Viking-class submarine

The Viking-class submarine was a planned class of submarines to be built by the Viking Submarine Corporation. Viking was a corporation jointly established by Kockums in Sweden, Kongsberg Defence & Aerospace in Norway and Odense Steel Shipyard in Denmark. Finland was an observer of the Viking project, as an eventual future buyer of additional Viking submarines. The idea was to develop modern successor to the Swedish Gotland class, that would have cost about one third of the German Type 214. It was initially planned that the Swedish, Danish, and Norwegian navies would purchase two, four, and four Viking-class submarines each starting in 2005.
