The AI-222-25 (Ukrainian: AI-222-25) are low-bypass turbofan engines of the AI-222 family.

Design and development

The development of the engine started at Ivchenko-Progress of Zaporizhia, Ukraine in 1999. The engine was originally intended for the Yakovlev Yak-130 trainer aircraft. An after-burning version, the AI-222-25F (from Ukrainian "Форсаж", meaning reheat) is also available with thrust vectoring.
