The US Navy considered developing the F-15N Sea Eagle as a faster, lighter, and cheaper alternative to the F-14. But modifying the F-15 with folding wings and stronger landing gear for carriers negated its advantages.
Often considered the most famous US Navy fighter due to its prominent appearance in Top Gun, the F-14 Tomcat served as an advanced interceptor and air superiority fighter, with the ability to engage six enemy aircraft at the same time from over 100 miles away using the AIM-54 Phoenix missile.
Improvements in Soviet long-range patrol and bomber aircraft during the Cold War created a need for a fleet defense fighter capable of engaging high-altitude bombers from a significant distance. The F-14 Tomcat, designed by Grumman, was the solution. To meet the demand for an interceptor that could achieve high speeds while carrying heavy armaments, Grumman developed the effective variable-sweep wing design of the F-14, allowing it to function efficiently across a broad spectrum of airspeeds.
The Navy’s quest for an advanced carrier-based air superiority fighter resulted in the evaluation of General Dynamics’ F-111B. This aircraft aimed to support the Department of Defense’s goal of commonality with the Air Force and its F-111A. However, the F-111B, modified to fulfill Navy mission requirements, was considered too heavy for carrier operations, leading to the cancellation of the contract in April 1968. Following this, the Navy launched a new design competition known as the VFX program, with McDonnell Douglas and Grumman as the two main contenders.
Grumman’s Model 303 suggested a twin-engined, two-seat design with variable geometry, centered on the Hughes AWG-9 weapons system.
McDonnell Douglas proposed a “navalized” variant of its latest F-15 Eagle air superiority fighter. Modifications for the F-15N included a wing hinge, a suitable arresting hook, and reinforced landing gear. According to DriveTribe, despite the extra weight from these changes, the F-15N was projected to still surpass the F-14 in maneuverability. However, the original proposal did not indicate the inclusion of the AIM-54 Phoenix missiles or the AN/AWG-9 radar necessary for targeting and launching them. A report from the US Navy assessed the addition of the radar and AIM-54s, but this would have resulted in the aircraft being 10,000lbs heavier than a standard F-15A, rejecting any potential advantage the Sea Eagle might have had. McDonnell Douglas and Hughes Aircraft, manufacturers of the AIM-54 and the radar, suggested modifying the F-15’s AN/APG-63 radar to be compatible with the AIM-54.
A Senate subcommittee began to study the proposal in 1973 and was later expanded to include a stripped F-14 variant and an upgraded F-4. A fly-off between the F-14A and F-15N was brought up but was never held.
The Navy ultimately stuck with the F-14, which proved to be an extremely capable aircraft. Following Grumman’s tradition of naming its aircraft after cats, the new “Tomcat” made its first flight in December 1970. After several changes following flight testing, the first F-14As were delivered to the Navy in June 1972, with Fighter Squadron (VF) 124 designated to provide crew training. On the West Coast, VF-1 and VF-2 were the first operational squadrons to receive the new aircraft, while on the East Coast, VF-14 and VF-32 became the first Atlantic fleet Tomcat squadrons.
