The Lockheed Martin F-35B Lightning II – the first production-representative Joint Strike Fighter (JSF) short take off and vertical landing (STVOL) strike aircraft – made its maiden flight on 11 June 2008 piloted by British Aerospace Systems (BAE) test pilot Graham Tomlinson at the company’s Fort Worth facility. Developed to be the world’s premier strike aircraft through to 2040, three versions are under development: the F-35A a conventional takeoff and landing variant, which has already flown; the F-35B, short-takeoff and vertical-landing variant; and the F-35C, carrier-based variant.
