Why the F-35 Was Designed With a Single Engine
Lockheed Martin's F-35 Joint Strike Fighter uses one engine across all variants, a choice tied to the programme's goal of sharing parts, systems, weight and cost.
Lockheed Martin designed the F-35 with one engine, not two. Three US military branches fly the aircraft, and every version uses the same single-engine layout.
For a conventional fighter, that choice looks simple. The F-35B has to move between conventional flight and short takeoff and vertical landing, which makes one engine seem counterintuitive.
Engine count was never just a propulsion decision. It was tied to how the Joint Strike Fighter programme was meant to share parts, systems, weight and cost across its variants.
