The Russian design bureau KB SAT (
Sovremyenne Aviatsyonne Tekhnologii – Modern Aircraft Technologies) began work on a single-engine jet trainer and sport aircraft, the SR-10, in 2007, displaying a mockup at the
MAKS airshow at
Zhukovsky in August 2009. The SR-10 is a mid-wing
monoplane of all-
composite construction, with a wing swept forward at an angle of 10 degrees. The crew of two sit in a tandem cockpit. It is powered by a single turbofan, with an
Ivchenko AI-25V AI25TSR (modification of AI25TL) fitted in the prototype, but more modern Russian engines, such as the
NPO Saturn AL-55 were proposed for production aircraft. The SR-10 was offered to meet a 2014 requirement for a basic trainer for the Russian Air force, but was rejected in favour of the
Yakovlev Yak-152, a piston-engined trainer. Despite this setback, KB SAT continued to develop the SR-10, proposing it as an intermediate trainer between the Yak-152 and the
Yak-130 advanced jet trainer and for export. The first prototype SR-10 made its maiden flight on 25 December 2015. In September 2018, according to media reports, the Russian government failed to allocate funds to start production of SR-10 for the
Russian Air Force and as a result KB SAT suspended all work on the project. On September 19, 2020, SR-10 took part in the "Russian Aviation Race", held at the Oreshkovo airfield (
Kaluga oblast) ==Specifications (SR-10) ==
