"Air defense units of the Southern Military District armed with S-300 and S-400 air defense systems have detected, monitored and destroyed target drones imitating adversary aircraft, cruise missiles and unmanned aerial vehicles during snap drills at the Ashuluk testing range [in the Astrakhan region]," the ministry said in a statement.
According to the statement, the S-300 and S-400 units have carried out over 30 missile launches at targets flying at varying speeds and at altitudes between extremely low and up to five kilometers (some 16,500 feet).
Russia launched on August 25 snap combat readiness inspections, involving units of Southern, Western and Central military districts, the Northern Fleet, the Aerospace Forces and the Airborne Troops. The drills will continue through August 31.
