Wait a minute, Screaming Boy has a point. Beyond the ME262, the ME109 was a formidable opponent, again with variants that lasted the war. Aesthetically homely, it remained very simple to produce and highly effective. Better still was the FW 190, truly feared by the Spit pilots.
Though I can empathize with those arguing in favour of the P38 and P47 (Thunderbolt and Razorback variants), I don't agree. The P38, with exceptional range, firepower and climbing ability, was in serious trouble when it came to maneuverability. It was also the second-best look aircraft of the war. The Jug was not. In fact, the P47 was one of the most pugnacious looking planes you'll find that were not manufactured by Grumman. 500lb. bombs, rockets, .50 cal guns - the thing was armed to the teeth, but again, lacking in the ability to dogfight. Zoom-and-boom, definitely.
I give more credence to the P51. With range that allowed for fighter protection for the American daylight bombing groups for the first time, and a tremendous record, it still looks to me like a plane that was thrown together. Indeed it was, in nine months as I recall.
Really, with the exception of the P38 and some facets of the P51 and Corsair, the Americans produced some of the worst-looking aircraft of the war. Look at the P39 Airacobra. Hideous.
Still, for it's longevity, ability and appeal, the best aircraft of the was was the Spitfire.
