Design and development
The development of the engine started at Ivchenko-Progress of Zaporizhzhia, Ukraine in 1999. The engine was originally intended for the Yakovlev Yak-130 trainer aircraft. An after-burning version, the AI-222-25F (from Russian/Ukrainian "Форсаж", meaning reheat) is also available with thrust vectoring. In 2015 Russian manufacturer "Saljut" began to produce AI-222-25 without any Ukrainian involvement.[1]
