Ellsworth Air Force Base

Ellsworth Air Force Base is a United States Air Force installation located in the Black Hills of South Dakota, approximately 10 miles east of Rapid City, serving as the home of the 28th Bomb Wing and one of only two bases worldwide operating the B-1B Lancer supersonic strategic bomber.^[1]^[2]
Originally established in 1942 as Rapid City Army Air Base to train heavy bombardment groups during World War II, the facility was redesignated Ellsworth Air Force Base in 1957 in honor of Brigadier General Richard E. Ellsworth, a pioneering aviator who commanded strategic reconnaissance operations and perished in a B-36 crash.^[3]^[4]
The base transitioned through various missions, including intercontinental ballistic missile operations with Titan I and Minuteman systems before focusing on strategic bombing following the arrival of its first B-1B Lancer on January 21, 1987, which enhanced its role in long-range conventional strike capabilities.^[5]^[1]
Under the Eighth Air Force and Air Force Global Strike Command, the 28th Bomb Wing—comprising about 3,700 Airmen and Department of Defense civilians—executes the core mission of on-demand global strike, maintaining a fleet of 27 B-1B Lancers for precision munitions delivery and supporting MQ-9 Reaper remotely piloted aircraft operations via tenant units like the 89th Attack Squadron.^[6]^[2]^[7]
Ellsworth's aircraft have conducted significant combat missions, including the B-1B's rapid deployment in Operation Odyssey Dawn in 2011 for strikes against Libyan forces, demonstrating the base's strategic value in projecting air power for deterrence and decisive response.^[8]^[9]

History

World War II Origins

The U.S. War Department established Rapid City Army Air Base on January 2, 1942, near Rapid City, South Dakota, as a dedicated training facility for heavy bomber crews during World War II.^[10]^[11] The base's primary mission was to prepare aircrews for the Boeing B-17 Flying Fortress, a four-engine heavy bomber critical to strategic bombing campaigns against Axis forces in Europe.^[12]^[13] Construction proceeded rapidly under the Second Air Force, with runways completed by late September 1942, enabling the base's first operational training flights and activation of its control tower.^[12]^[14] Training emphasized formation flying, navigation, bombing accuracy, and gunnery, drawing on the region's open plains and low population density to simulate combat conditions safely.^[3] By mid-1943, the base had trained multiple bombardment groups, contributing directly to the Eighth Air Force's buildup for sustained daylight raids over Germany.^[15] Its role underscored the U.S. Army Air Forces' emphasis on scalable pilot and crew production to achieve air superiority, with thousands of personnel cycling through the facility before deployment to overseas theaters.^[3]

Postwar Expansion and Early Strategic Role

Following the end of World War II, Rapid City Army Air Base was placed on standby status on July 15, 1945, amid the demobilization of Army Air Forces units, but rising Cold War tensions necessitated its prompt reactivation to support strategic air capabilities.^[12]^[13] The base reopened within approximately six months, transitioning from a training facility to a hub for heavy bombardment operations under the newly independent U.S. Air Force, established in September 1947. On March 23, 1947, the Army Air Forces activated the 28th Bombardment Group at the base, with formal assignment on May 3, 1947, equipping it with B-29 Superfortress bombers for long-range strategic missions.^[16]^[17] This marked the beginning of its integration into the Strategic Air Command (SAC), activated in March 1946 to maintain nuclear deterrence through bomber fleets capable of delivering atomic weapons globally.^[18] Infrastructure expansion accelerated in the late 1940s to accommodate larger aircraft and sustain SAC's operational tempo, including the construction of specialized hangars and support facilities. The 28th Bombardment Wing was established on July 28, 1947, and organized on August 15, 1947, as a "Very Heavy" bombardment unit, initially operating B-29s from 1947 to 1950.^[2]^[19] Runway improvements completed in July 1949 extended the pavement to over 12,000 feet, enabling the deployment of the massive Convair B-36 Peacemaker starting that year, which featured a 230-foot wingspan, six propeller engines supplemented by four jet pods, and intercontinental range for nuclear strikes without refueling.^[13]^[18] By 1950, reconnaissance variants (RB-36) supplemented the bomber fleet, enhancing SAC's intelligence and targeting capabilities amid escalating Soviet threats.^[18] These upgrades positioned the base as a critical node in SAC's dispersed alert posture, with aircraft maintained at high readiness for rapid deployment. The early strategic role emphasized deterrence through sustained airborne alerts and global reach, as the B-36 fleet at Rapid City—peaking with multiple squadrons—formed part of SAC's backbone for potential atomic retaliation against communist expansion. In April 1950, amid the Korean War outbreak, the base shifted from the 15th Air Force to the 8th Air Force under SAC, underscoring its prioritization for combat-ready heavy bombardment.^[20] This era saw the base's personnel and facilities expand significantly, with construction programs in the late 1940s and early 1950s adding administrative buildings, fuel storage, and crew quarters to support around 5,000 airmen and their families, reflecting the Air Force's shift toward permanent, hardened installations for prolonged nuclear standoff.^[21] The B-36's ability to carry the Mark 17 hydrogen bomb, introduced in the early 1950s, further cemented the base's role in evolving from conventional bombing to thermonuclear delivery, though operational challenges like engine reliability and maintenance demands highlighted the technological risks of early jet-augmented propulsion.^[20]

