RBU-6000 was designed as a 213 mm caliber anti-submarine rocket launcher. It is similar in principle to the Royal Navy Hedgehog system used during the Second World War. It consists of a horseshoe-shaped arrangement of twelve launch barrels, that are remotely directed by the Burya fire control system.
RBU-6000 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 for shore bombardment.
