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).