Cold War Bomber and Missile Integration

Ellsworth Air Force Base played a pivotal role in the U.S. Strategic Air Command's (SAC) efforts to integrate manned bombers with unmanned intercontinental ballistic missiles (ICBMs) during the early 1960s, enhancing the base's contribution to the nation's nuclear triad. The base had already established a strategic bomber presence with the arrival of the first Boeing B-52 Stratofortress aircraft in 1957, operated by the 28th Bombardment Wing, which conducted long-range missions capable of delivering thermonuclear weapons.^[22] This bomber force provided flexible, crewed strike options amid escalating Cold War tensions.^[10] To diversify its deterrent capabilities, Ellsworth integrated ICBM operations with the activation of the 44th Strategic Missile Wing on January 8, 1962, initially equipped with HGM-25A Titan I missiles. The 850th Strategic Missile Squadron, part of this wing, began preparations in 1961, with the first Titan I missile arriving on May 31, 1962, and all 18 missiles deployed across three launch complexes by June 1963.^[23] ^[18] These underground silos, located approximately 50 miles from the base, offered rapid-response, silo-launched nuclear strikes independent of aircraft vulnerability to enemy air defenses, complementing the B-52s' standoff capabilities.^[24] The coexistence of B-52 bombers and Titan I missiles from 1962 until the ICBMs' deactivation in 1965 represented a key phase of SAC's "aerospace" integration, where bases like Ellsworth maintained dual missions to ensure redundancy in second-strike potential.^[23] This integration demanded expanded infrastructure, including missile assembly and maintenance facilities at the base, while SAC protocols ensured coordinated alert postures for both systems to maximize survivability against Soviet preemptive attacks. The Titan I's liquid-fueled design required on-site fueling, contrasting with the B-52's aerial refueling endurance, thus necessitating specialized personnel and training to manage the hybrid forces.^[18] By blending these assets, Ellsworth bolstered SAC's doctrine of assured retaliation, deterring aggression through layered, multi-platform nuclear delivery options during a period of intense U.S.-Soviet rivalry.^[25]

ICBM Operations and Transition

The 44th Strategic Missile Wing was activated at Ellsworth Air Force Base on January 1, 1962, as part of the U.S. Air Force's expansion of its intercontinental ballistic missile (ICBM) forces under Strategic Air Command, initially equipped with nine SM-68 Titan I missiles operated by the 850th Strategic Missile Squadron.^[26]^[23] These liquid-fueled, first-generation ICBMs were deployed in hardened underground silos across western South Dakota, with the first operational missiles arriving on June 22, 1962, supported by three launch crews trained for rapid response in nuclear deterrence roles.^[23] The Titan I systems emphasized survivability against Soviet attacks through deep silos and quick-fueling capabilities, though their complexity limited operational tempo compared to emerging solid-fuel designs.^[27] Transition to solid-fueled LGM-30 Minuteman I missiles began in 1963, with the first Minuteman IB emplaced in a launch facility near Wall, South Dakota, in April, marking Ellsworth as one of the early bases to integrate this more reliable and maintainable ICBM.^[24] By the end of 1963, initial flights were operational, and the wing achieved full alert status with 150 Minuteman I missiles by October 1965, distributed across five squadrons (67th, 68th, 98th, 99th, and 319th Strategic Missile Squadrons), each managing 50 missiles in dispersed silos connected to five missile alert facilities per squadron.^[24]^[28] The Titan I squadron was deactivated in 1965 as Minuteman deployment completed, reflecting the Air Force's shift toward solid-propellant systems for reduced launch preparation time and higher readiness rates.^[29] Upgrades to LGM-30F Minuteman II missiles occurred between 1967 and 1969, enhancing payload capacity with multiple independently targetable reentry vehicles (MIRVs) and improved accuracy, while the wing maintained continuous 24-hour alert postures to ensure second-strike capability amid Cold War tensions.^[17]^[24] Operations involved rigorous maintenance, security protocols, and simulated launch exercises, with the 44th Missile Wing overseeing 150 silos spread over 13,000 square miles, contributing to national deterrence without recorded accidental launches over 32 years of service.^[30]^[27] The wing's ICBM mission ended with its inactivation on July 15, 1994, as part of post-Cold War force reductions under the Strategic Arms Reduction Treaty (START I), which mandated downloading and decommissioning Minuteman II missiles at Ellsworth while retaining them at other bases upgraded to Minuteman III.^[28]^[31] Deactivation involved explosive demolition of silos and alert facilities, environmental remediation, and transfer of missile assets, allowing the base to consolidate under the 28th Bomb Wing's conventional bomber operations with the B-1B Lancer, which had operated alongside ICBMs since 1987, thereby refocusing Ellsworth on air-delivered strategic strike capabilities.^[27]^[10] This transition aligned with broader U.S. nuclear posture shifts emphasizing bomber flexibility over fixed-site vulnerabilities in a reduced-threat environment.^[27]

B-1B Lancer Deployment and Modernization

The B-1B Lancer fleet arrived at Ellsworth Air Force Base in 1987, marking the base's transition to hosting supersonic strategic bombers under the 28th Bombardment Wing.^[2] The 37th Bomb Squadron was activated on January 1, 1987, to operate the aircraft, with the wing eventually maintaining up to 27 B-1Bs for global strike missions.^[2] These bombers enabled rapid deployment capabilities, supporting operations from the base through Bomber Task Force rotations that demonstrated long-range power projection. Key deployments from Ellsworth highlighted the B-1B's role in combat and deterrence. On March 27, 2011, B-1Bs from the 34th Bomb Squadron participated in Operation Odyssey Dawn, launching from the base for strikes in Libya, completing the first transcontinental combat mission for the aircraft type from Ellsworth.^[8] In October 2019, multiple B-1Bs deployed to Saudi Arabia under Bomber Task Force operations in U.S. Central Command, launching directly from Ellsworth to integrate with regional allies.^[32] More recently, in March 2025, the 34th Expeditionary Bomb Squadron deployed four B-1Bs with support personnel for Bomber Task Force 25-1, underscoring Ellsworth's contribution to agile combat employment amid great power competition.^[33] Modernization efforts focused on enhancing the B-1B's avionics and weapons integration to extend its service life. The Integrated Battle Station upgrade, initiated in 2012, was completed across the fleet by September 2020 at Ellsworth, replacing analog systems with color multifunction displays, improved navigation, and secure communications for better aircrew situational awareness.^[34] This eight-year project, finished ahead of schedule, integrated offensive and defensive management into a single station.^[35] Subsequent BEAST modifications, including new external pylons tested in 2025, aimed to expand missile carriage for external loads, though Ellsworth's fleet began relocating to Grand Forks AFB in December 2024 to facilitate B-21 Raider infrastructure.^[36]^[37] These upgrades sustained the B-1B's conventional bombing role until retirement, with Ellsworth maintainers mobilizing the full fleet for exercises as late as February 2025.^[38]

