The S-300 (NATO reporting name SA-10 Grumble) is a series of long-range surface-to-air missile systems developed by the former Soviet Union. It was produced by NPO Almaz for the Soviet Air Defence Forces to defend against air raids and cruise missiles.
It is used by Russia, Ukraine, and other former Eastern Bloc countries, along with Bulgaria and Greece. It is also used by China, Iran, and other countries in Asia.
The system is fully automated, though manual observation and operation are also possible.[5] Each targeting radar provides target designation for the central command post. The command post compares the data received from the targeting radars and filters out false targets. The central command post has both active and passive target detection modes.[6][7] Missiles have a maximum range of 40 kilometres (25 mi) from the command post.
