Keflavík (pronounced [ˈcʰɛplaˌviːk] ⓘ, meaning Driftwood Bay) is a town in the Reykjanes region in southwest Iceland.

[4] In the 1940s an airport was built next to the town by the United States military, which served as an important refueling stop for trans-Atlantic flights, especially during World War II.

During the Cold War, Naval Air Station Keflavik played an important role in monitoring marine and submarine traffic from the Norwegian and Greenland seas into the Atlantic Ocean.

The former NATO military base Naval Air Station Keflavik is used as a setting for an important story line in Tom Clancy's novel Red Storm Rising.

NAS Keflavik is also a central setting in Icelandic writer Arnaldur Indriðason's 1999 mystery Napóleonsskjölin, translated into English in 2011 as Operation Napoleon.
