The T-90 has its origins in a Soviet-era program aimed at developing a single replacement for the T-64, T-72 and T-80 series of main battle tanks. It entered service with the Russian Army in 1992. The T-90 was designed and built by Uralvagonzavod, in Nizhny Tagil, Russia. Standard protective measures include a blend of steel and composite armour, smoke grenade dischargers, Kontakt-5 explosive reactive armour (ERA) and the Shtora infrared anti-tank guided missile (ATGM) jamming system. It uses a 125 mm 2A46 smoothbore main gun, the 1A45T fire-control system, an upgraded engine, and gunner's thermal sight. The T-90 is a third-generation Russian main battle tank developed to replace the T-72.
