Early Swedish kings ( 9th–14th centuries) organised a Swedish Navy along the coastline through . This involved combined rowing and sailing ships (without artillery). This system became obsolete with the development of society and changes in military technology. No later than in the 14th century, the duty to serve in was replaced by a tax. In 1427, when Sweden was part of the
Kalmar Union (with Denmark and Norway), Swedish warships did however participate in the naval battle of Öresund against the
Hanseatic League. It is unclear how this force was organised and exactly on what basis. On 7 June 1522, one year after the separation of Sweden from the Kalmar Union,
Gustav Vasa purchased a number of ships from the
Hanseatic town of
Lübeck. Official Swedish histories since the 19th century have often recorded this day as the birth of the current Swedish Navy. The museum ship in Stockholm was a 17th-century ship of the Royal Swedish Navy (). by
Adolf Ulrik Schützercrantz The Amphibious Corps dates back to 1 January 1902, when a separate "
Coastal Artillery" () was established, and came into use as the name of the service as a whole. The last decade of the 20th century saw the abandonment of the coastal fortifications and the force became a more regular marine corps, renamed Amphibious Corps () in 2000. For most of the twentieth century, the Swedish Navy focused on the threat of a full-scale invasion of Sweden via the
Baltic Sea and on protecting commercial shipping. Sweden's location on the Scandinavian peninsula makes it highly dependent of maritime trade: 90% imports and exports enter or leave Sweden through the Baltic. In 1972, the government decreed that non-military measures should be used to protect merchant shipping. The resolution led to the decommissioning of all the navy's destroyers and frigates, though the non-military measures the government intended to use to protect shipping have never been specified. The navy first participated in a UN-mandate international operation in Kosovo through KFOR, KS04 in 2001 by the amphibious corps. The fleet participated in its first UN operation
UN-led peacekeeping mission in October 2006 when the corvette began performing coastal surveillance duties for the
United Nations Mission in Lebanon. HSwMS

EUNAVFOR operation (2008– ) off the coast of the
Horn of Africa. In 2010, was the EUNAVFOR flagship, housing the fleet headquarters led by
RAdm (LH) Jan Thörnqvist.
