<P> In the beginning of World War II the Royal Navy was still the strongest navy in the world , with the largest number of warships built and with naval bases across the globe . Totalling over 15 battleships and battlecruisers , 7 aircraft carriers , 66 cruisers , 164 destroyers and 66 submarines . In the course of the war the United States Navy grew tremendously as the United States was faced with a two - front war on the seas . By the end of World War II the U.S Navy was larger than any other navy in the world . </P>
