Mach 1.6 is roughly 1,200 miles per hour. It can sustain flight speeds well over Mach 1 without using afterburners, which is critical in order to keep its heat signature, which aids overall stealth profile. The F-35 Lightning II max speed is a little lower, about Mach 1.6. The key to this speed which was noted earlier, is the F-22s capability to supercruise. The F-22 max speed sits around Mach 2, or over 1,500 miles per hour. Speed is definitely the focus of the F-22 Raptor, but both aircraft have impressive top speeds. If Lockheed Martin delivers 300 F-35s (it’s already delivered over 150) to the U.S., then each plane will have a lifecycle costs of about $373 million each. The F-35 unit cost is $91 million (F-35A), not including research and development or lifecycle maintenance costs. The F-35 program’s purpose is to fill the air-to-ground roles the F-22 can not, and be cheaper and more plentiful. Military wanted a cheaper, easier, potentially longer lasting option to complement what the F-22 was designed for. The rising price tag of the F-22 helped bring the F-35 into existence. The Air Force is vigorously pursuing new avionics, radar, targeting sensors, weapons, glass cockpit displays and Artificial Intelligence for its F-22 stealth fighter to try to sustain air supremacy amid Russian and Chinese 5th-generation stealth fighter technical modernization, service officials said. The Pratt and Whitney F135 engine operates in the 45,000-pound thrust class. Therefore, the maneuverability and supercruise capability aren’t as important as safety, ease of production, and continued maintenance costs. Military than F-22s when it’s all said and done. Also, many more F-35s will be built for the U.S. The F-35 Lightning II complements the F-22 by fulfilling an air-ro-ground role. One F119 engine operates in the 35,000-pound thrust class, together they operate in the 65,00-pound – 70,000-pound thrust class.Įither a F135-PW-100, F135-PW-400, F135-PW-600 power the F-35, depending on variant. Secondly, the convergent/divergent thrust vectoring nozzle, which vectors thrust up or down a maximum of 20 degrees, gives it maneuverability that the F-35 just can’t match. The Pratt & Whitney F119s gives the F-22 to ability to supercruise (operate at supersonic speeds without using afterburners). Two things set the F-22 engines apart from the F-35 engine. Two F119-PW-100 turbofan engines power the F-22 Raptor. The most obvious difference between the two aircraft is the F-22 employs two engines and the F-35 only uses one. Here is a list of areas where the F-22 and the F-35 differ. They are alike in so many different ways, but what makes them special is what sets them apart. Air Force and its contractors are the F-22 Raptor and the F-35 Lightning II. The latest and greatest products of the U.S.
