140th Wing

The 140th Wing is a unit of the Colorado Air National Guard, headquartered at Buckley Space Force Base in Aurora, Colorado, comprising approximately 1,600 personnel across five groups, 12 squadrons, and two geographically separated units that deliver fighter, space-based missile warning, and civil engineering support for global and domestic missions.^[1]^[2] With roots established in 1923, its 120th Fighter Squadron became the first Air National Guard unit to receive federal recognition on June 30, 1946; the wing has a storied history of operational contributions, including the 120th Fighter Squadron's combat deployment to Vietnam in 1968—the first such ANG mission since World War II—and subsequent rotations to Iraq, Djibouti, Korea, and Japan from 2003 to 2019.^[1] Its core fighter operations are conducted by the 120th Fighter Squadron using F-16C+ Fighting Falcon aircraft equipped with LITENING II and SNIPER targeting pods for precision-guided strikes, providing Air Sovereignty Alert coverage for 24/7 airborne threat protection over the central United States, while the 233rd Space Group (as of early 2025) handled space control and early-warning missions focused on missile warning; these space missions transitioned to the United States Space Force in October 2025.^[1]^[2] The 240th Civil Engineer Flight supports U.S. Pacific Command with engineering expertise and contributes to the wing's readiness for state emergencies.^[1]^[2] Additional facilities are located at Greeley Air National Guard Station and Peterson Space Force Base in Colorado Springs, with training at the Airburst Range.^[1] Recent bipartisan legislation in the FY2025 National Defense Authorization Act supports recapitalization efforts for the wing's aging F-16 fleet by requiring the Air Force to consider Air National Guard units in future fighter aircraft allocations.^[3]

Overview

Mission and Capabilities

The 140th Wing of the Colorado Air National Guard executes a dual federal-state mission, providing air superiority, interdiction, space-based missile warning, space launch support, nuclear detection, and civil engineering capabilities for both national defense and state emergencies.^[1] When federalized, the wing falls under the operational control of Air Combat Command, enabling it to support combatant commanders worldwide with expeditionary forces, while in state status, it responds to Colorado-specific contingencies such as natural disasters and homeland security operations.^[2]^[1] In its fighter operations, the 140th Wing employs F-16C+ Fighting Falcon aircraft for air-to-air combat and air-to-ground interdiction, emphasizing roles in Air Sovereignty Alert to defend North American airspace and providing close air support during global deployments.^[2]^[4] The wing's space components, including the 233rd Space Group, previously delivered real-time missile warning, space launch assistance, and nuclear detonation detection to the National Command Authority via satellite monitoring using the Mobile Ground System (MGS); however, the MGS was decommissioned on May 13, 2025, and as of November 2025, the group is transitioning to a new mission assignment.^[5]^[6] Complementing these, the civil engineering elements focus on rapid infrastructure construction, base recovery, and contingency support to sustain operations in austere environments.^[1] A notable recent highlight includes the wing's leadership in the inaugural Expeditionary Air Base mission in March 2025, where over 120 personnel from all five groups deployed to establish and operate a forward operating base, demonstrating integrated multi-domain support for joint forces.^[7] This deployment underscored the wing's versatility in providing agile, scalable capabilities to enhance U.S. military readiness and deterrence.^[7]

Current Personnel and Composition

The 140th Wing consists of approximately 1,600 Airmen, including traditional Air National Guard members, active-duty associates, Active Guard and Reserve personnel, and full-time support staff who enable its composite missions across air, space, and civil engineering domains.^[1]^[2] These personnel are distributed across traditional part-time roles that balance civilian careers with military service, full-time positions for operational continuity, and associated active-duty elements that enhance training and readiness integration.^[5] The wing's overall structure comprises five groups, 12 squadrons, and two geographically separated units (GSUs), supporting missions for Air Combat Command and Pacific Air Forces (U.S. Air Force), and the U.S. Space Force.^[1]^[8] This composite organization allows the 140th Wing to maintain a diverse footprint, with primary operations at Buckley Space Force Base in Aurora, Colorado, and GSUs at Greeley Air National Guard Station and Peterson Space Force Base.^[1] Key groups within the wing include the 140th Operations Group, which oversees fighter operations; the 233rd Space Group, focused on space domain awareness and previously missile warning missions at Greeley ANG Station with over 300 Airmen, currently in transition following the May 2025 decommissioning of the MGS; the 140th Mission Support Group, providing base services and logistics; the 140th Medical Group, delivering healthcare and readiness support; and the 140th Maintenance Group, responsible for aircraft and equipment sustainment.^[1]^[5]^[9]^[6] Among its squadrons, the 120th Fighter Squadron, part of the 140th Operations Group, conducts F-16 operations at Buckley Space Force Base, emphasizing air superiority and ground attack roles.^[10] The 137th Space Warning Squadron, aligned under the 233rd Space Group, previously provided critical missile warning capabilities via the MGS until its decommissioning in May 2025 and is awaiting a new mission.^[1]^[6] Additionally, the 240th Civil Engineer Flight supports Pacific Air Forces with engineering, construction, and operational planning expertise from a GSU location.^[1]

