Variants
Su-25The basic version of the aircraft was produced at Factory 31, at Tbilisi, in the Soviet Republic of Georgia. Between 1978 and 1989, 582 single-seat Su-25s were produced in Georgia, not including aircraft produced under the Su-25K export program.[1]
Su-25KThe basic Su-25 model was used as the basis for a commercial export variant, known as the Su-25K (Komercheskiy). This model was also built at Factory 31 in Tbilisi, Georgia.[1]
Su-25UBThe Su-25UB trainer (Uchebno-Boyevoy) was drawn up in 1977. The first prototype, called "T-8UB-1", was rolled out in July 1985 and its maiden flight was carried out at the Ulan-Ude factory airfield on 12 August of that year.[1]
Su-25UBKFrom 1986 to 1989, in parallel with the construction of the main Su-25UB combat training variant, the Ulan-Ude plant produced the so-called "commercial" Su-25UBK, intended for export to countries that bought the Su-25K, and with similar modifications to that…[1]
Su-25UBMThe Su-25UBM is a twin-seat variant that can be used as an operational trainer, but also has attack capabilities, and can be used for reconnaissance, target designation, and airborne control.[1]
Su-25UTGThe Su-25UTG (Uchebno-Trenirovochnyy s Gakom) is a variant of the Su-25UB designed to train pilots in takeoff and landing on a land-based simulated carrier deck, with a sloping ski-jump section and arrester wires.[1]
Su-25BMThe Su-25BM (Buksirovshchik Misheney) is a target-towing variant of the Su-25 whose development began in 1986. The prototype, designated T-8BM1, successfully flew for the first time on 22 March 1990, at Tbilisi.[1]
Su-25TThe Su-25T (Tankovy) is a dedicated antitank version, which has been combat-tested with notable success in Chechnya. The design of the aircraft is similar to the Su-25UB.[1]

Summary

The Su-39 Frogfoot is a derivative of the Su-25 Frogfoot . It resulted in part from the lessons learned in combat by the Su-25 in Afghanistan. However, significant changes have been made not only in capabilities but also in performance, making it effectively a different aircraft.
