context_page_description: HMS Resolution was one of five Revenge-class battleships built for the Royal Navy during the First World War. Completed in December 1916, Resolution saw no combat during the war as both the British and German fleets adopted a more cautious strategy after the Battle of Jutland in May owing to the increasing threat of naval mines and submarines.
  Resolution spent the 1920s and 1930s alternating between the Atlantic Fleet and the Mediterranean Fleet. Whilst serving in the Mediterranean in the early 1920s, the ship went to Turkey twice in response to crises arising from the Greco-Turkish War, including the Great Fire of Smyrna in 1922. She also saw limited involvement during the Franco-British intervention in the Russian Civil War in the Black Sea in 1920. The ship's interwar career was otherwise uneventful. With the outbreak of the Second World War in September 1939, Resolution was assigned to the Channel Force before being transferred to convoy escort duties in the North Atlantic. In May 1940, she participated in the Battles of Narvik until German air attacks drove her off.
context_section_description: The Revenge-class super-dreadnought battleships were designed as slightly smaller, slower, and more heavily protected versions of the preceding Queen Elizabeth-class battleships. As an economy measure they were intended to revert to the previous practice of using both fuel oil and coal, but First Sea Lord Jackie Fisher rescinded the decision for coal in October 1914. Still under construction, the ships were redesigned to employ oil-fired boilers that increased the power of the engines by 9,000 shaft horsepower (6,700 kW) over the original specification.
  Resolution had a length overall of 620 feet 7 inches (189.2 m), a beam of 88 feet 6 inches (27.0 m) and a deep draught of 33 feet 7 inches (10.2 m). She had a designed displacement of 25,750 long tons (26,160 t) and displaced 31,130 long tons (31,630 t) at deep load. She was powered by two pairs of Parsons steam turbines, each driving two shafts, using steam from eighteen Yarrow boilers. The turbines were rated at 40,000 shp (30,000 kW) and intended to give the ship a maximum speed of 23 knots (42.6 km/h; 26.5 mph). During her sea trials on 22 May 1916, the ship only reached a top speed of 22 knots (41 km/h; 25 mph) from 40,360 shp (30,100 kW). She had a range of 7,000 nautical miles (12,964 km; 8,055 mi) at a cruising speed of 10 knots (18.5 km/h; 11.5 mph). Her crew numbered 910 officers and enlisted men in 1916. Her metacentric height was 3.4 feet (1.0 m) at deep load.
  The Revenge class was equipped with eight breech-loading (BL) 15-inch (381 mm) Mk I guns in four twin gun turrets, in two superfiring pairs fore and aft of the superstructure, designated 'A', 'B', 'X', and 'Y' from front to rear. Twelve of the fourteen BL 6-inch (152 mm) Mk XII guns were mounted singly in casemates along the broadside of the vessel amidships; the remaining pair were mounted on the shelter deck and were protected by gun shields. The ship also mounted four 3-pounder (47-millimetre (1.9 in)) guns. Her anti-aircraft (AA) armament consisted of two quick-firing (QF) 3-inch (76 mm) 20 cwt Mk I guns. She was fitted with four submerged 21 inch (533 mm) torpedo tubes, two on each broadside.
  Resolution was completed with two fire-control directors fitted with 15-foot (4.6 m) rangefinders. One was mounted above the conning tower, protected by an armoured hood, and the other was in the spotting top above the tripod foremast. Each turret was also fitted with a 15-foot rangefinder. The main armament could be controlled by 'X' turret as well. The secondary armament was primarily controlled by directors mounted on each side of the compass platform on the foremast once they were fitted in April 1917. A torpedo-control director with a 15-foot rangefinder was mounted at the aft end of the superstructure.
  The ship's waterline belt consisted of Krupp cemented armour (KC) that was 13 inches (330 mm) thick between 'A' and 'Y' barbettes and thinned to 4 to 6 inches (102 to 152 mm) towards the ship's ends, but did not reach either the bow or the stern. Above this was a strake of armour 6 inches thick that extended between 'A' and 'X' barbettes. Transverse bulkheads 4 to 6 inches thick ran at an angle from the ends of the thickest part of the waterline belt to 'A' and 'Y' barbettes. The gun turrets were protected by 11 to 13 inches (279 to 330 mm) of KC armour, except for the turret roofs which were 4.75–5 inches (121–127 mm) thick. The barbettes ranged in thickness from 6–10 inches (152–254 mm) above the upper deck, but were only 4 to 6 inches thick below it. The Revenge-class ships had multiple armoured decks that ranged from 1 to 4 inches (25 to 102 mm) in thickness. The main conning tower had 13 inches of armour on the sides with a 3-inch roof. The torpedo director in the rear superstructure had 6 inches of armour protecting it. After the Battle of Jutland, 1 inch of high-tensile steel was added to the main deck over the magazines and additional anti-flash equipment was added in the magazines.
  The ship was fitted with flying-off platforms mounted on the roofs of 'B' and 'X' turrets in 1918, from which fighters
