GLOBUS is a radar system in the town of Vardø in Vardø Municipality, Finnmark county, Norway. It is operated by the Norwegian Intelligence Service (NIS) and its official uses are primarily space observation and Arctic airspace monitoring for Norway's national interest, though the site's close proximity to known Russian naval bases as well as U.S. involvement in construction and funding have fueled suspicions that it also serves as part of an American missile defense system.
