As we reported yesterday #Russia is testing a stationary version of the “Citadel” ("Цитадель") anti-aircraft artillery system with a 100-mm gun The anti-aircraft gun is expected to be equipped with 100-mm “smart” shells with programmable airburst by range. The new version of “Citadel” may increase the engagement altitude against drone-type targets to 7 km. Thus, high-altitude Ukrainian Armed Forces drones can be countered without using expensive missiles.
