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.
