The jump from the YF-23 to the F-35 is easily explained, if a little hard to understand why.
It is simply the changing of the role identity letter of the Experimental X-35 to the fighter F-35. I don't know why the X-35 couldn't lead to the
production fighter 'F-24' but there it is.
Also ghost, your list of US fighters has too many gaps as you have missed off several aircraft, McDonnell F-3, Douglas F-10 and Grumman F-11 being
three of them. I don't know how many more you missed but those are the ones I noticed straight away.