History

Origins and Activation (1923–1950)

The origins of the 140th Wing trace back to the establishment of the Colorado Air National Guard's earliest aviation unit on June 27, 1923, when the 120th Aero Observation Squadron of the 45th Division Aviation was mustered into service as part of the Colorado Army National Guard.^[11] This squadron began with a modest force of 8 officers and 50 enlisted personnel, initially equipped with Curtis JN-4E (Jenny) biplanes for observation missions, though these aircraft proved challenging at Denver's high elevation.^[11] By 1924, the unit had relocated to Lowry Field—named in honor of 2nd Lt. Francis B. Lowry, a World War I casualty—and began transitioning to more suitable observation aircraft, including the Douglas O-2, Consolidated O-17, Douglas O-38, and eventually the advanced O-47, a three-seat, all-metal, single-engine monoplane that enhanced reconnaissance capabilities as tensions rose in the late 1930s.^[11] On January 6, 1941, amid escalating global conflicts, the squadron was mobilized for federal service with a strengthened roster of 19 officers and 116 enlisted members, marking its entry into World War II preparations.^[11] The unit relocated temporarily to Biggs Field in Texas for training, but following the attack on Pearl Harbor, it was disbanded, with its personnel reassigned throughout the Army Air Forces to support the war effort.^[11] This dissolution reflected the broader integration of National Guard aviation assets into active-duty forces during the conflict. In the postwar period, the Colorado Air National Guard emerged as a distinct branch in 1946, prompting the reorganization of the 120th Squadron as the 120th Fighter Squadron, equipped with P-51D Mustangs for air defense roles and earning distinction as the first federally recognized fighter unit in the Air National Guard.^[11] On October 1, 1946, the 140th Fighter Group was formed at Buckley Field—renamed from Buckley Army Air Field—and received federal recognition, providing the foundational command structure that would evolve into the modern 140th Wing.^[1] The group operated from Buckley Field through 1950, focusing on readiness and transitioning from observation to fighter operations amid the early Cold War tensions.^[1]

Korean War and Early Cold War (1951–1960)

In response to the escalating demands of the Korean War, the 140th Fighter Wing was federalized and placed on active duty with the U.S. Air Force on April 1, 1951.^[12] This marked the unit's first major federal activation, drawing on its Colorado Air National Guard roots to support national defense needs. Shortly thereafter, on April 12, 1951, the wing was redesignated as the 140th Fighter-Bomber Wing under Tactical Air Command, reflecting its evolving tactical role.^[12] The wing relocated to Clovis Air Force Base (now Cannon Air Force Base) in New Mexico on April 12, 1951, where it established operations and conducted intensive training to prepare for potential combat deployment.^[12] Although the full unit did not deploy overseas as a cohesive formation, individual pilots from the 120th Fighter Squadron were mobilized to Korea in April and May 1951, contributing to air operations against North Korean and Chinese forces.^[11] Under the command of Brigadier General Joe C. Moffitt—the first Air National Guard general to lead an active-duty wing—the 140th Fighter-Bomber Wing maintained the base through December 31, 1952, focusing on fighter-bomber readiness and support for the war effort during its 21-month active-duty period.^[12] Released from federal active duty on November 15, 1952, the wing returned to Colorado Air National Guard control and relocated back to Buckley Field (now Buckley Space Force Base) in Aurora, Colorado, effective January 1, 1953.^[12] This period initiated a shift toward continental air defense missions amid rising Cold War tensions. Equipped with F-80 Shooting Star jet fighters from 1953 to 1958, the unit honed interceptor skills, redesignated as the 140th Fighter-Interceptor Wing on July 1, 1955.^[12] By 1958, it transitioned to F-86 Sabre interceptors, enhancing its all-weather air defense capabilities until 1960.^[12] Assigned to Air Defense Command effective July 1, 1957—when it was redesignated the 140th Air Defense Wing—the unit emphasized radar-guided interception and rapid response to potential aerial threats over the continental United States.^[12] A notable highlight was the formation of the "Minutemen" precision aerobatic team in fall 1956, using F-80C aircraft to perform over 100 demonstrations nationwide.^[11] Federally recognized as the official Air National Guard aerial demonstration team, the Minutemen showcased the wing's proficiency until disbanding in 1960, underscoring the unit's dual role in operational readiness and public outreach during the early Cold War.^[12]

Vietnam War and Mid-Cold War (1961–1989)

