# List of Royal Air Force aircraft squadrons

Squadrons are the main form of flying unit of the Royal Air Force (RAF). These include Royal Flying Corps (RFC) and Royal Naval Air Service (RNAS) squadrons incorporated into the RAF when it was formed on 1 April 1918, during the First World War. Other squadrons of the RAF include those from Commonwealth air forces which have served within the RAF structure and squadrons of the Fleet Air Arm before it transferred to the Royal Navy in 1939.
Some squadrons have an individual tradition of presenting their squadron number in Roman numerals or using a suffix to their squadron number (such as "(F)" for "Fighter", "(B)" for "Bomber" or "(AC)" for "Army Co-operation") to indicate a past or present role. An example would be No. 18 (Bomber) Squadron RAF which currently actually operates the heavy-lift Chinook helicopter. However, these practices have, at least in the past, been deprecated at higher levels and generally only apply to certain squadrons with long traditions, especially those numbered from 1 to 20. Historical Squadrons can choose to 'lay up' their standards at RAF Cranwell or in places of worship following disbandment.
Flying training units and operational evaluation squadrons have generally been (Reserve) squadrons, although they are regular active-duty units. The policy of the (Reserve) numberplate was rescinded in February 2018, to coincide with the renaming of 22 (Training) Group to just 22 Group in line with other RAF Groups.
Some Squadron names include the location they were originally formed.

## Nos. 300–352

Squadrons in the 300–352 series were staffed during the Second World War by volunteers from countries in occupied Europe. In some cases, these RAF squadrons and personnel were regarded by a relevant government-in-exile as serving concurrently with its air force.
Similarly, in 1940–42, three "Eagle Squadrons" were composed of volunteers from the US: No. 71 (Eagle) Squadron, later 334th Fighter Squadron USAAF; No. 121 (Eagle) Squadron, later 335th Fighter Squadron USAAF and No. 133 (Eagle) Squadron, later 336th Fighter Squadron USAAF.

## University Air Squadrons

The majority of Universities in the United Kingdom are, or have been, represented by Royal Air Force (RAF) University Air Squadrons (UAS), where under-graduates can sample elements of the Royal Air Force, and learn to fly, as well as take advantage of scholarship schemes. Previously operating the Bulldog T.1, they now all currently operate the Tutor T.1. Although each UAS retain their own identity an activities, when two are co-located at the same airfield, such as Cambridge UAS and London UAS at RAF Wittering, and Liverpool UAS and Manchester and Salford UAS at RAF Woodvale, the two individual UAS share the same fleet of aircraft. All University Air Squadrons are currently commanded by No. 6 Flying Training School RAF (6FTS).
Squadrons below listed in bold are currently active, others are disbanded, or otherwise amalgamated into a current existing UAS.

## Volunteer Gliding Squadrons

Initially formed as Gliding Schools (GS), and then renamed Volunteer Gliding Schools (VGS), these squadrons retained their gliding school numbers when reformed as squadrons. Conflicts with the main squadron numbers resolved by the VGS suffix. The currently active squadrons, now part of 2 Flying Training School (2FTS) headquartered at RAF Syerston along with the Central Gliding School, all operate the Viking T1 winch-launched sailplane glider.

## Independent Flights

The Royal Air Force (RAF) maintains a number of independent flights; some on a permanent basis, others on an ad-hoc basis as required. Historically, some flights were alphabetically named. For a full list, see the list of Royal Air Force aircraft independent flights. Bold listings are currently active RAF flights.
* Battle of Britain Memorial Flight (BBMF) – at RAF Coningsby – 6x Spitfire (various marks), 2x Hurricane, 1x Lancaster, 1x Dakota, 2x Chipmunk T10
* No. 1310 Flight – 2x Chinook HC5, HC6, HC6A
* No. 1312 Flight – at RAF Mount Pleasant – 1x Voyager KC2, 1x Atlas C1
* No. 1435 Flight – at RAF Mount Pleasant – 4x Typhoon FGR4

## Dormant Squadrons

RAF College Cranwell stores some Standards for disbanded Squadrons that have the potential to be re-activated in the future, preserving the heritage of historic units. Once a Squadron Standard is 'laid up' in a place of worship, upon the disbandment of the Squadron, that Standard can no longer be reactivated. Many UK churches have Standards from the RAF following a service of Disbandment. However, some Squadrons choose to lay up their Standards in College Hall at RAF Cranwell, the spiritual home of the RAF, and may be reactivated as active Squadrons in the future. Old disbanded squadrons that have laid up their Standards can be presented new Standards to reactivate them, but this is currently extremely rare.
Squadron Standards (and their last operated aircraft) that are on display in the College Hall Rotunda in order of seniority are:
* No. 47 Squadron – Hercules C4/5
* No. V (Army Cooperation) Squadron – Sentinel R1
* No. 100 Squadron – Hawk T1
* No. 39 Squadron – MQ-9A Reaper
* No. 111 Squadron – Tornado F3
* No. XV Squadron – Tornado GR4
* No. 203 Squadron – Sea King HAR3
* No. 50 Squadron – Vulcan B.2/K.2
* No. 74 Squadron – Hawk T1
* No. 44 Squadron – Vulcan B.2
* No. 3 Squadron RAF Regiment
* No. 58 Squadron RAF Regiment

### Communication Squadrons

To allow rapid transport of Air Officers, staff and other important people many units and Headquarters operated communication Sections, Flights, Squadrons or wings.

### Barrage Balloon Squadrons of the Auxiliary Air Force
## Squadron codes

Most units of the Royal Air Force are identified by alphabetical (or similar) characters, known as a "squadron code", that is painted on all aircraft belonging to that unit. When individual units are assigned unusually large numbers of aircraft, multiple squadron codes have been used.
Other air forces, especially those from other Commonwealth countries, have often used similar systems of identification. During the Second World War, when units from other air forces were attached to the RAF – such as the Article XV squadrons (also known as "400 series squadrons") – their squadron codes were often changed, to avoid confusion with RAF units.
Historically, the codes have usually been two letters of the alphabet, painted on the rear fuselage next to the RAF roundel. These formed a suffix or prefix to the call sign of each aircraft (on the other side of the roundel) which was usually a single letter (e. g. "G for George"). In general, when an aircraft is lost or withdrawn from use, its call sign has been applied to its replacement or another aircraft.
