HMS Courageous was the lead ship of her class of three battlecruisers built for the Royal Navy in the First World War. Designed to support the Baltic Project championed by First Sea Lord John Fisher, the ship was very lightly armoured and armed with only a few heavy guns. Courageous was completed in late 1916 and spent the war patrolling the North Sea. She participated in the Second Battle of Heligoland Bight in November 1917 and was present when the German High Seas Fleet surrendered a year later.

Courageous was decommissioned after the war, then rebuilt as an aircraft carrier in the mid-1920s. She could carry 48 aircraft, compared with 36 carried by her half-sister Furious on about the same displacement. After recommissioning she spent most of her career operating off Great Britain and Ireland. She briefly became a training ship, but reverted to her normal role a few months before the start of the Second World War in September 1939. A German U-boat sank Courageous by torpedo later that month, with the loss of more than 500 of her crew.

Origin and construction

In the First World War, Admiral Fisher was prevented from ordering an improved version of the preceding Renown-class battlecruisers by a wartime restriction that banned construction of ships larger than light cruisers in 1915. To obtain ships suitable for the doctrinal roles of battlecruisers, such as scouting for fleets and hunting enemy raiders, he settled on ships with the minimal armour of a light cruiser and the armament of a battlecruiser. He justified their existence by claiming he needed fast, shallow-draught ships for his Baltic Project, a plan to invade Germany via its Baltic coast. [1] [2]

Courageous had an overall length of 786 feet 9 inches (239.8 m), a beam of 81 feet (24.7 m), and a draught of 25 feet 10 inches (7.9 m) at deep load. She displaced 19,180 long tons (19,490 t) at load and 22,560 long tons (22,922 t) at deep load. [3] Courageous and her sisters were the first large warships in the Royal Navy to have geared steam turbines. To save design time, the installation used in the light cruiser Champion, the first cruiser in the navy with geared turbines, was simply replicated for four turbine sets. The Parsons turbines were powered by eighteen Yarrow small-tube boilers. They were designed to produce a total of 90,000 shaft horsepower (67 MW) at a working pressure of 235  psi (1,620  kPa ; 17  kgf/cm2 ). The ship reached an estimated 30.8 knots (57.0 km/h; 35.4 mph) on sea trials. [4]

The ship's normal design load was 750 long tons (762 t) of fuel oil, but she could carry a maximum of 3,160 long tons (3,211 t). At full capacity, she could steam for an estimated 6,000 nautical miles (11,110 km; 6,900 mi) at a speed of 20 knots (37 km/h; 23 mph). [5]

Courageous carried four BL 15-inch Mk I guns in two hydraulically powered twin gun turrets, designated 'A' and 'Y' from front to rear. Her secondary armament consisted of eighteen BL 4-inch Mk IX guns mounted in six manually powered mounts. [5] The mount placed three breeches too close together, causing the 23 loaders to get in one another's way, and preventing the intended high rate of fire. [6] A pair of QF 3-inch 20 cwt [Note 1] anti-aircraft guns were fitted abreast the mainmast on Courageous. She mounted two submerged tubes for 21-inch torpedoes and carried 10 torpedoes for them. [5]

First World War

Courageous was laid down on 26 March 1915, launched on 5 February 1916 and completed on 4 November. On her sea trials later that month, she sustained structural damage while running at full speed in a rough head sea; the exact cause is uncertain. [7] The forecastle deck was deeply buckled in three places between the breakwater and the forward turret. [8] The side plating was visibly buckled between the forecastle and upper decks. Water had entered the submerged torpedo room and rivets had sheared in the angle irons securing the deck armour in place. [9] The ship was stiffened with 130 long tons (130 t) of steel in response. [7] As of 23 November 1916, she cost £2,038,225 to build. [10]

Upon commissioning, Courageous was assigned to the 3rd Light Cruiser Squadron of the Grand Fleet. She became flagship of the 1st Cruiser Squadron near the end of 1916 when that unit was re-formed after most of its ships had been sunk at the Battle of Jutland in May. [11] The ship was temporarily fitted as a minelayer in April 1917 by the addition of mine rails on her quarterdeck that could hold over 200 mines, but never laid any mines. In mid-1917, she received half a dozen torpedo mounts, each with two tubes: one mount on each side of the mainmast on the upper deck and two mounts on each side of the rear turret on the quarterdeck. [12] [13] On 30 July 1917, Rear-Admiral Trevylyan Napier assumed command of the 1st Cruiser Squadron and was appointed Acting Vice-Admiral Commanding the Light Cruiser Force until he was relieved on 26 October 1918. [14]

