East Coast Naval Base
military unit

East Coast Naval Base (Swedish: Ostkustens marinbas, MarinB O) was a Swedish Navy command body which operated in various forms between the years 1928 and 2004. It was located in Stockholm from 1928 to 1966 and then in Haninge Municipality from 1966 to 2004.
History
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 (initially only in the war organization, but later in war as well as in peace). The East Coast Naval District (Ostkustens marindistrikt, MDO), based in Stockholm, stretched from Öregrundsgrepen, near Gräsö (Björn's Lighthouse) to the northern part of Kalmar Strait (Kråkelund). The naval districts replaced the naval stations and were upgraded in 1957 to naval commands (marinkommandon) and was given operational responsibility (higher regional level). From 1966 to 1990 they were called naval bases (örlogsbaser) and patrol areas (bevakningsområden). 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 (lower regional level). 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.

Why this record matters
The phrase “military unit” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Feb 2, 2026. The linked authority identifier is Q10613164. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1928, 2004, 1966 and 1925.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