In response to escalating tensions during the Berlin Crisis, the 140th Fighter Wing was federalized on October 1, 1961, and placed under the command of the Air Defense Command to bolster continental air defenses, with its F-102 Delta Dagger-equipped squadrons contributing to readiness operations until its release in August 1962.^[11] Similarly, amid the Cuban Missile Crisis, the wing was again mobilized in October 1962, deploying personnel and assets to enhance U.S. air defense postures against potential Soviet threats, demonstrating its role in rapid crisis response during the early Cold War.^[11] These activations underscored the wing's evolution from air defense interceptor missions to broader tactical capabilities, as it was redesignated the 140th Tactical Fighter Wing on January 1, 1961, and transitioned to the F-100 Super Sabre for supersonic fighter-bomber operations under Tactical Air Command.^[12] The wing participated in exercises like NATO's Deep Furrow at Incirlik Air Base, Turkey, in October 1967, which foreshadowed its sustained Cold War commitments.^[13] The wing's most significant Vietnam War involvement began with its federalization on January 25, 1968, in support of Operations Niagara and Rolling Thunder, during which it was redesignated the 140th Tactical Fighter Wing and its 120th Tactical Fighter Squadron deployed 20 F-100C Super Sabres to Phan Rang Air Base, South Vietnam, marking the first Air National Guard fighter squadron combat deployment of the conflict.^[13] Over the ensuing 15 months, approximately 900 wing members served, with 250 directly in theater flying more than 6,000 combat sorties, including close air support and interdiction missions against North Vietnamese supply lines, while enduring two aircraft losses to enemy action.^[14] For its valor, the wing earned the Air Force Outstanding Unit Award with "V" device, highlighting its contributions to tactical airpower in Southeast Asia before returning to state control on April 30, 1969.^[12] Post-Vietnam, the 140th Tactical Fighter Wing resumed F-100 Super Sabre operations for tactical training and alert duties.^[12] By April 1974, it transitioned to the LTV A-7D Corsair II, enhancing its close air support and precision strike capabilities, and achieving recognition as world champions in the inaugural Gunsmoke competition that year.^[10] This period saw increased overseas deployments, including the landmark September 1977 participation in exercise Coronet Ante at Gilze-Rijen Air Base, Netherlands—the first U.S. Air National Guard unit to deploy to Europe since Vietnam—where A-7D pilots conducted joint training with NATO allies and earned another Air Force Outstanding Unit Award in 1980.^[12] Throughout the mid-Cold War, the wing maintained rotational commitments under programs like Coronet Cove, beginning with its inaugural December 1978 deployment to Howard Air Force Base, Panama, to defend the Panama Canal Zone, followed by approximately 11 rotations through the 1980s providing air defense and reconnaissance support.^[12] Additional exercises reinforced its NATO focus, such as Coronet Rider at Merzifon Air Base, Turkey, in September-October 1979—the first base-to-base ANG deployment—and Coronet Bronco at Eskisehir Air Base, Turkey, in 1984, both emphasizing interoperability and tactical proficiency amid heightened East-West tensions.^[12] These operations solidified the wing's role in global deterrence, transitioning from Vietnam-era combat to sustained forward presence without further major mobilizations until the late Cold War.^[11]

Post-Cold War Transition (1990–2001)

Following the end of the Cold War, the 140th Tactical Fighter Wing underwent significant modernization efforts, beginning with the retirement of its A-7D Corsair II aircraft in March 1992. This marked the conclusion of nearly two decades of service with the A-7D, which had been the wing's primary attack platform since 1974. Concurrently, the unit transitioned to the F-16C/D Fighting Falcon under the oversight of Tactical Air Command, receiving its first Block 30 F-16s in September 1991 and achieving full operational capability by early 1992. This upgrade enhanced the wing's multirole capabilities, including air-to-air and air-to-ground missions, aligning with post-Cold War demands for versatile fighter operations.^[12]^[15] The wing participated in several key deployments during this period to support U.S. enforcement of no-fly zones over Iraq. In April 1995, elements deployed to Incirlik Air Base, Turkey, for Operation Provide Comfort II, contributing to humanitarian aid and enforcement efforts for Kurdish refugees following the Gulf War. Subsequent rotations included support for Operation Southern Watch, with deployments to Al Jaber Air Base, Kuwait, in June 1996 and January 1998, where F-16s conducted patrols and strikes to maintain the southern no-fly zone. In 2000, the wing returned to Incirlik for Operation Northern Watch, focusing on the northern Iraqi no-fly zone to deter aggression against Kurdish populations. These missions underscored the wing's role in expeditionary operations amid the drawdown of Cold War-era forces.^[15] Organizational changes reflected the evolving mission landscape. On March 15, 1992, the unit was redesignated as the 140th Fighter Wing, and on July 1, 1995, it became the 140th Wing to accommodate broader responsibilities beyond tactical fighters. A significant expansion occurred with the activation of the 137th Space Warning Squadron on October 1, 1995, in Greeley, Colorado, integrating space-based missile warning into the wing's portfolio as the first Air National Guard unit to assume such a strategic role under Air Force Space Command. This addition provided survivable detection of ballistic missile launches, enhancing national defense capabilities.^[12]^[16] Pre-9/11 activities included Theater Security Packages to bolster alliances and deterrence. In March 1995, the wing deployed to Australia for joint training with the Royal Australian Air Force, strengthening Pacific partnerships. European engagements featured participation in NATO's Coronet Blade exercise at Karup Air Base, Denmark, in August 1997, along with training detachments to Germany for interoperability with Luftwaffe MiG-29 units. These rotations honed combat readiness in forward environments. Additionally, Buckley Air National Guard Base completed its transition to full Air Force base status, redesignated as Buckley Air Force Base on October 1, 2000, reflecting the growing active-duty presence and infrastructure expansions at the installation.^[15]^[17]

