The 90th Missile Wing is a component of Twentieth Air Force, stationed at Francis E. Warren Air Force Base and equipped with LGM-30G Minuteman III Missiles. It has served at Warren as a component of Strategic Air Command, Air Combat Command, Air Force Space Command and Air Force Global Strike Command since 1963.


The wing was first organized at Fairchild Air Force Base, Washington as the 90th Bombardment Wing, a Boeing B-29 Superfortress unit. After moving to Forbes Air Force Base, Kansas, it served as a training unit for Strategic Air Command units and aircrews in the B-29. In 1953 it converted to the strategic reconnaissance mission, upgrading to the Boeing RB-47 Stratojet in 1954. After 1958 it trained reconnaissance crews with the B-47 and continued that mission until it was inactivated in 1960.


The wing operates 150 LGM-30G Minuteman III intercontinental ballistic missiles on full alert 24 hours a day, 365 days a year. It missiles are dispersed in hardened silos to protect against attack and connected to underground missile alert facilities through a system of hardened cables.


The 90th Missile Wing is made up of a wing staff and five groups:

The 90th Operations Group is composed of three missile squadrons, an operations support squadron and a standardization and evaluation element. Each missile squadron is responsible for five missile alert facilities and 50 Minuteman III ICBMs. Its units include the 319th, 320th and 321st Missile Squadrons and the 90th Operations Support Squadron.

The 90th Maintenance Group maintains 150 missiles and associated launch facilities, as well as 15 launch control facilities spread between a three-state, 9,600 square-mile complex. It is composed of the 90th Missile Maintenance Squadron and the 90th Maintenance Operations Squadron and a Maintenance Quality Assurance Section.

The 90th Mission Support Group provides civil engineering, transportation and logistics, communications, contracting, and personnel and services support to the wing and tenant units. The units of the 90th Mission Support Group include the 90th Civil Engineer Squadron, 90th Logistics Readiness Squadron, 90th Communications Squadron, 90th Contracting Squadron, and the 90th Force Support Squadron.

The 90th Security Forces Group is composed of five squadrons. The 790th Missile Security Forces Squadron provides security for convoys and missile maintenance operations. The 90th Ground Combat Training Squadron is located at Camp Guernsey in Guernsey, Wyo., and provides security, pre-deployment, and antiterrorism and force protection training for USAF personnel. The 90th Missile Security Forces Squadron provides security for 15 missile alert facilities and 150 launch facilities. The 90th Security Forces Squadron provides installation and weapons storage area security; police services; pass and registration functions; and reports and analysis duties. The 90th Security Support Squadron provides command and control for the missile field and access control for all missile field forces as well as all security forces training and equipment support.

The 90th Medical Group is responsible for medical and dental care for more than 17,000 beneficiaries throughout Wyoming, Nebraska and northern Colorado. The group's mission is to maximize personnel health, fitness and readiness through emphasizing health promotion and preventive medicine. The units of the 90th Medical Group include the 90th Medical Operations Squadron and the 90th Medical Support Squadron.

Superfortress operations

The wing was first organized at Fairchild Air Force Base, Washington in January 1951 as the 90th Bombardment Wing and equipped with the Boeing B-29 Superfortress. While organizing, it was attached to the 92d Bombardment Wing, whose commander also served as the commander of the 90th Wing. In February, as part of a reorganization of Strategic Air Command wings, the 90th Wing's 90th Bombardment Group was reduced to paper status and its squadrons were attached to the wing for operational control. In June 1952, this organization, which was designed to permit the wing commander to focus on the wing's combat units and the maintenance necessary to support combat aircraft, was formalized as the Dual Deputy Organization and the group was inactivated and its squadrons were assigned to the wing.

In March 1951, the wing moved to Forbes Air Force Base, where it served primarily as a training unit. In May, it began serving as an Operational Training Unit for B-29 aircrews and mechanics of newly-activating units. The 376th Bombardment Wing was the first new Superfortress wing trained by the 90th, activating on 1 June 1951. In October, it was combat ready and moved to Barksdale Air Force Base, Louisiana, its permanent base. The day the 376th Wing departed, the 308th Bombardment Wing was activated and began its training, which lasted until it moved to Hunter Air Force Base, Georgia in April 1952. The 310th Bombardment Wing was the last B-29 unit trained at Forbes. With its departure for Schilling Air Force Base, Kansas in September 1952, the B-29 operational training mission ended.

In June, the wing added duty as a Replacement Training Unit, primarily providing individual training for aircrew being assigned to existing Far East Air Forces B-29 units during the Korean War. In November 1952 it also began training replacement crews for the RB-29 reconnaissance model of the Superfortress and SHORAN personnel for Strategic Air Command (SAC). These training activities continued through November 1953.

Strategic reconnaissance

The wing began to fly strategic reconnaissance missions in September 1953. The following year, it replaced its RB-29s with the jet Boeing RB-47 Stratojet, with the first B-47E arriving on 25 June, although crews had begun training in March. One year later, the wing deployed as a unit to Eielson Air Force Base, Alaska from 5 May until 31 August 1955, where it performed the final mapping of Alaska. With the assignment of the 90th Air Refueling Squadron in 1955, the wing began to fly air refueling missions as well as reconnaissance flights. In May 1958, the wing returned to the training mission serving as a combat crew training wing for RB-47 aircrews until it was inactivated on 20 June 1960. The wing's personnel and equipment were transferred to the 40th Bombardment Wing, which moved to Forbes on paper from Schilling Air Force Base, Kansas the same day. The 90th Air Refueling Squadron was reassigned to the 40th Wing upon that wing's arrival at Forbes.

Strategic missiles

The wing was again organized in July 1963 at Francis E. Warren Air Force Base, Wyoming as the 90th Strategic Missile Wing. The LGM-30B Minuteman I missiles of the wing would replace the SM-65 Atlas missiles of the inactivating 389th Strategic Missile Wing. The replacement Minutemen would be more widely displaced and hardened than the Atlases they replaced.

Initially, the wing supervised missile facility construction until July 1964, with its individual squadrons activating between October 1963 and July 1964 as missile launch facilities became operational. The wing was initially equipped with 200 LGM-30B Minuteman I, equipped with a single reentry vehicle. Beginning in June 1973, the Minuteman I missiles began to be replaced by LGM-30G Minuteman IIIs, which could carry up to three reentry vehicles, with the 400th Strategic Missile Squadron becoming the first Minuteman III squadron in the wing. The changeout was completed by October 1974. However, in 2001 and in compliance with the Strategic Arms Reduction Treaty, these missiles were limited to a single reentry vehicle

The wing supervised LGM-118 Peacekeeper personnel training and facility preparation beginning Jun 1985. The Peacekeeper, which could carry ten independently targeted reetry vehicles, was fully operational with the wing's 400th Strategic Missile Squadron on 30 December 1986. The Peacekeeper system continued in operation in addition to the wing's Minuteman missiles until September 2005, when it was retired and the 400th Squadron inactivated.

Although it remained a component of Twentieth Air Force, starting in 1992, the wing saw a series of changes in the major command it was art of. When SAC was inactivated on 1 June 1992, the wing, along with its other combat missile units, became part of Air Combat Command. On 1 July 1993, after being redesignated as the 90th Space Wing, and with the idea to take advantage of the similarities between the missile and other space missions, the wing became part of Air Force Space Command. On 1 December 2009, the wing and other missile wings were reunited with the global bomber force under Air Force Global Strike Command.
