As the JSF program moved into the System Development and Demonstration phase, the X-35 demonstrator design was modified to create the F-35 combat aircraft. The forward fuselage was lengthened by 5 inches (13 cm) to make room for mission avionics, while the horizontal stabilizers were moved 2 inches (5.1 cm) aft to retain balance and control.
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.

The F-35 Lightning II uses the Rolls-Royce LiftSystem, in which 29,000 hp [14] [15] [16] is diverted forward through a driveshaft from the engine's low-pressure (LP) turbine via a clutch [17] and bevel-gearbox to a vertically mounted, contra-rotating lift fan located forward of the main engine.
Based on wind tunnel testing, Lockheed Martin slightly enlarged its X-35 design into the F-35. The forward fuselage is 5 inches (130 mm) longer to make room for avionics. Correspondingly, the horizontal stabilators were moved 2 inches (51 mm) rearward to retain balance and control. The top surface of the fuselage was raised by 1 inch (25 mm ...
