This list of regiments of the Royal Artillery covers the period from 1938, when the RA adopted the term 'regiment' rather than 'brigade' for a lieutenant-colonel's command comprising two or more batteries, to 1947 when all RA regiments were renumbered in a single sequence.

In 1938 the RA was organised in two main branches: Field, and Coast Defence and Anti-Aircraft (CD&AA) (including anti-tank). The two branches had separate depots and administrative staffs, but the main difference was in equipment and tactical employment. However, these differences broke down as World War II progressed, when units took on multiple roles, good examples being the employment of heavy anti-aircraft guns in the medium artillery and anti-tank roles.

In this list 'Reg' denotes a prewar unit of the Regular Army, 'SR' denotes Supplementary Reserve, 'TA' denotes Territorial Army, including duplicate units; all others were 'war-formed' (even if some were apparently designated TA). TA duplicate units were granted their subsidiary titles in February 1942. 'Mixed' indicates a unit in which a large proportion of the personnel were women of the Auxiliary Territorial Service. 'S/A' indicates an established Regular or TA unit placed in 'suspended animation' (as opposed to disbandment)

Royal Horse Artillery

Traditionally the Royal Horse Artillery (RHA) provided highly mobile light field guns to support cavalry formations. By 1939 the RHA was – like the rest of the RA – completely mechanised, but its role remained essentially the same: provision of mobile artillery to armoured formations. As World War II progressed, this was increasingly achieved using Self-Propelled (SP) guns. The following regiments were designated RHA for all or part of the period:

• 1st Regiment Royal Horse Artillery (Reg)
• 2nd Regiment, Royal Horse Artillery (Reg)
• 3rd Regiment Royal Horse Artillery (Reg) – 3rd Ant-Tank Regiment, RHA, 1941–2
• 4th Regiment, Royal Horse Artillery (Reg)

Searchlight

The following anti-aircraft searchlight (S/L) regiments served with the Royal Artillery during the period.

Anti-Aircraft 'Z' Rocket

Anti-Aircraft Z Regiments were armed with rockets fired from a simple launcher. Later in the war they could include some ATS personnel and many batteries were manned by the Home Guard with regular army command post staff. Some independent batteries served abroad. All Anti-Aircraft Z Regiments were redesignated Anti-Aircraft Area Mixed Regiments in April 1944 and all were disbanded by April 1945.

Maritime

The Maritime Anti-Aircraft Regiment Royal Artillery initially had 3 Light Machine Gun Regiments each with two batteries and one regiment of a battery of Bofors 40 mm. Port detachments were formed to find pools of trained Light Machine Gun gunners who could be embarked as required. Eventually the machine guns were mostly replaced by 20 mm Oerlikons and 40 mm Bofors. There was no higher formation, each commanding officer reporting direct to RA6 at the War Office. In September 1942 a gunner Brigadier was appointed as commander and in January 1943 the regiment was re-titled Maritime Royal Artillery. In March 1943 numbers were increased and the regiment organised into six regiments and twenty-four port detachments in Britain. There were four overseas batteries at New York, Port Said, Bombay and South Africa and four independent troops at Freetown, Sydney, Algiers and Haifa. A fifth troop was added later at Naples. In August 1945 the regiment was re-organised into 1st, 4th and 5th Regiments each with an RHQ, Training Battery and Holding Battery. There was also 2nd Regiment in India but this was not fully formed.

Infantry and Garrison Regiments

Garrison Regiments

Towards the end of 1944 Britain's field armies were suffering a manpower crisis, so the Royal Artillery began converting surplus air and coast defence regiments into Garrison regiments for service in rear areas.

Infantry Regiments, RA

By the beginning of 1945 the manpower crisis had deepened, and the garrison regiments were converted into infantry regiments for service on the lines of communication and occupation duties, together with other surplus regiments. Although formally these units were entitled 'Regiments, RA', the word 'Infantry' is often added (then and subsequently) for clarity.
