The RAF's mission is to support the objectives of the British Ministry of Defence (MoD), which are to "provide the capabilities needed: to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government’s foreign policy objectives particularly in promoting international peace and security." The RAF describe its mission statement as "... [to provide] An agile, adaptable and capable Air Force that, person for person, is second to none, and that makes a decisive air power contribution in support of the UK Defence Mission." The mission statement is supported by the RAF's definition of air power, which guides its strategy. Air power is defined as: "The ability to project power from the air and space to influence the behaviour of people or the course of events."
While 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. It was founded on 1 April 1918, with headquarters located in the former Hotel Cecil, during the First World War, by the amalgamation of the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). At that time it was the largest air force in the world. After the war, the service was drastically cut and its inter-war years were relatively quiet, with the RAF taking responsibility for the control of Iraq and executing a number of minor actions in other parts of the British Empire. The RAF's naval aviation branch, the Fleet Air Arm, was founded in 1924 but handed over to Admiralty control on 24 May 1939.
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.
The Avro Lancaster heavy-bomber was extensively used during the strategic bombing of Germany.
In the Battle of Britain in 1940, the RAF (supplemented by 2 Fleet Air Arm Squadrons, Polish, Czech and other multinational pilots and ground personnel) defended the skies over Britain against the numerically superior German Luftwaffe. In what is perhaps the most prolonged and complicated air campaign in history, the Battle of Britain contributed significantly to the delay and subsequent indefinite postponement of Hitler's plans for an invasion of the United Kingdom (Operation Sealion). In the House of Commons on 20 August, prompted by the ongoing efforts of the RAF, Prime Minister Winston Churchill eloquently made a speech to the nation, where he said "Never in the field of human conflict was so much owed by so many to so few".
The largest RAF effort during the war was the strategic bombing campaign against Germany by Bomber Command. While RAF bombing of Germany began almost immediately upon the outbreak of war, under the leadership of Air Chief Marshal Harris, these attacks became increasingly devastating from 1942 onward as new technology and greater numbers of superior aircraft became available. The RAF adopted night-time area bombing on German cities such as Hamburg and Dresden, and developed precision bombing techniques for specific operations, such as the "Dambusters" raid by No. 617 Squadron, or the Amiens prison raid known as Operation Jericho.
Following victory in the Second World War, the RAF underwent significant re-organisation, as technological advances in air warfare saw the arrival of jet fighters and bombers. During the early stages of the Cold War, one of the first major operations undertook by the Royal Air Force was in 1948 and the Berlin Airlift, codenamed Operation Plainfire. Between 26 June and the lifting of the Russian blockade of the city on 2 May, the RAF provided 17% of the total supplies delivered during the event, using Avro Yorks, Douglas Dakotas flying to Gatow Airport and Short Sunderlands flying to Lake Havel.
Before Britain developed its own nuclear weapons the RAF was provided with American nuclear weapons under Project E. However following the development of its own arsenal, the British Government elected on 16 February 1960 to share the country's nuclear deterrent between the RAF and submarines of the Royal Navy, first deciding on 13 April to concentrate solely on the air force's V bomber fleet. These were initially armed with nuclear gravity bombs, later being equipped with the Blue Steel missile. Following the development of the Royal Navy's Polaris submarines, the strategic nuclear deterrent passed to the navy's submarines on 30 June 1969. With the introduction of Polaris, 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.
One of the largest actions undertook by the RAF during the cold war was the air campaign during the 1982 Falklands War, in which the RAF operated alongside the Fleet Air Arm. During the war, RAF aircraft were deployed in the mid-Atlantic at RAF Ascension Island and a detachment from No. 1 Squadron was deployed with the Royal Navy, operating from the aircraft carrier HMS Hermes. RAF pilots also flew missions using the Royal Navy's Sea Harriers in the air-to-air combat role. Following a British victory, the RAF remained in the South Atlantic to provide air defence to the Falkland Islands, based at RAF Mount Pleasant (built 1984).
