Got your interest? A bit annoyed that I've just dissed the amazing quantity of production from the US? Good. I've been thinking about the book Barnes Wallis's Bombs and it mentioned that near the end of the war, when 617 Squadron were joined by 9 Squadron as tallboy bombers, the need for the bombs far outstripped the capability of the British manufacturers. Now because of this Tallboy bombs were then also produced in America and shipped over empty to this country for use. Now here's the crux of the matter. The American bombs were so roughly made that they could not be used. They would have to be taken away, all of the welding rubbed down to smooth out the casing and the fins removed and re-welded on at the correct angles in order for the bomb to spin correctly and penetrate the targets. This cost time and effort that could have seen more Tallboy's dropped on other targets. So in such a specialised area the British manufacturing where precision over quantity came to the fore far outstripped the American quantity over quality. What do you think?
