The Iceland Air Defence System () was founded in 1987. It operates four radar complexes, a software and support facility as well as a command and report centre. , it does not independently possess any offensive capabilities, as Iceland's only air defence weaponry consists of a battery of surface-to-air defences which effectively deter aircraft, but is primarily used instead to monitor air traffic and direct allied interceptors based out of country. Between 2009-2011 it was a part of the Icelandic Defence Agency (Varnarmálastofnun Íslands), but is now under the Coast Guard.
