Defending the Homeland
U.S. Northern Command (USNORTHCOM) was established Oct. 1, 2002 to provide command and control of Department of Defense (DOD) homeland defense efforts and to coordinate defense support of civil authorities. Our mission is to defend America's homeland — protecting our people, national power, and freedom of action.
Our area of responsibility includes air, land and sea approaches and encompasses the continental United States, Alaska, Canada, Mexico and the surrounding water out to approximately 500 nautical miles. It also includes the Gulf of Mexico, the Straits of Florida, portions of the Caribbean region to include The Bahamas, Puerto Rico, and the U.S. Virgin Islands. The commander of USNORTHCOM is responsible for theater security cooperation with Canada, Mexico, and The Bahamas.
Evolving challenges require us to maintain a sufficient, lethal combat capability to deter or defeat military attacks on the homeland. Maritime, aerospace, cyber, and weapons of mass destruction attacks comprise the most significant military threats to North America. We stand ready to deter, detect and defeat these threats to our homeland. We will not fail.