In recent years fighter aircraft on Quick Reaction Alert (QRA) have been increasingly required to scramble in response to efforts made by the Russian Air Force to approach British airspace. On 24 January 2014 in the Houses of Parliament, Conservative MP and Minister of State for the Armed Forces, Andrew Robathan, announced that the RAF's QRA force had been scrambled almost thirty times in the last three years: eleven times during 2010, ten times during 2011 and eight times during 2012.
RAF Coningsby in Lincolnshire and RAF Leuchars in Fife both provide Quick Reaction Alert, or QRA, and scramble their fighter jets within minutes to meet or intercept aircraft which give cause for concern. Leuchars generally covers the northern sector, while Coningsby provides QRA in the south. Typhoon pilot Flight Lieutenant Noel Rees describes how QRA duty works. "At the start of the scaled QRA response, civilian air traffic controllers might see on their screens an aircraft behaving erratically, not responding to their radio calls, or note that it’s transmitting a distress signal through its transponder. Rather than scramble Typhoons at the first hint of something abnormal, a controller has the option to put them on a higher level of alert, ‘a call to cockpit’. In this scenario the pilot races to the hardened aircraft shelter and does everything short of starting his engines."
Authority is delegated from the Air Force Board to the RAF's command. While there were once individual commands responsible for bombers, fighters, training, etc., now only the Air Command exists, headquartered at RAF High Wycombe.
An RAF station is ordinarily subordinate to a group and it is administratively sub-divided into wings. Since the mid to late 1930s RAF stations have controlled a number of flying squadrons or other units at one location by means of a station headquarters.
A wing is either an operational sub-division of a group or an administrative sub-division of an RAF station.
Independent Wings are a grouping of two or more squadrons, either flying squadrons or ground support squadrons. In former times, numbered flying wings have existed, but recently they have been created only when required. For example during Operation Telic, Tornado GR4 wings were formed to operate from Ali Al Salem and Al Udeid air bases and the Tornado F3 equipped Leuchars Fighter Wing at Prince Sultan Air Base; each of these were made up of aircraft and crews from several squadrons.
On 31 March 2006, the RAF formed nine Expeditionary Air Wings (EAWs) to support operations. They were established at the nine main operating bases; RAF Coningsby, RAF Cottesmore, RAF Kinloss, RAF Leeming, RAF Leuchars, RAF Lossiemouth, RAF Lyneham, RAF Marham and RAF Waddington numbered Nos 121, 122, 325, 135, 125, 140, 38, 138 and 34 EAWs respectively. These units are commanded by a Group Captain who is also the parent unit's Station Commander. The EAW comprises the non-formed unit elements of the station that are required to support a deployed operating base, i.e. the command and control, logistics and administration functions amongst others. They are designed to be flexible and quickly adaptable for differing operations. They are independent of flying squadrons, Air Combat Support Units (ACSU) and Air Combat Service Support Units (ACSSU) who are attached to the EAW depending on the task it has been assigned.
A wing is also an administrative sub-division of an RAF station. Historically, for a flying station these were normally Operations Wing, Engineering Wing and Administration Wing and each wing was commanded by an officer of wing commander rank. Early in the 21st century, the model changed, with Engineering Wing typically being split into Forward Support Wing and Depth Support Wing, while Administration Wing was redesignated Base Support Wing.
A flying squadron is an aircraft unit which carries out the primary tasks of the RAF. RAF squadrons are somewhat analogous to the regiments of the British Army in that they have histories and traditions going back to their formation, regardless of where they are based, which aircraft they are operating, etc. They can be awarded standards and battle honours for meritorious service. Whilst every squadron is different, most flying squadrons are commanded by a wing commander and, for a fast-jet squadron, have an establishment of around 100 personnel and 12 aircraft.
The term squadron can be used to refer to a sub-unit of an administrative wing or small RAF station, e.g. Air Traffic Control Squadron, Personnel Management Squadron etc. There are also Ground Support Squadrons, e.g. No 2 (Mechanical Transport) Squadron which is located at RAF Wittering. Administrative squadrons are normally commanded by a squadron leader.
