The history of the Royal Air Force, the air force of the United Kingdom, spans nearly a century of British military aviation.

The RAF was founded in 1918, toward the end of World War I by merging the Royal Flying Corps and the Royal Naval Air Service. After the war, the RAF was greatly reduced in size and during the inter-war years it was used to "police" the British Empire. The RAF underwent rapid expansion prior to and during the Second World War. During the war it was responsible for the aerial defence of Great Britain, the strategic bombing campaign against Germany and tactical support to the British Army around the world.

During the Cold War, the main role of the RAF was the defence of the continent of Europe against potential attack by the Soviet Union, including holding the UK's nuclear deterrent for a number of years. After the Cold War, the RAF was involved in several large scale operations, including the Gulf War, the Kosovo War, the War in Afghanistan, the Iraq War.

  Formation and the inter-war years

  Formation

Whilst the British were not the first to make use of heavier-than-air military aircraft, the RAF is the world's oldest independent air force: that is, the first air force to become independent of army or navy control.^[1] The RAF was founded on 1 April 1918 by the amalgamation of the Royal Flying Corps and the Royal Naval Air Service and was controlled by the British Government Air Ministry which had been established three months earlier. The Royal Flying Corps had been born out of the Air Battalion of the Royal Engineers and was under the control of the British Army. The Royal Naval Air Service was its naval equivalent and was controlled by the Admiralty. The decision to merge the two services and create an independent air force was a response to the events of World War I, the first war in which air power made a significant impact. The creation of the new force was based on the Smuts Report prepared by Field Marshal Jan Smuts for the Imperial War Cabinet on which he served.

To emphasize the merger of both military and naval aviation in the new service, many of the titles of officers were deliberately chosen to have a naval flavour, such as flight lieutenant, wing commander, group captain, and air commodore.

The newly created RAF was the most powerful air force in the world on its creation, with over 20,000 aircraft and over 300,000 personnel (including the Women's Royal Air Force). The squadrons of the RFC kept their numerals while those of the RNAS were renumbered from 201 onwards. At the time of the merger, the Navy's air service had 55,066 officers and men, 2,949 aircraft,^[2] 103 airships and 126 coastal stations. The remaining personnel and aircraft came from the RFC. The RAF's last known surviving founder member was the World War I veteran Henry Allingham who died in 2009 aged 113. A memorial to the RAF was commissioned after the war in central London.

  Policing the Empire and activities in Great Britain

Following the end of World War I and the accompanying British defence cuts, the newly-independent RAF took up the task of policing the British Empire from the air. It was argued that the use of air power would prove to be a more cost-effective way of controlling large areas than by using conventional land forces. Sir Hugh Trenchard, the Chief of the Air Staff, had formulated ideas about the use of aircraft in colonial policing and these were first put into practice in 1920 when the RAF and imperial ground units defeated rebel Somaliland dervishes. The following year, in 1921, the RAF was given responsibility for all British forces in Iraq with the task of 'policing' the tribal unrest. The RAF also saw service in Afghanistan in 1928, when following the outbreak of civil war, the British Legation and some European diplomatic staff based in Kabul were cut off. The operation to rescue them, the Kabul Airlift, was the first evacuation of civilians by air.

It was during the inter-war years that the RAF had to fight for its survival^[3][4][5] - some questioned the need for a separate air force, especially in peacetime. To prevent itself being disbanded and its duties returned to the Army and the Navy, the RAF spent considerable energies keeping itself in the public eye by such things as the annual Hendon Air Show and by supporting a team for the Schneider Trophy competition. In 1936, a reorganisation of RAF command saw the creation of Fighter Command, Bomber Command and Coastal Command.