Post-Cold War Deployments and Operations

In 1999, five B-1B Lancers from the 28th Bomb Wing at Ellsworth Air Force Base participated in Operation Allied Force, a NATO air campaign against Yugoslav forces in Kosovo. The aircraft launched strikes on military targets beginning April 1, 1999, marking one of the early major combat deployments for Ellsworth's B-1 fleet post-Cold War.^[18]^[39] Following the September 11, 2001, terrorist attacks, the 28th Bomb Wing deployed B-1B aircraft and crews to Diego Garcia in the Indian Ocean to support Operation Enduring Freedom in Afghanistan. B-1s from Ellsworth contributed significantly to initial strike sorties, with the platform accounting for approximately 10% of early combat missions and delivering a substantial portion of munitions. The 28th Aerospace Expeditionary Wing oversaw operations that emphasized the B-1's loiter capability over battle areas.^[19]^[40] During Operation Iraqi Freedom in 2003, crews from the 34th and 37th Bomb Squadrons at Ellsworth flew numerous B-1B sorties against Iraqi targets, integrating conventional bombing with precision-guided munitions. The deployments highlighted the wing's role in coalition air campaigns, supporting ground forces with close air support and strategic strikes.^[41] In March 2011, two B-1B Lancers from the 28th Bomb Wing launched from Ellsworth on short notice—within 48 hours—to conduct strikes in Libya as part of Operation Odyssey Dawn, enforcing a UN-mandated no-fly zone. The aircraft completed a 21-hour non-stop mission, demonstrating rapid global reach and the base's readiness for expeditionary operations.^[8]^[42]

Recent Developments and Transitions

In 2021, the U.S. Air Force selected Ellsworth AFB as the first operational base for the B-21 Raider stealth bomber, initiating a multi-year transition from the B-1B Lancer fleet to enhance long-range strike capabilities. This decision positioned Ellsworth to host the initial squadron of B-21s, with the program aimed at replacing aging B-1Bs and B-2 Spirits incrementally by the mid-2020s.^[43] As of September 2024, the B-21 remains in flight testing, with the second test aircraft arriving at Edwards AFB on September 11, 2025, and infrastructure at Ellsworth advancing to support operational readiness expected around 2026.^[44] To facilitate the B-21 integration, the Air Force awarded contracts for specialized facilities, including a $33.5 million project for B-21 Environmental Protection Shelters initiated in July 2025 by Conti Federal Services.^[45] An additional $80 million contract in June 2024 funded a 80,000-square-foot phase maintenance hangar with associated apron and utilities.^[46] Runway reconstruction efforts, critical for B-21 operations, prompted deconstruction starting January 31, 2025, while the 28th Bomb Wing's B-1B fleet continued missions from alternate locations; a December 2024 drill simulated relocating up to 17 B-1Bs and 800 personnel to Grand Forks AFB, North Dakota.^[47] By December 2024, plans advanced to temporarily disperse the entire B-1B fleet from Ellsworth to accommodate B-21 runway modifications.^[48] The 28th Bomb Wing maintained operational tempo amid these transitions, supporting Bomber Task Force deployments such as BTF 25-1 in January 2025, with 34th Bomb Squadron B-1Bs launching from Ellsworth for global deterrence missions.^[49] Command leadership transitioned on July 25, 2025, when Col. Erick Lord assumed command from Col. John Watness, emphasizing readiness for the B-21 era amid ongoing B-1B sustainment challenges.^[50] Minor base incidents, including a September 12, 2025, lockdown due to reported shots nearby and wildlife management orders to mitigate airfield risks, underscored routine security and environmental adaptations.^[51]^[52]

Strategic Role and Operations

Global Strike and Deterrence Capabilities

Ellsworth Air Force Base serves as the primary operating location for the 28th Bomb Wing, which falls under Air Force Global Strike Command and executes missions central to U.S. strategic deterrence and global strike operations.^[53] The wing's B-1B Lancer bombers enable rapid, long-range projection of conventional firepower, supporting deterrence by demonstrating the ability to hold adversary targets at risk from intercontinental distances without forward basing.^[54] These capabilities include supersonic speeds exceeding Mach 1.2, a combat range of approximately 5,900 miles without refueling, and payload capacities up to 75,000 pounds of ordnance, allowing for multi-mission flexibility in contested environments.^[54] The 28th Bomb Wing routinely participates in Bomber Task Force deployments to underscore deterrence commitments, such as the August 2024 CONUS-to-CONUS mission by the 34th Bomb Squadron, which validated Ellsworth's readiness to generate and sustain combat sorties for adversary deterrence.^[55] In the Indo-Pacific, B-1B operations from Ellsworth, including forward deployments to Guam and Japan, have integrated with allies like Japan and the Republic of Korea, flying over 400 hours across 37 sorties with seven partner nations to enhance collective strike interoperability and regional assurance as of March 2025.^[56] These exercises emphasize visible, unpredictable bomber presence to deter aggression, with missions often involving aerial refueling to extend operational reach and simulate real-world global strike scenarios.^[57] Deterrence is further reinforced through Ellsworth's contributions to combat ammunition production exercises and weapons generation facilities, ensuring sustained sortie rates under wartime conditions; a July 2024 exercise highlighted the base's capacity to produce munitions rapidly for global operations.^[58] The B-1B fleet, numbering around 27 aircraft at Ellsworth as of recent assessments, supports non-nuclear strategic strike roles post-2011 nuclear divestment, focusing on conventional precision strikes to complement ICBM and stealth bomber assets in the broader AFGSC triad. Ongoing infrastructure upgrades, including a May 2024 groundbreaking for a new weapons facility, prepare the base for future B-21 Raider integration, which will enhance stealthy, penetrating strike capabilities to sustain deterrence amid great power competition.^[59] This transition maintains Ellsworth's pivotal role in executing AFGSC's mandate for anytime, anywhere combat support.^[58]

