The U.S. Navy was started in an era when the true measure of a country was the size and strength of its naval forces. A strong fleet of ships could mean the difference between losing and winning a war. The Revolutionary War was just getting started, and the matter of a navy began to become more pressing as imminent battle drew near. Some argued that it would be impossible to challenge the British navy, since they had the most powerful of the time. However, in a move to protect shipments and defend the new country, Congress began to build a fleet.
