The U.S. Coast Guard is one of the five armed forces of the United States and the only military organization within the Department of Homeland Security. The Coast Guard protects the maritime economy and the environment, defends our maritime borders, and saves those in peril.
The Coast Guard is a military, multi-mission maritime service, charged with protecting the public, the environment, and U.S. economic interests in the nation’s ports and waterways, along the coast, on international waters, or in any maritime region as required to support national security.
The complexity of its missions and the size of its area of responsibility require a Coast Guard with capable people, aircraft, cutters, and boats. The service is responsible for the safety and security of America’s inland waterways, ports, and harbors; more than 95,000 miles of U.S. coastlines; U.S. territorial seas; 3.4 million square miles of ocean defining our exclusive economic zones; and international waters or other maritime regions of importance to the United States.
