Kuznetsov NK-32
The Kuznetsov NK-32 is a military specification afterburning 3-spool low bypass turbofan jet engine which powers the Tupolev Tu-160 supersonic bomber, and was fitted to the later model Tupolev Tu-144LL supersonic transport. It is the largest and most powerful engine ever fitted on a combat aircraft (however, higher thrust engines are fitted to civil aircraft such as General Electric GE90. Such engines sacrifice exhaust speed for higher thrust and hence cannot accelerate to supersonic speeds).
It produces 55,000 lbf (245 kN) of thrust in maximum afterburner.
The derivation type is an NK-32 Tier 2 except for Afterburner, it is mounted to the PAK DA.[1]
