The main drawback of T-72 tanks of all modifications, compared to other cars of the Soviet and foreign production of those years was the lack of an automated fire control system (FCS). In this regard, it was decided to conduct a deep modernization “semdesyatdvoyki.” This work took place under the theme “improving the T-72B” defined by the Council of Ministers of the USSR of June 19, 1986. The original design took place under the leadership of V. N. Venediktov, and after his 1987 retirement – under the leadership of new chief designer V. I. Potkin.
When developing the new machine, which received the designation “object 188”, focused on improving combat effectiveness with the aim to bring it to the level of the T-80U. The latter borrowed the complex weapons control 1А45 “Irtysh”, which was revised to interact with the autoloader Nizhny Tagil design received the designation 1А45Т. In January 1989, four prototypes of “object 188” was presented on state tests, during which the car a year and a half ran in the Moscow, Kemerovo and Zhambyl (Kazakhstan) regions, as well as on the ground of “Uralvagonzavod” (UVZ). The tank was tested in the maximum modes, has passed 14 thousand km (that is, a full cycle overhaul) with virtually no breakdowns and failures.
