This thing kinda looks like a F-87.
FYI: The XA-43 was redesignated XF-87.
Yes, but not quite. By redesignating them, the USAF also signified a slight change of mission. From mainly "attack", these aircraft became mainly "fighters": XA-42 became XB-42 (no big deal, it remained purely experimental, anyway); XA-43 became XP-87, XA-44 became XB-53 and the Martin XA-45 became XB-51. But you need to remember that on each occasion (except for the B-42) the design was also altered along the way.
