(HQ completed on 31 January 1942). Sites "in the vicinity of Colorado Springs" were assessed in the summer of 1941 for a
USAAF airfield, and during April 1942 the
Photographic Reconnaissance Operational Training Unit (PROTU) was activated in a leased facility at Colorado Springs. On 6 May 1942, the site adjacent to the airfield of the 1926 Colorado Springs Municipal Airport was selected, and the airport's airfield was subsequently leased as an "air support field"* for Camp Carson under the "air support base development program". In May 1942, units such as the
5th Mapping Squadron (from
Bradley Field) arrived and used city facilities. The "
Second Photographic Group Reconnaissance" (activated 7 May 1942 at
Will Rogers Field) transferred to Colorado Springs, and the "2nd Group ... headquarters was situated in a former garage across the street from the Post Office, barracks were in the

Army Air Base, Colorado Springs
"Army Air Base, Colorado Springs",* construction began after 10 May 1942, on "nothing more than a large patch of Colorado plain", and the installation was placed under the Headquarters,
United States "AAF n11 June 1942". The 373d
Base HQ and Air Base Sq was activated as the base operating unit on 20 June 1942 (replaced by the 214th
AAF Base Unit in 1944), and the base was assigned to the
2nd Air Force on 22 June 1942. On 7 July 1942, "HQ PROTU" was on the "Army Air Base, Colorado Springs" and was ordered to provide "four to five months of training to each individual".
[HQ Memo to HQ PROTU, 7 July 1942 (quoted by First Installment)] During air base construction, the
20th Combat Mapping Squadron was activated on 23 July 1942, and used the Alamo Garage on Tejon Street. Runways were completed in August 1942, and

Peterson Field
Peterson Field was the airfield named on 13 December 1942, and included the runway used by both the municipal airport and the military installation: "Army Air Base, Peterson Field", which had begun publishing the ''Wingspread'' base newspaper by 11 July 1942. The "18 Dep Rpr Sq" was assigned to the military installation from 19 January – 29 April 1943, and the installation was assigned to the
Third Air Force (5 March – 1 October 1943) and by the end of the 1943 summer had tar paper barracks, an officer's club, and a theater in a
Quonset. After the base transferred to
Second Air Force on 1 October 1943, in June 1944 Peterson Field began fighter pilot training with
P-40N Warhawks. "In March 1943 the
Third Air Force took over the photographic reconnaissance Operational Training Unit which had been operating at Peterson Field ... under the direct control of the Director of Photography since April 1942".

Bomber Commands
The 4th
Heavy Bombardment Processing Headquarters ("4 H Bomb Processing HQ") was activated on 10 June 1943 (the 1st B-29 landed at Peterson Field in the summer of 1943), and bomber training by the 214th AAF Base Unit (Combat Crew Training School, Heavy)
B-24 Liberator) began after the
383rd Bombardment Group relocated from
Geiger Field, Washington on 26 October 1943. In 1944 (11 June – 20 October), the
XXI Bomber Command was assigned to Peterson; and the "HQ and HQ Sq" of
XXII Bomber Command was assigned 14 October 1944 – 13 February 1945, and by 17 August 1944, 4 bomb wings (313th through 316th) were assigned to the base — the last left on 7 June 1945. The
263rd AAF Base Unit became the Peterson "base operating unit" on 8 March 1945 (transferred to
Andrews Field on 17 March 1946). The
Army Air Forces Instructor School opened at Peterson Field in April 1945, and the base was one of several that transferred to
Continental Air Forces on 16 April 1945. (
VIII Bomber Command arrived 17 August 1945).
The base was inactivated 31 December 1945 after the
13th Bombardment Wing (17 October) and
VIII Bomber Command () departed, and site management by the base operating unit ended on 17 December 1945. In 1946, Peterson's last AAF Base Units were discontinued: 260th AAF Base Unit (Fighter Wing) in January, the 202nd AAF Base Unit (Special) in February, and the 268th AAF Base Unit (Instrument Instructor Unit) in March and the 201st (Headquarters Base Unit) in April (the
72nd Fighter Wing was at the base from "4 January 1946 - 9 April 1946"). The 703rd AAF Base Unit (Hq, 53d AACS Group) moved to Kelly Field in February. Designated surplus on 29 July 1946, "the U.S. Government returned control of the
irield to the City of Colorado Springs". Many of the base buildings were torn down. In 1946,
Tonopah AAF (Nevada, on 1 October),
Clovis AAF (New Mexico, 16 October), and
Casper AAF (Wyoming, on 15 December) became detached installations of the inactive base for a short period.

USAF installation

The military base at the municipal field reactivated as an off-base installation of
Ent Air Force Base on 1 January 1951 and was operated by Ent's 4600 Air Base Group. After being assigned to Peterson on 1 March 1952, the 4602d

Primary installation
Designated Peterson Air Force Base on 1 March 1975, when Ent AFB was being closed, Peterson was the last of the April 1945
Continental Air Forces airbases to be named an air force base. Also on 1 March, Peterson assumed several functions from Ent AFB, which became the "Ent Annex" of Peterson, 18 July 1975 – 7 February 1978 (Peterson's off-base "Temporary Military Facility" was opened for space training by 1986). During the first part of the reorganization that broke up ADCOM, the base "transferred to the

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

The
Cheyenne Mountain Realignment moved NORAD/USNORTHCOM operations to Peterson AFB in 2006. In 2006, the
76th Space Control Facility was constructed at Peterson (the squadron activated 22 January 2008). The
MAFFS aircraft that fought the 2012
Waldo Canyon fire and 2013
Black Forest fire at Colorado Springs flew from Peterson AFB.
Some buildings from the Second World War have survived. Buildings remaining in 1996 were "the terminal, now the
Peterson Air and Space Museum, the Broadmoor hangar, and the Spanish House" next to the museum, along with Building 391, Building 365, supply warehouses and office buildings, and aircraft hangars and maintenance shops.

Despite the number of vintage records with "Army Air Base, Colorado Springs", Mueller in 1989 (p. 471) claims the military installation next to the municipal airfield was initially named "Air Support Command Base" in May 1942, but does not identify an Air Support Command headquarters ever being at the air base, nor that base was even assigned to one of the support commands.
