How could Admiral Fisher have introduced Dreadnought without weakening Britain's relative battleship advantage?
Short answerHe could not avoid obsolescence, but ordering a large first batch would preserve a daunting numerical lead.
NotesIntroducing Dreadnought inevitably changes the relative value of the pre-dreadnought fleet. The proposed way to cushion Britain's position is to order eight of the new ships immediately. That would establish an eight-to-none lead while competitors began their programs. If Germany then ordered four and Britain ordered another four, the hypothetical totals would become twelve against four. This preserves a numerical advantage in the new type without reversing the effect on older battleships.
