S-300 Russian Air Defence Missile System

The S-300 (NATO reporting name SA-10 Grumble) is a series of long range surface-to-air missile systems belonging to the former Soviet Union, now held by Russia as well as various former Eastern Bloc countries. It was produced by NPO Almaz, based on the initial S-300P version. The S-300 system was developed to defend against air raids and cruise missiles for the Soviet Air Defence Forces. Subsequent variations were also developed to be able to intercept ballistic missiles. The S-300 system was first deployed by the Soviet Union in 1979, designed for the air defence of large industrial and administrative facilities, military bases and control of airspace against enemy strike aircraft. The system is fully automated, though manual observation and operation are also possible. Components may be near the central command post, or as distant as 40 km. Each radar provides target designation for the central command post. The command post compares the data received from the targeting radars up to 80 km apart, filterin