Global War on Terror and Modern Operations (2001–Present)

Following the September 11, 2001, terrorist attacks, the 140th Wing was immediately activated to support Operation Noble Eagle, the U.S. military's air sovereignty mission, with its F-16 Fighting Falcon aircraft providing continuous combat air patrols over key U.S. airspace, including the National Capital Region and high-profile events nationwide.^[18]^[19]^[4] This ongoing commitment has maintained 24/7 alert status for the wing's fighters since 2001, ensuring rapid response to potential aerial threats across North America.^[10] The wing's involvement in the Global War on Terror expanded through multiple expeditionary deployments supporting Operations Enduring Freedom and Iraqi Freedom, including a 2003 activation to secure western Iraq and subsequent six-month rotations to the region through 2009, where personnel from the 120th Fighter Squadron and support units flew combat sorties and provided close air support.^[20]^[21] Additional rotations included operations in Djibouti from 2012 to 2017, where the wing's aviation package supported U.S. Central Command missions from Camp Lemonnier, focusing on counterterrorism and regional stability.^[1] Between 2015 and 2017, the 140th Wing contributed to Theater Security Packages in the Indo-Pacific, deploying approximately 250 Airmen and F-16s to Kadena Air Base in Japan and other locations to deter aggression and enhance allied interoperability.^[22]^[23] In 2019, over 300 wing members deployed to Bagram Air Base in Afghanistan for Operation Freedom's Sentinel, supporting NATO's Resolute Support Mission by training Afghan forces and conducting advisory operations.^[10]^[24] Recent operations have sustained the wing's combat tempo, including a 2021 deployment of its aviation package to conduct missions in support of U.S. Central Command objectives.^[1] In May 2025, more than 120 personnel from across the wing's groups deployed globally as the lead element for an Expeditionary Air Base under the Air Force Force Generation model, marking the Colorado Air National Guard's first such leadership role in establishing and operating a forward operating location for joint forces over six months.^[7] In March–April 2025, nearly 200 Citizen-Airmen participated in Exercise Red Flag 25-2 at Nellis Air Force Base, Nevada, testing adversarial deterrence in a large-scale combat training scenario. In June 2025, the wing executed Exercise Centennial Strike, simulating rapid mobilization of its Mission Generation Force Element to deploy and regenerate forces in a contested environment.^[25]^[26] In parallel with these air operations, the 140th Wing has evolved to incorporate expanded space domain roles through its 233rd Space Group, activated in 2013, which provided missile warning via the unique Mobile Ground System until its retirement in August 2025, and continues to support space situational awareness and U.S. Space Command missions.^[5]^[6] This growth aligns with the redesignation of Buckley Air Force Base as Buckley Space Force Base on June 4, 2021, enhancing the wing's integration with active-duty Space Force units on the installation, though discussions continued into 2025 regarding potential transfer of space missions to the U.S. Space Force.^[27]^[28] The wing has also developed associate relationships with active and reserve components, enabling shared operations in both air and space domains to optimize resources and readiness.^[27]