Contributions to Major Conflicts

The 28th Bomb Wing at Ellsworth Air Force Base has provided critical long-range strike capabilities in post-Cold War conflicts, primarily through deployments of the B-1B Lancer bomber operated by squadrons such as the 34th and 37th Bomb Squadrons. These operations emphasized precision bombing and suppression of enemy air defenses, supporting U.S. objectives in enforcing no-fly zones, degrading military infrastructure, and enabling ground forces.^[60] In December 1998, during Operation Desert Fox—a four-day campaign against Iraqi weapons facilities—B-1B Lancers from the 37th Bomb Squadron deployed from Ellsworth achieved the aircraft's combat debut. Four B-1Bs, staging from Sheikh Isa Air Base in Bahrain, released 188 Mk-82 500-pound bombs totaling 94,000 pounds on Iraqi targets, marking the first operational use of the bomber in combat despite facing anti-aircraft fire.^[61]^[62] Operation Allied Force in 1999 saw Ellsworth-based B-1Bs play a pivotal role in NATO's air campaign over Kosovo. Departing on April 1, 1999, the bombers flew more than 100 sorties, dropping over 1,260 tons of Mk-82 bombs on Serbian military positions, command centers, and infrastructure, which helped compel Yugoslav withdrawal and demonstrated the B-1B's ability to deliver massed conventional payloads rapidly.^[63]^[39] Following the September 11, 2001, attacks, the 28th Bomb Wing deployed B-1Bs to Diego Garcia in support of Operation Enduring Freedom in Afghanistan, operating as the 28th Air Expeditionary Wing to conduct strikes against Taliban and al-Qaeda targets. These missions involved extended sorties delivering joint direct attack munitions and other ordnance, contributing to the degradation of enemy command structures and safe havens.^[64]^[65] In Operation Iraqi Freedom starting in 2003, Ellsworth personnel and B-1Bs supported coalition efforts by deploying three aircraft and 403 airmen, focusing on close air support and strategic strikes that expended thousands of precision-guided munitions against Iraqi forces. The wing led Air Force contributions to the broader war on terror, including subsequent operations in Iraq where B-1s dropped 2,974 JDAMs, 1,471 Mk-82 bombs, 135 Mk-84 bombs, and 70 cluster munitions during deployments.^[18] Ellsworth B-1Bs also participated in Operation Odyssey Dawn in March 2011 to enforce a no-fly zone over Libya. On March 27, 2011, aircraft from the 34th Bomb Squadron launched amid blizzard conditions, destroying ammunition depots, combat aircraft, maintenance facilities, and air defense sites with over 100 2,000-pound joint direct attack munitions in strikes en route to and from Al Udeid Air Base in Qatar, showcasing rapid deployment and combat effectiveness.^[8]

Training and Readiness Exercises

The 28th Bomb Wing maintains operational readiness through a regimen of flight training, weapons systems proficiency, and simulated combat scenarios tailored to the B-1B Lancer's long-range strike role. Crews undergo regular sorties focusing on precision munitions delivery, electronic warfare countermeasures, and low-level penetration tactics, with annual flying hours exceeding 10,000 across the wing's squadrons. These foundational activities ensure rapid generation of combat airpower from Ellsworth's dispersed basing posture. Large-scale exercises like Red Flag at Nellis Air Force Base simulate high-intensity peer conflicts, integrating B-1B operations with joint and allied forces. During Red Flag-Nellis 23-3 from July 17 to August 4, 2023, the 28th Bomb Wing led Blue Force elements in contested environments, executing over 100 sorties amid 120-degree Fahrenheit conditions to validate tactics, techniques, and procedures.^[66] In Red Flag 24-3 from July 22 to August 2, 2024, wing aircrews conducted night operations, enhancing interoperability and survivability against advanced threats in a realistic training environment.^[67] Wing-specific drills such as Raider Reach in September 2024 evaluated end-to-end mission execution over two phases, including daily long-range B-1B flights, weapons loading under simulated austere conditions, and logistics sustainment for extended operations.^[68] This exercise stressed unit cohesion and rapid deployment capabilities, with maintainers preparing multiple Lancers for takeoff in support of global strike rehearsals.^[69] Readiness extends to ground support and base defense through exercises like the Combat Ammunition Production Exercise (CAPEX) from July 8 to 12, 2024, where munitions teams produced live ordnance to certify wartime surge capacity.^[58] Security Forces Squadron drills, including Cerberus Defender in July 2025, honed threat response across mission planning, convoy operations, and defensive perimeters.^[70] Bomber Task Force rotations, such as the January 2025 deployment, combine forward presence with live-fire training to deter adversaries and refine expeditionary skills.^[71]

Based Units and Personnel

28th Bomb Wing Structure

The 28th Bomb Wing (28 BW) is structured into four subordinate groups that collectively manage operations, maintenance, support services, and medical care for its approximately 3,800 personnel at Ellsworth Air Force Base.^[6] This organization aligns with standard U.S. Air Force wing frameworks under Air Force Global Strike Command, enabling the wing to execute its primary mission of strategic deterrence and global strike with B-1B Lancer bombers.^[2] The 28th Operations Group (28 OG) directs flying operations, including two B-1B combat-coded squadrons and support elements for mission planning and execution.^[41] The 28th Operations Group oversees the 34th Bomb Squadron ("Thunderbirds") and 37th Bomb Squadron ("Tigers"), which operate the wing's fleet of 27 B-1B Lancers for conventional bombing missions, alongside the 28th Operations Support Squadron responsible for airfield management, intelligence, weather, and tactics support. These bomb squadrons maintain combat readiness through training sorties and deployable expeditionary units, with the 34th BS historically leading in combat hours flown among B-1 units.^[2] The group ensures integration of aircrew training, weapons systems employment, and operational continuity, supporting global power projection under the Eighth Air Force.^[6] The 28th Maintenance Group provides aircraft sustainment, comprising the 28th Aircraft Maintenance Squadron for direct B-1B servicing and phase inspections, the 28th Maintenance Squadron for back-shop repairs and component overhaul, the 28th Munitions Squadron for ordnance loading and storage, and the 28th Maintenance Operations Squadron for quality assurance and engineering oversight.^[72] This group achieves high mission-capable rates for the aging B-1 fleet through specialized avionics, propulsion, and structural maintenance protocols. Complementing combat functions, the 28th Mission Support Group handles base infrastructure and logistics via squadrons including the 28th Civil Engineer Squadron for facilities and emergency response, 28th Communications Squadron for network and cyber operations, 28th Contracting Squadron for procurement, 28th Logistics Readiness Squadron for supply and deployment support, 28th Force Support Squadron for personnel services, and 28th Security Forces Squadron for law enforcement and defense.^[73] The 28th Medical Group, with its Medical Operations and Support Squadrons, delivers healthcare, occupational health, and aeromedical services to sustain aircrew and ground personnel fitness.^[6] Additionally, the 89th Attack Squadron operates as a tenant unit under Air Combat Command, conducting remotely piloted MQ-9 Reaper missions from Ellsworth since 2012.^[2]

