HSwMS Uppland was a Öland-class destroyer which served with the Royal Swedish Navy. Larger and more stable than previous Swedish destroyers, the vessel was launched on 15 December 1948. Armament was based around two twin mounting for semi-automatic 120 mm (4.7 in) guns, an extensive anti-aircraft defence of seven 40 mm (1.6 in) and eight 25 mm (1 in) guns and a quadruple 375 mm (15 in) anti-submarine rocket launcher, as well as torpedoes and mines. The ship was upgraded in 1963, which involved the addition of a helicopter platform amongst other alterations, and reclassified as a frigate in 1974, until ultimately being retired on 1 July 1978 as part of a strategy to remove larger combat vessels from the fleet.
