In military aviation, scrambling is the act of quickly mobilising military aircraft. Scrambling can be in reaction to an immediate threat, usually to intercept hostile aircraft.
The term was used during the Battle of Britain, when Royal Air Force pilots and their fighters were readied and available to fly. Detection and monitoring of enemy aircraft, e.g. by the Chain Home radar stations, would feed into the RAF Fighter Command's Dowding system for control and management of the defenses. Once a decision had been made to intercept the enemy formation a telephone call would be made to the chosen fighter squadron's airfield, and those air crews available would be scrambled. The scramble order was communicated to alert pilots waiting by their aircraft by the loud ringing of a bell. [1] Every minute lost before takeoff would be advantageous to the enemy, as it could allow a pilot to gain extra height above the advancing plane formations. [2]
Information passed to the scrambling fighters included location and height: "Angels" with a number was used to describe height of aircraft, such as "Angels One Five" for aircraft approaching at 15,000 ft (4,600 m), and a rough estimate of numbers. Unidentified aircraft were known as bogeys , and known enemy ones were called bandits .
During the Cold War, many NATO air forces had crews stationed in Europe on alert and scrambled whenever their airspace was penetrated. The rudimentary bell-ringing communication was eventually replaced by electronic radio communication methods. However, many fighter squadrons into the current era would keep a bell at their squadron bar in legacy to the Battle of Britain roots. A common tradition was that anyone at the bar who rang the bell would be required to buy a round of drinks for all present.
Both interceptors and nuclear bomber forces were kept on "Quick Reaction Alert" (QRA). Crews were kept close to or in their aircraft positioned on Operational Readiness Platforms (ORP)'s at the runway, which were expected to be able to take off within a short period, such as 15 minutes, in less-than-normal situations. [3] It could be only two minutes at times of heightened tension between the opposing powers.
An interceptor aircraft, or simply interceptor, is a type of fighter aircraft designed specifically for the defensive interception role against an attacking enemy aircraft, particularly bombers and reconnaissance aircraft. Aircraft that are capable of being or are employed as both "standard" air superiority fighters and as interceptors are sometimes known as fighter-interceptors. There are two general classes of interceptor: light fighters, designed for high performance over short range; and heavy fighters, which are intended to operate over longer ranges, in contested airspace and adverse meteorological conditions. While the second type was exemplified historically by specialized night fighter and all-weather interceptor designs, the integration of mid-air refueling, satellite navigation, on-board radar, and beyond visual range (BVR) missile systems since the 1960s has allowed most frontline fighter designs to fill the roles once reserved for specialized night/all-weather fighters.
The Lockheed F-94 Starfire is a first-generation jet powered all-weather day/night interceptor aircraft designed and produced by Lockheed Corporation. It was the first operational United States Air Force (USAF) fighter equipped with an afterburner as well as being the first jet-powered all-weather fighter to enter combat during the Korean War.
Kincheloe Air Force Base was a United States Air Force (USAF) base during the Cold War. Built in the Upper Peninsula of Michigan in 1943 during World War II, the base was in service until 1977.
The McDonnell CF-101 Voodoo was an all-weather interceptor aircraft operated by the Royal Canadian Air Force and the Canadian Forces between 1961 and 1984. They were manufactured by the McDonnell Aircraft Corporation of St. Louis, Missouri for the United States Air Force, and later sold to Canada. CF-101s replaced the obsolete Avro CF-100 Canuck in the RCAF's all-weather fighter squadrons. The Voodoo's primary armament was nuclear AIR-2A Genie unguided air-to-air rockets, and there was significant political controversy in Canada about their adoption. Although they never fired a weapon in wartime, the CF-101 served as Canada's primary means of air defence from Quick Reaction Alert facilities at Canadian airbases. The CF-101s were retired in the 1980s and replaced with McDonnell Douglas CF-18 Hornet fighters. Many examples are preserved in museums and parks in Canada and the United States.
Ground-controlled interception (GCI) is an air defence tactic whereby one or more radar stations or other observational stations are linked to a command communications centre which guides interceptor aircraft to an airborne target. This tactic was pioneered during World War I by the London Air Defence Area organization, which became the Royal Air Force's Dowding system in World War II, the first national-scale system. The Luftwaffe introduced similar systems during the war, but most other combatants did not suffer the same threat of air attack and did not develop complex systems like these until the Cold War era.
Operation Sky Shield, properly Exercise Sky Shield, was a series of three large-scale military exercises conducted in the United States and Canada in 1960, 1961, and 1962 by NORAD Command and CONAD Command to test defenses against an air attack from the Soviet Union. The tests were intended to ensure that any attacks over the American–Canadian border or coastlines would be detected and then stopped.

In the armed forces, most often in military aviation and in land-based missile forces, an alert crew is a group of members of units and formations that maintains a group level of combat readiness. Although it sometimes encompasses the entire unit, today the term is more used for a set group of individuals.
On 25 May 1982, a Royal Air Force SEPECAT Jaguar of 14 Squadron, while returning to its base at RAF Brüggen in Germany following a training mission, was accidentally hit by an air-to-air missile fired by another Royal Air Force aircraft, a McDonnell Douglas Phantom. As a result, the Jaguar crashed in farmland approximately 35 miles from its base, although the pilot was able to eject safely.