Support and Specialized Squadrons

The 28th Maintenance Group oversees aircraft sustainment and support equipment for the wing's B-1B Lancer fleet, comprising approximately 1,500 personnel who maintain 27 bombers and enable global deployments.^[72] Its subordinate units include the 28th Aircraft Maintenance Squadron, responsible for direct aircraft servicing and flightline operations; the 28th Maintenance Squadron, which performs equipment repairs, engine maintenance, and weapons system inspections; the 28th Munitions Squadron, handling storage, assembly, and accountability of conventional munitions; and the 28th Maintenance Operations Squadron, which coordinates overall maintenance planning and quality assurance.^[72]^[74]^[75] The 28th Mission Support Group manages base infrastructure, logistics, and security, supporting over 3,800 facilities and 5,000 acres of land with a budget exceeding $40 million annually. Key squadrons under this group encompass the 28th Civil Engineer Squadron for facility construction, maintenance, and emergency response; the 28th Communications Squadron for network operations and cybersecurity; the 28th Contracting Squadron for procurement and vendor management; the 28th Logistics Readiness Squadron for supply chain, fuels distribution, and deployment readiness, including recognition as the Air Force's top fuels flight in recent competitions; the 28th Force Support Squadron for personnel services, family support, and morale programs serving active-duty, civilian, and retiree populations; and the 28th Security Forces Squadron for law enforcement, combat arms training, and base defense.^[73]^[6]^[76] The 28th Medical Group delivers healthcare and operational medicine, with the 28th Medical Operations Squadron conducting clinical services and flight medicine, and the 28th Medical Support Squadron providing ancillary support such as laboratory, pharmacy, and logistics functions.^[6]^[77] A specialized tenant unit, the 89th Attack Squadron—assigned to the 432nd Wing at Creech Air Force Base, Nevada—operates MQ-9 Reaper remotely piloted aircraft from Ellsworth since 2012, conducting intelligence, surveillance, reconnaissance, and strike missions in support of global operations.^[2]^[6]

Personnel and Command History

The personnel complement at Ellsworth Air Force Base has evolved with shifts in operational focus, from World War II-era training to Cold War nuclear deterrence and modern conventional strike missions. Established as Rapid City Army Air Base in January 1942, the installation initially supported B-17 Flying Fortress crew training under the 225th Army Air Forces Base Unit by early 1944, accommodating instructors and replacement aircrews amid rapid wartime expansion.^[12] ^[17] Reactivated in 1947 under Strategic Air Command, the base grew to host bombardment operations, with the 28th Bombardment Wing (redesignated Bomb Wing in 1963) relocating from Biggs Air Force Base, Texas, to Ellsworth on June 1, 1962, bringing B-52 Stratofortress squadrons and associated maintenance and support staff.^[19] During the Cold War peak, dual hosting of the 28th Bomb Wing's bombers and the 44th Strategic Missile Wing's Titan I (1962–1965) and later Minuteman II/III intercontinental ballistic missiles expanded the workforce to sustain alert postures and silo operations, though precise historical peaks remain undocumented in public records beyond general SAC-era growth patterns. Post-Cold War drawdowns following the 1991 Strategic Arms Reduction Treaty and 1994 missile wing inactivation reduced overall numbers, aligning with the 28th Bomb Wing's transition to B-1B Lancer operations under Air Combat Command in 1992 and subsequent realignment to Air Force Global Strike Command in 2009.^[64] Current strength includes approximately 3,100 active-duty Airmen focused on B-1B maintenance, operations, and support functions, plus 1,000 civilian employees handling logistics, security, and administration.^[78] Preparations for B-21 Raider integration anticipate growth to 3,500 military personnel by the mid-2020s to accommodate expanded squadrons and infrastructure demands.^[79] Command of the 28th Bomb Wing, the base's primary tenant, has passed through a lineage of colonels overseeing mission transitions from strategic bombing to global strike. Early wing commanders post-1947 reactivation included Col. Thomas J. Gent Jr. (August 1947) and Col. Raymond L. Curtice (September–October 1947), guiding initial SAC buildup.^[19] At Ellsworth since 1962, leadership has emphasized deterrence and expeditionary readiness, with notable post-Cold War figures such as Maj. Gen. Duncan J. McNabb (later four-star general) in interim roles and recent colonels including Gentry Boswell (2015–2017), Joseph L. Sheffield (circa 2021–2023), Derek C. Oakley (2023–2025), and Erick D. Lord, who assumed command on July 25, 2025, as the largest B-1B operator.^[80] ^[81] ^[82] ^[83] The wing reports to the 8th Air Force for operational control, with base command integrated under the wing staff, including a deputy commander and chief master sergeant.^[6]

