Peterson Space Force Base
View on Wikipedia
Peterson Space Force Base, previously Peterson Air Force Base, Peterson Field, and Army Air Base, Colorado Springs, is a United States Space Force base that shares an airfield with the adjacent Colorado Springs Municipal Airport and is home to the North American Aerospace Defense Command (NORAD), the Space Force's 21st Space Wing, elements of the Space Force's Space Systems Command, and United States Northern Command (USNORTHCOM) headquarters. Developed as a World War II air support base for Camp Carson, the facility conducted Army Air Forces training and supported Cold War air defense centers at the nearby Ent Air Force Base, Chidlaw Building, and Cheyenne Mountain Complex. The base was the location of the Air Force Space Command headquarters from 1987 to 20 December 2019 and has had NORAD/NORTHCOM command center operations since the 2006 Cheyenne Mountain Realignment placed the nearby Cheyenne Mountain Complex on standby. On 26 July 2021, the installation was renamed Peterson Space Force Base to reflect its prominent role in the new space service.[2]
Key Information
History
[edit]Colorado military construction during the buildup of US training installations prior to the bombing of Pearl Harbor included the 1940 Lowry bombardier school at Denver and Camp Carson south of Colorado Springs (HQ completed on 31 January 1942). Sites "in the vicinity of Colorado Springs" were assessed in the summer of 1941 for a USAAF airfield,[3] and during April 1942 the Photographic Reconnaissance Operational Training Unit (PROTU) was activated in a leased facility[where?] at Colorado Springs.[4] On 6 May 1942, the site adjacent to the airfield of the 1926 Colorado Springs Municipal Airport was selected,[5] and the airport's airfield was subsequently leased as an "air support field"* for Camp Carson under the "air support base development program". In May 1942, units such as the 5th Mapping Squadron (from Bradley Field) arrived and used city facilities. The "Second Photographic Group Reconnaissance" (activated 7 May 1942 at Will Rogers Field)[6] transferred to Colorado Springs, and the "2nd Group ... headquarters was situated in a former garage across the street from the Post Office, barracks were in the city auditorium ... and the mess hall was located at the busy horseshoe counter of the Santa Fe railway station."[7] Land at the Broadmoor was used for maneuvers, and the 2nd Group initially operated without aircraft.[7] Personnel[specify] were also "housed temporarily at Colorado College" and a youth camp near the Woodmen sanitorium.[8] (the 14th Photographic Reconnaissance Squadron was located at the Kaufman Building on Tejon St.)[9]
Army Air Base, Colorado Springs
[edit]"Army Air Base, Colorado Springs",* construction began after 10 May 1942, on "nothing more than a large patch of Colorado plain",[10] and the installation was placed under the Headquarters, United States "AAF [on] 11 June 1942".[5] The 373d Base HQ and Air Base Sq was activated[where?] as the base operating unit on 20 June 1942 (replaced by the 214th AAF Base Unit in 1944), and the base was assigned to the 2nd Air Force on 22 June 1942. On 7 July 1942, "HQ PROTU" was on the "Army Air Base, Colorado Springs" and was ordered to provide "four to five months of training to each individual".[10] During air base construction, the 20th Combat Mapping Squadron was activated on 23 July 1942, and used the Alamo Garage[11] on Tejon Street.[12] Runways were completed in August 1942,[8] and eponym 1st Lt Edward J. Peterson crashed 8 August 1942 on take off (1st Coloradoan killed at the airfield.)
