TYPE: Advanced jet trainer.
PROGRAMME: Announced in December 2002, when Su-52UTS revealed to be under study as single-engined design with forward-swept wings intended to come between Su-49 and combat-training Yak-130 in pilot instruction course. Unit cost 11/2 to two times cheaper than Yak-130; operating cost less than US$1,000 per hour.
In May 2003, it was reported that Russian Air Forces was preparing to launch a competition for such an aircraft. However, this had not been announced by late 2003, at which time Sukhoi revealed that development work had ended short of a design able to participate in any competition.
