Según KeyAero.com, el prototipo BF-01 del F-35B, ha comenzado las pruebas de aterrizaje y despegue vertical(STOVL).
El vuelo tuvo lugar en la base naval de Patuxent River,Maryland,(USA). El sistema STOVL fue utilizado durante 14 minutos a unos 180-210 nudos, antes de volver al modo de vuelo convencional. La velocidad se irá reduciendo progresivamente, hasta llegar al aterrizaje y despegue vertical. El prototipo BF-01 está propulsado por Pratt & Whitney F135 con una potencia de 41,000 libras de potencia vertical.

According Lockheed Martin’s F-35B Lightning II short takeoff and vertical landing (STOVL) test aircraft BF-01 engaged its STOVL propulsion system in flight for the first time.
The flight took overNaval Air Station Patuxent River in Maryland, USA. During the flight, the STOVL propulsion system was engaged for 14 minutes between 180-210 knots before converting back to conventional-flight mode.
Further STOVL test flights will see the aircraft fly progressively slower before hovering and ultimately landing vertically. BF-01 is powered by the Pratt & Whitney F135 engine driving the Rolls-Royce LiftFan® system, which produces 41,000 pounds of vertical thrust.
