Russia’s Central Military Command receives 15 upgraded MBTs, heading into the Ukrainian war

T-90S: Export version of the T-90, later adopted by the Russian Armed Forces as the T-90A. These tanks were made by Uralvagonzavod and were updated with 1,000 hp (750 kW) engines made by Chelyabinsk Tractor Plant. These tanks carry a leaner version of the Shtora-1 passive/active protection system which lacks the infra-red dazzlers carried on the turret. These were initially supplied with cast turrets of the early T-90, and when stocks were depleted, new, welded turrets were fabricated.
