Sverige-class coastal defence ship image

The Sverige-class coastal defence ships were a class of coastal defence ships that, at the time of introduction, were the largest ships to serve in the Swedish Navy. Their design was completely new and was influenced by the ships of the time. Their armament consisted of four 283:mm (11:in)/45 cal. Bofors guns in two turrets and eight 152:mm (6:in) Bofors guns in one double and six single turrets. During the Second World War they were the backbone of the Swedish Navy.
