This is absurd... THe Me209 was a propoganda stunt to try to steal the world speed records of the time. There was all of 1 or 2 made. They were unarmed. They were NOT combat aircraft. On top of that it was a major blunder because the performance was WORSE than actual combat aircraft!
Please, for the luvva Pete, do a little reading before you wish for a plane that never really existed.
EDIT: I noticed after the fact you're talking about a paper-design with a prototype that was promptly cancelled.
Try again. Sorry. Do not pass GO, do not collect $200.00.
Do you have ANY idea how many 1-off prototypes never flew in the war? On ALL sides? There's more failed attempts than there were successes!
We have a precedent, as you state, but this does NOT meet the criteria.
Criteria are (in no particular order):
1) Production craft only (no test platforms or prototypes)
2) Must have served at least one unit in force
3) Must have seen combat.
