The Kuznetsov NK-25 is a turbofan engine used in the Tupolev Tu-22M strategic bomber. It can equal the NK-321 engine as one of the most powerful supersonic engines in service today. It is rated at 245 kN (50,000 lbf) thrust. The three shaft engine we call the NK-25 was designed in the years 1972-1974. It was superior to many other engines because of it's improved fuel economy. It is made by the Soviet Kuznetsov Design Bureau.
