This is a brief guide to researching records of Royal Air Force squadrons, as opposed to records of RAF personnel. Most RAF squadron records have survived and are fairly detailed. They are held in a variety of places, but the majority are at The National Archives.

What do I need to know before I start?

The Royal Air Force was formed in 1918, towards the end of the First World War. Most operational records of its predecessors can be found in AIR 1 and AIR 2.

What records can I see online?

Operations record books of squadrons (1911-c1960)

Search the operations record books (AIR 27) by squadron number and date range on Discovery, our catalogue (£).

‘Summary of events’ forms, also known as form 540, and ‘detail of work carried out’ forms, also known as form 541, can be found in operation record books. These forms are records of the daily events of all RAF units.

Operations record books for later years (c.1960-1980) are not yet available online but can be viewed at The National Archives at Kew (see below).

Air Ministry Combat Reports (1939-1945)

Search and download Second World War RAF combat reports (AIR 50) in our catalogue. The records include reports from squadrons, wings and groups in Fighter, Bomber, Coastal Commands and Fleet Air Arm squadrons. They cover Commonwealth and Allied units based in the United Kingdom including the United States Army Air Force.

What records can I find only at The National Archives at Kew?

Operations record books of squadrons (c1960-1982)

Search AIR 27 by squadron number or name to find relevant operations record books.

Operations record books of stations and miscellaneous units (1911-1980)

Search our catalogue for operations record books of stations (AIR 28) and miscellaneous units (AIR 29) for details of the daily events and operations of any RAF unit. You can also add keywords such as training.

To access these records you will either need to visit us, pay for research (£) or, where you can identify a specific record reference, order a copy (£).

What records can I find in other archives and organisations?

Non-operational crashes and casualties (1918-present)

Browse the Ministry of Defence Air Historical Branch website for information on tracing records of crashes and casualties which occurred on non-operational flights from 1918 onwards. These do not usually contain personal details.

What other resources will help me find information?


Browse the RAF website for a list of current and historic squadrons and information on their histories, badges, aircraft, and battle honours.