On 16 October 1917, the Admiralty received word of German ship movements, possibly indicating a raid. Admiral Beatty, the commander of the Grand Fleet, ordered most of his light cruisers and destroyers to sea in an effort to locate the enemy ships. Courageous and Glorious were not initially included amongst them, but were sent to reinforce the 2nd Light Cruiser Squadron patrolling the central part of the North Sea later that day. [15] Two German Brummer-class light cruisers managed to slip through the gaps between the British patrols and destroy a convoy bound for Norway on the morning of 17 October, but no word was received of the engagement until that afternoon. The 1st Cruiser Squadron was ordered to intercept, but was unsuccessful as the German cruisers were faster than expected. [16]

Second Battle of Heligoland Bight

Throughout 1917 the Admiralty was becoming more concerned about German efforts to sweep paths through the British-laid minefields intended to restrict the actions of the High Seas Fleet and German submarines. A preliminary raid on German minesweeping forces on 31 October by light forces destroyed ten small ships. Based on intelligence reports, the Admiralty allocated the 1st Cruiser Squadron on 17 November 1917, with cover provided by the reinforced 1st Battlecruiser Squadron and distant cover by the battleships of the 1st Battle Squadron, to destroy the minesweepers and their light cruiser escorts. [17]

The German ships—four light cruisers of II Scouting Force, eight destroyers, three divisions of minesweepers, eight Sperrbrecher s (cork-filled trawlers) and two other trawlers to mark the swept route—were spotted at 7:30 am. [Note 2] Courageous and the light cruiser Cardiff opened fire with their forward guns seven minutes later. The Germans responded by laying an effective smoke screen. The British continued in pursuit, but lost track of most of the smaller ships in the smoke and concentrated fire on the light cruisers. Courageous fired 92 fifteen-inch shells and 180 four-inch shells in the battle, [18] and the only damage she received was from her own muzzle blast. [19] One fifteen-inch shell hit a gun shield of the light cruiser SMS Pillau but did not affect her speed. At 9:30 the 1st Cruiser Squadron broke off their pursuit so that they would not enter a minefield marked on their maps; the ships turned south, playing no further role in the battle. [20]

After the battle, the mine fittings on Courageous were removed, and she spent the rest of the war intermittently patrolling the North Sea. In 1918, short take-off platforms were fitted for a Sopwith Camel and a Sopwith 1½ Strutter on both 15-inch (380 mm) turrets. [21] The ship was present at the surrender of the German High Seas fleet on 21 November 1918. [13] Courageous was placed in reserve at Rosyth on 1 February 1919 and she again became Napier's flagship as he was appointed Vice-Admiral Commanding the Rosyth Reserve until 1 May, [14] The ship was assigned to the Gunnery School at Portsmouth the following year as a turret drill ship. She became flagship of the Rear-Admiral Commanding the Reserve at Portsmouth in March 1920. [22] Captain Sidney Meyrick became her Flag Captain in 1920. [23] He was relieved by Capt John Casement in August 1921. [24]

Between the wars

Conversion

The Washington Naval Treaty of 1922 severely limited capital ship tonnage, and the Royal Navy was forced to scrap many of its older battleships and battlecruisers. The treaty allowed the conversion of existing ships totalling up to 66,000 long tons (67,059 t) into aircraft carriers, and the Courageous class's combination of a large hull and high speed made these ships ideal candidates. The conversion of Courageous began on 29 June 1924 at Devonport. [25] Her fifteen-inch turrets were placed into storage and reused in the Second World War for HMS Vanguard, the Royal Navy's last battleship. [26] The conversion into an aircraft carrier cost £2,025,800. [27]

