Öland

When choosing the best design for a new destroyer, Swedish experts studied foreign ships. They noted a trend toward an increase in displacement and main caliber weaponry being "dual purpose" with increasing frequency. In 1941 and 1942, a series of ship projects with 1,750 to 2,500 tons displacements, speeds of 35–38 knots, and main battery armament of 2–3 twin-gun mounts were presented. Öland and Uppland were built according to a compromise project incorporating two of the latest main battery mounts designed for maximum rate of fire. The project turned out to be a success, although a belated one. Over her years of service, the destroyer underwent four upgrades, including the installation of radars and the latest anti-submarine equipment.
