU-1200 has five launcher pipes in one system. Reloading is done manually.
The system is controlled by a PUS-B "Uragan" fire control system.
The system is designed to destroy submarines and torpedoes.
Ammunition RGB-12 uses contact fuzes. The launch is made of solid rocket fuel, the flight itself is ballistic arc with a long range from 400 to 1200 meters. The contact lighter K-3, K-3M, or combined contact-remote lighter KDV is used as a lighter. Lighter K-3 / K-3M activates the warhead in direct hit target (or impact on the bottom), KDV lighter outside impact on the target (bottom) in the range of 25-330 meters can also be set to activate when reaching the specified depths in the range 10-330 meters.[1]
