The Tomcat Arrives The Grumman Corporation learned from the mistakes it made while developing the F-111B. Grumman paid attention to these lessons when it designed a much lighter, cheaper and far better performing aircraft -- the F-14. On February 3, 1969, Grumman was awarded a contract to build twelve F-14A fighters and the company began production immediately. Grumman was already familiar with swing-wing fighters, having created the XF10F-1 Jaguar, whose wings could sweep through 40 degrees. In an incredible manufacturing feat made possible by the experience on the TFX, the F-14A made its first flight on December 21, 1970, after only twenty-one months from "go ahead." But the career of this first prototype ended quickly. On its second flight, a hydraulics failure sent the aircraft out of control and forced the pilots to eject. The remainder of the test program, however, went well and the F-14A entered operational use in October of 1973. The F-14 was an instant success, popular with pilots because of the maneuverability created by the swing wing. The handling of the Tomcat took center stage in the 1986 film "Top Gun." Mechanics also liked the Tomcat because despite its complexity, it was not hard to maintain. The F-14 also provides a good example of the difficulty in crossbreeding Navy and Air Force aircraft. It was unable to beat the F-15 in a competition to meet an Air Force interceptor requirement, while a shipboard version of the F-15 was deemed too heavy and expensive for Navy use.
