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

T90S: Export version of the T90, later adopted by the Russian Armed Forces as the T90A. 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 Shtora1 passive, active protection system which lacks the infrared dazzlers carried on the turret. These were initially supplied with cast turrets of the early T90, and when stocks were depleted, new, welded turrets were fabricated.