Organization

Command and Support Structure

The 140th Wing operates under a dual-hatted command structure, reporting to the Colorado Adjutant General for state missions and to Air Combat Command for federal operations as part of the Air National Guard's integrated framework. The wing is led by a wing commander, typically holding the rank of colonel, who oversees approximately 1,600 personnel across diverse missions. Colonel Ben Couchman serves as the wing commander, having succeeded Colonel Jeremiah Tucker in November 2024, with Chief Master Sergeant Byron Phillips as the command chief.^[8] The broader Colorado Air National Guard, which includes the 140th Wing, is commanded by the Assistant Adjutant General for Air, currently Brigadier General D. Micah Fesler, who provides strategic oversight from Buckley Space Force Base. Support for the wing's operations is provided by three primary groups focused on non-combat functions. The 140th Mission Support Group delivers essential logistics, security, and services to ensure wing deployability and base sustainment, including procurement, transportation, fuels management, force protection, personnel services, and infrastructure maintenance through its squadrons. The 140th Medical Group maximizes medical readiness for wing personnel by operating a clinic that conducts physical examinations, immunizations, bioenvironmental engineering, and occupational health programs, while also maintaining a specialized detachment for chemical, biological, radiological, and nuclear incident response. The 140th Maintenance Group sustains aircraft readiness with intermediate and flight-line maintenance for F-16C+ fighters, alongside back-shop operations for component repairs in propulsion, avionics, and related systems. Administrative roles within the wing emphasize seamless integration with state emergency management and reliance on full-time staffing. The 140th Civil Engineer Squadron, under the Mission Support Group, handles environmental compliance, emergency management, and explosive ordnance disposal to support Colorado's disaster response efforts. The wing employs full-time Active Guard Reserve members and federal technicians in key positions to maintain continuous operations, including maintenance, medical, and support roles that bridge traditional part-time Guard duties with daily requirements. In the 2010s, the 140th Wing saw discussions on expanding associate units with active-duty and reserve components to enhance mission integration, as highlighted during a 2014 visit by the Air National Guard director, who emphasized future growth in such partnerships to bolster capabilities across combatant commands.

Operational Units and Squadrons

The 140th Wing's core flying operations are centered on the 120th Fighter Squadron, known as the "Redeyes," which traces its lineage to the 120th Aero Observation Squadron established on June 27, 1923.^[10]^[11] This squadron, assigned to the 140th Operations Group at Buckley Space Force Base, Aurora, Colorado, transitioned to operating F-16C/D Fighting Falcons in 1992 and maintains responsibility for fighter training, air-to-air and air-to-ground missions, and homeland defense alert duties.^[10]^[29] Since September 11, 2001, the squadron has continuously supported air sovereignty alerts, contributing to national defense operations.^[30] In space operations, the 233rd Space Group, headquartered at Greeley Air National Guard Station, Colorado, oversees strategic space warning capabilities with nearly 400 personnel, including dual-status technicians, Active Guard Reserve, and traditional Guard members.^[5]^[31] The group was officially activated on March 10, 2013, reorganizing the prior 137th Space Warning Squadron to expand its structure into a full group with subordinate units focused on missile warning and space support.^[31]^[32] The 137th Space Warning Squadron, the group's primary operational element and the Air National Guard's first space unit federally recognized in October 1995, provides 24/7 mobile ground system monitoring for worldwide missile launches via satellite, space launch notifications, and nuclear detonation detection to support national command authorities.^[33] This evolution from an initial tenant intelligence and air control role in the early 1990s to a dedicated space warning mission in the mid-2000s enhanced the unit's integration with Air Force Space Command objectives.^[32]^[34] The wing's engineering capabilities are embodied in the 240th Civil Engineer Flight, a specialized 40-person unit under the 140th Mission Support Group that delivers expertise in operational planning, facility design, construction management, and emergency response for contingencies across multiple theaters.^[1]^[35] This flight supports wartime engineering tasks, including rapid infrastructure development and environmental compliance for Air National Guard operations. Beyond these primary units, the 140th Wing encompasses 12 squadrons in total, including support elements under the operations and mission support groups such as the 140th Communications Flight, which provides secure information systems and network capabilities, and the 233rd Space Communications Squadron, focused on satellite communications for space missions.^[1]^[36]

Facilities

Primary Installation

Buckley Space Force Base, located in Aurora, Colorado, serves as the primary installation for the 140th Wing of the Colorado Air National Guard. Spanning approximately 3,840 acres, the base has hosted the wing's headquarters and the majority of its operational units since the unit's activation there in 1946, following the establishment of Buckley Army Air Field in 1942.^[17]^[1] The base features specialized facilities tailored to the 140th Wing's fighter operations, including Hangar 909, which was renovated in 2015 to enhance maintenance and support capabilities for F-16 Fighting Falcon aircraft. Additional infrastructure encompasses operations centers such as the 140th Squadron Operations facility, aircraft maintenance hangars, and training simulators that enable mission rehearsals and pilot proficiency. These assets are shared with active-duty Space Force units, including Space Base Delta 2 and Space Delta 4, fostering integrated support for both air and space missions at the installation.^[37]^[38]^[39] Historically, the installation underwent several renamings that reflect its evolving missions: designated Buckley Field from 1942 to 1947, Naval Air Station Denver from 1947 to 1960, Buckley Air National Guard Base from 1960 to 2000, Buckley Air Force Base from 2000 to 2021, and finally Buckley Space Force Base on June 4, 2021, to emphasize the growing emphasis on space operations and missile warning capabilities.^[40]^[41]^[42] In its current role, Buckley Space Force Base underpins the 140th Wing's core functions, including 24/7 fighter alert commitments under Operation Noble Eagle to defend U.S. airspace, comprehensive aircraft maintenance by the 140th Aircraft Maintenance Squadron, and civil engineering support through the 140th Civil Engineer Squadron for base infrastructure and rapid response. The installation also plays a vital role in state emergencies, with wing personnel deploying for wildfire suppression and other disaster relief efforts as authorized by Colorado's governor.^[4]^[43]^[44]^[45]

