Flashback: Convair’s F-102 and F-106 – Aren’t they really the same airplane?
In the early days of jet fighters, the U.S. Air Force acquired both the F-102 and F-106, two different aircraft that look remarkably similar. But a closer look, particularly at the fuselage shapes, reveals a subtle yet significantly important difference.
Performance wise, that difference in shape allowed the F-106 to be a more successful design and more effective and suitable for USAF missions. The design principle that distinguished the F-106 was the application of a theory called “Whitcomb’s Area Rule”, named after Richard Whitcomb, an engineer with the National Advisory Committee for Aeronautics (NACA) – the forerunner of the National Aeronautics and Space Administration (NASA.)
Whitcomb’s aerodynamics research allowed a generation of jet aircraft to more easily exceed the speed of sound and deliver to the Air Force the performance it was after to intercept Soviet bombers.
