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. [ 1 ] [ 2 ] The F119's nozzles incorporate thrust vectoring that enable them to direct the engine thrust ±20° in the pitch axis to give the F-22 enhanced maneuverability.
The Lockheed Martin/Boeing F-22 Raptor is an American twin-engine, all-weather, supersonic stealth fighter aircraft.As a product of the United States Air Force's Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also incorporates ground attack, electronic warfare, and signals intelligence capabilities.
The AN/APG-77 system itself exhibits a very low radar cross-section, supporting the F-22's stealthy design. [3] The upgraded APG-77(V)1 may have an even greater range. Much of the technology developed for the APG-77 was used in the AN/APG-81 radar for the F-35 Lightning II , and in turn the technology from the APG-81 was applied to the upgraded ...
Arthur Tomassetti has said that the F-35 is a "software intensive airplane and software is easy to upgrade, as opposed to hardware." [22] In order to ease the addition of new software features, the F-35 has adopted a kernel and application separation of security responsibilities. [23]
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.

After a competition between the Boeing X-32 and the Lockheed Martin X-35, the latter aircraft was selected for a contract award and developed into the F-35 Lightning II, which will replace various tactical aircraft, including the US F-16, A-10, F/A-18A-D, AV-8B, EA-6B and British Harrier GR7, GR9s and Tornado GR4.
The NGAD originated from Defense Advanced Research Project Agency studies initiated in 2014 to explore concepts for air superiority systems of the 2030s for the U.S. Air Force and U.S. Navy. DARPA completed its Air Dominance Initiative study in March 2014 and based on the results, the Department of Defense acquisition chief Frank Kendall launched the Aerospace Innovation Initiative (AII) in ...
The Lockheed Martin FB-22 was a proposed supersonic stealth bomber aircraft for the United States Air Force, derived from the F-22 Raptor air superiority fighter. Lockheed Martin proposed its design in the early 2000s with support from certain Air Force leaders as an interim "regional bomber" to complement the aging U.S. strategic bomber fleet, whose replacement was planned to enter service ...
