The T-90 is a deep modernization of the T-72B, created in Nizhny Tagil in 1989. The T-90A (Object 188A) is a development of the T-90 tank and a prototype of the serial version of the T-90A. The tank uses a new type of small-link caterpillars, a welded turret similar to the 187 object turret, a different engine (V-92S2), a thermal imaging system, and a deep fording system.
