RAF Army Cooperation Command

RAF Army Cooperation Command was a Royal Air Force formation formed to improve liaison with the British British Army and to provide reconnaissance, artillery spotting, and close support for field formations during the early years of World War II. Established amid debates in the Air Ministry and between service leaders such as Sir Archibald Sinclair and field commanders from the British Expeditionary Force and later the Home Forces, the Command sought to coordinate doctrine between the Royal Artillery, Royal Engineers, and air arms. It operated alongside commands such as RAF Fighter Command, RAF Bomber Command, and RAF Coastal Command while responding to lessons from campaigns including the Battle of France and the Norwegian Campaign.

History

Created in 1940 in the aftermath of the Battle of France and the evacuation from Dunkirk, the Command responded to criticisms from figures like Lord Gort and the Chief of the Imperial General Staff, Sir Alan Brooke, about the RAF’s support for army operations. Early organizational debates involved the Air Council, proponents such as Sir Richard Peirse, and Army advocates tied to the Middle East Command and Home Forces. The Command underwent rapid development during the Battle of Britain period as aircraft types and liaison techniques were reassessed by staff from RAF Training Command and RAF Technical Training Command. By 1943, changing operational priorities, lessons from the Western Desert Campaign and the establishment of integrated formations in the Allied Expeditionary Air Force led to its functions being absorbed back into other RAF structures and Army air liaison arrangements advocated by leaders like Sir John Dill.

Organisation and units

The Command’s order of battle included dedicated squadrons and wings drawn from the Royal Air Force Volunteer Reserve, regular RAF squadrons, and the Air Observation Post (AOP) Squadrons formed from Royal Artillery officers and RAF pilots. Units were based at stations such as RAF Benson, RAF Odiham, RAF Northolt, and RAF Lympne, and coordinated with army formations including I Corps (United Kingdom), II Corps (United Kingdom), and home defence brigades. Subordinate formations included reconnaissance wings aligned with Northern Command, Southern Command, and experimental flights from Central Flying School. Liaison involved close interaction with the Royal Corps of Signals, the General Staff, and schools such as the School of Artillery and the Staff College, Camberley.

Operations and roles

Operationally, the Command performed tactical reconnaissance, artillery spotting, photographic reconnaissance, meteorological reconnaissance, and visual liaison for formations from British Expeditionary Force remnants to home defence units. Missions supported campaigns and exercises tied to the Home Guard preparation, coastal defence planning near the English Channel, and training in combined operations with units earmarked for the Dieppe Raid planning and later Operation Overlord preparations. Its crews worked with army staff on procedures for target marking, signals procedures with the Royal Corps of Signals, and air-ground interaction lessons derived from encounters with German units such as the Wehrmacht during 1940–1941 operations.

Equipment and aircraft

Aircraft employed included liaison and observation types such as the Auster AOP, light reconnaissance types like the Westland Lysander, the army-cooperation versions of the Hawker Henley, and some use of twin-engined photographic machines formerly used by RAF Photographic Reconnaissance Unit. Training and support used types from Avro Anson inventories and communication aircraft from the de Havilland Dragon Rapide series. Ground equipment incorporated radio sets interoperable with Royal Corps of Signals standards, map reproduction gear linked to Ordnance Survey procedures, and artillery spotting kits used alongside the Royal Artillery’s fire-control instruments.

Commanders

Senior commanders and directors associated with the Command included Air Officers who had served in interwar postings with links to RAF Training Command and theater commands in the Middle East Command and Far East Command. Notable senior figures who influenced doctrine included officers formerly of RAF Coastal Command and the Royal Flying Corps in World War I; these leaders engaged with Army chiefs like Sir Edmund Ironside and staff officers from the Imperial General Staff on doctrine and training.

Legacy and impact

Although disbanded and subsumed by reorganized RAF structures by 1943, the Command’s experimentation with air-ground coordination influenced later Anglo-American tactics used in the Normandy campaign, contributed to doctrines adopted by postwar formations such as the Army Air Corps and affected postwar training at establishments including the RAF College Cranwell and the Joint Services Command and Staff College. Its work on liaison, reconnaissance, and tactical air support informed NATO procedures in the early Cold War era and doctrines discussed at meetings involving the Western Union and early NATO staffs.