Geographically Separated Units

The 140th Wing operates two geographically separated units (GSUs) outside its primary base at Buckley Space Force Base, enabling specialized missions in space operations and civil engineering while maintaining alignment with broader Air National Guard objectives.^[1] The 233rd Space Group serves as the wing's principal GSU for space missions, headquartered at Greeley Air National Guard Station in Greeley, Colorado, approximately 50 miles north of Buckley.^[5]^[46] Activated on March 10, 2013, the group comprises nearly 400 personnel, including dual-status technicians, Active Guard Reserve members, and traditional guardsmen, who deliver mobile, survivable space-based missile warning and attack characterization to the National Command Authority and joint forces.^[5]^[31] Its core components include the 137th Space Warning Squadron for missile detection and surveillance, the 233rd Space Communications Squadron for secure data relay, and support elements such as the 233rd Security Forces Squadron and 233rd Logistics Readiness Flight.^[5] The group evolved from the 137th Space Warning Squadron, the first Air National Guard unit to inherit an Air Force Space Command mission in January 1996, transitioning from active-duty oversight to state control.^[5] Until October 1, 2025, the 233rd Space Group encompassed the 138th Electromagnetic Warfare Squadron (formerly designated Space Control Squadron), a detached element at Peterson Space Force Base in Colorado Springs, about 70 miles south of Buckley, focused on space domain awareness, orbital analysis, and electromagnetic warfare training.^[1]^[47] Established in May 2019 as part of post-2020 expansions to bolster National Guard space contributions, the 138th employed around 100 personnel and supported realistic wartime simulations for space control.^[48] Following the transfer of select space missions to the U.S. Space Force under federal authority, the squadron's operations realigned, with its facilities and core functions shifting while most personnel remained in the Colorado Air National Guard for reassignment to emerging roles.^[49] The wing's second GSU, the 240th Civil Engineer Flight, consists of 40 specialized engineers providing expeditionary support across detachments in Colorado and deployed theaters.^[1]^[35] This unit excels in operational planning, facility design, construction management, and environmental compliance, deploying for disaster response and infrastructure projects, such as post-hurricane recovery in Puerto Rico.^[50] These GSUs report administratively to the 140th Wing for training and readiness but operationally align with U.S. Space Command for space-related tasks, enhancing national missile defense through integrated early warning and surveillance.^[5] The spatial separation—exceeding 100 miles when including former Colorado Springs elements—requires robust coordination via joint exercises, shared command posts, and digital networks to ensure seamless integration with Buckley-based operations.^[46] Recent post-2020 developments, including the 138th's activation and subsequent 2025 realignment, underscore ongoing adaptations to evolving space priorities while sustaining the wing's multi-domain contributions.^[47]^[49]

Equipment

Current Inventory

The 140th Wing maintains a fleet of more than 20 F-16C+ Fighting Falcon multi-role fighter aircraft, primarily operated by the 120th Fighter Squadron for air-to-air and air-to-ground missions. These aircraft are equipped with advanced targeting systems such as LITENING II and SNIPER pods, along with precision-guided munitions including GPS- and laser-guided weapons.^[43]^[1] Until October 2025, the wing's 233rd Space Group oversaw satellite ground stations, including the Mobile Ground System operated by the 137th Space Warning Squadron, which processed data from Defense Support Program satellites for global missile warning and attack assessment. This system provided survivable early warning capabilities integrated into broader missile defense architectures. These space missions were transferred to the United States Space Force on October 1, 2025.^[5]^[51]^[49] Support assets include civil engineering equipment utilized by the 140th Civil Engineer Squadron for infrastructure maintenance, such as heavy machinery and systems for runway repair and expeditionary airfield operations. The wing also coordinates aerial refueling support through associations with KC-135 Stratotanker units to extend mission range during training and operations.^[52] Recent upgrades to the F-16 fleet focus on avionics sustainment and software enhancements for improved precision weapon employment and system reliability, with innovations addressing aging airframe challenges; no major structural or capability overhauls have occurred since 2020 beyond ongoing maintenance programs.^[1]^[53]^[54]