A flight is a sub-division of a squadron. Flying squadrons are often divided into two flights, e.g. "A" and "B", each under the command of a squadron leader. Administrative squadrons on a station are also divided into flights and these flights are commanded by a junior officer, often a flight lieutenant. Because of their small size, there are several flying units formed as flights rather than squadrons. For example No. 1435 Flight is based at RAF Mount Pleasant in the Falkland Islands, maintaining air defence cover with four Eurofighter Typhoon aircraft.
At its height in 1944 during the Second World War, more than 1,100,000 personnel were serving in the RAF. The longest-lived founding member of the RAF was Henry Allingham, who died on 18 July 2009 aged 113.
As of 1 December 2013, the Royal Air Force numbered some 35,660 Regular and 1,540 Royal Auxiliary Air Force personnel, giving a combined component strength of 37,200 personnel. In addition to the active elements of the Royal Air Force, (Regular and Royal Auxiliary Air Force), all ex-Regular personnel remain liable to be recalled for duty in a time of need, this is known as the Regular Reserve. In 2007 there were 33,980 Regular Reserves of the Royal Air Force, of which 7,950 served under a fixed-term reserve contract. Publications since April 2013 no-longer report the entire strength of the Regular Reserve, instead they only give a figure for Regular Reserves who serve under a fixed-term reserve contract. They had a strength of 7,160 personnel in 2013.
Figures from 2010 showed that Royal Air Force pilots achieve a relatively high number of flying hours per year when compared with other major NATO allies such as France and Germany. RAF fast jet pilots achieve 210 flying hours per year, while RAF transport and aerial refuelling pilots achieve 290 flying hours per year. In addition, RAF pilots on transport and support helicopters achieve 240 flying hours per year. French and German Air Force pilots achieved only 180 and 150 flying hours across their fleets respectively.
Officers hold a commission from the Sovereign, which provides the legal authority for them to issue orders to subordinates. The commission of a regular officer is granted after successfully completing the 32-week-long Initial Officer Training course at the RAF College, Cranwell, Lincolnshire. Other officers also train at RAF Cranwell, but on different courses, such as those for professionally qualified officers.
The titles and insignia of other ranks in the RAF were based on that of the Army, with some alterations in terminology. Over the years, this structure has seen significant changes: for example, there was once a separate system for those in technical trades, and the ranks of Chief Technician and Junior Technician continue to be held only by personnel in technical trades. RAF other ranks fall into four categories: Warrant Officers, Senior Non-Commissioned Officers, Junior Non-Commissioned Officers and Airmen.
RAF Pilots and Weapon Systems Officers (WSO) (formerly known as Navigators) are commissioned officers of the Flying Branch. i.e. Fg(P) or Fg(WSO). Formerly in the General Duties branch, which is now reserved for Wing Commanders and above from any previous branch.
Non-commissioned (NCO) Aircrew known as Weapons System Operators (WSOp), fulfil the specialist roles of air engineer (E), air electronics operator (AEOp), air loadmaster (ALM) and air signaller (S). Though they are now known collectively as weapon systems operators, individual trade specialisations remain. Commissioned officer specialists are promoted from within branch to become Fg(WSO).
The majority of the members of the RAF serve in support roles on the ground.
Engineering Officers and technicians are employed to maintain and repair the equipment used by the RAF. This includes routine preparation for flight and maintenance on aircraft, arming aircraft with weapons, as well as deeper level repair work on aircraft systems, IT systems, ground based radar, vehicles, ground support equipment, etc.
RAF Flight Operations Officers are involved with the planning and co-ordination of all Flying Operations. Flight Operations Officers can be found in every RAF Flying Station and Squadron.
The RAF Regiment is the RAF's infantry unit, its officers and gunners defend RAF airfields from attack. The RAF Regiment is also responsible for CBRN defence and training the rest of the RAF in ground defence.
Aerospace Battle Managers (formally Fighter Controllers/FC) and Air Traffic Controllers (ATC), control RAF and NATO aircraft from the ground. The FC control the interception of enemy aircraft while the ATC provide air traffic services at RAF stations and to the majority of en-route military aircraft in UK airspace.
