Bluie West One, later known as Narsarsuaq Air Base and Narsarsuaq Airport, was built on a glacial moraine at what is now the village of Narsarsuaq, near the southern tip of Greenland. Construction by the United States Army began in June 1941. The first aircraft landed there in January 1942, as a link in the North Atlantic air ferry route in World War II. The base had a peak population of about 4,000 American servicemen, and it is estimated that some 10,000 aircraft landed there en route to the war in Europe and North Africa.

Narsarsuaq Airport is an airport located in Narsarsuaq, a settlement in the Kujalleq municipality in southern Greenland. Along with Kangerlussuaq Airport, it is one of two airports in Greenland capable of serving large airliners. It is also the only international airport in southern Greenland. The settlement it serves is small, with the airport primarily functioning as a transfer point for passengers heading for the helicopter hubs of Air Greenland in Qaqortoq and Nanortalik. The airport is to be closed in 2025 when Qaqortoq Airport is scheduled to open.
