• RAF Bomber Command (Air Marshal Sir John Steel, headquarters in Uxbridge)
• RAF Fighter Command (Air Marshal Sir Hugh Dowding, headquarters in Stanmore)
• RAF Coastal Area becomes RAF Coastal Command (Air Marshal Sir Arthur Longmore, headquarters in Lee on Solent).
• A fourth command, RAF Training Command, had been formed on 1 May 1936.

21 July
The King's Flight of the Royal Air Force is officially formed for the first time.

30 July
Royal Air Force Volunteer Reserve (RAFVR) is formed. It is initially envisaged that the RAFVR would recruit 800 reservists a year for pilot training between 1936 and 1938 and provision is also made for recruiting 2,500 observer trainees and 3,200 wireless operator (air gunner) trainees. However, as international tension heightens, recruiting targets sre increased.

17-24 September
The first full-scale trials of a Radio Direction Finding (RDF), or radar, system are carried out by the Royal Air Force, using experimental equipment located at Bawdsey Research Station to track Royal Air Force Coastal Command Avro Ansons operating from RAF Manston and flying boats operating from Felixstowe. Although the results of the trial are mixed, the Chief of the Air Staff concludes that they have proved the concept of an RDF system and justified the development of RDF as part of the air defences of the United Kingdom.