  Naval aviation

The creation of the RAF removed all aircraft and flying personnel from the Navy, although the Admiralty remained in control of aircraft carriers. On 1 April 1924, the Fleet Air Arm of the Royal Air Force was formed under Air Ministry control. It consisted of those RAF units that were normally embarked on aircraft carriers and fighting ships.^[6] The Chief of the Air Staff, Lord Trenchard, his air staff and his successors argued that "air is one and indivisible" and hence that naval aviation was properly the responsibility of the RAF. The Admiralty took the opposite view and, during the first half of the 1920s, pressed hard for the return of naval aviation to their control. It has been argued that the British defence arrangements in the inter-war years had a serious impact upon the doctrinal development of British naval air power as the Navy lacked experienced naval aviators.^[7]

During the 1920s and first half of the 1930s, Government spending on the RAF was limited and the air staff put a higher priority on strategic bombing than on naval aviation. The result of this was that by the late 1930s the Fleet Air Arm was equipped with outdated aircraft in limited numbers. By 1936, the Admiralty were once again campaigning for the return of naval aviation to their control. This time they were successful and on 30 July 1937, the Admiralty took over responsibility for the administration of the Fleet Air Arm. Under two years later, on 24 May 1939, the Fleet Air Arm was returned to full Admiralty control^[8] under the Inskip Award and renamed the Air Branch of the Royal Navy. The RAF name of the Fleet Air Arm remained in informal usage and was later adopted officially. Land-based aircraft of Coastal Command which defended the United Kingdom from naval threats remained under RAF control.

  Strategic bombing

The RAF developed its doctrine of strategic bombing which led to the construction of long-range bombers and became the basic philosophy in the Second World War.^[9]

  World War II (1939–1945)

The RAF underwent rapid expansion following the outbreak of war against Germany in 1939. This included the training of British aircrews in British Commonwealth countries under the British Commonwealth Air Training Plan, and the secondment of many whole squadrons, and tens of thousands of individual personnel, from Commonwealth air forces. For example, by the end of the war, Royal Canadian Air Force personnel had contributed more than 30 squadrons to service with RAF formations; almost a quarter of Bomber Command's personnel were Canadian.^[10] Similarly, about nine percent of the personnel who served with the RAF in Europe and the Mediterranean were seconded from the Royal Australian Air Force.^[11] To these and other British Commonwealth personnel were later added thousands of men from other countries, including many who had fled from German-occupied Europe.

A defining period of the RAF's existence came during the Battle of Britain. Over the summer of 1940 the RAF held off the Luftwaffe in perhaps the most prolonged and complicated air campaign in history. This arguably contributed immensely to the delay and cancellation of German plans for an invasion of the United Kingdom (Operation Sea Lion). Of these few hundred RAF fighter pilots, Prime Minister Winston Churchill famously said in the House of Commons on August 20, "Never in the field of human conflict was so much owed by so many to so few".^[12] Although, he first spoke these words upon exiting the Battle of Britain Bunker at RAF Uxbridge on August 16. However, in recent years some military historians have controversially suggested that the RAF's actions would not have prevented an invasion and that key deterrent was the Royal Navy's command of the sea.^[13]

The main RAF effort during the war was the strategic bombing campaign against Germany. From May 31, 1942 RAF Bomber Command was able to mount large-scale night raids, sometimes involving up to 1,000 aircraft. From mid-1942 increasing numbers of these aircraft were heavy four-engined bombers such as the Handley-Page Halifax and the Avro Lancaster. Noteworthy raids include Operation Millennium against Cologne, the first 1000-bomber raid; Operation Chastise, the 'Dambusters' raids on targets in the Ruhr Valley; Operation Gomorrah, the destruction of Hamburg; and the 'Battle of Berlin'. The lighter, fast two-engine de Havilland Mosquito fighter-bomber was used for tactical raids like Operation Carthage, a raid on the Gestapo headquarters in Copenhagen, as well as a night-fighter. The value of this campaign to the allied war effort has been disputed and it can be argued that it was a diversion or resources away from other vital areas - regardless of its moral implications.

There exists considerable historical controversy about the ethics of large-scale firebombing attacks against German cities during the last few months of the war, such as the bombing of Dresden, the bombing of Pforzheim, the bombing of Heilbronn and other German cities.

