Industrial depth behind destroyer fire control

Britain could call on many competing gun, turbine, and equipment firms that also pursued export business. Their own research often gave the Admiralty a useful starting point when a new requirement appeared. The British 15-inch gun example starts with a design already tested by its maker, whereas the German response remained a paper proposal. Germany's concentrated naval market and the army's budget priority gave its navy fewer parallel suppliers to draw upon. The standard high-angle control system was too heavy for a destroyer, but one firm had already spent several years developing a lighter alternative. By 1935 that fire-control clock was part-way toward the Tribal requirement, so the Navy did not have to begin from scratch. Even under treaty limits and government-backed shipyard rationalization, enough industrial depth remained to shorten the path to usable equipment.
