PATUXENT RIVER, Md. --- An F-35B Lightning II completed the first ramp-assisted short take off to test the aircraft’s compatibility with British and Italian aircraft carriers.

“This test was a success for the joint ski jump team," said Peter Wilson, BAE Systems F-35 test pilot and U.K. citizen, who flew the June 19 mission at Naval Air Station Patuxent River, Maryland. "The aircraft performed well and I can't wait until we're conducting F-35 ski jumps from the deck of the Queen Elizabeth carrier.”

Two F-35 partner nations use ramp-assisted short take offs for their carrier operations as an alternative to the catapults and arresting gear used aboard longer U.S. aircraft carriers. The shorter U.K. and Italian carriers feature an upward-sloped ramp at the bow of the ship. Curved at its leading edge, a ski-jump ramp simultaneously launches aircraft upward and forward, allowing aircraft to take off with more weight and less end-speed than required for an unassisted horizontal launch aboard U.S. aircraft carriers.

The F-35B's design allows it to automatically position the control surfaces and nozzles for takeoff - a unique capability compared with previous short takeoff and vertical landing aircraft. Such automation frees up pilot capacity and provides an added safety enhancement.

"The control laws on the F-35B are designed to make the task of taking off and landing at the ship much easier than for previous STOVL aircraft,” said Gordon Stewart, flying qualities engineer representing the UK Ministry of Defence. “For ski jump launches, the aircraft recognizes when it is on the ramp and responds by positioning the control surfaces and nozzles automatically for takeoff and climb. This was our first chance to demonstrate these new control laws using a land-based ski jump. We'll be using these results — along with those from future testing — to help us prepare for the first shipboard ski jump launch from HMS Queen Elizabeth.

First Ski Jump for F-35B Lightning II

The F-35B Lightning II has successfully completed its first ski jump test at Naval Air Station Patuxent River in the US state of Maryland.

The ramp used was built in England however, at a cost of £2 million, by Stockport-based defence engineering company WFEL - who normally specialise in building rapidly deployable bridging systems.

The development complements the sea trials the Joint Strike Fighter has been undergoing with the US Marine Corps, the Royal Navy and the Royal Air Force onboard USS Wasp.

This latest combat aircraft, with an in-service date of December 2018 for the UK, will put the British Armed Forces at the forefront of fighter technology.

When they start flying from the new Queen Elizabeth Carriers in 2020 it will restore the Fleet Air Arm's ability to conduct fixed-wing, front-line operations.

That was lost in 2010 with the controversial retirement of the Harrier GR9's.

The MoD has so far ordered 48 F-35B's with four delivered and already undergoing testing.

Among those tests is the dropping of UK armament's including the Paveway IV laser-guided bomb.
