Kuznetsov NK-25
Kuznetsov NK-25 is a three-shaft afterburning turbofan developed for the Tu-22M3. UEC records 25,000 kgf thrust and a 1.45 bypass ratio, and states that the engine operates as part of the Tu-22M3 powerplant. This propulsion record does not assert a broader aircraft installation set or lifecycle beyond the cited UEC evidence.

- Note
- Official UEC-Kuznetsov history records NK-25 production beginning in 1972, 25,000 kgf thrust (normalized here to 245.17 kN afterburning thrust), three-shaft afterburning turbofan architecture, a 1.45 bypass ratio, and operation in the Tu-22M3 powerplant; it does not establish a broader installation set or lifecycle state.
