Russia Air Force have begun flight tests on new SR-10 training aircraft, developed by a private Russian design bureau KB SAT, in Kubinka air base in Moscow region.

The SR-10 is a mid-wing monoplane of all-composite construction, with a wing swept forward at an angle of 10 degrees for improved stability at low speeds, hence the name SR-10. The aircraft seats two airmen, powered by a single turbofan engine and can reach up to 900 km/h (559 mph). 

Military experts have claimed that Russia faces a shortage of flight training aircraft, there should be no less than 300 aircraft. With the development of SR-10, the air force is trying to cope with the issue.