The ship's new design improved on her half-sister HMS Furious, which lacked an island and a conventional funnel. All superstructure, guns, torpedo tubes, and fittings down to the main deck were removed. A two-storey hangar was built on top of the remaining hull; each level was 16 feet (4.9 m) high and 550 feet (167.6 m) long. The upper hangar level opened onto a short flying-off deck, below and forward of the main flight deck. The flying-off deck improved launch and recovery cycle flexibility until new fighters requiring longer takeoff rolls made the lower deck obsolete in the 1930s. [28] Two 46-by-48-foot (14.0 m × 14.6 m) lifts were installed fore and aft in the flight deck. An island with the bridge, flying control station and funnel was added on the starboard side, since islands had been found not to contribute significantly to turbulence. By 1939 the ship could carry 34,500 imperial gallons (157,000 L; 41,400 US gal) of petrol for her aircraft. [29]

Courageous received a dual-purpose armament of sixteen QF 4.7-inch Mk VIII guns in single HA Mark XII mounts. Each side of the lower flight deck had a mount, and two were on the quarterdeck. The remaining twelve mounts were distributed along the sides of the ship. [30] In refits in the mid-1930s, Courageous received three quadruple Mk VII mounts for 40-millimetre (1.6 in) 2-pounder "pom-pom" anti-aircraft guns, two of which were transferred from the battleship Royal Sovereign. Each side of the flying-off deck had a mount, forward of the 4.7-inch guns, and one was behind the island on the flight deck. She also received four water-cooled .50-calibre Mk III anti-aircraft machine guns in a single quadruple mounting. This was placed in a sponson on the port side aft. [31]

The reconstruction was completed on 21 February 1928, and the ship spent the next several months on trials and training before she was assigned to the Mediterranean Fleet to be based at Malta, in which she served from May 1928 to June 1930. [32] In August 1929, the 1929 Palestine riots broke out, and Courageous was ordered to respond. When she arrived off Palestine, her air wing was disembarked to carry out operations to help to suppress the disorder. [33] The ship was relieved from the Mediterranean by Glorious and refitted from June to August 1930. She was assigned to the Atlantic and Home Fleets from 12 August 1930 to December 1938, aside from a temporary attachment to the Mediterranean Fleet in 1936. In the early 1930s, traverse arresting gear was installed and she received two hydraulic aircraft catapults on the upper flight deck before March 1934. Courageous was refitted again between October 1935 and June 1936 with her pom-pom mounts. She was present at the Coronation Fleet Review at Spithead on 20 May 1937 for King George VI. The ship became a training carrier in December 1938 when Ark Royal joined the Home Fleet. She was relieved of that duty by her half-sister Furious in May 1939. Courageous participated in the Portland Fleet Review on 9 August 1939. [32]

Courageous could carry up to 48 aircraft; following completion of her trials and embarking stores and personnel, she sailed for Spithead on 14 May 1928. The following day, a Blackburn Dart of 463 Flight made the ship's first deck landing. The Dart was followed by the Fairey Flycatchers of 404 and 407 Flights, the Fairey IIIFs of 445 and 446 Flights and the Darts of 463 and 464 Flight. The ship sailed for Malta on 2 June to join the Mediterranean Fleet. [34]

From 1933 to the end of 1938 Courageous carried No. 800 Squadron, which flew a mixture of nine Hawker Nimrod and three Hawker Osprey fighters. [35] 810, 820 and 821 Squadrons were embarked for reconnaissance and anti-ship attack missions in the same period. They flew the Blackburn Baffin, the Blackburn Shark, the Blackburn Ripon and the Fairey Swordfish torpedo bombers as well as Fairey Seal reconnaissance aircraft. [36] As a deck landing training carrier, in early 1939 Courageous embarked the Blackburn Skua and Gloster Sea Gladiator fighters of 801 Squadron and the Swordfish torpedo bombers of 811 Squadron, although both of these squadrons were disembarked when the ship was relieved of her training duties in May. [37]

