JSF F-35B

Description

The Joint Strike Fighter, the JSF, is being developed by Lockheed Martin Aeronautics Company for the US Air Force, Navy and Marine Corps and the UK Royal Navy. The stealthy, supersonic multi-role fighter is to be designated the F-35. The JSF is being built in three variants: a conventional take-off and landing aircraft (CTOL) for the US Air Force; a carrier based variant (CV) for the US Navy; and a short take-off and vertical landing (STOVL) aircraft for the US Marine Corps and the Royal Navy. A 70 û 90% commonality is required for all variants. The Marine variant of JSF is very similar to the Air Force variant, but with a slightly shorter range because some of the space used for fuel is used for the lift fan of the STOVL propulsion system. The main differences between the naval variant and the other versions of JSF are associated with the carrier operations. The internal structure of the naval version is very strong to withstand the high loading of catapult assisted launches and tailhook arrested landings. The aircraft has larger wing and tail control surfaces for low speed approaches for carrier landing. Larger leading edge flaps and foldable wingtip sections provide a larger wing area, which provides an increased range and payload capacity.