Peterson Field
[edit]Peterson Field was the airfield named on 13 December 1942,[16] and included the runway used by both the municipal airport and the military installation:[17] "Army Air Base, Peterson Field", which had begun publishing the Wingspread base newspaper by 11 July 1942.[18] The "18 Dep Rpr Sq" was assigned to the military installation from 19 January – 29 April 1943, and the installation was assigned to the Third Air Force (5 March – 1 October 1943) and by the end of the 1943 summer had tar paper barracks, an officer's club, and a theater in a Quonset.[19] After the base transferred to Second Air Force on 1 October 1943,[5] in June 1944 Peterson Field began fighter pilot training[specify] with P-40N Warhawks.[16] "In March 1943 the Third Air Force took over the photographic reconnaissance Operational Training Unit which had been operating at Peterson Field ... under the direct control of the Director of Photography since April 1942".[20]
Bomber Commands
[edit]The 4th Heavy Bombardment Processing Headquarters ("4 H Bomb Processing HQ") was activated on 10 June 1943 (the 1st B-29 landed at Peterson Field in the summer of 1943),[19] and bomber training by the 214th AAF Base Unit (Combat Crew Training School, Heavy) B-24 Liberator)[failed verification] began after the 383rd Bombardment Group relocated from Geiger Field, Washington[16] on 26 October 1943. In 1944 (11 June – 20 October), the XXI Bomber Command was assigned to Peterson; and the "HQ and HQ Sq" of XXII Bomber Command was assigned 14 October 1944 – 13 February 1945, and by 17 August 1944, 4 bomb wings (313th through 316th) were assigned to the base — the last left on 7 June 1945.[5] The 263rd AAF Base Unit became the Peterson "base operating unit" on 8 March 1945 (transferred to Andrews Field on 17 March 1946).[5]: 8, 471 The Army Air Forces Instructor School[specify] opened at Peterson Field in April 1945,[16] and the base was one of several that transferred to Continental Air Forces on 16 April 1945. (VIII Bomber Command arrived 17 August 1945).
The base was inactivated 31 December 1945 after the 13th Bombardment Wing (17 October) and VIII Bomber Command (c. 15 December) departed, and site management by the base operating unit ended on 17 December 1945.[21] In 1946, Peterson's last AAF Base Units were discontinued: 260th AAF Base Unit (Fighter Wing) in January, the 202nd AAF Base Unit (Special) in February, and the 268th AAF Base Unit (Instrument Instructor Unit) in March and the 201st (Headquarters Base Unit) in April (the 72nd Fighter Wing was at the base from "4 January 1946 - 9 April 1946"). The 703rd AAF Base Unit (Hq, 53d AACS Group) moved to Kelly Field in February. Designated surplus on 29 July 1946,[5] "the U.S. Government returned control[specify] of the [air]field to the City of Colorado Springs".[22] Many of the base buildings were torn down.[22] In 1946, Tonopah AAF (Nevada, on 1 October), Clovis AAF (New Mexico, 16 October), and Casper AAF (Wyoming, on 15 December) became detached installations of the inactive base for a short period.
During planning for the new United States Air Force, Colorado's Arlington Auxiliary Army Airfield became a detached installation of the surplus base (1 January – c. 10 October 1947), and the "468th Construction Co (15th AF)" became the inactive base's operating unit in February 1947. The base with new construction was activated 29 September 1947 – 15 January 1948, then was "surplus"[5] until after the notice in November 1950 to reactivate Air Defense Command. The "23 Photo Sq 19 May 1943-9 August 1948" remained throughout both inactive/surplus periods, and the "4600 Maint & Sup Sq" was established at the surplus base on 1 December 1950).[5]
USAF installation
[edit]
The military base at the municipal field reactivated as an off-base installation of Ent Air Force Base on 1 January 1951 and was operated by Ent's 4600 Air Base Group.[5] After being assigned to Peterson on 1 March 1952,[5] the 4602d Air Intelligence Service Squadron had subordinate organizations at the "Defense Force Headquarters [on] Hamilton Air Force Base, California, at Kansas City, Missouri,[specify] and at Stewart Air Force Base" New York.[23] The 4600th Group became the 4600th Air Base Wing on 8 April 1958 (moved to Peterson on 18 October 1972).[24]: 40 The 4600th was replaced by the 46th Aerospace Defense Wing on 1 April 1975.[24] In January 1968, Air Training Command's 3253d Pilot Training Squadron at Peterson Field began light aircraft indoctrination for cadets. These operations moved to the United States Air Force Academy on 21 March 1974.[25] The military base at Peterson Field gained its own base commander[specify] on 28 February 1975.

