Oddly enough, French tank development during WWII stopped in 1940, thus leaving the French without any tanks that would match up to the tanks in AH. We need French fighters before we need French tanks anyways.
You trying to say French fighters would be a match up to the fighters we have in AH? Maybe the D.520 since the Luftwaffe thought it was such a good aircraft they continued production after the armistice with France was signed.
