The KB SAT SR-10 is a Russian single-engine jet trainer aircraft, fitted with forward-swept wings. It was being offered to the Russian Air Force and for export. The design bureau KB SAT (Sovremyenne Aviatsyonne Tekhnologii - Modern Aircraft Technologies) began work on a single-engine jet trainer in 2007. The first and only prototype SR-10 made its first flight on 25 December 2015. In September 2018, the Russian government failed to allocate funds to start production of SR-10 and as a result KB SAT suspended all work on the project.
