Buckley SFB's host unit Space Base Delta 2 (SBD2) falls under the direction of the United States Space Force.

SBD2 is responsible for day-to-day support to the operational mission of Space Delta 4 (DEL 4) Missile Warning Delta. Buckley SFB and DEL 4 directly support Combatant Commands across the globe.

Buckley SFB is home to 117 tenant units including Space DELTA 4 Missile Warning, the 140th Air Wing, Colorado Air National Guard (COANG), the Navy Reserve Center Denver, 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 SFB truly represents a joint, Total Force and coalition base. This includes 3,500 active duty members from every service, 4,000 National Guard personnel and Reservists, four commonwealth international partners, 2,400 civilians, 2,500 contractors, 94,000 retirees and approximately 40,000 veterans and dependents. The base contributes over $2.5 billion annually to the local economy.

What is now Buckley Space Force Base started as Buckley Field, named for 1st Lt. John Harold Buckley, a World War One fighter pilot killed in combat on a strafing mission behind enemy lines on the Western Front in France. The city of Denver purchased the land and donated it to the Army in the early years of World War Two. The Army quickly established a large US Army Air Force Base, training over fifty thousand airmen through basic, and housing a technical training center for bombardier and armorer roles.

After World War II, Buckley became an auxiliary field for Lowry AFB, an Air National Guard Field, and then a Navy Air Station all in the space of three years. Buckley was renamed Naval Air Station Denver until the base was transferred to the US Air Force in 1959, when it became Buckley Air Force Base for a year, before becoming Buckley Air National Guard Base - the first stand-alone Air National Guard Base, home of the 120th Tactical Fighter Squadron. The 120th mobilized for operations for the Cuban Missile Crisis, the Vietnam War, and Operations Desert Storm, Northern Watch, and Iraqi Freedom.

Buckley returned to Air Force service in 2000 and witnessed a wave of modernization in commissary, dormitory, and housing facilities, as well as a base exchange and an expansion of mission facilities. Buckley became the base for the 460th Space Wing (previously the 460th Air Base Wing) in 2004, and for the next 16 years continued to host the Colorado Air National Guard while supporting more than 90 base partners located both on-base and in the local community. The 460th Space Wing was deactivated in July 2020, and in its place, Buckley Garrison was activated as a unit of the newly established United States Space Force. The Garrison provided installation support functions for the resident air operations, space-based missile warning capabilities, space surveillance operations, and space communications missions. 

Most recently, and during a historical U.S. Space Force ceremony, the Department of the Air Force renamed Buckley Air Force Base to Buckley Space Force Base on June 4, 2021.  The name change does not bespeak a change in Buckley’s mission, but rather signifies a realignment of our installation under the Space Force.  It also highlights the multi-faceted mission of the base and tenant units across multiple domains – Air, Space, Cyberspace, Land, and Sea.  The total-force integrated team is integral to the success of the missile warning mission along with the success of Team Buckley.