RAF Intelligence Officers and Intelligence Analysts support all operational activities by providing timely and accurate indicators and warnings. They conduct detailed all source military intelligence fusion and analysis by utilising classified and open source information including imagery, human and communications (signals) intelligence. Intelligence is used to inform commanders of the assessed capabilities and intentions of the enemy for strategic / operational planning and targeting. They also tailor the information to brief aircrews for mission planning and other tactical units (such as RAF Regiment) for Force Protection.
RAF Medical Branch provides healthcare at home and on deployed operations, including aeromedical evacuation services. Medical officers are the doctors of the RAF and have specialist expertise in aviation medicine to support aircrew and their protective equipment. Medical officers can go on aeromedical evacuations, providing vital assistance on search-and-rescue missions or emergency relief flights worldwide. RAF Medical Officers are either based in primary care on operations or on RAF stations in the UK or in one of six Ministry of Defence Hospital Units (MDHU's) around the UK as specialist practitioners.
Administrative Officers and associated Pers Admin trades are involved with human resources management, training management, physical education, catering, infrastructure management, accounts, dress and discipline, personnel and recruitment.
British military aircraft designations generally comprise a type name followed by a mark number which includes an alphabetical rôle prefix. For example, the now retired Tornado F3 was designated as a fighter by the 'F', and the third variant of the type to be produced.
Airborne early warning and reconnaissance aircraft
The Sentry AEW1, based at RAF Waddington, provides airborne early warning to detect incoming enemy aircraft and to co-ordinate the aerial battlefield. The Sentinel R1 (also known as ASTOR – Airborne STand-Off Radar) provides a ground radar-surveillance platform based on the Bombardier Global Express long range business jet. These were supplemented in 2009 by four Beechcraft Shadow R1 aircraft equipped for the ISTAR role over Afghanistan. The Tornado GR4A is fitted with cameras and sensors in the visual, infra-red and radar ranges of the spectrum.
An important part of the work of the RAF is to support the British Army by ferrying troops and equipment at the battlefield. However, RAF helicopters are also used in a variety of other roles, including support of RAF ground units and heavy-lift support for the Royal Marines. The support helicopters are organised into the tri-service Joint Helicopter Command (JHC), along with helicopters of the British Army and Royal Navy. The only helicopters not coordinated by the JHC are the search and rescue helicopters of the RAF and RN, and those RN helicopters that are normally based on board a ship such as a destroyer or frigate.
The RAF operate the C-17 Globemaster III in the heavy strategic airlift role, originally leasing four from Boeing. These were purchased, followed by a fifth delivered on 7 April 2008 and a sixth delivered on 8 June 2008. The new aircraft entered frontline use within days rather than weeks. The MoD said there was "a stated departmental requirement for eight" C-17s and a seventh was subsequently ordered, to be delivered in December 2010. In February 2012 the purchase of an eighth C-17 was confirmed; the aircraft arrived at RAF Brize Norton in May 2012.
More routine strategic airlift transport tasks are carried out by the Airbus A330 MRTT, known as the Voyager in RAF service. The first Voyager arrived in the UK for testing at MoD Boscombe Down in April 2011, and entered service in April 2012. The Voyager received approval from the MoD on 16 May 2013 to begin air-to-air refuelling flights and made its first operational tanker flight on 20 May 2013 as part of a training sortie with Tornado GR4s. By 21 May 2013, the Voyager fleet had carried over 50,000 passengers and carried over 3,000 tons of cargo. A total of 14 Voyagers are due to form the fleet, with 9 allocated to sole RAF use. As the Voyagers lack a refueling boom, the RAF has requested a memorandum of understanding (MoU) with the USAF allowing the UK access to tankers equipped with refueling booms for its Boeing RC-135W AirseekerSIGINT aircraft.
Shorter range, tactical-airlift transport is provided by the Hercules, the fleet including both older C-130K (Hercules C1/C3) and newer C-130J (Hercules C4/C5) variants, based at RAF Brize Norton in Oxfordshire. All C-130s will be withdrawn by 2022.
