Overview of U.S. Northern Command
U.S. Northern Command (NORTHCOM) is the unified combatant command responsible for protecting the United States homeland. Established on October 1, 2002, in response to the September 11, 2001 terrorist attacks, NORTHCOM represents the first combatant command specifically dedicated to defending North America.
Headquartered at Peterson Space Force Base in Colorado Springs, Colorado, NORTHCOM coordinates with federal, state, and local agencies to deter, prevent, and defeat threats to the United States. The command also provides defense support to civil authorities during national emergencies.
The NORTHCOM Commander holds a dual-hatted role as Commander of the North American Aerospace Defense Command (NORAD), the binational U.S.-Canadian command responsible for aerospace warning and control.

Homeland Defense Mission
NORTHCOM's primary mission is homeland defense, which encompasses defending the United States from attacks by hostile nations, terrorist organizations, and other threats. This includes air defense, maritime defense, and land-based defense of U.S. territory.
The command maintains continuous situational awareness of the North American approaches, monitoring for potential threats from aircraft, missiles, maritime vessels, and ground forces. NORTHCOM coordinates with other combatant commands and intelligence agencies to identify and track threats before they reach U.S. territory.
Unlike other combatant commands that conduct offensive operations abroad, NORTHCOM focuses primarily on defensive operations within its area of responsibility. This includes coordinating the response to any attack on the homeland.
NORAD Partnership
NORAD is the binational U.S.-Canadian command responsible for aerospace warning, aerospace control, and maritime warning for North America. The NORAD agreement, first signed in 1958, represents one of the closest military partnerships between any two nations.
NORAD operates a network of sensors, aircraft, and command centers to detect and track aircraft, missiles, and space vehicles entering North American airspace. The command maintains 24/7 alert status with fighter aircraft ready to intercept and identify unknown aircraft.
The aerospace warning mission includes detecting, validating, and warning of attack against North America by aircraft, missiles, or space vehicles. This mission is critical to providing decision-makers with time to respond to potential attacks.
Current Threat Environment
NORTHCOM faces an evolving threat environment that includes advanced missile systems from nation-state adversaries, potential terrorist attacks, and emerging challenges in cyberspace and space domains. Russia and China both possess intercontinental ballistic missiles capable of reaching the United States.
The command has identified Russian long-range aviation and submarine patrols near North American airspace and waters as areas requiring continued monitoring. These patrols have increased in frequency compared to the immediate post-Cold War period.
Hypersonic weapons development by adversaries presents new challenges for homeland defense. NORTHCOM works with the Missile Defense Agency and Space Force to develop and deploy capabilities to address these emerging threats.
Defense Support to Civil Authorities
Beyond homeland defense, NORTHCOM provides Defense Support to Civil Authorities (DSCA) during domestic emergencies. This includes support during natural disasters, pandemic response, and other civil emergencies when requested by civilian authorities.
DSCA operations are conducted in support of lead federal agencies and must be requested through proper channels. Military support to civil authorities is governed by law and policy to ensure appropriate civilian control.