Second World War and sinking

Courageous served with the Home Fleet at the start of World War II with 811 and 822 Squadrons aboard, each squadron equipped with a dozen Fairey Swordfish. [38] In the early days of the war, hunter-killer groups were formed around the fleet's aircraft carriers to find and destroy U-boats. On 31 August 1939 she went to her war station at Portland and embarked the two squadrons of Swordfish. Courageous departed Plymouth on the evening of 3 September 1939 for an anti-submarine patrol in the Western Approaches, escorted by four destroyers. [34] On the evening of 17 September 1939, she was on one such patrol off the coast of Ireland. Two of her four escorting destroyers had been sent to help a merchant ship under attack and all her aircraft had returned from patrols. U-29, commanded by Captain-Lieutenant Otto Schuhart, stalked Courageous for more than two hours. The carrier then turned into the wind to launch her aircraft. This put the ship right across the bow of the submarine, which fired three torpedoes. Two of the torpedoes struck the ship on her port side before any aircraft took off, knocking out all electrical power, and she capsized and sank in 20 minutes with the loss of 519 of her crew, including her captain. [39] The US cargo ship Collinsgworth, Ellerman Lines cargo ship Dido, and Dutch ocean liner Veendam rescued survivors. The two escorting destroyers counterattacked U-29 for four hours, but the submarine escaped. [40]

An earlier unsuccessful attack on Ark Royal by U-39 on 14 September, followed by the sinking of Courageous three days later, prompted the Royal Navy to withdraw its carriers from anti-submarine patrols. Courageous was the first British warship to be sunk by German forces. (The submarine Oxley had been sunk a week earlier by friendly fire from the British submarine Triton.) [41] The commander of the German submarine force, Commodore Karl Dönitz, regarded the sinking of Courageous as "a wonderful success" and it led to widespread jubilation in the Kriegsmarine (German navy). Grand Admiral Erich Raeder, commander of the Kriegsmarine, directed that Schuhart be awarded the Iron Cross First Class and that all other members of the crew receive the Iron Cross Second Class.

<span class="mw-page-title-main">Battlecruiser</span> Large capital warship, typically faster than battleships

The battlecruiser was a type of capital ship of the first half of the 20th century. These were similar in displacement, armament and cost to battleships, but differed in form and balance of attributes. Battlecruisers typically had thinner armour and a somewhat lighter main gun battery than contemporary battleships, installed on a longer hull with much higher engine power in order to attain greater speeds. The first battlecruisers were designed in the United Kingdom, as a development of the armoured cruiser, at the same time as the dreadnought succeeded the pre-dreadnought battleship. The goal of the design was to outrun any ship with similar armament, and chase down any ship with lesser armament; they were intended to hunt down slower, older armoured cruisers and destroy them with heavy gunfire while avoiding combat with the more powerful but slower battleships. However, as more and more battlecruisers were built, they were increasingly used alongside the better-protected battleships.

HMS <i>Hermes</i> (95) 1924 unique aircraft carrier

HMS Hermes was a British aircraft carrier built for the Royal Navy and was the world's first ship to be designed as an aircraft carrier, although the Imperial Japanese Navy's Hōshō was the first to be commissioned. The ship's construction began during the First World War, but she was not completed until after the end of the war, having been delayed by multiple changes in her design after she was laid down. After she was launched, the Armstrong Whitworth shipyard which built her closed, and her fitting out was suspended. Most of the changes made were to optimise her design, in light of the results of experiments with operational carriers.

HMS <i>Formidable</i> (67) 1940 Illustrious-class aircraft carrier of the Royal Navy

HMS Formidable was an Illustrious-class aircraft carrier ordered for the Royal Navy before the Second World War. After being completed in late 1940, she was briefly assigned to the Home Fleet before being transferred to the Mediterranean Fleet as a replacement for her crippled sister ship Illustrious. Formidable's aircraft played a key role in the Battle of Cape Matapan in early 1941, and they subsequently provided cover for Allied ships and attacked Axis forces until their carrier was badly damaged by German dive bombers in May.

<i>Courageous</i>-class aircraft carrier Multi-ship class of aircraft carrier

The Courageous class, sometimes called the Glorious class, was the first multi-ship class of aircraft carriers to serve with the Royal Navy. The three ships—Furious, Courageous and Glorious—were originally laid down as Courageous-class battlecruisers as part of the Baltic Project during the First World War. While very fast, their minimal armour and few guns limited their long-term utility in the post-war Royal Navy, and they were laid up after the war. They were considered capital ships by the terms of the 1922 Washington Naval Treaty and were included in the total amount of tonnage allowed to the Royal Navy. Rather than scrap them, the Navy decided to convert them to aircraft carriers as permitted under the Treaty.

