== [[World War II]] == 
On 2 Jan 1942, the U.S. War Department established Rapid City Army Air Base to train B-17 Flying Fortress heavy bomber units to fight the Axis in Europe. The control tower opened on 30 Sep 1942; runways, quarters, offices, and facilities were complete on 1 Oct 1942, and five hangars were completed in late 1942. The airfield had three concrete runways. Rapid City AAF was assigned to the 17th Bombardment Training Wing, II Bomber Command. The 88th Bombardment Group was reassigned to the new base in October 1942 to be the base's Operational Training Unit.

In March 1944, the base switched from training entire units to training replacement personnel to send to units already overseas. The field's instructors taught thousands of pilots, navigators, radio operators and gunners from nine heavy bombardment groups and numerous smaller units. On 15 July 1945, the training unit was deactivated and Rapid City AAB was placed on standby status.

Rapid City AAB was reactivated on 11 October 1945 and was assigned to Continental Air Force. It was designated a permanent facility by the Army Air Force. The base briefly trained weather reconnaissance and combat squadrons using P-61 Black Widow, P-38 Lightning, P-51 Mustang, and B-25 Mitchell aircraft.

From September 1946 to March 1947, the airfield was shut down for major improvements to accommodate the B-29 Superfortress. An extension to the runway was completed in spring 1948.

== [[Cold War]] ==
Operations resumed in 1947 with Rapid City AAF flying prop-driven B-29 bombers. In September 1947 a separate U.S. Air Force was created and bases assigned to the new Air Force became known as Air Force Bases. Rapid City AAF subsequently became Rapid City Air Force Base.

More runway improvements were completed in July 1949, allowing a switch from B-29s to the huge B-36 Peacemaker bombers. In 1953 Rapid City AFB became Ellsworth AFB. The B-36 bombers at Ellsworth AFB were phased out in 1957 for the new all-jet B-52 bombers. The last B-36 left Ellsworth on 29 May 1957 and the first B-52 arrived sixteen days later. 

In 1986, Ellsworth began to transition from the B-52 to the advanced B-1B Lancer bomber. New enlisted dormitories were completed in March 1986. A new security police squadron headquarters was completed in October, and Ellsworth's 13,497-foot runway was upgraded. The last of the B-52Hs left in early 1986 and in January 1987 the first of 35 B-1B bombers arrived.

== Post Cold War ==
On 1 Jun 1992, as part of the first major reorganization since the creation of USAF, the Air Force inactivated Strategic Air Command and assigned Ellsworth AFB to the newly activated Air Combat Command (ACC). The mission then changed from strategic bombardment to worldwide conventional munitions delivery with the B-1B bomber as the primary delivery vehicle.

===Air Defense ===
Air Defense Command (ADC) activated the 740th Aircraft Control and Warning Squadron (AC&W) at Rapid City AFB on 1 Feb 1953. See a separate page for the [[Ellsworth Air Force Station]]. This site was one of the Air Force radar sites designated to be co-located with a U.S. Army Nike Army Air-Defense Command Post (AADCP). ADC deactivated the Ellsworth radar site on 15 Aug 1962.

=== U.S. Army Nike Missiles Batteries ===
[[File:Nike Ajax Air Museum.jpg|thumb|right|250px|Nike Ajax Missile at the Air & Space Museum.]]
To provide air defense of the base, the United States Army established the Ellsworth AFB Defense Area in 1957 and constructed Nike-Ajax Surface-to-air missile sites. See a separate page for the [[:Category:Ellsworth NIKE Sites|Ellsworth NIKE Sites]]

Headquarters facilities were located at Ellsworth. In 1958, batteries E-20, E-40, and E-70 were removed from service and E-01 was converted to fire Nike Hercules missiles. This battery remained in service until 1961.

An Army Air-Defense Command Post (AADCP) was established at Ellsworth in 1960 for Nike missile command-and-control functions. The site was equipped with the GSG-5(V) BIRDIE solid-state computer system. The AADCP was integrated with the ADC Radar Site facilities. The AADCP ceased all operations when the ADC radar site shut down in 1962.

After the Army closed their facilities, the military housing at the Nike sites was transferred to control of Ellsworth AFB and was used as Air Force military family housing until about 1990.

== Strategic Missile Systems ==
=== EC-135 Airborne Launch Control Center 1970-1992 ===
From 1 Apr 1970 to 30 Sep 1992, the 4th Airborne Command and Control Squadron (ACCS) provided airborne command post capabilities with modified Boeing EC-135 airborne command post aircraft for the Strategic Air Command. The 4th ACCS was the workhorse of the Airborne Launch Control System (ALCS) operations. Three dedicated Airborne Launch Control Centers (ALCC), ALCC No. 1, ALCC No. 2, and ALCC No. 3 were on ground alert around-the-clock providing ALCS coverage for five of the six Minuteman Intercontinental Ballistic Missile (ICBM) Wings. 

====HGM-25A Titan I Missile, 1960-1965====
In October 1960, Ellsworth activated the 850th Strategic Missile Squadron in preparation for the arrival of [[HGM-25A Titan I]] intercontinental ballistic missiles (ICBM), which arrived in 1962, shortly after the activation of the 44th Strategic Missile Wing (44 SMW) in January.

The Titan ICBMs of the 850th SMS were removed from alert status on 4 Jan 1965 and the 850th SMS was deactivated on 25 Mar 1965.

====LGM-30 Minuteman Missile, 1962-1994====

[[File:Delta 09 Site - Practice Missile.jpeg|thumb|left|250px|Delta 09 Launch Site - Practice Missile in Silo on Display.]]
In July 1962, SAC activated the 66th Missile Squadron, the first of three such units slated to operate 150 [[LGM-30B Minuteman I]] ICBMs under the 44th Strategic Missile Wing (SMW). The 67th Missile Squadron joined the 44th in August, followed by the 68th Missile Squadron in September 1962.

On 1 Mar 1965, As a test, the first launch of an ICBM from an operational base was made from Ellsworth AFB. A short-range, tethered, and unarmed Minuteman I missile was launched.

On 1 June 1971, SAC inactivated the 821st Strategic Aerospace Division and by October of that year, an upgraded [[LGM-30F Minuteman II]] also replaced the Minuteman I missiles.

After the Berlin Wall fell in October 1989 a period of rapid change culminated in the President ordering all strategic nuclear alert operations to stand-down and the Cold War was over.

On 3 Dec 1991, the first Minuteman II missile was removed from its silo and on 6 Apr 1992, the first Minuteman II launch control center shut down. Inactivation of the entire Minuteman II missile complex ended in April 1994. Under conditions of the Strategic Arms Reduction Treaty, all of the 44th Missile Wing's Minuteman silos and launch control centers were slated for demolition with the exception of Sites Delta-01 and Delta-09. These two sites were turned over to the National Park Service for preservation as part of the Minuteman Missile National Historic Site.
