The T-90 has its origins in a Soviet-era program aimed at developing a singular replacement for the T-64, T-72 and T-80 series of main battle tanks. The T-72 platform was selected as the basis for the new generation of tank owing to its cost-effectiveness, simplicity and automotive qualities. The Kartsev-Venediktov Design Bureau from Nizhny Tagil was responsible for the design work and prepared two parallel proposals - the Object 188, which was a relatively simple upgrade of the existing T-72B tank (Object 184), and the far more advanced Object 187 - only vaguely related to the T-72 series and incorporating major improvements to the hull and turret design, armor, powerplant and armament.