Infrastructure and Facilities

Geographic and Climatic Advantages

Ellsworth Air Force Base occupies approximately 12,000 acres in western South Dakota, situated 10 miles northeast of Rapid City and adjacent to Box Elder, within the foothills of the Black Hills. This inland position in the continental United States provides strategic depth, distancing the base from coastal vulnerabilities and enabling rapid deployment of strategic bombers to either ocean theater for global strike missions. The surrounding terrain, characterized by open plains transitioning to rugged Badlands, supports secure operations with low population density—fewer than 10 people per square mile in Pennington County—minimizing risks to civilians during high-intensity training and reducing potential interference from commercial air traffic.^[84]^[85]^[86] Proximity to expansive military operating areas, such as the Powder River A and B Military Operations Areas encompassing over 55,000 square miles, allows for unrestricted low-altitude flight training and bombing practice essential for bomber wing proficiency, with minimal encroachment from urban development. The base's selection for advanced aircraft like the B-1B Lancer and forthcoming B-21 Raider underscores these geographic benefits, including sufficient open space for simultaneous mission execution and facility expansion without significant construction costs or mission disruptions. This configuration facilitates year-round readiness exercises, leveraging the isolated locale to simulate contested environments while maintaining operational security.^[87]^[88]^[89] The region's semi-arid climate, classified as cold semi-arid with average annual precipitation of 15-16 inches, yields over 220 days of sunshine annually, promoting high visibility for flight operations and reducing weather-induced delays compared to more humid or coastal bases. Low humidity levels—typically 40-60%—mitigate corrosion on aircraft airframes and equipment, extending maintenance intervals for high-value assets like strategic bombers. Although winters feature extreme cold, with temperatures dropping to -20°F or lower and wind chills exceeding -50°F, the predominantly clear skies and infrequent heavy snowfall (average 40 inches yearly) enable consistent operations, as evidenced by B-1B launches in blizzard conditions during combat support missions. These conditions, milder than more northern bases, balance challenges with advantages in visibility and dryness for sustained deterrence capabilities.^[90]^[85]^[91]

The airfield at Ellsworth Air Force Base consists of a single runway, designated 13/31, measuring 13,497 feet in length by 300 feet in width, with a concrete surface capable of supporting heavy bomber operations.^[92] The runway's pavement classification number is 73/R/C/W/T, accommodating aircraft such as the B-1B Lancer with high-intensity edge lighting for night and low-visibility conditions.^[92] Operations are managed by the 28th Operations Support Squadron under the 28th Operations Group, which oversees airfield management, radar approach control, and the control tower to ensure safe takeoffs and landings for strategic bomber missions.^[93] Support infrastructure includes specialized maintenance hangars and facilities tailored for B-1B sustainment, with the 28th Maintenance Group handling phase inspections, munitions loading, and aircraft servicing.^[1] Fuel storage and distribution systems support extended sorties, while apron areas facilitate bomber parking and ground equipment operations. Recent upgrades address B-21 Raider integration, including a new 73,000-square-foot two-bay phase maintenance hangar with associated apron expansions and utilities.^[94] In 2024, groundbreaking occurred for a dedicated weapons generation and maintenance facility to enhance security, safety, and capacity for current and future munitions handling.^[95] Additional enhancements include five B-21 environmental shelters equipped with ground support equipment, paving, and maintenance kiosks, contracted in July 2025 for $33.5 million to protect stealth bombers from weather and enable rapid deployment.^[45] These developments, funded in part by a $282 million allocation in the 2024 National Defense Authorization Act, also cover squadron operations facilities to sustain global strike readiness amid the transition from B-1B to B-21 fleets.^[96] Backup power infrastructure improvements, completed in 2024, provide grid resilience for airfield and adjacent civilian airport operations during outages.^[97]

Historical Missile Silos and Launch Facilities

Ellsworth Air Force Base entered the intercontinental ballistic missile (ICBM) era in October 1960 with the activation of the 850th Strategic Missile Squadron under the 28th Bombardment Wing, tasked with deploying HGM-25A Titan I missiles.^[10] The squadron received its first operational Titan I missile on June 22, 1962, and maintained nine silos organized into three launch complexes, each housing three missiles in hardened underground facilities designed for liquid-fueled, two-stage propulsion capable of delivering a 4-megaton warhead over 6,300 miles. These sites, located in remote prairie areas surrounding the base, emphasized survivability against Soviet strikes through deep burial and blast doors, though the Titan I's cryogenic fuels required complex handling and limited alert times compared to solid-fuel alternatives.^[23] The Titan I deployment proved short-lived due to technological obsolescence and maintenance challenges; the missiles were removed from alert status on January 4, 1965, with the squadron deactivating on March 25, 1965, as the Air Force shifted to more reliable solid-propellant systems.^[26] Concurrently, the 44th Strategic Missile Wing was activated at Ellsworth on January 1, 1962, initially incorporating the Titan I assets before transitioning to LGM-30 Minuteman missiles, reflecting Strategic Air Command's emphasis on rapid-response, silo-based deterrence. By 1963, the wing fully operationalized 150 Minuteman I silos divided among three squadrons—the 66th, 67th, and 68th Strategic Missile Squadrons—each controlling 50 missiles and five launch control facilities, with sites dispersed across western South Dakota prairies for redundancy and targeting flexibility.^[27] Construction of these hardened, 80-foot-deep silos began in 1961, featuring automated launch capabilities and single-warhead Mark 12 reentry vehicles initially, later upgraded to Minuteman II in the late 1960s with multiple independently targetable reentry vehicles (MIRVs) under the Mark 12A for enhanced penetration against defenses.^[24] The infrastructure included underground launch control centers manned by two-officer crews, supported by extensive security perimeters and communication links to ensure continuous alert status amid Cold War tensions.^[2] The Minuteman force at Ellsworth contributed to the U.S. nuclear triad until strategic arms reductions; the wing's missiles were deactivated between 1994 and 1996 under START I treaty implementation, with silos imploded or sealed to prevent reuse, though one 66th Squadron site near Wall, South Dakota, was preserved as the Minuteman Missile National Historic Site to document the era's deterrence posture.^[98] Decommissioning involved removing warheads and boosters by 1994, followed by environmental assessments revealing propellant residues, but the facilities underscored Ellsworth's role in maintaining 24/7 launch readiness for over three decades.^[99]

