Space Base Delta 1
Space Base Delta 1 is a major command of the United States Space Force headquartered at Peterson Space Force Base, Colorado, tasked with delivering base operations support, combat service, and infrastructure to enable space warfighting capabilities for the Space Force, joint partners, and allies.[1] It manages key installations—including Peterson Space Force Base, Cheyenne Mountain Space Force Station, Pituffik Space Base, and the Maui Space Surveillance Complex—and geographically separated units, supporting nearly 17,000 personnel with a workforce of over 2,800 military and civilian members (as of 2025).[2] SBD 1 hosts critical mission partners such as the North American Aerospace Defense Command (NORAD), U.S. Space Command, Combat Forces Command, and the Army Space and Missile Defense Command, facilitating multi-domain operations and homeland defense.[1] The unit's mission focuses on providing world-class weapon-system infrastructure and combat support to ensure agile, uninterrupted service to warfighters, with core priorities including sustaining survivable power projection platforms, building a resilient Total Force through innovation and education, and delivering ready, lethal forces.[2] Under operational control of Combat Forces Command (formerly Space Operations Command until redesignated on November 3, 2025) and base support from Air Force Materiel Command, SBD 1 enables operations for 4 of the Space Force's space deltas and more than 114 mission partners across 17 worldwide locations (as of 2025).[3][2] Its functions encompass base operating support, combat service support, and delta staff agency services, emphasizing professional resilience and inclusiveness to support global space dominance.[2] Historically, SBD 1 traces its origins to the Colorado Springs Army Air Base established in 1942, evolving through various redesignations such as the 1st Space Wing (activated 1983, inactivated 1992) and the Peterson-Schriever Garrison before being officially redesignated as Space Base Delta 1 on May 23, 2022, to align with the Space Force's organizational structure.[1] This redesignation maintained its core role in supporting space missions while adapting to the demands of modern multi-domain warfare.[4] In June 2025, Space Base Delta 41 was activated at Schriever Space Force Base to handle support responsibilities there and certain geographically separated units, refining SBD 1's focus.[5] As of November 2025, SBD 1 is commanded by U.S. Space Force Col. Kenneth F. L. Klock, with Chief Master Sgt. Martha Burkhead serving as the senior enlisted leader, overseeing a structure that includes deputy commanders for key sites like Peterson and Cheyenne Mountain.[2]History
Origins of predecessor organizations
The origins of Space Base Delta 1 trace back to several key U.S. Air Force installations and units in Colorado Springs that laid the foundation for space operations. Colorado Springs Army Air Base was established on April 28, 1942, adjacent to the existing Colorado Springs Municipal Airport, which had operated since 1926, to serve as a training site for heavy bomber crews during World War II. On December 13, 1942, the base was renamed Peterson Army Air Base, also known as Peterson Field, in honor of 1st Lt. Edward Joseph Peterson, a Colorado native and operations officer of the 311th Bombardment Group who was killed in a B-17 Flying Fortress crash at the base on October 8, 1942.[6][7] Following World War II, Peterson Field transitioned through various roles, including pilot training and reserve operations, before focusing on continental air defense in the Cold War era. It supported early efforts in missile warning and space surveillance, hosting units that integrated radar and satellite data for detecting aerial threats. On March 1, 1976, the installation was officially renamed Peterson Air Force Base, reflecting its growing strategic importance under Air Force control.[6] Concurrently, the nearby Cheyenne Mountain Complex, constructed starting in 1961 and becoming operational in 1966, integrated North American Aerospace Defense Command (NORAD) functions, including space surveillance and missile warning, which expanded in the 1960s to monitor ballistic missile launches and satellite activities as part of U.S. defense against Soviet threats. The evolution toward dedicated space organizations accelerated in the 1980s. At Peterson AFB, the 1st Space Wing was activated on January 1, 1983, to oversee space warning and surveillance missions, replacing the 46th Aerospace Defense Wing and marking the base's shift to primary space operations. This unit was redesignated as the 21st Space Wing on May 15, 1992, continuing its focus on missile warning through ground-based sensors and satellite networks. Meanwhile, at Falcon Air Force Station (later Falcon AFB), the 2nd Space Wing handled satellite control from 1985, evolving into the 50th Space Wing, which was activated on January 30, 1992, to manage space launch and satellite operations for programs like the Defense Support Program and Global Positioning System.[6][8][9] Key naming milestones further highlighted the bases' space heritage. On June 5, 1998, Falcon AFB was renamed Schriever Air Force Base in honor of Gen. Bernard A. Schriever, the architect of the U.S. intercontinental ballistic missile program, making him the only living person at the time to have an Air Force base named after him. Gen. Schriever, who led Air Force Systems Command's space efforts from 1957 to 1961, died in 2005. The base was redesignated Schriever Space Force Base on July 26, 2021, aligning with the U.S. Space Force's emphasis on advanced satellite control and space domain awareness. These predecessor organizations at Peterson and Schriever, along with Cheyenne Mountain's command roles, provided the operational backbone for integrated space base functions.[10][11]Activation as Peterson-Schriever Garrison
