That's the North American NA-431, one of three "Type A" proposals for the U.S. Navy (the other two being NA-420 and NA-430, see attachments).

I don't think so. Despite some commonalities, there are also some notable differences:
  • Small canopy on NA-420, large canopy and small nose on this design
  • Engine pods below wing on NA-420, but partly above on this design
  • Tail unit seems to extend further aft on this design
BUT... it could still be a different sub-variant of the NA-420.