Designated Peterson Air Force Base on 1 March 1975, when Ent AFB was being closed, Peterson was the last of the April 1945 Continental Air Forces airbases to be named an air force base. Also on 1 March, Peterson assumed several functions from Ent AFB, which became the "Ent Annex" of Peterson, 18 July 1975 – 7 February 1978[5] (Peterson's off-base "Temporary Military Facility" was opened for space training by 1986). During the first part of the reorganization that broke up ADCOM,[24]: 46 the base "transferred to the Strategic Air Command" on 1 October 1979[22] (units transferred included the 47th Comm Sq to AFCS and the 46th Wing and 4602nd Computer Services Sq to SAC).[24]: 47 ADCOM HQ offices at the Chidlaw Building became the Aerospace Defense Center at Peterson on 1 December 1979.
Peterson's NORAD COC Backup Facility achieved Full Operational Capability on 16 November 1982[26] from the Cheyenne Mountain Complex which was placed on warm standby.

The 1st Space Wing replaced the 46th Aerospace Defense Wing on 1 April 1983. Thereafter the 1st Space Wing transferred host unit responsibility to the 3d Space Support Wing activated on 15 October 1986. Army and other units transferred from the former Ent AFB Federal Building to Peterson Building 2[citation needed] (renamed the Eberhart-Findley Building in October 2012).[26] On 15 May 1992, the personnel and equipment of both the 1st SW and 3d SSW merged to become the 21st Space Wing. Peterson's Space Analysis Center was at the corner of Academy & Fountain Blvds by 2004 before moving on base to bldg 1470, and in 2004 the Space Operations School used a building along I-25 at Woodmen Drive.

The Cheyenne Mountain Realignment moved NORAD/USNORTHCOM operations to Peterson AFB in 2006. In 2006, the 76th Space Control Facility was constructed at Peterson [27] (the squadron activated 22 January 2008). The MAFFS aircraft that fought the 2012 Waldo Canyon fire and 2013 Black Forest fire at Colorado Springs flew from Peterson AFB.
Some buildings from the Second World War have survived. Buildings remaining in 1996 were "the terminal, now the Peterson Air and Space Museum, the Broadmoor hangar, and the Spanish House" next to the museum,[28] along with Building 391, Building 365, supply warehouses and office buildings, and aircraft hangars and maintenance shops.[8]
The base's Retiree Activities Office has the representative for the Air Force Retiree Council Area IV (Colorado, Nevada, Utah, and Wyoming).[29]
On 20 December 2019, Air Force Space Command was redesignated as the U.S. Space Force and elevated to become an independent military branch.[30] With the new military branch, the Fourteenth Air Force and its units became Space Force Space Operations Command and Air Force Space Command's headquarters was redesignated as the Pentagon.

[edit]Peterson Space Force Base
View on GrokipediaPeterson Space Force Base is a United States Space Force installation located in Colorado Springs, Colorado, that serves as the headquarters for Space Operations Command, the service's primary field command responsible for generating combat-ready space forces.[1]
Originally established on April 28, 1942, as Colorado Springs Army Air Base to support World War II training and operations, the facility evolved through Cold War-era air defense roles before focusing on space missions.[2]
Redesignated Peterson Air Force Base in the 1970s and transitioned to Space Force control in 2021, it now hosts Space Base Delta 1, which provides installation support for over 111 mission partners, including the North American Aerospace Defense Command, United States Northern Command, and United States Space Command.[3][4]
The base enables critical space operations such as domain awareness, satellite control, and missile warning, underpinning national defense in the space domain amid growing strategic competition.[5][6]
History
World War II Origins
Peterson Space Force Base originated as the Colorado Springs Army Air Base, established on April 28, 1942, adjacent to the existing Colorado Springs Municipal Airport to support World War II military aviation needs.[2][6] The base was developed primarily as an air support facility for the nearby Camp Carson, an Army training installation activated earlier that year, facilitating logistical and training operations amid the rapid U.S. military expansion following the Pearl Harbor attack.[2] On December 13, 1942, the installation was renamed Peterson Army Air Base (also known as Peterson Field) in honor of 1st Lieutenant Edward J. Peterson, Jr., a Colorado native and U.S. Army Air Forces officer who became the first fatality in a training accident at the airfield on August 8, 1942, when his aircraft crashed during a routine flight.[2][7] Initial operations focused on photographic reconnaissance training under the Provisional Reconnaissance Training Unit (PROTU), which prepared and deployed more than 20 squadrons for combat roles in aerial intelligence gathering.[2] By October 1943, the mission shifted to heavy bomber combat crew training, with the 383rd Bombardment Group conducting operations using Consolidated B-24 Liberator aircraft to simulate long-range bombing missions.[2] In July 1944, training transitioned to fighter pilot instruction under the 268th Army Air Forces Base Unit and the 72nd Fighter Wing, employing Curtiss P-40 Warhawk aircraft to prepare pilots for tactical air superiority roles.[2][6] The Army Air Forces Instructor School was established at the base in April 1945, enhancing advanced training capabilities as the war in Europe concluded.[2] The base was inactivated on December 31, 1945, with operations ceasing and the property reverting to civilian municipal control.[2]Cold War and Bomber Operations