Historical Evolution

The 140th Wing's historical equipment progression commenced shortly after its federal recognition in 1946, when the unit equipped with the North American P-51D Mustang (designated F-51D in Air Force service) as its primary fighter aircraft, emphasizing air defense and training missions through the late 1940s and early 1950s. This piston-engine fighter, a veteran of World War II, provided the wing with versatile capabilities for interception and ground attack until the advent of jet propulsion necessitated a transition.^[55] During the unit's activation for the Korean War in 1951, operations continued with the F-51D, but by 1953, the wing had fully adopted the Lockheed F-80C Shooting Star, marking its entry into the jet age and aligning with the demands of high-speed aerial combat and reconnaissance.^[11] In the early 1960s, amid escalating Cold War tensions, the wing shifted to dedicated interceptor roles with the North American F-86L Sabre, a radar-equipped variant of the Sabre family used from 1960 to 1961 to enhance all-weather air defense capabilities against potential Soviet bomber threats. This aircraft, an evolution from the earlier F-86E models used in demonstration teams like the "Minute Men," featured improved fire-control systems for rapid response intercepts.^[55] By the early 1960s, the wing transitioned to the supersonic North American F-100D Super Sabre, equipping squadrons for tactical fighter-bomber operations that included air-to-ground strikes and superiority missions, a role that saw deployment during the Pueblo Incident in 1968 and extensive combat support in Vietnam where the 120th Tactical Fighter Squadron logged over 6,000 sorties.^[11] The F-100D's versatility in both air defense and close air support defined the wing's contributions through the 1960s and into the 1970s. The 1970s ushered in a tactical focus with the adoption of the LTV A-7D Corsair II in 1974, replacing the F-100D and emphasizing precision attack and forward air control, particularly in post-Vietnam exercises that honed close air support tactics.^[55] The subsonic A-7D, with its advanced avionics for low-level bombing, enabled the wing to excel in competitions like the 1981 Gunsmoke air-to-ground gunnery meet, where it secured top honors as "World Champions."^[10] This era represented the wing's maturation as a dedicated tactical fighter outfit until the A-7D's retirement in 1992, prompted by the Air Force's shift toward multirole fighters amid post-Cold War force reductions. Since 1992, the wing has operated the General Dynamics/Lockheed Martin F-16C/D Fighting Falcon as its core aircraft, a highly adaptable multirole platform supporting air superiority, interdiction, and homeland defense missions without significant type changes to date.^[1] Complementing this aerial evolution, the 2000s saw the integration of space surveillance capabilities, including radar systems under the 233rd Space Group—originating from Cold War-era mobile ground terminals activated in the 1980s and transferred to the Colorado Air National Guard in 1992 for missile warning and satellite tracking. These non-kinetic assets expanded the wing's mission scope to space domain awareness, reflecting broader Air Force priorities in an era of dual-use fighter and surveillance operations, until the missions were transferred to the United States Space Force in October 2025.^[5]^[55]^[51]^[49]

Lineage and Honors

Formal Lineage

The 140th Wing traces its formal origins to the post-World War II reorganization of the Colorado Air National Guard, with its predecessor elements receiving federal recognition on 1 October 1946 as the 140th Fighter Group.^[12] The wing itself was constituted as the 140th Fighter Wing and allotted to the Colorado Air National Guard on 31 October 1950, before being organized and federally recognized on 1 November 1950.^[12] Key redesignations occurred as follows: to 140th Fighter-Bomber Wing on 12 April 1951, serving in that capacity until 1 July 1955; to 140th Fighter-Interceptor Wing on 1 July 1955, until 1 January 1961; to 140th Tactical Fighter Wing on 1 January 1961, until 15 March 1992; briefly to 140th Fighter Wing on 15 March 1992, until 1 July 1995; and finally to 140th Wing on 1 July 1995, a designation it retains to the present.^[12] An interim redesignation to 140th Air Defense Wing occurred on 1 July 1957, lasting until the 1961 change.^[12] Status changes included federalization and placement on active duty from 1 April 1951 to 15 November 1952, during which the unit was released from active duty and returned to state control; and again from 25 January 1968 to 30 April 1969, marking periods of extended federal service amid Cold War tensions.^[12] The wing has remained active since its 1950 activation, with no full inactivations, though subordinate elements were inactivated and reactivated during major conflicts such as World War II.^[12] A primary sub-unit, the 120th Fighter Squadron, carries a lineage dating to 27 June 1923, when it was constituted as the 120th Aero Observation Squadron in the Colorado Army National Guard, initially focused on observation roles with early aircraft like the Curtiss JN-4.^[11] It received federal recognition on 1 October 1946 as the 120th Fighter Squadron, aligning with the broader group's establishment.^[12]

