Dear Friends, thanks a lot for the comments.
I'm not an engineer so it was not clear for me that this could be the tipycal shape for a Mach 2 interceptor: rounded nose and no area ruled fuselage...but Northrop's Fang had a similar nose and was a Mach 2 performer.
Please let me show a little comment:
I seem to remember that (F-105) was a Mach 2 aircraft
I thought the same of you, Evan and Paul, but according to "The American Fighter" by Angelucci & Bowers the Thud's max speed at 33,000 ft was 857 mph (1,379 Km/h) which it's below 1.5 Mach.
And the last question: what are this "things" in the wing tips of AP-54?. Too slim to be a fuel tank....
