Several German capital ships historically relied on Parsons turbines procured from Britain because early domestic machinery was less reliable and efficient. A larger Royal Navy program could absorb British turbine output and quietly deny Germany access to those engines. Germany might answer with domestic turbines, diesel machinery, or continued triple-expansion engines, but each route carries delay or performance risk. Machinery shortages and immature replacements could erase roughly a dozen apparent additions from the German building program.

British turbine leverage slows German construction
Germany's dependence on British Parsons turbines creates a supply-chain vulnerability that new hull orders cannot solve quickly.
