US Merchant Marine

The United States Merchant Marine is a civilian auxiliary of the U.S. Navy, composed of civilian-owned merchant ships and their crews that transport goods and materials during peacetime and serve as a vital logistical force in wartime. Its origins date back to the American Revolution, when merchant vessels supported the Continental Navy. During World War II, the Merchant Marine played a crucial role, suffering high casualty rates while delivering troops, equipment, and supplies to every theater of war. Today, the Merchant Marine continues to support military operations and national emergencies, maintaining a fleet ready to serve U.S. interests around the globe.
