F-35B aircraft in formation
F-35 test pilots Marine Corps Maj. C. R. Clift and Navy Lt. Cmdr. Michael Burks fly BF-2 and BF-4 during a formation flying qualities test in the Atlantic Test Range Aug. 22. Testing formation flying qualities provides data on handling characteristics. The F-35B is the variant of the Joint Strike Fighter designed for use by U.S. Marine Corps, as well as F-35 international partners in the United Kingdom and Italy. The F-35B is capable of short take-offs and vertical landings to enable air power projection from amphibious ships, ski-jump aircraft carriers and expeditionary airfields. The F-35B is undergoing test and evaluation at NAS Patuxent River, Md., prior to delivery to the fleet.
