The General Dynamics F111 was not just any other aircraft of the Cold War. It was born as part of the Tactical Fighter Experimental program ordered by Robert McNamara himself to create a plane that could fit roles requested by both the Navy and the Air Force. The F111 had a troublesome beginning in the 60s. And at the heart of it was an old grudge between the military branches. Like many of its colleagues of the epoch, the F111 had unique innovations and cons that left the two branches divided.
