# Russian Citadel anti-aircraft system development > Developing situation record from CLSTR: https://clstr.news/situations/russian-citadel-anti-aircraft-system-development > Updated: 2026-11-06T07:06:19.000Z. Sources: 4. Developments: 2. Russia has introduced the Citadel, a new anti-aircraft missile system designed to intercept cruise missiles, strike drones, and heavy unmanned aerial vehicles. The system can function as a standalone unit or within a multi-layered air defense network. It features automated target recognition and trajectory calculation, with the ability to self-correct its aim if an initial projectile misses. Following the initial unveiling, the state corporation Rostec developed a mobile configuration of the Citadel, also known as the ZAK-30. This version integrates the combat module, radar, and optical detection systems onto a vehicle chassis to enable faster relocation. The mobile system utilizes 30mm automatic guns and specialized shrapnel-filled projectiles with remotely controlled fuses to engage maneuverable drones and missiles by creating a cloud of fragments. Rostec claims the system is more ammunition-efficient than standard weapons, though the company has not released independently verified performance data. ## Timeline ### 2026-11-06: Rostec develops mobile version of Citadel anti-aircraft system Russia's Rostec has created a mobile version of the Citadel ZAK-30 anti-aircraft system, mounting its radar and 30mm cannons on a vehicle to better defend against drones and cruise missiles. 4 sources. https://clstr.news/cluster/rostec-develops-mobile-version-of-citadel-anti-aircraft-system ### 2026-10-21: Russia unveils Citadel anti-aircraft missile system Russia has unveiled the ‘Citadel’ anti-aircraft missile system, capable of intercepting drones and cruise missiles. 2 sources. https://clstr.news/cluster/russia-unveils-citadel-anti-aircraft-missile-system --- Cite as: Russian Citadel anti-aircraft system development.
