The site is located {{convert|60|mi|abbr=on}} north of the Arctic Circle and {{convert|90|mi|abbr=on}} from the northeast end of Kangerlussuaq Fjord, formerly known by its Danish name Søndre Strømfjord. The base is approximately {{convert|11|mi|abbr=on}} west-northwest of Ravneklippen and {{convert|80|mi|abbr=on}} east of Sisimiut. Following World War II, the base was briefly returned to Danish control between 9 October 1950 and 20 July 1951. The 1951 Greenland bases treaty led to the return of Sondrestrom to American control. The base was turned over to the Greenland government in 1992 and is now a civilian community (Kangerlussuaq) and airport (Kangerlussuaq Airport), although the USAF operates a small Air National Guard detachment in the former base.

Founding and ConstructionFollowing the fall of Denmark to Germany in World War II, responsibility for the security of Greenland passed to the American military under the terms of a 9 April 1941 treaty with the defected Danish ambassador in Washington. Military leaders responded by building several bases in Greenland, the largest of which were Bluie West One in Narsarsuaq in southern Greenland and Bluie West Eight along the Kangerlussuaq fjord. The site of BW-8 had already been contemplated for an airfield, and Professor William Hobbs of the University of Michigan had operated a meteorological station there in 1927-28. That station was named Mount Evans, while the supporting base camp at the site of the present seaport was named Camp Lloyd. A 1,500 foot long dirt airstrip eight miles east was prepared for the expected aircraft of Atlantic flyers Bert Hassell and Parker Cramer. They, however, ran out of fuel and walked the remaining distance to Sondrestrom. The location at the bottom of Sondrestromfjord is about as far from the coast as one can get on land in Greenland, and though the climate is severe, it is much more favorable for aviation than the coast. The approaches are clear, although the runway has a slope. During August 1940, the U.S. Coast Guard Cutter {{USCGC|Duane|WPG-33|2}} supported an aerial survey commanded by Army Captain Julius K. Lacey. From Lacey's Curtiss SOC-4, numerous photographs were obtained of promising runway alignments in the area. From 6 to 11 May 1941, the South Greenland Survey Expedition led by Lt. Cdr. William E. Sinton further examined the area from the {{USCGC|Northland|WPG-49|6}}, which now carried the same SOC-4 for aerial surveys. Charts and plans were drawn up in expectation of a major construction expedition that fall. The expedition also charted seaplane operating sites at Monroe Bay (Tatsip Ata) and Angujartorfik downfjords from Sondrestrom. Bluie West-8 was founded on 7 October 1941 by a 31-man expedition commanded by Captain (later Colonel) Bernt Balchen of the United States Army Air Forces (USAAF). A major sealift followed. The airport was ready for operation in the spring of 1942. A road of about ten miles length connected the airfield site with the port location (Camp Lloyd) farther down the fjord. Seasonal access for ships is during late summer and early autumn, but during the early days the fjord ice was broken for a much longer period. To identify and guide the approach to BW-8, an auxiliary station was placed at Cruncher Island, also known as Simiutak, at the entrance to Sondrestromfjord. This station, operational 4 September 1942, provided meteorological reports, radio communications, radio beacon and lights for air and sea traffic. It was known as BW-9. OperationsBW-8 was intended as a link in a northern air ferry route known to U.S. planners as the Crimson Route, but it transpired that few aircraft were ferried to Europe through it. Instead, the base earned its keep as an alternate field, a radio and weather reporting station, and as a departure point for search-and-rescue operations elsewhere in Greenland. During the two years Colonel Balchen was in command, he led numerous expeditions throughout the island, primarily in rescue operations for downed aircrew. As a reliever for the Greenland Command headquarters base in Narsarsuaq, Bluie West One, BW-8 was by late 1942 assisted by small fields at Bluie East Two in East Greenland, and Teague Field on the west coast about midways between BW-8 and BW-1. The Danish government briefly controlled the base in 1950, but following a renewed base treaty (also resulting in the construction of Thule Air Base), the United States reopened BW-8 under the name of Sondrestrom Air Base on 27 April 1951. Sondrestrom AB then became instrumental in the airlift to build Thule AB, although it had little function of its own, and rarely had permanently stationed aircraft. However, the base also served to support air refueling tankers, and trans-Atlantic ferry flights for short-ranged jet fighters continued to transit in the post-war period. When the Distant Early Warning Line was constructed in the late 1950s and early 1960s, Sondrestrom AB received a new lease on life. It assisted especially in the building of the four radar stations spanning Greenland (DYE-1 through 4). In the mid-1950s, Scandinavian Airlines System (SAS) began using the base as a refueling station on their then-new "Polar route" between Scandinavia and the United States. In 1956, SAS was operating three round trip flights a week with Douglas DC-6B propliners on a routing of Copenhagen - Sondrestrom - Winnipeg - Los Angeles.[1] This use fell off in the 1960s as airliners gained greater range. However, in the 1970s Boeing 707 jetliners operated by Dan-Air between the United Kingdom and Vancouver stopped to refuel. The base also became the hub of Greenland air traffic and was the destination for almost all regular air service from and to Copenhagen. The United States Air Force continued to use the base for occasional traffic, and in particular for the yearly resupply of the DYE stations. It was also a center for seasonal scientific activity. Following the fall of the Soviet Union and the abandonment of the DYE stations in 1991, the usefulness of the base was greatly diminished. The last US Air Force personnel left the base on 30 September 1992. It then became Kangerlussuaq airport, still the main hub for Greenland air travel. Rocket launchesSince 1971, rockets such as the Nike Apache, Petrel, Nike Tomahawk, Black Brant, Terrier Malemute, Taurus Orion, and Taurus Nike Tomahawk TNT have been launched from a site close to Kangerlussuaq (specifically, at {{Coord|67|01|23|N|050|35|49|W|type:airport|display=inline|name=Kangerlussuaq rocket launches}}) for examination of the upper atmosphere.[2] Launch List
