History
The 25th SRS has a proud legacy that traces its origins to the beginning of aerial warfare. It was originally organized as the 20th Aero 
Squadron on June 13, 1917 and formally designated the 25th AS June 22, 1917. As pioneers of military aviation, the 25th was trained to fly 
British-made SE-5 aircraft and sent to France to participate in combat operations during the Meuse-Argonne Campaign. Following the war, 
the 25th Aero Squadron was stationed at Mitchell Field, New York until demobilized on June 17, 1919. 

Fast-forward to July 1, 2004, Air Force Space Command again activated (after several other changes along the years) the 25th, this time as the 25th Space Control Tactics Squadron with a mission to develop and document space tactics, operate the Space Range and propagate 
approved tactics and space control employment concepts to warfighters. 

However, Nov. 11, 2007, the squadron was re-designated the 25th SRS to acknowledge the growing importance of its mission; operating the 
nation's only Space Test and Training Range in direct support of the DoD. On July 24, 2020 the unit was reassigned to U.S. Space Command and attached to Space Training and Readiness Delta (Provisional).
