The Su-25 (NATO reporting name 'Frogfoot') is a battlefield attack, close air support, and anti-tank aircraft designed by the Soviet Union. It remains in service with Russia and the CIS, as well as a variety of export customers.
Development
The Su-25 was designed by Sukhoi as a result of studies in the late 1960s on an aircraft to fill the Shturmovik ground attack role (so-named after the famous Ilyushin Il-2 of World War II renown). It is comparable to the A-10 Thunderbolt II, although it more closely resembles the Northrop YA-9, which lost the USAF competition that produced the A-10. (The same requirement led to the development of fighter bomber versions of the Mikoyan-Gurevich MiG-23, culminating in the definitive MiG-27, although those aircraft share nothing with the Su-25 in design.)
The Su-25 made its first flight in 1979. The Frogfoot is heavily armed, with a Gryazev-Shipunov GSh-30-2 30mm cannon and various air-to-ground munitions; it can carry more than 4,000 kg of weaponry in the ground-attack role. It is also very tough, and provides the pilot with a lot of protection.
The Su-25, which is called Grach (rook) in CIS service, was heavily used by the Soviet Union during its operations in Afghanistan in the 1980s. Many were lost to shoulder-launched SAMs in combat.
Some two-seat Su-25UB trainers were built, including a small number for the AVMF designated Su-25UTG. They had strengthened airframes and an arresting hook for practicing aircraft carrier landings. The first Su-25UTG flew in September 1988, and about ten were produced. About half remain in Russian service, used with Russia's sole carrier, the Admiral Kuznetsov. The Russian navy ordered ten more Su-25UBP aircraft, much like the earlier Su-25UTG, but with a retractable aerial refueling probe.
More advanced attack variants, the Su-25T (alternatively, Su-34, although the OKB appears to have given that designation to the 'Flanker' derivative) and later Su-25TM (Su-39), were developed with an improved nav/attack system, better survivability, and capability of carrying new precision-guided weapons. Only a handful of each version has been produced.
The Su-25 is no longer in production, but it is still flown by the air forces of Afghanistan, Angola, Azerbaijan, Belarus, Bulgaria, Czech Republic, Ethiopia, Georgia, Iran, Iraq, Kazakhstan, Republic of Macedonia, North Korea, Peru, Russia, Slovakia, and Ukraine. Until recently, Côte d'Ivoire's air force owned 2 Su-25s before they were destroyed in a French neutralisation of the threats towards peacekeepers there.
