The Öland design carried four 120 mm Bofors guns in twin dual-purpose mounts, supported by seven 40 mm and eight 25 mm anti-aircraft guns. Six 533 mm torpedo tubes in two triple mountings provided a heavy surface strike. Four depth-charge throwers, two racks, and capacity for 60 mines supported anti-submarine work and coastal defence; a Squid anti-submarine mortar was added after refit. Orders in 1943 and launches in 1945 led to postwar completion, with Öland entering service in 1947. Double-hull and welded construction accompanied the increase in size and weapons. A destroyer of this scale could have fitted the cruiser category of about twenty years earlier.
