HSwMS Gustaf V, in Swedish HM Pansarskepp Gustaf V (His Majesty's Armoured Ship Gustaf V) was a of the Swedish Navy. The vessel was the third and last ship in the Sverige class along with and . Gustaf V was launched on 15 September 1917 at Kockums in Malmö and delivered to the Navy on 9 January 1922. The design consisted of four 28 cm cannon and a secondary armament of eight 15.2 cm cannon. During the interwar period, the ship underwent several modernizations and was one of the most powerful vessels in the fleet during the Second World War. The ship was put in reserve in 1948, was decommissioned in 1957 and was later sold for scrapping in Karlskrona. However, the ship remained at Berga Academy of War as of 1968. Two of the ship's 15.2 cm guns are preserved in the battery at Häggmansberget in the defensive Kalix Line, around Kalix. Design Gustaf V was long, wide and had a depth of . The hull was made of nitrated steel with overlapping plates with an armored belt at the waterline and on the citadel. The bow was designed with a forward sloping Atlantic bow which gave her the ability to act as an icebreaker. Unlike her sister ship HSwMS Sverige, Gustaf V was not designed as a flagship but instead received two bunks for 22 cadets and engineers. Machinery The machinery consisted of twelve coal-fired boilers that delivered steam to two steam turbines. The boilers were placed in two groups of six, which necessitated two funnels. The boilers delivered steam to two independent turbine assemblies with a high-pressure turbocharger and a low-pressure turbine. The turbine movement was transmitted to each propeller shaft via a 17.23: 1 gear ratio which allowed turbines to operate at a rotational speed of about 3,459 RPM and propellers at 200 RPM. This method gave the machinery better efficiency than HSwMS Sverige, which did not have a reduction gear. This resulted in an increased power output by 20 percent. In addition, coal consumption decreased, which increased the ships range. Gustaf Vs machinery developed 22,000 horsepower, which gave the vessel a speed of 23.2 knots. Armament The main artillery on Gustaf V consisted of four 28 cm M/12 cannons that were placed in two double turrets, one on the bow and one on the stern. The projectiles weighed with a range of .
