![]() If one observes carefully, it can be concluded that there are many similarities between the F-111 and the F-14, not only the geometrically variable wings. As Grumman was awarded with the contract in 1968, it incorporated two features of the unsuccessful F-111B project: the two Pratt & Whitney TF-30-P3 engines and the required AWG-9 radar for the AIM-54 Phoenix. Its design is based in the aforementioned requirements, which required the new fighter to carry a combination of AIM-9 Sidewinder short-range missiles, AIM-7 Sparrow medium-range missiles, and long-range AIM-54 Phoenix missiles, alongside the 20mm M61A1 Vulcan cannon. This results in a wide space between the two nacelles giving the Tomcat it’s characteristic shape. The flat area between the engines nacelles, at the rear of the fighter, purposed to contain fuel and avionics components, such as the controllers for the wing-sweep mechanism, flares and chaff and other flight assist functions. The control of the wing movement was automatic with manual control if needed. ![]() When swept outwards, the wings naturally increased drag, allowing lower speed flight and a lower stall speed. When the wings were positioned rearwards, it was fitted for high-speed intercept missions. The glove-mounted swept wings have variable geometry capability, in the same manner as the General Dynamics F-111, the Mig-23 Flogger, and the Panavia Tornado. The F-14 Tomcat is a double-seat tandem, twin-engine, double-tail, all-weather carrier-based fighter and interceptor and later gaining multi-role capability, with numerous remarkable features. Characteristics F-14B Tomcat aircraft from VF-101 circa 2004 But it also played a role in the overall design of the fighter, working very closely with Grumman providing the company with technical assistance and data. NASA also had an important role during the development stage as it did with the F-15 through the Langley Research Centre, mainly related to the F-14’s most advanced feature: the geometrically variable wings. A feat achieved by the Tomcat was that it had its first flight 23 months after the contract was awarded, making the of the Tomcat a milestone in the development of new air assets. It was also directed to have a secondary Close Air Support (CAS) role and incorporate an internal M61A1 20mm Vulcan cannon, correcting the mistake made with the previous Phantom F-4, as it had no internal gun for close-range combat. The Naval Air Systems Command (NAVAIR) also had a role, as it issued requirements for a tandem two-seat, twin-engine fighter with mainly air-to-air capacities capable of reaching speed of up to 2.2 match and able to operate with a new generation missiles. ![]() The F-111B proved unsuitable for the conditions of the Vietnam War and had no long-range missile capability. Second, the ongoing TFX F-111B project was facing a large number of issues in the late 60s that made both the Navy and Grumman, which happened to be the builder of the F-111B alongside General Dynamics, to consider a new option with better capabilities and less operational and development issues. But the Navy stepped out in fears that the USAF’s need for a low-attack aircraft would hamper the fighter abilities of the new airplane. The role of then Secretary of Defence Robert McNamara was also crucial in this case, as he directed the Navy to take part in the Tactical Fighter Experimental program. It also needed a more capable radar and provision for longer range missiles. First, the Navy’s quest to find a Fleet Air Defence asset, with long-range and high-endurance interceptor characteristics to defend the aircraft carrier battle groups, mainly against long-range anti-ship missiles launched from Soviet bombers and submarines, in addition to intercepting those same Soviet bombers. It has a similar origin to that of the F-15, but it is also the result of two additional factors. It is also a replacement for the F-4 Phantom and the failed F-111B, incorporating the lessons and experiences acquired during Vietnam as well, like the F-15 Eagle. The F-14 Tomcat is the most iconic Cold War US Naval fighter, next to the McDonnel Douglas F-4 Phantom.