  1948 Arab–Israeli War

Following the end of the British Mandate of Palestine, the State of Israel was founded on 14 May 1948. Egyptian forces crossed into Israeli territory as part of a wider Arab League military coalition, with the Royal Egyptian Air Force providing light bombers as well as Spitfires. On 22 May, the Egyptians attacked RAF Ramat David, believing the base had already been taken over by Israeli forces. Two Royal Egyptian Air Force Spitfire LF.IXs strafed RAF Spitfire FR.XVIIIs of No. 32 Squadron and No. 208 Squadron on the ground. Flying Officers Geoff Cooper and Roy Bowie of 208 Squadron. then took off in their Spitfire FR.XVIIIs to mount a standing patrol. Three Egyptian Spitfire LF.IXs launched a second attack, two of which were shot down by Cooper and Bowie. Flying Officers McElhaw and Hully, also of 32 Squadron, took over the standing patrol before the third wave of Egyptian Spitfires arrived. Flying Officer McElhaw shot both of these down.^[14] The last Egyptian aircraft was baited for some time as the RAF pilots attempted to get a close look at its markings before it was destroyed.

  Cold War (1947–1990)

After victory in World War II, the RAF was to be further re-organized, as technological advances in air warfare saw the arrival of jet fighters and bombers. The first significant Cold War action of the RAF was its support to the Berlin Airlift in 1948 and 1949 which was originally designated Operation Knicker and Operation Carter-Paterson and later titled Operation Plainfare.

Although the United Kingdom did not base any RAF squadrons in Korea during the Korean War, several RAF pilots saw action while on exchange with the United States Air Force, mainly flying F-86 Sabres.^[15] They were credited with seven kills.^[16] Other RAF pilots flew Meteors in RAF squadrons on ground support attacks. Two flights of Army Cooperation aircraft flew in support of artillery spotting and reconnaissance. In addition, the two RAF squadrons of flying boats were based in Japan and flew maritime reconnaissance.^[17]

Before Britain developed its own nuclear weapons the RAF was provided with American nuclear weapons under Project E. After Britain developed its own nuclear weapons, the RAF's V bomber squadrons took sole responsibility for carrying the UK's nuclear deterrent until the development of the Royal Navy's Polaris submarines. Following the introduction of Polaris in 1968 the RAF's strategic nuclear role was reduced to a tactical one, using the WE.177 gravity bombs. This tactical role was continued by the V bombers into the 1980s and until 1998 by Tornado GR1s.

The primary role of the RAF in the Cold War years was the defence of Western Europe against potential attack by the Soviet Union, with many squadrons based in West Germany. With the decline of the British Empire, global operations were scaled back, and RAF Far East Air Force was disbanded on 31 October 1971.

Despite this, the RAF fought in many battles in the Cold War period. In June 1948 the RAF commenced Operation Firedog against Malayan terrorists during the Malayan Emergency. Operations continued for the next 12 years until 1960 with aircraft flying out of RAF Tengah and RAF Butterworth. The RAF played a minor role in the Korean War, with flying boats taking part. From 1953 to 1956 the RAF Avro Lincoln squadrons carried out anti-Mau Mau operations in Kenya using its base at RAF Eastleigh. The Suez Crisis in 1956 saw a large RAF role, with aircraft operating from RAF Akrotiri and RAF Nicosia on Cyprus and RAF Luqa and RAF Hal Far on Malta as part of Operation Musketeer. The Konfrontasi against Indonesia in the early 1960s did see use of RAF aircraft, but due to a combination of deft diplomacy and selective ignoring of certain events by both sides, it never developed into a full scale war.

  Falklands War

The Falklands War in 1982 was mainly fought by the Navy and Army due to the distance of the battlefield from friendly airfields. However RAF aircraft were deployed in the mid-Atlantic at RAF Ascension Island and on board the Navy's aircraft carriers alongside aircraft of the Fleet Air Arm. A detachment from No. 1 Squadron was deployed to the British Fleet during the War, operating from HMS Hermes and flying ground attack missions against Argentine forces.^[18][19] RAF pilots also flew Royal Navy Sea Harriers in the air-to-air combat role and four RAF pilots shot down five Argentine aircraft.^[20]

The most high profile RAF missions in this conflict were the famous Black Buck raids using Avro Vulcans flying from Ascension Island. However, the Service did many other things during the conflict, with its helicopters in the Falklands themselves, its Harrier GR3s flying from HMS Hermes, its fighter aircraft protecting Ascension, Nimrod MR2 maritime patrol aircraft scanning the South Atlantic, and tanker and transport fleet helping in the enormous logistical effort required for the war.

