Quick Reaction Alert (QRA) is state of readiness and modus operandi of air defence maintained at all hours of the day by NATO air forces.

Some non-NATO countries like Switzerland,[1] also maintain QRA, although not all, like Austria, necessarily full-time.[2][3]

QRA in the United Kingdom[edit]

Pilots and engineers on QRA duty are at immediate readiness twenty-four hours a day fully dressed in the Crew Ready Room, which are next to the hangars (a hardened aircraft shelter known informally as Q-sheds) which houses the interceptor aircraft, since 2007 the Eurofighter Typhoon. Pilots are on QRA duty around once or twice a month, each a twenty-four-hour shift. Engineers are on QRA duty three or four times a year, each for a twenty-four-hour a day shift for seven days at a time. Two Typhoon aircraft are on duty, along with an Voyager tanker at RAF Brize Norton in Oxfordshire; before 2014 this was carried out by a TriStar.

Civilian aircraft in the UK are monitored by NATS Holdings at:

RRH Staxton Wold in May 2009; Staxton Wold is possibly the oldest operational radar station in the world

Military radar in the UK is controlled by the UK Air Surveillance and Control System (ASACS),[4] looked after by ASACS Force Command.[5] It has Remote Radar Heads (RRH) at:

The radars were Type 93, and are being replaced by the Lockheed Martin AN/FPS-117 system.

QRA response[edit]

Air traffic across Europe is controlled by Eurocontrol in Brussels. Military aircraft from Russia can be tracked across Norway, and reported to the Norwegian Joint Headquarters near Bodø, or the Combined Air Operations Centre 2 (CAOC UE) in Uedem, North Rhine-Westphalia close to the border with The Netherlands. Combined Air Operations Centre Finderup (CAOC Finderup),[6] in Denmark, watches Russian aircraft and can alert the UK, and has RAF staff there. The Russian Tu-95 Bear aircraft originate from the Olenya base on the Kola Peninsula and the Tu-160 Blackjack aircraft come from the Engels-2 base near Saratov. The Bear aircraft are on 12-14 hour missions, and when tracked across Norway have been colloquially referred to with the codename of zombies.[citation needed]

A QRA response involves the fighter aircraft being scrambled to investigate an infringement of the NATO country's airspace or area of interest.

QRA response in the United Kingdom[edit]

This may also be a civilian aircraft that poses a threat, if not sufficiently responding to air traffic control (ATC); incidents of this nature in the UK are monitored by the Control and Reporting Centres (CRC) at RAF Boulmer and RAF Scampton, which builds a 3D Recognised Air Picture and the National Air Defence Operations Centre (NADOC) RAF Air Command, if notified, decides whether to send a QRA response. Joint Force Air Component Headquarters is also at High Wycombe.

QRA stations[edit]


Graf Ignatievo Air Base (3rd Fighter Air Base) of the BuAF has a single MiG-29 squadron, which carry two R-73 missiles. the Bulgarian CRC is at Sofia.


At Grosseto Air Base, in the Province of Grosseto on the west Italian coast, the Typhoon is operated by IX Gruppo of 4º Stormo Caccia, at Trapani-Birgi Airport, in Sicily, by 18° Gruppo of 37° Stormo, at Gioia del Colle Air Base, Apulia, by 10° Gruppo and 12° Gruppo of 36º Stormo and at Istrana Air Base, Veneto, by the 51° Stormo. At Amendola Air Base F-35 is operated by 13° Gruppo of 32° Stormo.


The Royal Netherlands Air Force have F-16 aircraft at Volkel Air Base or Leeuwarden Air Base on high alert. They intercept once notified by the Air Operations Control Station Nieuw-Milligen, near Apeldoorn in Gelderland. The Royal Netherlands Air Force shares the responsibilities for QRA above Benelux with the Belgian Air Component since 2016/2017.


The RoAF 71st Air Base (Baza 71 Aeriană) at Câmpia Turzii in central Romania and the RoAF 86th Air Base (Baza 86 Aeriană) at Borcea in south-east Romania both operate the MiG-21 LanceRs, which carry the Matra Magic 2 missile. The Romanian CRC is at Balotești in southern Romania.


At the Morón Air Base at Morón de la Frontera in the Province of Seville in the south of Spain, Ala 11 (11th Wing) has three squadrons of Typhoons, with 111 Sqn and 112 Sqn. Los Llanos Air Base has 141 Sqn and 142 Sqn of Ala 14.


