 The initial powerplant selected for the single-engined F-16 was the Pratt & Whitney F100-PW-200 afterburning turbofan, a modified version of the F-15's F100-PW-100, rated at 23,830 lbf (106.0 kN) thrust.During testing, the engine was found to be prone to compressor stalls and "rollbacks", wherein the engine's thrust would spontaneously reduce to idle.Until resolved, the Air Force ordered F-16s to be operated within "dead-stick landing" distance of its bases.