The establishment of the U.S. Space Force on December 20, 2019, through the signing of the National Defense Authorization Act for Fiscal Year 2020 by President Donald Trump, initiated a comprehensive reorganization of U.S. Air Force space units to align with the new service branch's structure.[12] This legislative action transferred space-related missions, personnel, and assets from the Air Force to the Space Force, setting the stage for streamlined command and control to enhance space domain awareness and operations. On July 24, 2020, the Peterson-Schriever Garrison was activated during a virtual ceremony, marking the inactivation of the 21st Space Wing at Peterson Air Force Base and the 50th Space Wing at Schriever Air Force Base, Colorado.[13] The merger consolidated these predecessor organizations under a single commander to form a unified installation management entity, designed for lean and agile oversight of base operations across multiple sites.[14] Headquartered at Peterson Air Force Base, the garrison also assumed responsibility for Thule Air Base in Greenland, Cheyenne Mountain Air Force Station in Colorado, and Ka'ena Point Satellite Tracking Station in Hawaii.[15] The garrison's initial mission focused on delivering combat service support, base operations, and critical infrastructure to enable space missions for the Space Force and its partners.[16] Comprising over 2,800 military and civilian members, it provided world-class weapon-system infrastructure and support services to nearly 17,000 personnel across its installations, ensuring operational readiness for global multi-domain defense activities.[16] Upon activation, the Peterson-Schriever Garrison was assigned to Space Operations Command (SpOC), which oversees day-to-day operational missions for the Space Force.[16] Activated amid the COVID-19 pandemic, the garrison navigated early challenges in maintaining mission assurance while integrating with joint partners, including the North American Aerospace Defense Command (NORAD) hosted at Peterson Space Force Base.[17] It sustained essential support functions, such as health protections and operational continuity, for its personnel and critical "no-fail" missions like NORAD's 24/7 aerospace warning and control operations, despite pandemic-related disruptions like lockdowns and manning adjustments that began impacting the bases earlier in 2020.[18] These efforts underscored the garrison's role in fostering resilience during its formative phase.[19]Redesignation to Space Base Delta 1
On May 23, 2022, the Peterson-Schriever Garrison (P-S GAR) was officially redesignated as Space Base Delta 1 (SBD 1) during a ceremony at Peterson Space Force Base, Colorado, marking a key step in the U.S. Space Force's adoption of a standardized field organizational model based on deltas.[4][20] This transition aligned base support functions with the broader delta structure, replacing the "garrison" designation to better reflect SBD 1's role in providing integrated installation and mission support across the service.[1] The redesignation aimed to standardize base operations under the delta framework, enabling SBD 1 to facilitate U.S. Space Force activities for nine of the 13 Space Deltas (as of 2023), more than 111 mission partners, and the management of seven installations along with 17 geographically separated units worldwide.[21] This shift enhanced operational efficiency by centralizing support for diverse mission sets, including those under Space Operations Command and the North American Aerospace Defense Command, while adapting to the Space Force's evolving structure established since its 2020 activation.[4] Post-redesignation, SBD 1 expanded its scope to oversee global installations, such as Pituffik Space Base in Greenland and New Boston Space Force Station in New Hampshire, ensuring sustained support for remote and strategically vital sites.[1] By the end of 2023, its personnel had grown to over 4,300 military and civilian members, providing essential services to nearly 18,400 total personnel across these locations.[21] A notable event in this period was the July 11, 2024, change of command ceremony, where Col. David Hanson relinquished leadership of SBD 1 to Col. Kenneth Klock, underscoring the unit's continued maturation under the new designation.[22] In June 2025, to further distribute support responsibilities and enhance efficiency, Space Base Delta 41 was activated at Schriever Space Force Base, assuming management of certain base operations previously handled by SBD 1. This realignment reduced SBD 1's direct support to four Space Deltas and refocused its operations on four primary installations—Peterson Space Force Base, Pituffik Space Base, Cheyenne Mountain Space Force Station, and Maui Space Surveillance Complex—while maintaining oversight of 17 worldwide operating locations through support agreements for 29 geographically separated units. As a result, SBD 1's workforce adjusted to over 2,800 military and civilian members supporting nearly 17,000 personnel as of November 2025.[5][2]Mission and Role