HMS <i>Glorious</i> Royal Navy aircraft carrier sunk in WWII

HMS Glorious was the second of the three Courageous-class battlecruisers built for the Royal Navy during the First World War. Designed to support the Baltic Project championed by the First Sea Lord, Lord Fisher, they were relatively lightly armed and armoured. Glorious was completed in late 1916 and spent the war patrolling the North Sea. She participated in the Second Battle of Heligoland Bight in November 1917 and was present when the German High Seas Fleet surrendered a year later.

HMS <i>Revenge</i> (06) 1916 Lead Revenge-class battleship of the Royal Navy

HMS Revenge was the lead ship of five Revenge-class super-dreadnought battleships built for the Royal Navy during the First World War in the mid-1910s. The ships were developments of the Queen Elizabeth-class battleships, with reductions in size and speed to offset increases in armour protection whilst retaining the same main battery of eight 15-inch (381 mm) guns. She was laid down in 1913, launched in 1915 and commissioned in February 1916, early enough to be worked up to see action with the Grand Fleet at the Battle of Jutland in May that year. During the engagement, she engaged German battlecruisers, damaging two of them before being forced to turn away to avoid torpedoes that damaged her squadron flagship and caused the squadron to lose contact with the rest of the fleet. Revenge emerged from the battle unscathed, but she saw no further action during the war, as the British and German fleets turned to more cautious strategies owing to the risk of submarines and naval mines.

HMS <i>Royal Sovereign</i> (05) 1916 Revenge-class battleship of the Royal Navy

HMS Royal Sovereign was a Revenge-class battleship of the Royal Navy displacing 29,970 long tons (30,450 t) and armed with eight 15-inch (381 mm) guns in four twin-gun turrets. She was laid down in January 1914 and launched in April 1915; she was completed in May 1916, but was not ready for service in time to participate in the Battle of Jutland at the end of the month. She served with the Grand Fleet for the remainder of the First World War, but did not see action. In the early 1930s, she was assigned to the Mediterranean Fleet and based in Malta.

HMS <i>Resolution</i> (09) 1916 Revenge-class battleship of the Royal Navy

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.

HMS <i>Valiant</i> (1914) 1914 Queen Elizabeth-class battleship of the Royal Navy

HMS Valiant was one of five Queen Elizabeth-class battleships built for the Royal Navy during the early 1910s. She participated in the Battle of Jutland during the First World War as part of the Grand Fleet. Other than that battle, and the inconclusive Action of 19 August, her service during the war generally consisted of routine patrols and training in the North Sea. She saw further action during the Second World War in the Mediterranean and Far East.

HMS <i>Barham</i> (04) Queen Elizabeth-class battleship

HMS Barham was one of five Queen Elizabeth-class battleships built for the Royal Navy during the early 1910s. Completed in 1915, she was often used as a flagship and participated in the Battle of Jutland during the First World War as part of the Grand Fleet. For the rest of the war, except for the inconclusive action of 19 August 1916, her service generally consisted of routine patrols and training in the North Sea.

<i>Renown</i>-class battlecruiser Battlecruisers built during the First World War

The Renown class consisted of two battlecruisers built during the First World War for the Royal Navy. They were originally laid down as improved versions of the Revenge-class battleships, but their construction was suspended on the outbreak of war on the grounds they would not be ready in a timely manner. Admiral Lord Fisher, upon becoming First Sea Lord, gained approval to restart their construction as battlecruisers that could be built and enter service quickly. The Director of Naval Construction (DNC), Eustace Tennyson-D'Eyncourt, quickly produced an entirely new design to meet Admiral Lord Fisher's requirements and the builders agreed to deliver the ships in 15 months. They did not quite meet that ambitious goal, but they were delivered a few months after the Battle of Jutland in 1916. They were the world's fastest capital ships upon their commissioning.

HMS <i>Renown</i> (1916) 1916 Renown-class battlecruiser of the Royal Navy

Her construction was suspended on the outbreak of war on the grounds she would not be ready in a timely manner. Admiral Lord Fisher, upon becoming First Sea Lord, gained approval to restart her construction as a battlecruiser that could be built and enter service quickly.

