Ironically, the US Air Force was dangerously close to declaring the F-14 ready for active duty in North America as an interceptor in the late 1970s. The decision to use the Tomcat was motivated as much by the doctrine of Continental Air Defense Command (ADCOM) as by any particular merits of the aircraft itself. By the time the Tomcat emerged in the mid seventies, the geometry of air defense had shifted dramatically. With the advent of Soviet long range aviation, planners found themselves confronted with threats that required not only fast response time but also range and multi target capability prior to launching stand off strikes against an American airbase. The aircraft designed specifically to meet these criteria would need radar powerful enough to lock onto 24 potential targets at once and the armament that could attack at least six of them simultaneously. In the context of this new doctrine, the F-14 was an ideal candidate.
It is difficult not to see how the Tomcat could be classified as anything else but a fleet defense interceptor an aircraft with a proven record in intercepting targets far from its base of operations. It may seem odd that the Air Force was seriously considering adding another ship based interceptor to the fleet, but the F-14 was unique in many respects. In 1972, Grumman had gone as far as designing an F-14 mock up in ADCOM livery and testing it on a runway in Calverton. What was once the main characteristic of carriers turned into an attractive quality of the aircraft range, endurance, and advanced electronics to match the performance of its weaponry.
There were, however, some issues inherent to the Tomcat. Besides the problems associated with the aircraft itself, the Navy had a rather turbulent history with its procurement process. The F-14 initially relied on TF30 engines prone to frequent compressor stalls and high maintenance costs. Both of these qualities would become a burden for a homeland defense fleet where reliability and endurance meant everything. Yet, those very characteristics had also become the strengths of the plane, contributing significantly to its value as an interceptor.
Ultimately, the Tomcat’s greatest flaw was the doctrine of continental air defense. By the mid seventies, the Air Force had stopped thinking about airbases as vulnerable sites in need of protection from fast moving bombers. They wanted something better a plane capable of destroying approaching fighters and bombers alike in the course of one flight. Thus, the Tomcat’s competitor and eventual winner the F-15 Eagle was developed.
It is interesting to note, however, that the basic concepts of the Tomcat have remained valid until this day. Indeed, multi target beyond visual range engagements and long range detection capabilities have been successfully used by modern fighter planes. The problem with swing wings lies in ever improving flight control mechanisms and materials science, but the concept itself lives on through other methods. It seems like the Tomcat’s failure was more than simply losing out to a better plane. It was the failure to recognize a paradigm shift.
