Work on creating an attack aircraft to replace Su-25 was started in 1984. The first project was ready by 1989. The theme was called Sturmovik-90. One of the options developed in Sukhoi Design Bureau received the T-12 index. It was a very unusual car. The plane had a carrying body with two cabins between which the channels air intake s were located, with forward-swept wings. At their ends were placed containers with EW equipment. In the left cockpit there was a pilot and under the radio transparent fairing there was a radar, and in the right cockpit Weapon Operator was located and under the fairing there was an optical-electronic system.[1] Weapons Armament is mainly located in two internal compartments. Although it was possible to place additional weapons on the underwing pylons. Work on the T-12 took place at a very serious pace and the assembly line at the plant in Irkutsk was being prepared, but the events of the nineties put an end to this project. Flight performance Estimated take-off weight was about 20 tons, engine thrust (both single- and twin-engine variants were considered) —about 100 kN. The length of the aircraft - 16 m, wingspan - 19.5 m. Fuel capacity - 4500 kg, combat load - 6500 kg. Maximum speed - 1000 km / h, cruising - 835 km / h.
