The Icelandic Coast Guard (, or simply ) is the Icelandic defence service responsible for search and rescue, maritime safety and security surveillance, and law enforcement. The Coast Guard maintains the Iceland Air Defence System which conducts ground-based surveillance of Iceland's air space and operate Keflavik airbase. It is also responsible for hydrographic surveying and nautical charting. History Its origins can be traced to 1859, when the corvette Ørnen started patrolling Icelandic waters. In 1906, Iceland's first purposely built guard-ship, Islands Falk, began operation. Iceland's own defense of its territorial waters began around 1920 and the Icelandic Coast Guard was formally founded on 1 July 1926. The first cannon was put on the trawler Þór in 1924 and on 23 June 1926 the first ship built for the Coast Guard, named Óðinn, arrived in Iceland. Three years later, on 14 July 1929 the coastal defence ship Ægir was added to the Coast Guard fleet. Cod Wars The Icelandic Coast Guard played its largest role during the fishing rights dispute known as the Cod Wars, between 1972 and 1976, when the Coast Guard ships would cut the trawl wires of British and West German trawlers, resulting in confrontations with Royal Navy warships and tugs from the British Ministry of Agriculture, Fisheries and Food (MAFF). The Icelandic Coast Guard goal was to enforce a disputed expansion of Iceland's exclusive economic zone. Engagements between Icelandic gunboats and British warships involving ramming became the tactic of choice during this conflict. At least 15 British frigates, five Icelandic patrol boats and one British supply ship were damaged by ramming between 1975 and 1976. In the end, Iceland achieved its overall ambition of expanding its exclusive fishery zone to by June 1976. Operations The Icelandic Coast Guard's (ICG) primary mission as stipulated in Section 1 of Act on Icelandic Coast Guard is conduct search and rescue, maritime safety and security surveillance, and law enforcement inside the -wide economic zone. The Coast Guard operates Joint Rescue and Coordination Centre (JRCC) Iceland which is responsible for search and rescue of vessels and aircraft in Iceland's search and rescue region (SRR) according to International Aeronautical and Maritime Search and Rescue (IAMSAR) Manual. Additionally the ICG is in the charge of defusing naval mines, most of which were laid during the Second World War, and monitoring fisheries in international waters outside of the Icelandic economic zone in order to blacklist
