Best Fighter Designer?

[Soren]

The best fighter designer of WWII is definitely Kurt Tank.

As a second I'll go with Willi Messerschmidt.

And as a third T. Koyama for his near unbeatable design when it comes to low alt speed and maneuverability, the Ki-84 "Hayate" or "FRANK" as the Allies called it.

I pretty much am the same as your list except that I would throw in Kelly Johnson in third. Sure most of his best designs came after the war but he made some magnificant designs as well during such as the P-38, Constellation and Electra.

Another good designer or team of designers was Boeing's and Curtis's and even Douglas's.

Kelly made some beautiful designs alright, but I cannot help but admirer T.Koyama for churning out such a fantastic design considering the conditions in which the Japanese industry had to work under by 43-45. Yet he pulled it off and made a fighter considered untouchable at low altitude by even the very latest Allied fighters.

He did do some great things with that design.

Indeed he did.

Capable of approx. 620 + km/h at sea level using MW boost this was one very fast bird at low altitude. Service ceiling was 40,000 + ft.
