F-35 Pax River ITF Expands Expeditionary Envelope For USMC

NAVAIR News // January 22, 2018

The F-35 Patuxent River Integrated Test Force team brings the U.S. Marine Corps’ F-35B one step closer to initial operational test and evaluation as they wrap up testing of the F-35B STOVL envelope with sloped surface vertical landing tests January and February at Marine Corps Auxiliary Landing Field (MCALF) Bogue, N.C.

“The Marine Corps is an expeditionary force capable of deploying on short notice to crises around the world—even to the most austere environments, and the F-35 has an exceptional expeditionary capability.” said Maj. Michael Lippert, F-35 Pax River ITF test pilot and detachment officer-in-charge. “Conducting the testing at Bogue Field provides the Marine Corps with a unique opportunity to continue the test and development of the F-35 in the [short takeoff/vertical landing] mode, while simultaneously exercising components of the [Marine Air-Ground Task Force’s] Air Combat Element, specifically the Marine Wing Support Squadrons at Bogue and MCAS Cherry Point.”

The capability inherent in a STOVL jet allows the Marine Corps to operate in harsh conditions and from remote locations where few airfields are available for conventional aircraft—from abandoned or primitive runways, to long stretches of roadways. The aircraft can also operate from sites where Marines construct their own expeditionary runway or landing pads with AM-2 matting, similar to that used during the sloped surface testing.

Through a series of vertical landing maneuvers in simulated expeditionary conditions, the team’s end goal will ease current sloped surface vertical landing requirements for the F-35B.

“We hope to be able to relax the landing pad certification limits in terms of maximum slope/gradients in the context of expeditionary pads—existing and future,” said Bob Nantz, F-35 Pax River ITF Performance/Environmental Technical Specialist.

With Marines from the 2nd Marine Aircraft Wing capturing real-time lessons learned, some of the test results will be instantaneous. However much of the data will require significant analysis before any updates can be made to the fleet, Lippert said.

The Pax River ITF will analyze nearly 200 data test points to assess how well the F-35B operates on varying slopes, impacts of head and tailwinds, and the effect of aft center of gravity in conjunction with ground slopes.

“These updates will eventually make it to our fleet aircraft while the capabilities of the F-35 will continue to transform the way we fight and win,” Lippert said.
