How much cheaper would capital ships become if Germany ordered classes of eight or ten before the First World War?
Short answerNot necessarily cheaper; Germany would overload its yards, stagger delivery, and risk receiving obsolete ships while Britain matched the order more quickly.
NotesOrdering a larger class can spread design and production costs, but the saving depends on industrial capacity. Germany could not lay down eight or ten capital ships simultaneously, so a nominal batch would be staggered across years. Late ships might enter service behind newer British designs, while Britain could answer the order with its larger yard base. The most efficient policy is to order slightly below sustainable capacity while merchant and foreign work keep the industrial system alive. Ordering too little wastes capacity, but ordering far too much raises cost and delay instead of producing simple economies of scale.
