Russia's new Tor-M2U anti-aircraft missile defense systems have arrived in Siberia's Eastern Military District.

The system arrived at a tank formation stationed in the Buryatia republic, Russia's Tass news agency reported.

The tank formation's air defense units had undergone retraining to qualify to work with the new system, studying the equipment, tactical and technical characteristics while learning to load the launcher and search and detect air targets.

Russia's Ministry of Defense said in March that air defense units had carried out the first Tor-M2U firings at the Telemba specialized range in Buryatia.

The system detected, tracked and identified small-sized aerial target simulators.

Tor-M2U is the next generation off the Tor short-range air defense series, and is designed to protect military and state facilities from warplane and helicopter strikes by cruise missiles, guided missiles, glide and guided aerial bombs and drones.

The combat vehicle can engage and track four targets at once, Tass reported, and cited prior district reports stating the latest system will replace the Osa-AK air defense system.