Environmental Management

Sources of Contamination

The principal sources of contamination at Ellsworth Air Force Base arise from decades of aviation and missile operations, including the use of aqueous film-forming foam (AFFF) containing per- and polyfluoroalkyl substances (PFAS) for firefighting training, aircraft crash response, and fuel fire suppression exercises conducted primarily at fire training pits and runways. PFAS, such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), were detected in base groundwater as early as 2011, with concentrations reaching up to 551,000 parts per trillion in soil and groundwater samples by 2016; the U.S. Air Force ceased use of PFAS-based foams at the base that year following initial well sampling.^[100]^[101]^[102] Volatile organic compounds (VOCs), including trichloroethylene (TCE) and tetrachloroethylene (PCE), stem from historical aircraft degreasing, paint stripping, and metal cleaning in maintenance hangars and workshops, as well as leaks from underground storage tanks and spills during fuel handling for B-52 and B-1 operations since the 1950s. These solvents migrated into soil and aquifers at Installation Restoration Program (IRP) sites, such as former landfills (e.g., Landfill 2) and industrial areas, contributing to groundwater plumes under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) oversight.^[103]^[104] Petroleum hydrocarbons and metals like arsenic and chromium have originated from fuel storage depots, wastewater treatment, and erosion-related discharges, with elevated levels noted in base drinking water supplies monitored under the Safe Drinking Water Act; arsenic detections exceeded Environmental Working Group health guidelines by factors up to 563 times in some samples. Former Minuteman missile silos and launch facilities of the 44th Missile Wing, operational from 1962 to 1996, introduced potential polychlorinated biphenyls (PCBs) from electrical transformers and maintenance solvents, alongside trace rocket propellant residues, though Air Force-wide assessments indicate these posed lower mobility risks compared to liquid fuels at liquid-fueled sites.^[105]^[106]

Detection, Extent, and Regulatory Response

Groundwater contamination at Ellsworth Air Force Base, primarily with trichloroethene (TCE) from past maintenance activities on aircraft and missiles, was first detected in the mid-1980s through routine monitoring wells installed as part of initial environmental assessments.^[107] This solvent, used in degreasing operations, migrated into the underlying Madison aquifer, which serves as a regional drinking water source, prompting further delineation studies that revealed plumes extending both on-base and off-base to the north and east.^[108] Per- and polyfluoroalkyl substances (PFAS), originating from aqueous film-forming foam (AFFF) used in firefighting training and incidents since the 1970s, were identified in subsequent investigations starting in 2016, with sampling of base production wells and groundwater monitoring points confirming exceedances of the U.S. Environmental Protection Agency's (EPA) Lifetime Health Advisory (LHA) of 70 parts per trillion (ppt) for PFOA and PFOS combined.^[109] ^[100] The extent of contamination spans multiple operable units (OUs) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), including soil and sediment impacts at former fire training areas, landfills, and spill sites, with groundwater plumes affecting approximately 10 square miles on-base and extending off-base to impact private wells in Box Elder and Rapid City areas.^[108] ^[110] PFAS concentrations in some monitoring wells reached over 4,600 ppt, far exceeding health advisories, while TCE plumes have been delineated to depths of over 500 feet in the aquifer, with dissolved-phase migration controlled by natural attenuation and groundwater flow toward the Cheyenne River.^[100] ^[111] Site inspections conducted in 2018 across 12 locations confirmed PFAS in soil and groundwater at fire protection training pits and crash response sites, leading to expanded plume mapping.^[110] Regulatory response began with the base's listing on the EPA's National Priorities List (NPL) as a Superfund site in 1989, triggering a Federal Facility Agreement between the Department of the Air Force, EPA Region 8, and the South Dakota Department of Agriculture and Natural Resources (SDDENR) to oversee investigation and remediation.^[100] ^[108] The EPA approved partial deletions from the NPL for remediated areas, such as Operable Unit 1 (former fire protection training area) in 2012, after confirming no further risk following soil removal and groundwater monitoring.^[112] For off-base impacts, the Air Force has provided alternate water supplies via an extension of the base's waterline since the 1990s to affected residents, with ongoing CERCLA five-year reviews ensuring remedy protectiveness.^[113] PFAS-specific actions include installation treatment systems and continued sampling under DoD-wide initiatives, aligned with EPA's 2024 maximum contaminant levels (MCLs) for six PFAS compounds, though full delineation remains incomplete as of 2024.^[100]^[107]

Remediation Efforts and Ongoing Monitoring

Remediation at Ellsworth Air Force Base has proceeded under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) since the site's listing on the National Priorities List in 1989, with the U.S. Air Force leading efforts under oversight from the Environmental Protection Agency (EPA) Region 8 and the South Dakota Department of Agriculture and Natural Resources. For the 12 operable units (OUs) addressing historical contamination from jet fuels, solvents like trichloroethylene (TCE), and waste disposal, remedies included soil excavation and off-site disposal, pump-and-treat systems for groundwater (with upgrades to the system in 2007 for efficiency), chemical oxidation and microbial bioremediation for in-situ treatment, landfill capping, and institutional controls such as land-use restrictions. Portions of the site, including OU-1 (former Fire Protection Training Area) and specific study areas like Gateway Lake Ash and Pride Hangar, achieved partial deletion from the NPL in 2006 and 2012 after remedial investigations confirmed cleanup goals met no unacceptable human health or ecological risks, with surface water, sediment, and above-ground soils verified as protective.^[100]^[112]^[114] Ongoing remediation focuses primarily on OU-13, the base-wide groundwater plume contaminated with per- and polyfluoroalkyl substances (PFAS) from aqueous film-forming foam used in firefighting training and emergencies, extending approximately 25 miles off-base. Since PFAS detection through Department of Defense-wide sampling beginning in 2016, the Air Force has implemented interim measures including PFAS removal actions starting in 2019, installation of point-of-use treatment systems for 21 impacted residential wells, provision of bottled water to three off-base properties exceeding EPA health advisory levels, construction of new community water lines (with progress updates noting advancements in waterline builds as of January 2025), and well replacements or abandonments. A remedial investigation for PFAS, initiated to delineate the plume and evaluate feasibility studies, included a second round of sampling from October 2024 to February 2025 in the eastern off-base area, alongside decommissioning of non-PFAS treatment infrastructure like extraction wells in 2024. Innovative approaches, such as in-situ remediation technologies including bentonite clay mats to contain and treat PFAS while minimizing excavation and carbon footprint, have been demonstrated at the site as part of green remediation practices.^[100]^[115]^[116]^[117] Monitoring and long-term management involve quarterly groundwater sampling by the Air Force and EPA oversight, with five-year reviews (most recent in 2015) confirming that implemented remedies remain protective of human health and the environment, though the next review will assess emerging PFAS data and new investigation areas like vapor intrusion from TCE and radioactive waste in concrete structures. The base maintains an Information Repository for public access to remedy selection documents and operates a Restoration Advisory Board (RAB) to facilitate community involvement in decision-making, including updates on PFAS progress and water infrastructure. Operations and maintenance continue for remaining groundwater treatment, with regulatory emphasis on aligning with EPA's 2024 PFAS drinking water standards (4 ppt for PFOA/PFOS), amid broader Department of Defense commitments to phase out PFAS-containing foams by October 2024.^[100]^[118]^[119]

