The Coast Guard
& Homeland Security


The United States Coast Guard's homeland security mission is not new to us.  It is more visible today than it was prior to the tragic events of September 11, 2001, but it is just as important as it was when we first began protecting our national sovereignty 211 years ago.  The Coast Guard maintains a clear vision and a keen sense of vigilance while keeping watch for threats to our security and those who would do us harm.

As part of Operation Noble Eagle, the Coast Guard is at a heightened state of alert protecting more than 361 ports and 95,000 miles of coastline, America’s longest border.  The Coast Guard continues to play an integral role in maintaining the operations of our ports and waterways by providing a secure environment in which mariners and the American people can safely go about the business of living and working freely.

In the wake of the September 11 terrorist attacks, the Coast Guard immediately mobilized more than 2,000 Reservists in the largest homeland defense and port security operation since World War II.  The Coast Guard has increased its vigilance, readiness, and patrols to protect the country’s 95,000 miles of coastline, including the Great Lakes and inland waterways.

The Coast Guard's homeland security role includes:

Operation Noble Eagle refers to U.S. military operations associated with homeland defense and civil support to federal, state and local agencies in the United States, and includes the increased security measures taken after the September 11 terrorist attacks.  The operation involves joint agency coordination and cooperation to ensure our nation and borders are protected from future attacks.  An increased presence will prevent and deter those who would cause harm to innocent Americans.

Operation Enduring Freedom refers generally to U.S. military operations associated with the war on terrorism outside the United States.  Coast Guard port security units have deployed in support of this operation.
