The 21st Operations Group (21 OG) is an operational component of the 21st Space Wing, stationed at Peterson Air Force Base, Colorado.

The mission of the 21st OG is to provide overall management and guidance to 21 geographically separated units assigned to the wing, which provide attack warning and space control. Its history goes back to World War II when the 21st Fighter Group flew very long range (VLR) escort missions of Twentieth Air Force B-29 Superfortress bombardment groups against Japan. During the Cold War, the unit was a USAFE tactical fighter unit assigned to France in the 1950s and later controlled all operational fighter squadrons at Elmendorf AFB, Alaska.

Overview

Responsibilities include establishment of operational requirements and managing the training, standardization and evaluation programs. This includes conducting command-directed evaluations and staff assistance visits. Additionally, the 21st OG develops and maintains operational procedures and regulations for field units.

The 21st OG funnels Defense Support Program satellite information to forward users, and the Cheyenne Mountain Air Force Station missile warning. The group is also the focal point for the Air Force's transition from DSP to the new Space-Based Infrared Satellite system.

Constituted as 21st Bombardment Group (Medium) on 13 January 1942. Activated on 1 February 1942 at Bowman Field, Kentucky. Thereafter, from February 1942 until October 1943, the group relocated successively to Jackson Army Air Base; Mississippi; Columbia Army Air Base, South Carolina; Key Field, Mississippi, and MacDill Field, Florida.

The 21st initially trained on B-25 Mitchell bombers then converted to B-26 Marauders. The group largely served as an operational training unit assigned to Third Air Force; however, while at MacDill Field, from June 1942 to October 1943, the 21st additionally carried out anti-submarine patrols over the Caribbean Sea. For this action the group received the Anti-Submarine 1941–1945 campaign streamer. The 21st inactivated on 10 October 1943.

The 21st did not have to wait long to write a further chapter in the history of warfare. Another unit, the 21st Fighter Group (FG), activated on 21 April 1944 at Wheeler Army Airfield in the Hawaii Territory. Assigned to VII Fighter Command, the group consisted of the 46th, 72d, and 531st Fighter Squadrons. Over the next two months, the group trained on its first aircraft type, the P-39Q Airacobra. The 21st provided air defense over the Hawaiian Islands from July 1944, then began upgrading into the P-38J/L Lightning in September.

By the end of October, rumors filled the air that the group soon would upgrade airframes again, this time to the P-51 Mustang. This change in aircraft heralded a new mission for the 21 FG. True to rumor, leading echelons began deploying by ship to the island of Iwo Jima in the western Pacific in February 1945.

Before the end of the month, the 21st began flying patrols over the critical island base in support of ground operations. The final group echelon arrived at Iwo Jima on 25 March. Early the next morning, elements of the 21st were attacked in their encampment by Japanese soldiers. Assisted by a patrol of American Marines, 21st personnel counterattacked and in the tent-by-tent fighting killed 250 of the enemy. Fourteen group personnel were killed and 50, including 21 FG commander Colonel Kenneth R. Powell, were wounded.

The first long-range aerial mission of the 21st Fighter Group against the mainland of Japan began on 7 April 1945, when the group’s Mustangs escorted a formation of B-29 bombers against the fortified and well-defended Nakajima aircraft factory near Tokyo. This mission marked the first time fighters had escorted bombers over Japan. Moreover, this mission has been credited as having been the longest over-water fighter escort sortie to date. Over the following weeks, the 21st escorted American B-29s over enemy airfields and industrial targets and engaged rival Japanese fighter aircraft. The 531st Squadron achieved another first for the 21 FG in June 1945 by initiating aerial rocket strike sorties against select enemy targets which included ships and a radio station. In the meantime, the groups’ aircraft continued to duel in the air and two “aces” soon emerged: Major Harry Crim and Captain Willis Matthews, both of the 531st Fighter Squadron. Aircrews of the 21st also strafed the airfields which the Japanese used for their increasingly dangerous kamikaze attacks. The 21 FG flew its last combat mission 14 August 1945, about two weeks before the official Japanese capitulation on 2 September.

The group received the Distinguished Unit Citation on 13 November 1945 specifically for its outstanding conduct during the earlier raid on Nakajima. However, the 21st had played a laudable part throughout the final stages of the war in the Pacific.

After the war, the group transferred from Iwo Jima, first to Saipan, then finally to Guam. Re-equipped with P-47 Thunderbolts during the summer of 1946. The 21 FG inactivated on 10 October 1946.

Post/Cold War

The tail of the F-86 to the left is serial 52-5263, which was destroyed in an accident 4 June 1974

Redesignated 21st Fighter-Bomber Group. Activated at George AFB California on 1 January 1953 with three (72d, 416th and 531st) Fighter-Bomber squadrons. Assigned to Tactical Air Command. Equipped for a few months with F-51's, later with F-86's. Maintained tactical proficiency and provided air defense augmentation in the United States, January 1953 – November 1954.

At George, the group established and maintained tactical proficiency and provided air defense augmentation. In December 1954, the group was assigned to NATO and was reassigned to Chambley-Bussieres Air Base, France.

The 21 FBG consisted of three squadrons, the 72d, 416th and 531st Fighter-Bomber Squadrons, equipped with the F-86F Sabre. Upon their arrival, the facilities at Chambley were not ready for aircraft use, and the squadrons had to deploy elsewhere. The 72d deployed to Chateauroux AB, while the 416th and 531st operated out of Toul-Rosieres AB.

After many construction delays, the group combined its fighter squadrons at Chambley on 15 April 1955. The squadrons carried out close air support training missions with the Army, then took first place at the United States Air Forces in Europe (USAFE) "Gunnery Meet" at Wheelus Air Base, Libya.

The 21 FBW participated in the Atomic Warfare exercise Carte Blanche, and went on to take an overall second place in the Nellis AFB, Nevada Gunnery Meet in 1956. Moreover, they won the USAFE Award for Tactical Proficiency for the January–June period of 1957.

In 1957, the French Government decreed that all nuclear weapons and delivery aircraft had to be removed from French soil by July 1958. As a result, the F-86's of the 21st Fighter-Bomber Group had to be removed from France. During October 1957 it was announced that the 21 FBG would be inactivated on 8 February 1958, and that its assets would be dispersed among existing USAFE units.

Modern era

In 1991, the 21st Tactical Fighter Wing was reorganized as an objective wing and all the major tenant units on Elmendorf AFB, Alaska were placed under it. The 21st Operations Group was the flying component of the 21st Wing. The 21st Wing was inactivated and the 3d Wing was reassigned from Clark Air Base, Philippines to Elmendorf on 19 December 1991 as a result of the Mount Pinatubo eruption and the inhabitability of Clark. This was in keeping Air Force's polices of retaining the oldest and most illustrious units.

The 21st Operations Group was reactivated on 15 May 1992 as a component of the redesignated and reactivated 21st Space Wing, providing command management of Air Force Space Command's worldwide network of assigned missile warning, space surveillance, and communications units.
