Colorado military construction during the
buildup of US training installations prior to the
bombing of Pearl Harbor included the 1940
Lowry bombardier school at
Denver and
Camp Carson south of
Colorado Springs (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
city auditorium ... and the mess hall was located at the busy horseshoe counter of the
Santa Fe railway station." Land at
the Broadmoor was used for maneuvers, and the 2nd Group initially operated without aircraft. Personnel were also "housed temporarily at
Colorado College" and a youth camp near the Woodmen sanitorium. (the
14th Photographic Reconnaissance Squadron was located at the Kaufman Building on Tejon St.)
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 [on] 11 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". 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
eponym 1st Lt Edward J. Peterson crashed 8 August 1942 on
take off (1st Coloradoan killed at the airfield.)
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 [air]field 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. During planning for the new
United States Air Force, Colorado's
Arlington Auxiliary Army Airfield became a detached installation of the surplus base (1 January – 1947), and the "468th Construction Co (15th AF)" became the inactive base's operating unit in February 1947. The base with new construction was activated 29 September 1947 – 15 January 1948, then was "surplus" until after the notice in November 1950 to reactivate
Air Defense Command. The "23 Photo Sq 19 May 1943-9 August 1948" remained throughout both inactive/surplus periods, and the "4600 Maint & Sup Sq" was established at the surplus base on 1 December 1950).
USAF installation at Peterson as it appears after the 20th anniversary commemoration of the event, with wreaths laid, on September 11, 2021. 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
Air Intelligence Service Squadron had subordinate organizations at the "Defense Force Headquarters [on]
Hamilton Air Force Base, California, at
Kansas City, Missouri, and at
Stewart Air Force Base" New York. The 4600th Group became the
4600th Air Base Wing on 8 April 1958 (moved to Peterson on 18 October 1972). The 4600th was replaced by the
46th Aerospace Defense Wing on 1 April 1975. In January 1968,
Air Training Command's 3253d Pilot Training Squadron at Peterson Field began light aircraft indoctrination for cadets. These operations moved to the
United States Air Force Academy on 21 March 1974. The military base at Peterson Field gained its own base commander on 28 February 1975.
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
Strategic Air Command" on 1 October 1979 (units transferred included the 47th Comm Sq to
AFCS and the 46th Wing and 4602nd Computer Services Sq to SAC). ADCOM HQ offices at the
Chidlaw Building became the
Aerospace Defense Center at Peterson on 1 December 1979. Peterson's NORAD COC Backup Facility achieved
Full Operational Capability on 16 November 1982 from the
Cheyenne Mountain Complex which was placed on warm standby. 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.
Posting the Colours at the Air Force birthday ceremony, September 2016. 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. The base's Retiree Activities Office has the representative for the Air Force Retiree Council Area IV (
Colorado,
Nevada,
Utah, and
Wyoming). On 20 December 2019, Air Force Space Command was redesignated as the
U.S. Space Force and elevated to become an independent military branch. With the new military branch, the Fourteenth Air Force and its units became Space Force
Space Operations Command and Air Force Space Command's headquarters was redesignated as the Pentagon. == Based units ==