During the immediate postwar period marking the onset of the Cold War, Peterson Field functioned as a key airfield facility supporting the Strategic Air Command's Fifteenth Air Force, which relocated its headquarters to Colorado Springs in 1946.[2] This arrangement enabled logistical and operational support for SAC's emerging strategic bomber fleet, integral to the U.S. nuclear deterrence posture against Soviet expansionism. The base hosted the 4104th Air Force Reserve Training Wing from February 1, 1947, to June 27, 1950, conducting reserve mobilization training that bolstered SAC's readiness for long-range bombing missions.[2] By the early 1950s, primary emphasis shifted to air defense under Air Defense Command, with interceptor squadrons operating fighters like the F-86 Sabre and F-89 Scorpion to counter potential Soviet bomber incursions, reflecting the base's evolving role amid escalating East-West tensions.[8] Bomber-related activities diminished as the facility prioritized radar surveillance and continental defense, though transient SAC bomber overflights and maintenance support persisted sporadically. The field was inactivated twice in the late 1940s for realignments but reactivated to sustain these defensive imperatives.[6] In a later Cold War development, control of Peterson AFB transferred to SAC on October 1, 1979, from Aerospace Defense Command, maintaining administrative oversight of air defense assets without introducing dedicated bomber wings or heavy operational commitments.[9] This brief tenure, lasting until the activation of Air Force Space Command in 1982, aligned base functions with SAC's broader strategic mission but emphasized continuity in surveillance and command roles rather than frontline bomber deployments.[8]Establishment of Space Command
On September 1, 1982, the United States Air Force activated Space Command as a major command headquartered at Peterson Air Force Base in Colorado Springs, Colorado, marking a pivotal shift toward dedicated military operations in the space domain.[2][10] This activation responded to the escalating strategic role of space assets during the late Cold War, including satellite-based reconnaissance, communications, and missile warning systems, which required centralized oversight beyond existing Air Force structures.[10] The command assumed responsibility for organizing, training, and equipping space forces, building on earlier ad hoc space activities at the base tied to North American Aerospace Defense Command (NORAD) operations.[2] On November 15, 1985, Space Command was redesignated Air Force Space Command (AFSPC) to reflect its expanded mission and alignment with unified combatant commands, including support for the newly established United States Space Command (USSPACECOM) that year.[10] AFSPC's headquarters remained at Peterson, where it oversaw the development of key capabilities such as intercontinental ballistic missile (ICBM) control and space surveillance.[2] Concurrently, the 1st Space Wing was activated on January 1, 1983, as the first operational unit under the command, focusing on space launch and control missions from facilities at Peterson and nearby sites.[2] By 1987, AFSPC's permanent headquarters facilities were fully operational at the base, solidifying Peterson's role as the epicenter of U.S. military space activities.[2] This establishment laid the groundwork for AFSPC's contributions to operations like Desert Storm in 1991, where space-based intelligence and navigation proved critical, demonstrating the command's evolution from conceptual framework to warfighting enabler.[11] The focus on empirical advancements in space technology, rather than unproven doctrines, underscored the command's emphasis on verifiable orbital mechanics and signal intelligence for national defense.[10]Post-Cold War Realignments