After the war the RAF remained in the South Atlantic to provide air defence to the Falkland Islands. The mid-Atlantic base on Ascension Island continued to be used as a staging post for the air bridge between the Great Britain and the Falkland Islands. In 1984 RAF Mount Pleasant was built to provide a fighter and transport facility on the islands thereby strengthening the defence capacity of the British Forces. Various radar sites were established and a detachment of the RAF Regiment provided anti-aircraft support until that role was transferred to the Royal Artillery. In 2009 the air defence F3s were replaced by four Typhoons which are based at RAF Mount Pleasant.^[21]

  1990–present

  Gulf War

During the build-up to the Gulf War, RAF fighters were based in Saudi Arabia and Kuwait. On 17 January 1991, the main air campaign began and over 100 RAF aircraft took part in virtually every conceivable role. It marked an important turning point in the RAF's history as it was the first time the service had used precision-guided munitions in significant amounts. In the years following the end of the war, the RAF were involved in operations to enforce the no-fly zones over Iraq.

  Afghanistan

As part of the British contribution (codenamed Operation Veritas) to the 2001 invasion of Afghanistan, the RAF provided support to the United States by operating air-to-air refuelling tankers and reconnaissance aircraft as well as proving the use of its bases. Chinook helicopters have provided airlift support to coalition forces. In late 2004, as part of Operation Herrick, RAF Harriers were based at Kandahar Airfield in Afghanistan, operating in the close air support role against the Taliban. The Harriers were replaced by an equivalent force of Tornados GR4 in spring 2009.^[22]

  Iraq War

The 2003 invasion of Iraq saw a large RAF deployment to the Gulf, including RAF strike aircraft. The RAF also staged the base for the 4 US B-52 Bombers which attacked Iraq almost every night. The only RAF losses were a friendly fire incident when an RAF Tornado jet was shot down by a US Patriot missile killing both pilot and Weapons Systems Operator due to the Patriot missile mistakenly recognising the Tornado as a Mig, and a Hercules transport plane shot down by ground fire killing the ten personnel on board just after take off from the US controlled airfield. Following the invasion occupation of southern Iraq by British Forces, the RAF was deployed at Basra. Currently, as part of Operation Telic, Merlin, Puma and Chinook helicopters operate from Basrah, protected by the RAF Regiment, forming 903 Expeditionary Air Wing.^[23] RAF operations in Iraq ended in 2009.

  Other operations and activities

In 1993, RAF Tornado F3s and AWACS aircraft contributed to Operation Deny Flight, NATO's operation to restrict airspace movements over Bosnia and Herzegovina. The operation continued until late 1995. Since that time, RAF helicopters have remained in Bosnia to provide support to the United Nations.

The Kosovo War in 1999 saw the RAF fight over Europe for the first time since World War II. During the bombing of Yugoslavia, the RAF operated the Harrier GR7 and Tornado ground attack jets as well as an array of support aircraft.

In 2004, four RAF Panavia Tornado F.3s deployed to the Baltic States for three months to provide the British contribution to the NATO-led Baltic Air Policing operation^[24] and in 2005 support and transport aircraft were dispatched to South East Asia following the 2004 Indian Ocean earthquake disaster in order to provide aid relief support.

The RAF's 90th anniversary was commemorated on 1 April 2008 by a flypast of 9 Red Arrows and 4 Typhoons along the Thames, in a straight line from just south of London City Airport Tower Bridge, the London Eye, the RAF Memorial and (at 13.00) the Ministry of Defence building.^[25][26][27]

  Number of personnel

Following the end of World War I, the RAF was greatly reduced in size and only rebuilt in significant number in the years immediately pre-ceding World War II. At its peak during World War II, there were over one million RAF servicemen. Following the demobilization after World War II, the RAF has steadily declined in numbers.
