The Coast Guard consists of three ships and four aircraft and armed with small arms, naval artillery, and Air Defense weaponry.[5] The Coast Guard also maintains the Icelandic Air Defense System, formerly part of the disestablished Defence Agency, which conducts ground surveillance of Iceland's air space.[5][6]
Units subordinated to the National Commissioner also take part in Iceland's defences. Foremost of these are the National Security Unit, which handles intelligence operations and the special unit Víkingasveitin, a highly trained and equipped counter terrorism unit which is part of the National Police force.
