The ZSU-23-4 Shilka (named after a Russian river) is an effective, combat-proven, air defence artillery system mounting four liquid-cooled 23mm 2A7 cannon. The Shilka can engage targets with a fully-integrated, radar-guided, automatic target acquisition, tracking and ranging system with backup visual sights.

During the 1967 and 1973 wars the IDF captured over 60 ZSU-23-4 Shilka anti-aircraft vehicles and put them back into service with their air defence battalions.