Following the dissolution of the Soviet Union in 1991, Peterson Air Force Base underwent significant realignments to prioritize space-based missile warning, surveillance, and control missions amid reduced emphasis on traditional air defense roles. The base's 21st Wing, previously focused on tactical fighter operations, was inactivated on December 19, 1991, as part of broader Air Force force structure reductions, but was swiftly redesignated and reactivated as the 21st Space Wing on May 15, 1992, consolidating space operations under Air Force Space Command (AFSPC).[12] This shift reflected the growing strategic importance of space assets demonstrated during the 1991 Gulf War, where Defense Support Program satellites provided early missile warnings, prompting AFSPC and the nascent 21st Space Wing to activate the 11th Space Warning Squadron to enhance theater missile defense integration. In the mid-1990s, further realignments emphasized space domain awareness, with the 21st Space Wing assuming oversight of ground-based electro-optical deep space surveillance systems and integrating data from global sensor networks for orbital tracking. The 3rd Space Operations Squadron, already operational at Peterson, completed full mission transfer for satellite control programs on July 11, 1991, transitioning from developmental to sustained operations amid post-Cold War budget constraints that favored multi-mission space platforms over legacy aircraft maintenance.[13] By the early 2000s, the wing expanded defensive space control capabilities, activating the 16th Space Control Squadron in May 2007 to counter emerging orbital threats, while the 4th Space Control Squadron relocated from Holloman Air Force Base to Peterson in 2011, bolstering electromagnetic warfare and space battle management units.[14] These changes aligned with AFSPC's doctrinal evolution toward integrated space superiority, supported by approximately 2,500 personnel focused on persistent vigilance rather than expeditionary airpower.[15] No major Base Realignment and Closure (BRAC) actions targeted Peterson during this era, unlike many continental U.S. installations downsized post-1991; instead, its infrastructure adapted to host AFSPC's expanding footprint, including relocations from Ent Air Force Base in the 1970s that were fully realized by the 1990s. This realignment preserved the base's role in national command structures, such as NORAD's space warning integration, while fiscal pressures from the 1990s peace dividend redirected resources toward cost-effective satellite-dependent operations over manned interceptors.[6]Creation of the United States Space Force
The United States Space Force was established on December 20, 2019, through the National Defense Authorization Act for Fiscal Year 2020, signed into law by President Donald Trump, marking the creation of the sixth independent military service branch focused on organizing, training, and equipping forces for prompt and sustained operations in the space domain.[16] This legislation transferred space warfighting functions from the U.S. Air Force, including those centered at Peterson Air Force Base, which had hosted Air Force Space Command headquarters since September 1, 1982.[2] In the initial organizational realignments following the Space Force's activation, the 21st Space Wing at Peterson AFB was inactivated on July 24, 2020, with its personnel and missions reassigned to new Space Force deltas to enhance operational focus on space domain awareness, satellite control, and missile warning.[17] Concurrently, Space Base Delta 1 was activated on July 22, 2020, to oversee installation management and support for Space Force units at Peterson, Schriever Space Force Base, and other locations, replacing prior Air Force wing structures.[18] Space Operations Command, the Space Force's primary field command for operational space forces, was formally activated at Peterson AFB on October 21, 2020, assuming responsibilities previously held by Air Force Space Command and integrating over 21,000 personnel into the new service.[19] This activation centralized command of space wings, squadrons, and sensor networks at Peterson, bolstering the base's role in national security space architecture amid growing threats from adversarial anti-satellite capabilities and space-based kinetic operations. On July 26, 2021, Peterson Air Force Base was officially redesignated as Peterson Space Force Base, alongside Schriever and Cheyenne Mountain facilities, to align nomenclature with the service's space-centric mission and reflect the transfer of more than 9,000 Air Force personnel to Space Force ranks at the installation.[20] These changes streamlined command lines, reduced bureaucratic overlap with the Air Force, and positioned Peterson as a cornerstone for Space Force growth, with ongoing expansions in cyber and intelligence integration.[17]Location and Infrastructure
Geographic and Climatic Features
