The Grumman F-14B Tomcat prototype (BuNo 157986) in flight.

During the development of the F-14, Grumman intended to have better engines but as a temporary solution the TF30 engine was used as with, with intent to replace when the program went to the fleet. Therefore, on 27 February 1970, Grumman suggested a Tomcat variant powered by the winner of the "Advanced Technology Engine". This variant was designated F-14B.[1] The winner of the engine contest became the Pratt & Whitney F401-P-400. The seventh F-14A (BuNo 157986) served as the prototype and first flew on 12 September 1973. It first with one F401-P-400 engine and one TF30 engine, later, the aircraft was equipped with two F401 engines. Original plans called for the F-14B to start rolling off the production line with the 67th F-14, with earlier F-14As being converted to F-14B configuration. However, the development of the F401 turbofan soon ran into serious problems. Since the F-14A had already encountered severe cost overruns, and since the budget had been severely cut back at the end of the Vietnam War, the U.S. Navy decided to cancel further development of the F-14B in April 1974. 157986 accumulated only 33 hours of flying time and was put into storage. In 1981, it was reactivated for the evaluation of the General Electric F101 DFE (Derivative Fighter Engine) turbofans engine used in the F-14A+. The F-14A+ also received the ALR-67 Radar Homing and Warning (RHAW) system but much of the avionics as well as the AWG-9 radar were retained. The F-14A+ was later redesignated F-14B on 1 May 1991. A total of 38 new aircraft were manufactured and 48 F-14As were upgraded into B variants. 157986 is today on display at the Intrepid Sea-Air-Space Museum, New York (USA).
