The '''RBU-6000''' '''Smerch-2''' (Реактивно-Бомбовая Установка, ''Reaktivno-Bombovaja Ustanovka''; [[reaction engine|rocket]]-bomb installation & Смерч; waterspout) is a 213 mm caliber [[Soviet Union|Soviet]] [[antiAnti-submarine weapon]] [[multiplemortar#Anti-submarine rocket|anti-submarine launcher|rocket launcher]]. It is similar in principle to the [[Royal Navy]] [[Hedgehog (weapon)|Hedgehog]] system used during the [[Second World War]]launcher. The system entered service in 1960-611960–1961 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]] rockets, which carry unguided [[depth chargescharge]]s. 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 afor shore bombardment system.

The '''{{vanchor |RPK-8}}''' system is an upgrade of the RBU-6000 system, firing the 90R rocket, which releases a 90SG depth charge that is actively guided in the water.<ref name=roe-rpk/> This allows it to home in on targets at depths of up to {{convert|1,000 meters|m|ft}}. The warhead is a {{convert|19.5&nbsp;|kg|lb|adj=on}} [[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. RPK-8 entered service in 1991 and mounted on Project 1154 and 11356 frigates. Serial production of the upgraded 90R1 rocket was launched in 2017.
