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.

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.
