The ZSU-23-4 Shilka is a lightly armored, self-propelled, short-range 3D radar-guided anti-aircraft weapon system. By four 23 mm cannons, it destroys air targets, such as planes, helicopters or UAVs. It can also engage ground targets. According to the customer's request, we can add an optical system within the vehicle, from a basic camera for target confirmation to a complex system   replacing a 3D radar, a short-range anti - aircraft missile system, a UAV jammer, and also modernize the engine and gearbox.
