HSwMS Mjölner was a coastal destroyer of the Royal Swedish Navy, built by Eriksbergs Mekaniska Verkstad and launched on 9 April 1942 as the last of the four ship Mode class. Originally given the pennant number 32, the ship was reclassified a frigate in 1953 with the pennant number 76.
Design
Mjölner was based on the design the Spica class.[1] The vessel was small and designed for coastal operation, displacing 750 tonnes (740 long tons; 830 short tons) standard and 960 tonnes (940 long tons; 1,060 short tons) full load.[2] The machinery consisted of two Penhoët A oil-fired boilers, which supplied steam to two de Laval steam turbines, each driving its own propeller, providing a top speed of 30 knots (35 mph; 56 km/h).
Armament
The main armament consisted of three 10.5 cm (4.1 in) guns produced by Bofors.[3] These were placed in separate mounts, one on the fore deck, one on the aft deck and one on the aft superstructure. Air defence consisted of two 40 mm (1.6 in) and two 20 mm (0.79 in) anti-aircraft guns, also provided by Bofors. Three torpedo tubes for 53 cm (21 in) torpedoes were triple mounted aft of the superstructure and two depth charge throwers were mounted further towards the stern. 42 mines could also be carried for minelaying.
Service
Mjölner was launched on 9 April 1942 and commissioned on 12 November later that year, serving with the Coastal Fleet through World War II.[4]
In 1946, Mjölner accompanied Fylgia and Munin on a tour of Bergen and Fannefjord in Norway, Dublin in Ireland and Antwerp in Belgium.[5]
Modernisation
Mjölner was modernised in 1953 and re-rated as a frigate.[3] One of the 105 mm (4.1 in) main guns was removed, along with the triple 533 mm (21 in) torpedo tube. A single Squid depth charge launcher was fitted to improve anti-submarine capabilities and the 40 mm (1.6 in) guns were upgraded.
Disposal
Mjölner was decommissioned on 1 April 1966 and was sold for scrap on 3 November 1969.[2]
