GIUK gap
The GIUK gap (sometimes written G-I-UK) is an area in the northern Atlantic Ocean that forms a naval choke point. Its name is an acronym for Greenland, Iceland, and the United Kingdom, the gap being the two stretches of open ocean among these three landmasses. It separates the Norwegian Sea and the North Sea from the open Atlantic Ocean. The term is typically used in relation to military topics. The area has for some nations been considered strategically important since the beginning of the 20th century.
Since the beginning of the 20th century, the exploitation of the GIUK gap by northern forces and measures to patrol and secure the gap by opposing forces have played an important role in naval and in overall military planning.[citation needed]
From the start of World War II in 1939, German ships used the gap to break out from their bases in northern Germany (and from occupied Norway after April 1940) with a view to attacking Allied shipping convoys, but Allied blocking efforts in the North Sea and in the GIUK gap impeded such break-outs. British forces occupied the Faroe Islands in April 1940, and Iceland in May 1940; the United States took over effective control of Greenland in 1940. But the German Kriegsmarine profited greatly from the fall of France in June 1940, after which German submarines could operate from bases on the French coast.[citation needed]
The origin of the term "gap" dates to this period, when there was a gap in air coverage known as the Mid-Atlantic gap or the "Greenland air gap". This gap was an area that land-based aircraft could not reach and where, as a result, they could not carry out their anti-submarine duties.[citation needed]
The GIUK gap again became the focus of naval planning in the 1950s, as it represented the only available outlet into the Atlantic Ocean for Soviet submarines operating from their bases on the Kola Peninsula. NATO worried that if the Cold War "turned hot", naval convoys reinforcing Europe from the U.S. would suffer unacceptable losses if Soviet submarines could operate in the North Atlantic. The United States and Britain based much of their post-war naval strategy on blocking the gap, installing a chain of underwater listening posts right across it during the 1950s – an example of a SOSUS "sound surveillance system". This deployment of sonar surveillance in the gap, and elsewhere, hampered the Soviet Northern Fleet's ability to deploy its submarines without detection.
The Royal Navy's primary mission during the Cold War, excluding its nuclear deterrent role, involved anti-submarine warfare (ASW). The development of the Invincible-class ASW aircraft carriers stemmed from this doctrine: their primary mission involved anti-submarine warfare using Sea King helicopters. The Type 23 frigate originated as a pure ASW platform; its mission expanded following the Falklands War of 1982.[citation needed]
The largest Russian submarine drills through the GIUK gap were operations Aport and Atrina, in 1985 and 1987, respectively, when the Soviets deployed several SSNs near the U.S. coast before the 1985 Gorbachev–Reagan meeting.
The Soviets planned to use the GIUK gap to intercept any NATO ships, especially aircraft carriers, heading towards the Soviet Union. Ships and submarines as well as Tupolev Tu-142 maritime-surveillance aircraft aimed to track any threatening ships.[citation needed]
