The F-16C/D Block 30/32s were the first to be built with the common engine bay, able to accept the existing F100-200/220 engine (Block 32) or the F110-100 (Block 30). A non-afterburning variant, the F100-PW-220U powers the Northrop Grumman X-47B UCAV. The -100 and -200 series engines could be upgraded to become equivalent to -220 specifications ...
The Pratt & Whitney F135 is an afterburning turbofan developed for the Lockheed Martin F-35 Lightning II, a single-engine strike fighter.It has two variants; a Conventional Take-Off and Landing variant used in the F-35A and F-35C, and a two-cycle Short Take-Off Vertical Landing variant used in the F-35B that includes a forward lift fan.

Turbofan engines with a bypass ratio of less than 2 (usually less than 1). These engines were commonly used on narrow body jet airliners of the 1960s and 1970s, some business jets from the same time period, and on modern fighter aircraft.
To date, Pratt & Whitney has delivered over 1,200 F135 engines, accumulating more than 900,000 flight hours.
The familiar study of jet aircraft treats jet thrust with a "black box" description which only looks at what goes into the jet engine, air and fuel, and what comes out, exhaust gas and an unbalanced force. This force, called thrust, is the sum of the momentum difference between entry and exit and any unbalanced pressure force between entry and ...
The General Electric/Rolls-Royce F136 was an afterburning turbofan engine being developed by General Electric, Allison Engine Company, and Rolls-Royce (Allison was subsequently acquired by Rolls-Royce) as an alternative powerplant to the Pratt & Whitney F135 for the Lockheed Martin F-35 Lightning II. The two companies stopped work on the ...
General Electric and Pratt & Whitney are fighting over the next F-35 engine. It's the most expensive defense program in history, so the stakes are high. The Messy Battle to Build the F-35's Next ...
The engine delivers thrust in the 35,000 lbf (156 kN) class and was designed for sustained supersonic flight without afterburners, or supercruise. Delivering almost 22% more thrust with 40% fewer parts than its F100 predecessor, the F119 allows the F-22 to achieve supercruise speeds of up to Mach 1.8.