No. 32 (The Royal) Squadron replaced the Queen's Flight in 1995 and operate the BAe 125 CC3, Agusta A109 and BAe 146 CC2 in the general air transport and VIP transport roles. The squadron is based at RAF Northolt in west London. Aircraft operate with a priority for military needs over VIP transport. Two additional BAe 146s were purchased in March 2012 from TNT Airways and were refitted by Hawker Beechcraft on behalf of BAE Systems for tactical freight and personnel transport use. The aircraft, designated as the BAe 146 C Mk 3, arrived in Afghanistan in April 2013.
Three squadrons of helicopters exist with the primary role of military search and rescue; the rescuing of aircrew who have ejected or crash-landed their aircraft. These are 22 Squadron and 202 Squadron with the Sea King HAR.3/HAR3A in the UK and 84 Squadron with the Griffin HAR2 in Cyprus. Although established with a primary role of military search and rescue, most of their operational missions are spent in their secondary role of conducting civil search and rescue; that is, the rescue of civilians from the sea, on mountainsides and other locations. Both rescue roles are shared with the Sea King helicopters of the Royal Navy's Fleet Air Arm, while the civil search and rescue role is also shared with the helicopters of HM Coastguard. The Operational Conversion Unit is 203 Squadron RAF based at RAF Valley equipped with the Sea King HAR3.
Elementary flying training is conducted on the Tutor T1. The Tutor is also used, along with the Viking T1 and Vigilant T1 gliders, to provide air experience training for air cadets and elementary flying training for trainee RAF pilots. Basic pilot training for fixed-wing and helicopter pilots is provided on the Tucano T1 and Squirrel HT1. Weapon systems officer and weapon systems operator training was conducted in the Dominie T1 until the decommissioning of the last six Dominie T1 in January 2011. Advanced flying training for fast-jet, helicopter and multi-engine pilots is provided using the Hawk T1, Griffin HT1 and B200 King Air respectively. At the more advanced stage in training, variants of front-line aircraft have been adapted for operational conversion of trained pilots, such as the Typhoon T1.
The Airbus A400M will replace the RAF's fleet of Hercules C1/C3 (C-130K) transport aircraft. Originally, 25 aircraft were ordered, although the total is now 22. The A400M will be known as the Atlas in RAF service.
Three Boeing RC-135W Rivet Joint have been ordered to replace the Nimrod R1 fleet in the signals intelligence role in 2014. The Nimrod fleet was retired in 2011, and the RAF will share signals aircraft of the US Air Force until the RC-135s enter service. The aircraft will be Boeing KC-135 Stratotanker tankers converted to RC-135W standard in the most complex combined Foreign Military Sales case and co-operative support arrangement that the UK has undertaken with the United States Air Force since the Second World War. In RAF service, they will be known as the Airseeker.
The F-35B Lightning II is intended to enter service around 2020 under the Joint Combat Aircraft programme. Although the Short Take Off Vertical Landing (STOVL) F-35B version had been selected initially, in October 2010, David Cameron announced that the UK would change their order to the F-35C CATOBARcarrier variant for both the RAF and Navy, citing greater range and the ability to carry a larger and more diverse payload than the F-35B. However, in May 2012, it was announced that the UK government had reverted to the previous government's plan to operate the F-35B STOVL variant, due to rising estimated shipbuilding costs associated with the F-35C, and an earlier estimated in-service date for the F-35B. On 19 July 2012 the Defence Secretary, Philip Hammond, in a speech in the USA, indicated that the UK would initially receive 48 F-35B and would announce at a later date what the final numbers would be. Jon Thompson, MOD Permanent Secretary, told the House of Commons Defence Select Committee, in late 2012: "Our commitment over the first 10 years is for 48 F-35B. "An order for the first 14 aircraft on top of the four already procured for operational test and evaluation is expected later in 2013. The F-35 is expected to replace the Eurofighter and become Britain's only manned jet fighter from 2030.
The BAE Mantis is another UCAV under development, with an autonomous capability, allowing it to fly itself through an entire mission. This is a potential candidate to fulfil a requirement for an ISTAR UAV to enter service after 2015 as part of the RAF's Scavenger programme.
Following the tradition of the other British fighting services, the RAF has adopted symbols to represent it, act as a rallying point for its members and encourage esprit de corps.
