We guard America’s skies every day, 24 hours a day. The men and women of the Western Air Defense Sector detect, identify, track and can scramble fighters to intercept unknown or threatening airborne objects.

Our team is a bi-national and joint service unit. Soldiers, sailors, airmen, Canadian Forces personnel, DoD civilians, and government contractors all comprise the WADS team. About 20% of the Western Air Defense Sector team are traditional Air Guardsmen who serve one weekend per month and two weeks a year. They typically have civilian professions, but can and have been called to active duty by the President. full-time occupations. In accordance with a Presidential order, the Sector Commander can mobilize all of our traditional Guard members as he would during any crisis or contingency.
