The Fencer is no longer in production and the air force intends to replace the aircraft in certain roles with the Su-27IB (Su-34). Some 900 Su-24 Fencers were produced for the Soviet air force.
The latest development of the Su-25, the Su-25TM, is now under development, and is a further modification of the Su-25T. Two or three prototype Su-25TM aircraft have been completed.
China has ordered 50 Su-27s and has reached an outline agreement with Russia on eventual licence production of the aircraft. The initial batch of 26 aircraft has entered service, with deliveries of the second order believed to be completed by mid-1996. This is the first export deal for the type, re-opening CIS weapons sales to China after 30 years.
The first a navalised Su-27K (T-10K), with moveable foreplanes, folding wings and tailplane, strengthened landing gear and an arrestor hook is now working up.
Sukhoi's Su-27M (T-10M) programme is intended effectively as a mid-life update to the basic Flanker. The latest prototype to be shown publicly, aircraft 711, was fitted with thrust-vectoring nozzles.
The Su-30 (T-10PU) is intended to provide the Su-27 with a fighter-controller aircraft, capable of handing off targets to other aircraft via a datalink. Sukhoi is also developing the Su-30MK, a multi-role development of the Su-30, for the export market.
The Sukhoi Su-27IB (Istrebitel-bombardirovschik-fighter bomber), the side-by-side two-seat variant of the Flanker Interceptor, was first exhibited at Minsk in February 1992. At least four aircraft are being flown, with several more under construction. The airframe is also likely to form the basis of both Su-27R reconnaissance and Su-27IBP fighter-bomber/jammer projects.
