The T-90 is a Soviet third-generation main battle tank that is essentially a modernisation of the T-72, incorporating many features of the T-80. It is currently the most modern tank in service with the Soviet Army and Soviet Naval Infantry. Although a development of the T-72, the T-90 uses a 125mm 2A46 smoothbore tank gun, 1G46 gunner sights, a new engine, and thermal sights. Standard protective measures include a blend of steel, composite armour, smoke mortars, Kontakt-5 explosive-reactive armor, laser warning receivers, Nakidka camouflage and the Shtora infrared ATGM jamming system. The EMT-7 electromagnetic pulse (EMP) creator has been used in testing but not fitted to T-90s in active service. It is designed and built by Uralvagonzavod, in Nizhny Tagil, Russian SFSR. Since 2011, the Russian armed forces have ceased ordering the T-90, and are instead waiting for the development of the Universal Combat Platform T-99 that is expected to enter service in 2020.
