A piece of artwork from North American illustrating a vertical takeoff and landing aircraft. This was clearly intended for high speed… not only does it have four turbojet engines for forward thrust, if also have variable sweep wings. The complexity here is that the wings have embedded lift fans, probably driven be high pressure exhaust gas from two or more of the main turbojets. The ductwork would be impressive.
Role is unclear, but it appears to be a fighter or strike-fighter. Indications of weapons bays on the fuselage underside; at least one forward-firing gun. No other data available.
