The Tunguska air defense system is a Russian weapon that was made to safeguard against various aerial threats, including helicopters, aircraft, drones, and cruise missiles. It has a mix of surface-to-air missiles and guns, and is intended to be mobile and adaptable, allowing it to be set up quickly in various environments. The system was created in the late 1970s and early 1980s by the Tula Design Bureau of Instrument Engineering and is named after the Tunguska River in Siberia, where a meteorite impact happened in 1908. The Tunguska was developed as a replacement for the 2K12 Kub, which was a successful air defense system from the 1950s and 1960s.
