Buckley Air Force Base was named after 1st Lt. John H. Buckley, a World War I flier from Longmont, Colo. In 1941 the city of Denver donated land to the War Department. A contract for $7.5 million and 700 structures was let in 1942 to build Buckley. The War Department transferred Buckley to the Colorado Air National Guard in 1946. The Department of Navy took over Buckley in 1947 and the installation was commissioned as Naval Air Station--Denver. Buckley NAS was subsequently decommissioned in 1959 and the COANG took charge of the installation again in 1960, designating it as Buckley Air National Guard Base. Buckley remained an Air National Guard base until Oct. 1, 2000 when the 821st Space Group became host and the base was renamed Buckley Air Force Base. The 460th Air Base Wing was activated Oct. 1, 2001, and assumed full control of the support mission in the Denver area. On Aug. 19, 2004, it was designated as the 460th Space Wing and added an operational space mission to its responsibilities. On July 17, 2020, the 460th Space Wing was re-designated as the Buckley Garrison. On May 23, 2022, Buckley Garrison was re-designated as Space Base Delta 2.
