S-300V , "Antey-300V" ( GRAU index : 9K81 ) is a series of Soviet and Russian universal, multi-channel anti-aircraft missile systems of medium range for air / missile defense of the front line of the ground forces. It was developed as part of the creation of the unified S-300 air defense system since 1969 , to replace the 2K11 Krug air defense system in the ground forces. It was fully adopted for service in 1988. (My custom made model, may not be super accurate but its the best free option on the market as of 20/04/2026)
