PATUXENT RIVER, Md. (June 14, 2012) Cmdr. Eric Buus pilots the F-35B Joint Strike Fighter test aircraft BF-2 as it completes the first test flight for the short takeoff and vertical landing variant with an asymmetric weapons load. The weapons load included an AIM-9X Sidewinder inert missile on the starboard pylon, a centerline 25mm gun pod, and a GBU-32 and AIM-120 in the starboard weapon bay. The F-35B is the U.S. Marine Corps variant of the Joint Strike Fighter, capable of short takeoffs and vertical landings for use on amphibious ships or expeditionary airfields to provide air power to the Marine Air-Ground Task Force.
