U.S. Northern Command

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. USNORTHCOM defends America's homeland — protecting our people, national power, and freedom of action. United States Northern Command Defends Our Homeland - Deters, detects, and defeats threats to the United States, conducts security cooperation activities with allies and partners, and supports civil authorities. USNORTHCOM’s AOR 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. USNORTHCOM consolidates under a single unified command existing missions that were previously executed by other DOD organizations. This provides unity of command, which is critical to mission accomplishment. USNORTHCOM plans, organizes and executes homeland defense and civil support missions, but has few permanently assigned forces. The command is assigned forces whenever necessary to execute missions, as ordered by the president or secretary of defense. Civil service employees and uniformed members representing all service branches work at USNORTHCOM’s headquarters located at Peterson Space Force Base in Colorado Springs, Colorado.