Peterson Space Force Base lies in southeastern Colorado Springs, El Paso County, Colorado, at coordinates approximately 38°49′N 104°42′W and an elevation of 6,035 feet (1,840 meters) above mean sea level.[21][22] Positioned on a high plateau along the eastern edge of the Front Range of the Rocky Mountains, the base benefits from the region's elevated terrain, which rises gradually from the Great Plains to the west toward the mountainous foothills.[21] This geographic setting facilitates clear lines of sight for radar and satellite tracking while integrating with civilian aviation infrastructure through shared runways at Colorado Springs Airport.[21] The local climate is semi-arid continental, marked by low humidity, abundant sunshine averaging over 240 days per year, and significant diurnal temperature swings due to the high altitude and dry air.[23] Annual precipitation totals approximately 17 inches, concentrated in summer convective thunderstorms, with snowfall averaging 57 inches in winter months.[24] Mean annual temperature hovers around 50°F (10°C), with extremes ranging from winter lows of 20°F (-7°C) to summer highs of 84°F (29°C); July records the warmest averages at 84.8°F daytime highs, while December sees the coldest at 33°F daytime averages.[25][26] These conditions support consistent aerospace operations but require adaptations for high-altitude density effects on propulsion and occasional hazards like high winds or hail.[24]Key Facilities and Runway Operations

The Hartinger Building functions as the primary headquarters for the United States Space Command (USSPACECOM) and Space Operations Command (SpOC), facilitating strategic oversight of space forces and missions.[4] Adjacent facilities support the North American Aerospace Defense Command (NORAD) and United States Northern Command (NORTHCOM), enabling integrated air, space, and missile defense operations from Peterson's central location.[4] Space Base Delta 1, the installation's host organization, manages base support infrastructure, including security facilities, armories, and military working dog kennels operated by the 21st Security Forces Squadron.[27] The airfield at Peterson SFB operates as a joint-use facility shared with the Colorado Springs Municipal Airport, with the city owning and maintaining the runways, taxiways, and associated infrastructure, while the base controls its dedicated military ramp.[28] Key runways include the parallel 17L/35R at 13,500 feet by 150 feet and 17R/35L at 11,022 feet by 150 feet, both surfaced in grooved asphalt and capable of supporting heavy aircraft with single-wheel load limits up to 120,000 pounds.[29] A crosswind runway further enhances operational flexibility. Military flightline activities focus on support aircraft, such as C-130H Hercules transports from the 302nd Airlift Wing, which conduct airlift missions and training exercises from the north apron reserved for military use.[30] These operations average routine taxiing and departures coordinated between base personnel and civilian air traffic control to ensure seamless joint usage.[28]Support Infrastructure
Space Base Delta 1 (SBD 1), headquartered at Peterson Space Force Base, oversees the base's support infrastructure, providing essential services such as civil engineering, logistics, contracting, and security forces to enable mission operations for over 10 Space Force deltas and more than 111 mission partners across 22 tenant organizations.[31][32] SBD 1's priorities include infrastructure sustainment and recapitalization for weapon system operations, alongside base-wide support encompassing facility maintenance, utilities, and real property management across Peterson, Schriever Space Force Base, Cheyenne Mountain Space Force Station, and Pituffik Space Base.[3][33] Civil engineering efforts under SBD 1 focus on modernizing facilities to address aging infrastructure challenges, including a recent civil engineering award aimed at enhancing base readiness through targeted upgrades.[34] These initiatives sustain critical systems like electrical grids, HVAC, and structural integrity, ensuring operational continuity for space domain awareness and command functions hosted at Peterson.[35] Logistics support is managed by the 21st Logistics Readiness Squadron (21 LRS), which handles supply chain operations, equipment deployment, and innovative solutions such as space logistics challenges to streamline materiel distribution for Space Force units.[36][3] Security infrastructure falls under the 21st Security Forces Squadron, responsible for perimeter defense, access control, and resource logistics to protect base assets amid increasing operational demands.[35] Contracting functions procure and manage services for infrastructure projects, while installation support agreements with proximate U.S. military sites ensure shared resource efficiency, such as utilities and emergency response.[31] Overall, these elements form a resilient backbone, adapting to Space Force growth since 2019 by prioritizing empirical needs over legacy Air Force models.[37]Mission and Operations
Role in Space Domain Awareness
