In accordance with the Defence Act of 1925, from 1928, six regional command and maintenance bodies for the Swedish Navy were organized within the respective coastal areas. During the 1930s, the regional naval structure was built in the form of naval districts. The East Coast Naval District, based in Stockholm, stretched from Öregrundsgrepen, near Gräsö to the northern part of Kalmar Strait. The naval districts replaced the naval stations and were upgraded in 1957 to naval commands and was given operational responsibility. From 1966 to 1990 they were called naval bases and patrol areas. In 1966, new and from then on integrated military districts were established, which took over some of the tasks of the naval commands. Other tasks were transferred simultaneously to the newly established naval bases. During the period 1981-1990, the naval bases were amalgamated with respective coastal artillery defence and formed naval commands - now at a lower regional level. For East Coast Naval Base, this meant that it was amalgamated with Stockholm Coastal Artillery Defense and formed the East Coast Naval Command. The lower regional organization had command duties and was responsible for, among other things, maritime surveillance and maritime maintenance, base services. The majority of the regional structure was discontinued in 2000 and replaced with two naval bases and a naval shipyard. At the same time the Naval Tactical Command was established. The organization was formed on 1 July 2000 and took over certain parts of the operation after the East Coast Naval Command. The Naval Base was formed on 1 January 2005 after the Defence Act of 2004. The Naval Base took over the main tasks previously relinquished to the East Coast Naval Base and the South Coast Naval Base. Today, it is the Naval Base, which has in principle taken over the remaining naval tasks of the lower regional structure.
