At the end of World War II, the U.S. Navy was supreme on the world’s oceans. The United States had come out of the war with the largest, most technologically advanced and sophisticated fleet in the world. In addition, aircraft carriers and amphibious forces gave us the ability to project power ashore. Our submarine and surface forces had proved themselves capable of protecting the sea lanes linking the United States with its allies while denying those lanes to the enemy. No opposing navy threatened this fleet.
