Engagement and Fire Control Radars (SBand, Xband)
First introduced in 1982, the Tunguska series of hybrid SPAAG/SAM systems was deployed by the PVOSV to provide a replacement for the legacy ZSU234P, which despite its success in Vietnam and the Middle East, was recognised as vulnerable to the then new A10 Thunderbolt, and to helicopters firing antiarmour missiles, such as the Hellfire equipped AH64A Apache.
