Re: Gollevainen's quizz of the week
I would then say Northrop P-61E, wich were P-61B-10s converted to long range daytime escort fighters. A tandem cockpit wich replaced the turret. Additional fuel tanks in the rear at the former radar operators cockpit. The radar in the nose was replaced with four cal.50 machine guns.
The first prototyp of it was later converted to a XF-15.
