List of Air Training Corps squadrons

The Air Training Corps (ATC) is a cadet organisation based in the United Kingdom. It is a voluntary youth group which is part of the Air Cadet Organisation of the Royal Air Force. The ATC is largely composed of individual units known as squadrons. These squadrons are organised into several different Wings, which in turn are organised into six different Regions. Together the Regions make up the Corps.

Headquarters Air Cadets (HQAC) is located at Royal Air Force College Cranwell, Lincolnshire and headed by Commandant Air Cadets Air Commodore Dawn McCafferty.

The first 50 squadrons formed have their squadron numbers followed by an F to show they are "founder" squadrons (e.g. No 38F (Perth) Squadron). Only 30 are still in existence, as the other 20 have disbanded over time. Founder Squadrons that have reformed after being disbanded do not retain the F status.

In towns not large enough to sustain a squadron of 30 cadets, or as a supplement to an existing squadron in a larger town or city, a Detached Flight may be formed. This operates much like any other unit, but is technically a component part of a nearby larger squadron. There are currently approximately 48 Detached Flights, denoted by the letters "DF" after a squadron number.