Economic and Community Impacts

Local Demographic and Economic Contributions

Ellsworth Air Force Base serves as the largest single employer in the Rapid City region, directly employing approximately 4,100 personnel, including 3,100 active-duty airmen and 1,000 civilians, while supporting an additional 4,100 indirect jobs through supply chains and local services.^[78]^[78] In fiscal year 2023, the base generated $247.5 million in payroll, contributing to a total annual economic impact of $886.8 million in western South Dakota, encompassing spending on housing, retail, and construction that sustains local businesses and infrastructure.^[78]^[78] This footprint includes $526 million in state-wide contracts awarded by the Department of Defense, with a significant portion benefiting Rapid City-area vendors for maintenance and logistics.^[120] Demographically, the base influences the surrounding Pennington County area by housing about 3,000 on-base residents in ZIP code 57706, characterized by a young median age of 21.6 years and a population density shaped by transient military families.^[121] It supports 3,300 active-duty members, 3,500 dependents, 1,000 civilians, and over 8,100 retirees, injecting diversity into a region otherwise dominated by non-Hispanic white residents: on-base demographics show 11.9% Hispanic, 9.2% Black, 4.0% Asian, and 2.6% Native American populations, higher than South Dakota's statewide averages.^[85]^[122] This influx fosters a more cosmopolitan local profile, with 59.7% male residents reflecting military gender imbalances, and promotes population stability in Box Elder and Rapid City, where base-related growth has driven housing demand and school enrollments since the post-World War II era.^[123]^[79] Overall, these contributions mitigate rural depopulation trends, with the base acting as an economic anchor that correlates with sustained employment rates above state medians in defense-adjacent sectors.^[78]

Education, Housing, and Community Services

Education for military dependents at Ellsworth Air Force Base primarily relies on local public schools in the Rapid City area, as there is no on-base Department of Defense Education Activity school. The School Liaison Officer program assists families with school transitions, enrollment, and educational matters for school-aged children.^[124] Higher education opportunities include reduced tuition rates at Black Hills State University for active-duty personnel, Department of Defense civilians stationed at the base, and their dependents.^[125] South Dakota state law provides a 100% tuition waiver for children of military members who are state residents and under 25 years old, applicable to public universities.^[126] Military family housing at Ellsworth AFB is privatized and managed by Balfour Beatty Communities, offering three- and four-bedroom homes in neighborhoods such as Rushmore Heights and Prairie View Estates.^[127] The base includes 283 government-owned family housing units, with leasing support available through the Military Housing Office at (605) 385-2570.^[128] Off-base housing options are common in nearby areas like Box Elder and Rapid City neighborhoods, including North Hill, South Hill, and Rapid Valley.^[129] Community services are coordinated through the 28th Force Support Squadron, encompassing the Military and Family Readiness Center for deployment preparation, financial counseling, and personal readiness programs.^[130] Childcare options include the McRaven Child Development Center, operating Monday through Friday from 6:15 a.m. to 5:30 p.m., and the Family Child Care program, which serves children from 2 weeks to 12 years old, including those with special needs, via certified in-home providers.^[131]^[132] Morale, Welfare, and Recreation (MWR) programs provide fitness centers, sports, outdoor recreation activities like hiking and camping in the Black Hills, and travel services to support active-duty members, civilians, retirees, and families.^[76]^[133] Family support extends to advocacy programs offering parenting classes, couples communication, and support groups through the 28th Medical Group.^[134]

Relations with Nearby Installations and Civilian Areas

Ellsworth Air Force Base, situated approximately 10 miles east of Rapid City, South Dakota, and adjacent to Box Elder, maintains close operational and social ties with surrounding civilian communities in the Black Hills region.^[135] The base's proximity facilitates daily interactions, with over 9,500 military personnel, civilians, and families contributing to local commerce, housing, and services in Rapid City (population around 74,000 as of 2020 Census data integrated in regional reports) and nearby towns.^[135] ^[78] Community engagement initiatives by the 28th Bomb Wing emphasize building public trust through volunteerism and collaborative events. For instance, in September 2023, Ellsworth airmen participated in community service projects across Rapid City, including cleanup and support activities, to foster goodwill and integrate base personnel into local life.^[136] ^[137] The base operates a dedicated community partnerships portal connecting military families with Black Hills businesses, events, and resources, enhancing economic reciprocity and morale.^[138] Formal structures reinforce these relations, such as the South Dakota Ellsworth Development Authority, established to advocate for the base's sustainability and coordinate with state and local governments on hosting Department of Defense activities.^[139] The Military Advisory Coalition links over 4,000 military members from Ellsworth and the South Dakota National Guard to community stakeholders, promoting joint initiatives in areas like workforce development and emergency response.^[140] In 2025, programs expanded to include law enforcement exchanges, with Rapid City police liaisons embedded at the base to improve coordination on security and public safety matters.^[141] Innovation partnerships extend civilian-military collaboration, exemplified by a 2020s initiative between Ellsworth, the National Security Innovation Network, and the South Dakota School of Mines and Technology, focusing on technology prototyping and training solutions for defense needs.^[142] These efforts underscore a symbiotic relationship, where the base's $886.8 million annual economic impact bolsters civilian infrastructure while local support has historically shielded Ellsworth from closure threats, as in the 2005 Base Realignment and Closure process.^[78] ^[143] Regarding nearby military installations, Ellsworth stands as South Dakota's sole active-duty Air Force base, with the closest major facilities being F. E. Warren Air Force Base in Wyoming (approximately 250 miles southeast, hosting ICBMs) and Minot Air Force Base in North Dakota (about 300 miles north, with bombers and ICBMs).^[144] Inter-base relations primarily occur through Air Force Global Strike Command oversight for strategic bomber and missile operations, though no routine joint facilities or localized interactions are documented due to geographic separation. Coordination with South Dakota National Guard units supplements regional defense without direct installation adjacency.^[140]
