NAVAL AIR SYSTEMS COMMAND, PATUXENT RIVER, Md. – F-35 test pilots Navy Lt. Cmdr. Michael Burks and Peter Kosogorin of BAE fly CF-1 and CF-2 during a formation flying qualities test Sept. 5 in the Atlantic Test Ranges. Testing formation flying qualities provides data on handling characteristics. The F-35C carrier variant of the Joint Strike Fighter is distinct from the F-35A and F-35B variants with its larger wing surfaces and reinforced landing gear to withstand catapult launches and deck landing impacts associated with the demanding aircraft carrier environment. The F-35C is undergoing test and evaluation at NAS Patuxent River prior to delivery to the fleet.