Assignments, Stations, and Campaigns

The 140th Wing traces its higher command assignments to its activation as part of the Colorado Air National Guard in 1950, with federal recognition on 1 November 1950. Prior to full wing status, its predecessor elements, including the 140th Fighter Group formed in 1946, fell under Fourth Air Force from 1946 to 1951 for training and administrative oversight as part of the nascent Air National Guard structure. Upon federalization for the Korean War on 1 April 1951, the wing was assigned to Tactical Air Command, operating under this major command until its release to state control on 15 November 1952.^[12]^[11] From 1951 to 1992, the wing maintained primary alignment with Tactical Air Command during federal activations and training missions, reflecting its tactical fighter role. Concurrently, following its redesignation as the 140th Fighter-Interceptor Wing on 1 July 1955, it received a dual assignment to Air Defense Command from 1955 to 1961, supporting continental air defense operations with interceptor aircraft. This period overlapped with Tactical Air Command oversight for non-air defense missions. Since 1992, following the reorganization of major commands after the Cold War, the wing has been assigned to Air Combat Command, which provides its federal mission focus on fighter operations and expeditionary support.^[12]^[1] The wing's stations have remained predominantly in Colorado, with no permanent relocations outside the state. It was initially organized at Buckley Field, Colorado, on 1 November 1950, serving as its primary base until federalization. During the Korean War mobilization from 12 April 1951 to 1 January 1953, the wing temporarily relocated to Clovis Air Force Base, New Mexico (later Cannon AFB), for operational training and deployment support, before returning to Buckley Field (redesignated Buckley Air Force Base in 1960 and Buckley Space Force Base in 2023). The wing was federalized, with headquarters and support elements briefly stationed at Cannon AFB, New Mexico, from c. 1 May 1968 to 30 April 1969, while the 120th Tactical Fighter Squadron deployed operationally to Phan Rang Air Base, South Vietnam. The wing's permanent station has been Buckley since 1953, with geographically separated units at sites like Greeley Air National Guard Station and Peterson Space Force Base remaining within Colorado.^[12]^[1] The 140th Wing's campaign credits stem primarily from activations of its subordinate units, such as the 120th Fighter Squadron, rather than full wing deployments. During the Korean War from 1951 to 1952, the wing supported operations through federal service at Clovis AFB, providing trained pilots and resources to active-duty forces, though not directly deploying combat units overseas. In the Vietnam War, the 120th Tactical Fighter Squadron was federalized from 25 January 1968 to 30 April 1969, deploying F-100 Super Sabres to Phan Rang Air Base, South Vietnam, where it flew over 6,000 combat sorties in close air support and interdiction missions.^[12]^[1] For Armed Forces Expeditionary operations, the wing contributed through partial mobilizations during the Berlin Crisis in 1961 and the Cuban Missile Crisis in 1962, augmenting active-duty air defense with alert fighters and personnel from Buckley AFB. In Southwest Asia, elements supported Operation Desert Storm in 1991 via mobilization of security police and medical units, followed by rotations for Operation Southern Watch through the 1990s, enforcing no-fly zones over Iraq with F-16 patrols and logistics. The wing's involvement in the Global War on Terror includes continuous Operation Noble Eagle alerts since 11 September 2001, providing 24/7 fighter coverage over the central U.S.; deployments for Operation Enduring Freedom in Afghanistan, such as engineering support in 2005; and multiple rotations for Operation Iraqi Freedom from 2003 to 2009, including F-16 missions from Joint Base Balad and other bases.^[11]^[56]^[57]

Awards and Decorations

The 140th Wing has received the Air Force Outstanding Unit Award with the "V" device for valor during its Vietnam War deployment from 1968 to 1969, recognizing the unit's support in flying over 6,000 combat missions from Phan Rang Air Base. The wing earned additional Air Force Outstanding Unit Awards for exemplary performance in deployments, including a 1977 rotation to Gilze-Rijen Air Base in the Netherlands as part of a NATO exercise and for the period 1 October 2019 – 30 September 2021. These honors reflect the wing's contributions to air defense, combat operations, and international cooperation.^[58] Subordinate units have also garnered notable decorations. The 120th Fighter Squadron received the Republic of Vietnam Gallantry Cross with Palm for service from 1 April 1966 to 31 August 1971, acknowledging its role in close air support and reconnaissance missions during the Vietnam conflict. The 233rd Space Group, responsible for missile warning and space surveillance, has been awarded the Air Force Outstanding Unit Award for its operational excellence in providing critical early warning data to national command authorities. The wing's campaign streamers, displayed on its guidon alongside approximately 10–15 major unit decorations, include two for Korean Service reflecting its 1951 mobilization and air defense patrols during the Korean War; one for Vietnam Service tied to its 1968–1969 combat deployment; two for Southwest Asia Service for operations during Desert Storm and subsequent enforcement missions; and streamers for Global War on Terror–Service (Operation Noble Eagle) for homeland defense alerts post-9/11, as well as Global War on Terror–Expeditionary (Operation Enduring Freedom) for deployments to Afghanistan and related theaters from 2003 onward.