The RAF Ensign is flown from the flagstaff on every RAF station during daylight hours. The design was approved by King George V in 1921, after much opposition from the Admiralty, who have the right to approve or veto any flag flown ashore or on board ship.
British aircraft in the early stages of the First World War carried the Union Flag as an identifying feature, however this was easy to confuse with Germany's Iron Cross motif. Therefore in October 1914 the French system of three concentric rings was adopted, with the colours reversed to a red disc surrounded by a white ring and an outer blue ring. The relative sizes of the rings have changed over the years and during World War II an outer yellow ring was added. Aircraft serving in the Far East during World War II had the to prevent with Japanese aircraft. Since the 1970s, camouflaged aircraft carry low-visibility roundels, either red and blue on dark camouflage, or washed-out pink and light blue on light colours. Most uncamouflaged training and transport aircraft retain the traditional red-white-blue roundel.
The Latin motto of the RAF, "Per Ardua ad Astra", is usually translated as "Through Adversity to the Stars", but the RAF's official translation is "Through Struggle to the Stars". The choice of motto is attributed to a junior officer named J S Yule, in response to a request from a commander of the RFC, Colonel Sykes, for suggestions. The RAF inherited the motto from the RFC.
The Badge of the Royal Air Force was first used in August 1918. In heraldic terms it is: "In front of a circle inscribed with the motto Per Ardua Ad Astra and ensigned by the Imperial Crown an eagle volant and affronte Head lowered and to the sinister." Although there have been debates among airmen over the years whether the bird was originally meant to be an albatross or an eagle, the consensus is that it was always an eagle.
In 2006 the RAF adopted a logotype featuring a roundel and the Service's unabbreviated name (shown at the top of this article). The logotype is used on all correspondence and publicity material and aims to provide the Service with a single, universally recognisable brand identity.
The Red Arrows, officially known as the Royal Air Force Aerobatic Team, is the aerobatics display team of the Royal Air Force based at RAF Scampton, with under-review plans to move to RAF Waddington. The team was formed in late 1964 as an all-RAF team, replacing a number of unofficial teams that had been sponsored by RAF commands.
The Red Arrows badge shows the aircraft in their trademark Diamond Nine formation, with the motto Éclat, a French word meaning "brilliance" or "excellence".
Initially, they were equipped with seven Folland Gnat trainers inherited from the RAF Yellowjacks display team. This aircraft was chosen because it was less expensive to operate than front-line fighters. In their first season, they flew at 65 shows across Europe. In 1966, the team was increased to nine members, enabling them to develop their Diamond Nine formation. In late 1979, they switched to the BAE Hawk trainer. The Red Arrows have performed over 4,000 displays worldwide in 53 countries.
Headquarters Royal Air Force Music Services, located at RAF Northolt, supports 177 professional musicians who attend events around the globe in support of the RAF. RAF Music Services were established in 1921, although the first RAF Director of Music was appointed in 1918. The Music Services were expanded for World War II and in the post war years there were ten established bands. Since then, Music Services has gradually been reduced in size and today comprises:
After initial use of the Airport at Stanley, the airbase/airport at Mount Pleasant was built to allow a fighter and transport facility on the islands, and to strengthen the defence capacity of BFFI (British Forces Falkland Islands). BFFI now replaced by BFSAI (British Forces South Atlantic Islands).
Chinooks provided airlift support to coalition forces. Additionally Merlin helicopters began tasking in late 2009 following the end of Operation Telic (Iraq). Since late 2004 six BAe Harriers provided reconnaissance and close air support to the ISAF. The Harriers were replaced by an equivalent force of Tornado GR4 in mid-2009. In August 2010, the Tornado force was uplifted to 10 aircraft. Other support units are deployed to Muscat International Airport in Oman, and air bases in the UAE and the Kingdom of Bahrain.
During the initial invasion, British strike fighters were used. Support aircraft such as the Hercules C130, Puma helicopter and Merlin helicopter stayed in Iraq until the withdrawal in 2009. The Merlin helicopters were the last RAF aircraft to leave Iraq.
