Navy test pilot Lt. Christopher Tabert flies F-35B aircraft BF-3 with inert AIM-9X Sidewinder missiles Sept. 19 over the Atlantic Test Ranges. The test flight evaluated airplane structural loads and flying qualities during maneuvering flight. 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.
