The F135 is a turbofan engine designed for the F-35 Lightning II, a family of stealth multirole fighters. Developed by Pratt & Whitney, it provides advanced capabilities, including thrust vectoring for enhanced maneuverability and reduced radar cross-section, contributing to the aircraft's stealth features. This engine is notable for its versatility, powering all variants of the F-35, including the conventional takeoff and landing (CTOL), short takeoff and vertical landing (STOVL), and carrier-based (CV) models. The F135 is designed for high performance, reliability, and maintainability, making it a critical component of modern air combat systems.
