The Royal Air Force and Royal Navy jointly operate UK F-35Bs from RAF Marham and the Queen Elizabeth-class carriers. The F-35A is the conventional takeoff and landing variant of the Lockheed Martin F-35 Lightning II Joint Strike Fighter — single Pratt & Whitney F135 engine, internal weapons bays in clean configuration, and the AN/APG-81 AESA radar at the heart of a sensor-fusion cockpit.
