The Russian company “Rostec” has unveiled a new mobile version of the “Citadel” anti-aircraft complex. The ZAK-30 system is designed to destroy drones and protect critical infrastructure from air attacks. The key feature of the complex is its special “smart” projectiles, which allow for fewer ammunition to be used to engage targets. Furthermore, thanks to its installation on a vehicle chassis, the “Citadel” can quickly change positions and operate as part of mobile fire groups.
