 This resulted in the creation of the first two regiments, Vaxholm Coastal Artillery Regiment (KA 1) and Karlskrona Coastal Artillery Regiment (KA 2).Detachments from these two regiments were also responsible for keeping units at Fårösund Fortress on the northern tip of Gotland and at Älvsborg coastal fortresses, located near the main shipping channel into Gothenburg.During the First World War, it was also decided that the area of responsibility should also include the stationing of units at Hemsö and at Luleå (until 1953 a detachment from Älvsborg which, finally, in 1975, was made into a separate regiment, the Härnösand Coastal Artillery Regiment).
