The United States Merchant Marine is an organization composed of United States civilian mariners and U.S. civilian and federally owned merchant vessels. Both the civilian mariners and the merchant vessels are managed by a combination of the government and private sectors, and engage in commerce or transportation of goods and services in and out of the navigable waters of the United States. The Merchant Marine primarily transports domestic and international cargo and passengers during peacetime, and operate and maintain deep-sea merchant ships, tugboats, towboats, ferries, dredges, excursion vessels, charter boats and other waterborne craft on the oceans, the Great Lakes, rivers, canals, harbors, and other waterways. In times of war, the Merchant Marine can be an auxiliary to the United States Navy, and can be called upon to deliver military personnel and materiel for the military.

World War II United States Merchant Navy was the largest civilian Navy in the world, which operated during World War II. With the United States fighting a world war in all the world oceans, the demand for cargo and fuel was very high. Cargo and fuel was needed around the world for the United States Navy, United States Army, United States Marine Corps, United States Army Air Forces, United States Coast Guard and the support of the allied nations of the United States. American steamship companies chartered ships from the Maritime Commission and War Shipping Administration to meet the demand. Many United States Merchant Marine ships were newly built in the Emergency Shipbuilding Program, other ships were older World War I ships that were put back in service, or private ships acquired under Emergency war requisitions. The Merchant Navy operated in the Pacific War and European war. Over 200 US Merchant ships took part in the D-day Normandy landings. To make a Normandy breakwater Harbor, called Mulberry harbour, 33 merchant ships were sunk 1,000 yards from shore. Some of the ghosts merchant ships used were damaged and others were deemed too old.
