Procurement cover for Dreadnought's new guns

The Royal Navy ordered only two Lord Nelsons, unusually few beside earlier classes, but that small order helped make Dreadnought's procurement less conspicuous. The same 12-inch Mark X guns and turrets were already being built and fitted for the older-style ships. Dreadnought's five twin turrets represented enough gunhouses for roughly two to three Lord Nelsons, sharpening the question of whether one all-big-gun ship justified concentrating so much armament. This allowed the Navy to test a revolutionary battleship concept while retaining a large existing force and the option to change course if results disappointed.
