What does P mean in aircraft?
For example, before the new system, the Army Air Force used the “P” designation, which stood for pursuit, on a wide variety of its fighter aircraft, like the P-51 Mustang, P-47 Thunderbolt and P-38 Lightning. The Navy, though, used the “F” designation for its fighter aircraft.
