The FW190’s biggest problem was high attitude performance.
Reminds me of the screwed up deployment of the P38, politics neutered it, prototype crashes for a political show, then they make terrible decisions of its supercharger and engines for the European theater, it finally emerged in the Pacific triumphantly but if it had been put to use in Europe well before the P51 it could have saved hundreds of bomber pilots.
Stupid politicians thinking of being Generals for votes and campaign donations.
Like the Warthog, an obvious effective weapon, we need ten thousand of them built to go after ISIS.
