Buckley AFB's host unit, Buckley Garrison, falls under the direction of the United States Space Force.
It is responsible for day-to-day support to the operational mission of the Space Delta 4 (DEL 4) Missile Warning Delta. Buckley Garrison and DEL 4 directly support Combatant Commands across the globe.
Besides being the home of Buckley Garrison, the base also hosts Space DEL 4 Missile Warning Delta, the 140th Wing, Colorado Air National Guard (COANG), the Navy Operational Support Center, the Aerospace Data Facility-Colorado, the Army Aviation Support Facility and the Air Reserve Personnel Center. These are also known as the "Big Six" mission partners at Buckley.
Buckley AFB truly represents a joint, Total Force and coalition base. This includes 3,100 active duty members from every service, 4,000 National Guard personnel and Reservists, four commonwealth international partners, 2,400 civilians, 2,500 contractors, 36,000 retirees and approximately 40,000 veterans and dependents. The base contributes an estimated $1 billion annually to the local economy.
Space Delta 4 (DEL 4) provides strategic and theater missile warning to the United States and our International Partners. It operates and supports three constellations of Overhead Persistent Infrared (OPIR) satellites and two types of Ground-Based Radars (GBRs) for the purpose of conducting strategic and theater missile warning.
Additionally, DEL 4 provides tipping and cueing to missile defense forces, battlespace awareness to Combatant Commanders and technical intelligence for further analysis. DEL 4 manages weapon system architectures and ensures operations are intelligence-led, cyber-resilient, and driven by innovation, while postured to operate in a contested, degraded, and operationally-limited environment. DEL 4 is one of eight mission-oriented Deltas within the United States Space Force.