Peterson Space Force Base hosts the headquarters of Space Delta 2, a key component of the U.S. Space Force's Space Operations Command responsible for generating, presenting, sustaining, and improving combat-ready forces for space domain awareness (SDA) operations.[38] SDA at Peterson encompasses tracking and cataloging space objects, fusing sensor data, and providing situational awareness to support U.S. interests in space.[38] This includes monitoring approximately 44,700 space objects, comprising 8,900 active payloads, 16,600 analyst objects, and 19,200 debris items, derived from U.S., joint, multinational, and commercial sensors.[38] The base's SDA efforts produce a comprehensive space catalog distributed publicly through platforms like space-track.org, enabling threat identification, characterization, and mitigation.[38] Space Delta 2, redesignated on July 24, 2020, with operational roots tracing to 1942, operationalizes SDA to exploit opportunities and counter vulnerabilities in the space domain.[38] These activities integrate with broader U.S. Space Command functions at Peterson, enhancing joint warfighter capabilities against space threats.[5] Key units under Space Delta 2 at Peterson include the 18th Space Defense Squadron, designated as the Space Force's premier SDA squadron, which focuses on detecting, tracking, and identifying objects to deliver timely space situational awareness data.[39] This squadron contributes to space battle management by processing data from the global Space Surveillance Network, supporting missile warning and defensive operations.[39] Overall, Peterson's infrastructure enables dispersed SDA operations across multiple global sites, ensuring persistent vigilance over the space environment.[5]NORAD and NORTHCOM Integration
Peterson Space Force Base hosts the headquarters for the North American Aerospace Defense Command (NORAD) and United States Northern Command (USNORTHCOM), serving as the primary site for their day-to-day operations and command center functions.[40] The base's NORAD and USNORTHCOM Command Center functions as the central "watch" for monitoring aerospace threats, air sovereignty, and homeland defense across North America, with real-time integration of data from multiple sources.[40] Cheyenne Mountain Space Force Station, located nearby, operates as an alternate command center and crew training facility, providing redundancy while Peterson handles routine mission execution.[41] In May 2008, NORAD and USNORTHCOM unveiled a fully integrated command center at Peterson, consolidating operations previously divided between locations and domains.[42] This facility fuses intelligence across land, air, space, missile warning, maritime, and cyber domains, enabling unified threat detection and response under a shared commander—a structure established since USNORTHCOM's creation in 2002.[42] Space and missile warning capabilities, reliant on satellite-based infrared sensors for ballistic missile detection, are embedded in this center, supporting NORAD's aerospace warning mission by providing early indications of launches targeting North America.[43] The integration at Peterson enhances operational efficiency through co-location with Space Force units under Space Base Delta 1, which provides base support and security for these commands.[44] This arrangement allows seamless incorporation of space surveillance data into broader defense postures, including missile warning and domain awareness feeds that inform USNORTHCOM's homeland security responsibilities.[45] The 21st Security Forces Squadron further bolsters this by securing nuclear command, control, and communications pathways critical to both organizations.[45]Strategic Contributions to National Security
Peterson Space Force Base hosts the headquarters of United States Space Command (USSPACECOM), which plans, executes, and integrates military spacepower into multi-domain global operations to deter conflict, defeat aggression, and deliver space combat power.[46][47] USSPACECOM's efforts emphasize space superiority, providing joint and combined forces with capabilities for domain protection and defense against emerging threats from adversarial actors developing anti-satellite weapons and other space denial technologies.[48] By December 2023, USSPACECOM achieved full operational capability, enabling it to support theater operations worldwide through assured space access and effects delivery.[48] Space Operations Command (SpOC), also headquartered at the base since its activation on October 21, 2020, generates combat-ready space, cyber, and intelligence forces while providing essential functions such as space domain awareness (SDA), missile warning, satellite communications, and command and control.[17][1] These operations contribute to national security by maintaining situational awareness of over 27,000 trackable objects in orbit, mitigating collision risks, and characterizing potential threats to U.S. space assets.[5] SpOC's Mission Delta 2 specifically conducts SDA to identify opportunities and vulnerabilities, enforcing space battle management and raising warnings of natural and man-made hazards.[5] In alignment with the National Defense Strategy, Peterson-based commands unify missile warning, defense, and SDA under USSPACECOM's Global Sensor Architecture, assumed in May 2023, to detect and counter ballistic missile launches, thereby bolstering homeland defense against strategic threats like those from North Korea.[49][50][51] This integration enhances deterrence and responsiveness, ensuring space-enabled precision in navigation, timing, and intelligence that underpin all U.S. military domains.[52]Based Units and Personnel
