The Tordenskjold class of coastal defence ships was ordered by Norway as part as the general rearmament in the time leading up to the events in 1905 - when Norway broke out of the union with Sweden - the two ships in the class (Tordenskjold and Harald Haarfagre) remained the backbone (alongside the slightly newer Eidsvold class) of the Royal Norwegian Navy until they were considered 'unfit for war' in the mid-1930s.

The Tordenskjold class was armoured to withstand battle with ships of a similar class, but her protection system could not withstand attacks from heavier ships nor underwater attacks very well:
Both ships were phased out from active duty in the mid-1930s, and were used as training vessels. After the German invasion of Norway in 1940, they were taken by the Germans and turned into floating Flak batteries. After the war they were returned to the Royal Norwegian Navy and served as barracks for a short time before they were sold for scrapping.
