Russia’s unique forward-swept wing jet trainer SR-10 is passing tests with the Russian Aerospace Forces in the Moscow Region.
The plane’s name can be explained as “jet with wing sweep —10°”, which reflects the aircraft’s main constructional feature — the moderately forward-swept wings facilitating stability and maneuverability at low speeds.
This subsonic, single engine, all-composite plane meets the needs of unexperienced pilots who will later change it for the Yak-130 — a sophisticated trainer which is in fact a full-fledged combat plane wanted by a number of countries for their air forces.
In contrast with the Yak-130, the SR-10 is more economically feasible for practice.
The plane, manufactured by Russian private design bureau “Modern Aviation Technologies,” hit the skies for the first time in December.
Its K-93 catapult seats can eject pilots at zero altitude at a speed of 950km/h.
Another Russian forward-swept wing plane, the Su-47 (S-37) Berkut, was a promising next-generation fighter which became a flying lab. It has served as a platform for testing advanced technologies later implemented in the T-50 PAK FA fifth-generation aircraft.

KB SAT SR-10
The KB SAT SR-10 is a prototype Russian single-engine jet trainer aircraft, fitted with a single forward-swept wing. It first flew in 2015, and is being offered to the Russian Air Force and for export.
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 a Ivchenko AI-25V fitted in the prototype, but more modern Russian engines, such as the NPO Saturn AL-55 are 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 proposed turboprop trainer. Despite this setback, KB SAT continued to develop the SR-10, proposing it as an intermediate trainer between the Yak-152 and the Yakovlev Yak-130 advanced trainer and for export. The first prototype SR-10 made its maiden flight on 25 December 2015.
