The Norwegian Coast Guard, or Kystvakten in Norwegian, is a part of the Royal Norwegian Navy, but has separate vessels, many  of which are purpose-built. All Coast Guard vessels have the prefix KV. Four of these vessels are  capable of embarking one or more helicopters. Norway's exclusive economic zone (EEZ), the Coast Guard's area of responsibility, is about 2.2 million  square kilometers, the largest in Western Europe.
The flag of the Coast Guard is the International Inspection Pennant as ratified by the North Sea Fisheries Convention of 1882. The Coast Guard was established 1 April 1977. Before that, the  functions of a coast guard had been carried out by different  organisations within the Royal Norwegian Navy. One of the oldest of  these organisations were groups of navy ships organised to prevent  foreign ships from fishing in Norwegian territorial waters. A Coast  Guard division named  Det Regionale Sjømilitære Fiskerioppsyn has  now taken on that responsibility. Even earlier, no specialized guard  system existed - guarding the home territorial waters was carried out by  regular ships from the Navy itself, and it was not until after WWI that  purpose-built vessels was constructed and commissioned.
After the Second World War, no dedicated guard and surveilaice ships  were built until 1957, when three whaling boats bought from  South-Georgia came into service as the Andenes-class; Andenes, Nordkapp  and Senja. These ship names were later handed over to those of the  Nordkapp-class in 1980. The new Nordkapp-class is still in commission  today.
The Coast Guard Squadron South is made up from the following vessels:
Leikvin, Alesund, Nornen and Njord.
KV Leikvin is seen here in Leith following a patrol in the North Sea.
