F-35 Lightning II — 4 museum-grade prints, engineered to a wall. The F-35B is the short take-off and vertical landing variant of the Lockheed Martin F-35 Lightning II — Rolls-Royce lift fan, swivelling rear nozzle, and the same sensor-fusion cockpit that defines fifth-generation employment. The Royal Air Force and Royal Navy jointly operate UK F-35Bs from RAF Marham and the Queen Elizabeth-class carriers. The F-35 Lightning II program became the most expensive weapons development effort in history while simultaneously delivering the first mass-produced stealth fighter available to allied air forces beyond the United States. The F-35A's sensor fusion architecture — combining radar, electro-optical targeting, and distributed aperture feeds into a single pilot picture — redefined how fourth- and fifth-generation aircraft cooperate in contested airspace. 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. Hill AFB's 388th Fighter Wing became the USAF's first operational F-35A wing, with the 34th Fighter Squadron — the Rude Rams — among the lead units flying the type from northern Utah.
