SS-N-12 Sandbox

SS-N-12 Sandbox is a Russian supersonic speed cruise missile with a range of 550 km carrying a payload of 1,000 kg. The P-350 Bazalt [industrial code 4K-77] was the successor to the P-35 Bazalt, which was started in 1963 and subsequently cancelled. It evolved into the P-500 Bazalt [industrial code 4K-80] which was the production version of the original P-350 Bazalt. Developed to replace the SS-N-3 Shaddock anti- ship missile, it was initially deployed on Kiev-class aircraft carriers in the mid-1970s. The Slava-class cruisers carry an advanced version with an improved sophisticated guidance system, an autopilot that can be programmed for mid-course maneuvers, and an enhanced engine. The P-700 Granat [SSN-19 Shipwreck] was developed as a more successful turbojet alternative to the SSN-12 Sandbox, from which it was derived.
