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. The United States usually refers to Quick Reaction Alert as 'Airspace Control Alert'.
Some non-NATO countries maintain a QRA, either full-time or part-time.




Operation






= QRA in the United Kingdom

=
There are two QRA stations in the United Kingdom, one at RAF Coningsby in the east of England, and the other at RAF Lossiemouth in Scotland.
Pilots and engineers on QRA duty are at immediate readiness twenty-four hours a day. They are 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 maintained at readiness, along with a Voyager tanker at RAF Brize Norton in Oxfordshire. Before 2014 this task was carried out by a TriStar.

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

Swanwick, Hampshire with the London Area Control Centre and London Terminal Control Centre (at RAF West Drayton until 2007), broadly known as the London Air Traffic Control Centre, which covers the London Flight Information Region (EGTT). The RAF have a team at Swanwick.
Prestwick, which covers the Scotland Flight Information Region (EGPX) which is north of the Solway Firth.

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

RRH Benbecula in the Outer Hebrides
RRH Saxa Vord in Shetland (AN/TPS-77 radar moved from RRH Staxton Wold)
RRH Buchan (former Master Radar Station, or MRS, Buchan) off the A90 south of Peterhead
RRH Brizlee Wood in Hulne Park, Northumberland (west of RAF Boulmer)
RRH Staxton Wold off the B1249 in Willerby, North Yorkshire
RRH Neatishead at Neatishead, Norfolk
RRH Portreath in Cornwall
From 1997, the radars were the 1.1MW Plessey AR-320 (Type 93), and were replaced by the Lockheed Martin AN/FPS-117 system.

The United States refers to Quick Reaction Alert as Airspace Control Alert.




QRA response


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), in Denmark, watches Russian aircraft and can alert the UK, and has RAF staff there.
Russian Air Force Tupolev Tu-95 aircraft originate from the Olenya air base on the Kola Peninsula. Tupolev Tu-160 Blackjack aircraft come from the Engels-2 base near Saratov. The Tu-95 aircraft are on 12-14 hour missions, and when tracked across Norway have been colloquially referred to with the codename of zombies.
A QRA response involves the fighter aircraft being scrambled to investigate an infringement of the NATO country's airspace or area of interest.

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 Centre (CRC) at RAF Boulmer, which builds a 3D Recognised Air Picture. The National Air and Space Operations Centre (NASOC) at RAF Air Command, RAF High Wycombe decides whether to send a QRA response. The Joint Force Air Component Headquarters is also at High Wycombe.

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, which monitored the UK Air Defence Region (UK ADR). It was similar to the USA's and Canada's NORAD at Peterson Air Force Base. 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, with 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. When the Tornado F.3 arrived, the RAF QRA duty had an aircraft with complete night-vision capabilities and could connect to the Sentry aircraft.
In the 1960s, Southern Q was 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. In June 2007, 3 Sqn at RAF Coningsby took over Southern Q from the Tornados of 25 Sqn at RAF Leeming in North Yorkshire. The Typhoons of 3 Sqn had their first scramble in August 2007 when they intercepted a Russian Bear. 3 Sqn took over all of Southern Q from 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 September 2010, performing their first QRA scramble in January 2011. Typhoons joined 1 Sqn from 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 in September 2014. The first QRA sortie from Lossiemouth was on 19 September 2014 with 6 Sqn.
