Pratt & Whitney’s engines power a wide range of military aircraft in operation around the world, but 2011’s developments in the Joint Strike Fighter (JSF) Lightning II program made the company’s year–especially as its F135 became the sole powerplant for all three Lockheed Martin JSF variants: the conventional F-35A, STOVL F-35B and carrier-based (CV) F-35C.
