Mechanics actuating an F-16 exhaust nozzle.The powerplant first selected for the single-engined F-16 was the Pratt & Whitney F100-PW-200 afterburning turbofan, a slightly modified version of the F100-PW-100 used by the F-15. Rated at 23,830 lbf (106.0 kN) thrust, it remained the standard F-16 engine through the Block 25, except for new-build Block 15s with the Operational Capability Upgrade (OCU). The OCU introduced the 23,770 lbf (105.7 kN) F100-PW-220, which was also installed on Block 32 and 42 aircraft; while not offering a noteworthy difference in thrust, it introduced a Digital Electronic Engine Control (DEEC) unit that improved reliability and reduced the risk of engine stalls (an unwelcome occasional tendency with the original "-200" that necessitated a midair engine restart). Introduced on the F-16 production line in 1988, the "-220" also supplanted the F-15’s "-100," thereby maximizing commonality. Many of the "-220" jet engines on Block 25 and later aircraft were upgraded from mid-1997 to the "-220E" standard, which further enhanced reliability and maintainability, including a 35% reduction of the unscheduled engine removal rate.[23][33][62][63]
Development of the F100-PW-220/220E was the result of the USAF’s Alternate Fighter Engine (AFE) program (colloquially known as “the Great Engine War”), which also saw the entry of General Electric as an F-16 engine provider. Its F110-GE-100 turbofan, however, required modification of the F-16’s inlet; the original inlet limited the GE jet’s maximum thrust to only 25,735 lbf (114.5 kN), while the new Modular Common Inlet Duct allowed the F110 to achieve its maximum thrust of 28,984 lbf (128.9 kN) in afterburner. (To distinguish between aircraft equipped with these two engines and inlets, from the Block 30 series on, blocks ending in "0" (e.g., Block 30) are powered by GE, and blocks ending in "2" (e.g., Block 32) are fitted with Pratt & Whitney engines.)[35][62][64][65][66]