Merzifon Air Base of the TuAF (Türk Hava Kuvvetleri), in northern Turkey, has two F-16 squadrons (built by TAI) with the 5th Air Wing (5 Ana Jet Üs). Bandırma Air Base has two F-16 squadrons of the 6th Air Wing. The Turkish CRC is at Ahlatlabel near Ankara.

United Kingdom[edit]

Currently there are two QRA RAF stations, of 1 Group.


Quick Reaction Alert is the current development from scrambling by RAF Fighter Command in the Battle of Britain.


RAF Wildenrath provided air defence cover for Royal Air Force Germany (RAFG), which flew Phantoms with 92 Sqn and 19 Sqn until 1991. On 25 May 1982, RAF Phantom XV422 of 92 Sqn shot down RAF Jaguar XX963 of 14 Sqn from RAF Bruggen with a Sidewinder, over Germany, by mistake when the Phantom pilot did not realise that he was fully armed.[8]


The first country to put the Typhoon onto QRA duty was Italy on 16 December 2005, by IX Gruppo of 4º Stormo; 12° Gruppo of 36º Stormo followed on 1 July 2007 and 10° Gruppo on 1 July 2010. Typhoons replaced the F-16A/ADF of 37° Stormo at Trapani from May 2012. From 1 March 2018 the F-35 of 32° Stormo based in Amendola, has implemented the QRA assets.


111 Sqn put the first Typhoon on QRA duty in July 2008, followed by 142 Sqn of Ala 14, and later 141 Sqn.

United Kingdom[edit]

In the 1950s and 1960s, training as a fighter controller in the UK was at MRS Bawdsey (RAF Bawdsey); the main central control was known as ADOC (similar to the USA's and Canada's NORAD at Peterson Air Force Base) which monitored the UK Air Defence Region (UK ADR). The ROTOR system was developed in the 1950s. Before computers arrived in the 1970s, the Russian aircraft were plotted on a map, mainly by WRAF personnel. 11 Group (at RAF Bentley Priory from 1968 and RAF High Wycombe from 1972) looked after the UK's air defence until the 1990s; High Wycombe today has the European Air Group.

Every QRA alert required a Victor tanker from RAF Marham in Norfolk, which the codename Dragonfly. One fighter squadron would be on QRA for six month shifts. The Phantom had much better range than the Lightning, and had far-better look down radar, but the Lightning had better performance. The RAF Phantom variant had Spey engines, which were not intentionally designed for the aircraft, and gave lower performance; it had an advanced jam-resistant inertial navigation system but the RAF Phantoms could not take off immediately as this inertial system had to align first. The Lightning left service in 1988 and the Phantom in 1992. Only when the Tornado F.3 arrived did RAF QRA duty have an aircraft that had complete night-vision capabilities and could connect to the Sentry aircraft.

In the 1960s, Southern Q was at maintained by the Lightnings of 5 Sqn at RAF Binbrook and those of 29 Sqn and 111 Squadron at RAF Wattisham. Southern Q was rotated around the three RAF bases. RAF Leeming took over Southern Q from RAF Coningsby in 1988. 11 Sqn left RAF Leeming in October 2005,[9] then on 29 June 2007, 3 Sqn at RAF Coningsby took over Southern Q from the Tornados of 25 Sqn at RAF Leeming in North Yorkshire, with the Typhoons of 3 Sqn having their first scramble on 17 August 2007 when they intercepted a Russian Bear; 3 Sqn took over all of Southern Q from 1 April 2008. In August 2007 the Russians had begun to launch long-distance patrols after a 15-year hiatus. Typhoons arrived at RAF Leuchars with 6 Sqn from 6 September 2010, performing their first QRA scramble on 2 January 2011, with Typhoons joining 1 Sqn from 15 September 2012. 6 Sqn moved to Lossiemouth in June 2014, with 1 Sqn moving in August 2014. QRA North was moved from RAF Leuchars to RAF Lossiemouth on 1 September 2014. The first QRA sortie from Lossiemouth was on 19 September 2014 with 6 Sqn.

2012 Olympics[edit]

To cover the security for the 2012 Summer Olympics, part of QRA South was briefly deployed from RAF Coningsby to operate from RAF Northolt.
