context: The entire rationalization of the Defense Forces also affected the Hanko Coastal Battery and was reintroduced to its original roots by the Navy in the Gulf of Finland Marine Defense Area on July 1, 1998. Due to cost savings, several buildings were abandoned and staff were reduced. Military classes decreased and the need for training places decreased. Several wars around the world showed limited access to solid coastal artillery, and the need for heavy fortresses ran out. The Hanko Coastal Battery was discontinued on December 31, 2002. [1] Some of the Coast Guard's tasks with modern and usable fleet equipment will continue to be carried out by the Finnish Navy's Coastal Regiment of Suomenlinna and will also be regularly practicing in the former Hanko Coastal Battery area [12].
