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.

Both cells can accommodate engines that produce up to 70,000 pounds of thrust. In recent years, SL-2 has tested the F100 engine for the F-15 Eagle, F-16 Fighting Falcon, and the F119 engine for the F-22A Raptor. SL-3 has also tested the Pratt & Whitney F100 engine, as well as the Pratt & Whitney F135 engine for the F-35. [1]
F-35A weighs 13.3t,and max thrust of F135 is 19.5t. The thrust-to-weight ratio of Al-41 is 8.8 and that of F135 is just 6.7 under the current entries. But the thrust-to-weight ratio of Su-35 is JUST 2×14÷19≈1.47，and that of F-35A is 1×19.5÷13.3≈1.47. This may be caused by the difference in engine weight standards between the two sides.
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.
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 ...
