Headquartered at Peterson Space Force Base, Colorado, Space Base Delta 1 falls under the direction of Space Operations Command for its day-to-day operational missions, while it receives higher headquarters support for its base operations missions from Air Force Materiel Command as the Air Force servicing major command.
SBD 1 enables U.S. Space Force operations for 4 of the USSF Space Deltas and more than 114 other mission partners across 17 world-wide operating locations by providing integrated Base Operating Support (e.g., directly assisting, maintaining, supplying, and distributing support of forces at the operating location), Combat Service Support (e.g., the essential capabilities, functions, activities, and tasks necessary to sustain all elements of all operating forces at the operating location), and Delta Staff Agency services.
SBD 1 is unique in that it currently hosts real property at four installations to include Peterson SFB, Pituffik Space Base, Cheyenne Mountain Space Force Station, and the Maui Space Surveillance Complex (MSSC) on the summit of Haleakala, Hawaii. Today, SBD 1 is also responsible for ensuring installation support agreements with U.S. military installations in close proximity to an additional 29 geographically separated units reaching every corner of the globe.
SBD 1 hosts multiple, major mission partners to include: North American Aerospace Defense Command & U.S. Northern Command; U.S. Space Command; Space Operations Command and Space Training and Readiness Command; Army Space & Missile Defense Command; Joint Force Component Command for Integrated Missile Defense; the Air Force Reserve Command’s 302d Airlift Wing; and shared runway operations with the Colorado Springs Municipal Airport. In total, Space Base Delta 1 consists of over 2,800 military and civilian members who support nearly 17,000 personnel.
HISTORY
Peterson SFB traces its roots to the Colorado Springs Army Air Base, established on April 28, 1942, at the Colorado Springs Municipal Airport, which had been in operation since 1926. The base renamed to Peterson Army Air Base, also known as Peterson Field, Dec. 13, 1942, in honor of the late Army Air Forces 1st Lt. Edward J. Peterson.
On Dec. 31, 1945, shortly after the end of World War II, the Army inactivated the base returning the property to the city of Colorado Springs. In 1947, after the birth of the U.S. Air Force, the base reactivated from Sept. 29, 1947, to Jan. 15, 1948, and again from Sept. 22, 1948, into 1949.
The Air Force reactivated Peterson Field once more following the Jan. 1951 establishment of Air Defense Command at Ent AFB in Colorado Springs – now where the USA Olympic Training Center is located. The 4600th Air Base Group was designated as the 4600th Air Base Wing in 1958, and then predesignated as the 46th Aerospace Defense Wing April 1, 1975. On March 1, 1976, Peterson Field was renamed Peterson AFB.
1st Space Wing was activated Jan. 1, 1983 and the 46th Aerospace Defense Wing deactivated on Apr. 1, the same year. The 3rd Space Support Wing activated Oct. 15, 1986. These two wings deactivated May 15, 1992 and transferred to the newly activated 21st Space Wing.
Groundbreaking for a Consolidated Space Operations Center (CSOC) occurred at Falcon AFS on May 17, 1983. The facility was transferred to Space Command on September 26, 1985. The station became the location where the first independent satellite missions took place. On July 26, 2021, Schriever was officially renamed Schriever Space Force Base.
The station was later renamed Falcon Air Force Base on June 13, 1988.
The installation was renamed on June 5, 1998 in honor of Gen. Bernard A. Schriever, the man considered to be the “father” of the U.S. Air Force’s early ballistic missile and space programs. This marked the first time in U.S. Air Force history that an installation was named in honor of a person still living—Gen. Schriever was 87 years old at the time.
The USSF activated the Peterson-Schriever Garrison on July 22, 2020, merging the 21st and 50th Space Wings under one commander and creating a lean and agile structure for installation support. Both Peterson and Schriever AFB were renamed to Peterson and Schriever Space Force Base July 2021. P-S GAR was redesignated as Space Base Delta 1 on May 23, 2022 to better reflect their function and place within the service’s structure. Recognizing the increasing complexity and operational tempo of space missions, the Space Force activated Space Base Delta SBD 41 at Schriever Space Force Base on June 18, 2025. This activation enables greater focus and accountability in installation support by realigning responsibility for Schriever, Ka'ena Point SFS, Hawaii, and New Boston SFS, New Hampshire from SBD 1 to the newly formed SBD 41. This dedicated, on-site support is crucial for optimizing mission readiness across the Space Force
