Tordenskjold-class coastal defence ship

Template:Infobox ship imageTemplate:Infobox ship class overviewTemplate:Infobox ship characteristics

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 (Template:HNoMS and Template:HNoMS) remained the backbone (alongside the slightly newer Template:Sclass) of the Royal Norwegian Navy until they were considered 'unfit for war' in the mid-1930s.

Description

Designed and built as typical pre-dreadnought battleships, although on a scale more suited to the fjords and narrow waters of Norway, the Tordenskjold class carried guns in a wide range of calibers:

• Two 21 cm/45 (8.2 inch) guns in turrets fore and aft as the main armament.
• Six 12 cm/45 (4.7 inch), mounted three on each side in a central battery, as the secondary armament.
• Six 7.6 cm/40 (3 inch) guns, also mounted in the central battery, as the tertiary armament.
• Six 1-pdr Quick Fire guns. These were meant to be used against torpedo boats.

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:

• 7 inch (17.78 cm) Harvey armour in the belt
• 8 inch (20.32 cm) of the same armour on the turrets

Fate

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.
