The F3H Demon was McDonnells first swept-wing turbojet fighter design.

The F3H Demon series of aircraft produced by McDonnell Aircraft was a further development of the company's expertise with carrier-based turbojet-powered aircraft. Ever since the arrival of the Japanese "Zero" to the war front in World War Two, there was great belief by such aircraft firms that carrier-based craft could easily match or even supercede the performance offered up by their land-based counterparts.

Nearly a decade later since the end of the conflict, McDonnell was hard at work in trying to match their earlier carrier-based attempts in the F1H and F2H series of aircraft. The F3H Demon was such an attempt, becoming the company's first attempt at a swept-wing turbojet fighter - a technology incidentally pioneered by German engineers in the Second World War.

The Demon featured folding wingtip assemblies for added storage space on American carriers and was a single seat, single engine aircraft. Twin intakes were fitted on either side of the forward-mounted cockpit and the single exhaust was uniquely fitted under the tail assembly - which in itself featured low-mounted elevators. The wing systems were of a low-monoplane variety and the aircraft housed a more modern-looking tricycle powered land gear design.

The F3H Demon was designed from the outset to become the first aircraft in the world to be built specifically with air-to-air missile technology capability in mind. It would not be until the more definitive F3H-2 model that the system would be fitted with the 4 x 20mm cannon armament consistent wit earlier McDonnell turbojet designs. The system would be fielded with a standard array of 4 x Aim-7 Sparrow medium-range air-to-air missiles.

Production delays and an underpowered initial powerplant led to the F3H seeing considerable development time. Since the initial flight in 1951, the system would not be fielded up until 1956. The F3H Demon would go on to miss the Korean War altogether, though - after powerplant issues were dealt with - the United States Navy would field no fewer than 10 squadrons with the new and nimble missile-threatening F3H Demons.
