Upon the formation of the Royal Air Force in 1918, rank titles and badges for ORs were adopted from the British Army, specifically the Royal Flying Corps (RFC). The RFC ranks of Warrant Officer Class I, Warrant Officer Class II, Flight Sergeant, Sergeant and Corporal were directly adopted, although the four-bladed propeller above the Sergeants' and Flight Sergeants' chevrons was dropped. The double-bladed propeller used as the badge of rank for an RFC Air Mechanic 1st Class was introduced as the trade classification badge for Leading Aircraftman. The rank of Aircraftman replaced the RFC rank of Air Mechanic 2nd Class.

In 1939, the ranks of Warrant Officer Class I and Warrant Officer Class II were combined as a single rank, Warrant Officer. RAF warrant officers were given equivalent status to the continuing Army rank of Warrant Officer Class I.

On 1 July 1946, NCOs serving as aircrew were assigned different rank badges which distinguished them from ORs in ground trades. The new ranks were:

• Master Aircrew (equivalent to Warrant Officer)
• Aircrew I (equivalent to Flight Sergeant)
• Aircrew II (equivalent to Sergeant)
• Aircrew III (equivalent to Sergeant)
• Aircrew IV (equivalent to Sergeant)
• Aircrew Cadet (for trainee aircrew)

In 1950, a new grading system for technicians was introduced. This involved the creation of the following ranks:

• Master Technician (for Warrant Officers in technical trades)
• Chief Technician (for Flight Sergeants in technical trades) with three inverted chevrons surmounted by a crown
• Senior Technician (for Sergeants in technical trades) with three inverted chevrons
• Corporal Technician (for Corporals in technical trades) with two inverted chevrons
• Junior Technician with one inverted chevron

Also in 1950, the unpopular NCO aircrew ranks were abolished, although Master Aircrew was retained as a rank. Aircrew I became Flight Sergeant Aircrew and Aircrew II, III and IV became Sergeant Aircrew. Both new ranks adopted a gold eagle above the cheverons to permit continuing distinction from ground trades. Aircrew Cadets wore the eagle on its own.

On 1 January 1951, two junior ranks were introduced:

• Senior Aircraftman (or Senior Aircraftwoman) with a triple-bladed propeller.
• Leading Aircraftman (or Leading Aircraftwoman) with a double-bladed propeller (this had previously been only a trade classification and not a rank)

In 1964, the technician ranks were abolished, with the exception of Junior Technicians and Chief Technicians, the latter becoming an intermediate rank between Sergeant and Flight Sergeant for Technical Trades. Junior Technicians adopted the four-bladed propeller as their badge of rank and Chief Technicians adopted a treble cheveron surmounted by a four-bladed propeller as their rank insignia. Master Technicians, Senior Technicians and Corporal Technicians all reverted to their former ranks of Warrant Officer, Sergeant and Corporal respectively. The ORs structure became:

• Warrant Officer / Master Aircrew
• Flight Sergeant / Flight Sergeant Aircrew
• Chief Technician
• Sergeant / Sergeant Aircrew
• Corporal
• Junior Technician
• Senior Aircraftman (or Senior Aircraftwoman)
• Leading Aircraftman (or Leading Aircraftwoman)
• Aircraftman (or Aircraftwoman)
