Boeing and Lockheed Martin take different paths in vertical lift systems for fighter jets

Boeing's X-32 and Lockheed Martin's X-35 were both designed for the Joint Strike Fighter competition, but they used different approaches for vertical lift. The X-32 relied on an updated Harrier design, while the X-35 featured a new, advanced system. The X-32's design focused on simplicity and used a single-engine cycle for both conventional and vertical flight. In contrast, the X-35's innovative LiftFan technology allowed for superior performance, enabling it to conduct vertical take-offs and landings effectively. Lockheed's X-35 outperformed Boeing's X-32 in STOVL capabilities. The X-32 struggled with performance in thinner air, while the X-35 successfully demonstrated vertical take-off and supersonic flight at higher altitudes.
