F35 JSF Take Off

F-35A Flight with External Stores

On Feb. 16, 2012, the first external weapons test mission was flown by an F-35A conventional takeoff and landing (CTOL) aircraft at Edwards Air Force Base, Calif. The F-35A is designed to carry up to 18000 pounds on 10 weapon stations featuring four weapon stations inside two weapon bays, for maximum stealth capability, and an additional three weapon stations on each wing.

Lt. Cmdr. Eric 'Magic' Buus flew the F-35C for two hours, checking instruments that will measure structural loads on the airframe during flight maneuvers. The F-35C is distinct from the F-35A and F-35B variants with larger wing surfaces and reinforced landing gear for greater control when operating in the demanding carrier take-off and landing environment.
