The Metel Anti-Ship Complex (Russian: противолодочный комплекс «Метель» 'Snowstorm'; NATO reporting name: SS-N-14 Silex) is a Soviet family of anti-submarine missiles.

The missile carries an underslung anti-submarine torpedo which it drops immediately above the suspected position of a submarine.

In the early 1960s the Soviet Union introduced the RBU-6000 and RBU-1000 anti-submarine rocket launchers, which worked on a similar principle to the Royal Navy's Hedgehog system of the Second World War, propelling small depth charges up to 5,800 metres (6,300 yd) from a ship.

In 1963 the US Navy introduced ASROC, a missile that flew to the estimated position of the target submarine, and then dropped a torpedo into the water to destroy it.

The later 'Rastrub' models of the weapon were "universal" carrying a UGMT-1 multi-purpose torpedo and in addition had 185 kg (408 lb) shaped charge warhead for use against ships guided by radio command and infrared seeker.
