First generation (Su-25)
In 1968, the USSR launched a program intended to equip its air force with a close support aircraft (Close Air Support) capable of intervening directly on the battle front, which presupposed great maneuverability and good ability to take shots. Subsonic speed was considered sufficient. The Sukhoi constructor was working on a project designated internally as T-8, which underwent a few modifications (more powerful reactors, increased load carried, etc.) before being declared the winner of the competition.

The first prototype made its maiden flight onFebruary 22, 1975, powered by two Tumanski R-95Sh reactors of 4,500  kg /p each. It was a version without afterburner of the MiG-21 engine , which had imposed itself as a replacement for the Mikulin RD-9 initially planned thanks to its superior power and its recognized reliability. A second prototype took off at the enddecember 1975with some changes, such as a 30  mm gun instead of the 23  mm gun , airbrakes, and modified ailerons. The avionics were largely borrowed from the Su-17/Su-20 , while the laser system placed in the nose was close to that of the MiG-27 .

The first production aircraft left the factory in 1979. In 1980, two copies were sent to Afghanistan to assess their capabilities. They carried out about a hundred test flights, including 40 to 50 real attack missions. Deliveries to operational units began in 1981. During production, the R-95Sh reactor was replaced by an R-195 of equivalent power but capable of withstanding more damage. The experience of the missions in Afghanistan led to the installation of a firewall between the two reactors, a fire extinguisher system and decoy launchers.

A two-seat Su-25UB version intended for training, but retaining combat capabilities, was ordered in the late 1970s. The prototype made its first flight onAugust 10, 1985and mass production began the following year. Sukhoi derived from it a Su-25UTG version intended for the training of pilots of the Russian naval aviation , devoid of any armament but equipped with a landing gear and with a reinforced structure.
