According to the functionary, the design bureau specialists are working on the creation of a power plant that could be installed on the aforementioned fighters without modifying the airframe. The order for the development came from the RF Ministry of Defense. The military department believes that such an approach in the future could significantly reduce costs.
As for the characteristics of the promising engine, they have not yet been disclosed. It is only known that the basis of the new unit will include the units of the two-shaft by-pass turbojet AL-41F-1C and other power plants in operation.
