During WW2, the Supermarine factory at Southampton was overwhelmed by orders, and also suffered severe bombing, so Spitfires were also built at several other places, Westland Aircraft, Nuffield car factories, and in Vickers, Castle Bromwich. - It's difficult to track all the numbers, but almost 55% of all Spitfires were built in Castle Bromwich. In one period, June 1942 -July 1943, Castle Bromwich made over 2,190 Spitfires, mostly MkV and IX. - That's almost 6 aircraft per day - amazing !
