Short Takeoff/Vertical Landing
F-35B Lightning II
The F-35B short takeoff/vertical landing (STOVL) variant is the world’s first supersonic STOVL stealth aircraft. It is designed to operate from austere bases and a range of air-capable ships near front-line combat zones. It can also take off and land conventionally from longer runways on major bases. The U.S. Marine Corps' F-35B aircraft reached initial operational capability (IOC) on July 31, 2015, and as of January 2017, a squadron of F-35Bs is permanently based at MCAS Iwakuni, Japan.
The F-35B STOVL operation is made possible through the Rolls-Royce patented shaft-driven LiftFan® propulsion system and an engine that can swivel 90 degrees when in short takeoff/vertical landing mode. Because of the LiftFan®, the STOVL variant has a smaller internal weapon bay and less internal fuel capacity than the F-35A. It uses the probe-and-drogue method of aerial refueling.
F-35B aircraft have been delivered to the U.S. Marines and the UK. U.S. STOVL aircraft are stationed at the first operational F-35B base, Marine Corps Air Station Yuma, Arizona, and Marine Corps Air Station Beaufort, South Carolina, where F-35B training is taking place. The first UK F-35Bs are located at RAF 17 Squadron, Edwards AFB, California, where operational testing is being conducted. The Italian Air Force will also operate the F-35B.