Renown, and her sister HMS Repulse, were the world's fastest capital ships upon completion.

HMS <i>Repulse</i> (1916) 1916 Renown-class battlecruiser of the Royal Navy

HMS Repulse was one of two Renown-class battlecruisers built for the Royal Navy during the First World War. Originally laid down as an improved version of the Revenge-class battleship, her construction was suspended on the outbreak of war because she would not be ready in time. Admiral Lord Fisher, upon becoming First Sea Lord, gained approval for her to resume construction as a battlecruiser that could be built and enter service quickly. The Director of Naval Construction (DNC), Eustace Tennyson-d'Eyncourt, quickly produced an entirely new design to meet Admiral Lord Fisher's requirements and the builders agreed to deliver the ship in 15 months. They did not quite meet that ambitious goal, but the ship was delivered a few months after the Battle of Jutland in 1916. Repulse and her sister ship Renown were the world's fastest capital ships upon completion.

HMS <i>Hood</i> Admiral-class battlecruiser

HMS Hood was a battlecruiser of the Royal Navy (RN). Hood was the first of the planned four Admiral-class battlecruisers to be built during the First World War. Already under construction when the Battle of Jutland occurred in mid-1916, that battle revealed serious flaws in her design, and despite drastic revisions she was completed four years later. For this reason, she was the only ship of her class to be completed, as the Admiralty decided it would be better to start with a clean design on succeeding battlecruisers, leading to the never-built G-3 class. Despite the appearance of newer and more modern ships, Hood remained the largest warship in the world for 20 years after her commissioning, and her prestige was reflected in her nickname, "The Mighty Hood".

<i>Courageous</i>-class battlecruiser Ship class built for the Royal Navy during the First World War

The Courageous class consisted of three battlecruisers known as "large light cruisers" built for the Royal Navy during the First World War. The class was nominally designed to support the Baltic Project, a plan by Admiral of the Fleet Lord Fisher that was intended to land troops on the German Baltic Coast. Ships of this class were fast but very lightly armoured, with only a few heavy guns. They were given a shallow draught, in part to allow them to operate in the shallow waters of the Baltic but also reflecting experience gained earlier in the war. To maximize their speed, the Courageous-class battlecruisers were the first capital ships of the Royal Navy to use geared steam turbines and small-tube boilers.

HMS <i>Furious</i> (47) 1917 Royal Navy Courageous-class battlecruiser later converted into an aircraft carrier

HMS Furious was a modified Courageous-class battlecruiser built for the Royal Navy (RN) during the First World War. Designed to support the Baltic Project championed by the First Sea Lord, Lord Fisher, the ship was very lightly armoured and designed with a main battery of only two 18-inch guns. Furious was modified as an aircraft carrier while under construction. Her forward turret was removed and a flight deck was added in its place, such that aircraft had to manoeuvre around the superstructure to land. Later in the war, the ship had her rear turret removed and a second flight deck installed aft of the superstructure, but this was less than satisfactory due to air turbulence. Furious was briefly laid up after the war before she was reconstructed with a full-length flight deck in the early 1920s.

HMS <i>Nelson</i> (28) 1927 Nelson-class battleship of the Royal Navy

HMS Nelson was the name ship of her class of two battleships built for the Royal Navy in the 1920s. They were the first battleships built to meet the limitations of the Washington Naval Treaty of 1922. Entering service in 1927, the ship spent her peacetime career with the Atlantic and Home Fleets, usually as the fleet flagship. During the early stages of World War II, she searched for German commerce raiders, missed participating in the Norwegian Campaign after she was badly damaged by a mine in late 1939, and escorted convoys in the Atlantic Ocean.

HMS <i>Eagle</i> (1918) Aircraft carrier of 1918

HMS Eagle was an early aircraft carrier of the Royal Navy. Ordered by Chile during the South American dreadnought race as the Almirante Latorre-class battleship Almirante Cochrane, she was laid down before World War I. In early 1918 she was purchased by Britain for conversion to an aircraft carrier; this work was finished in 1924. Her completion was delayed by labour troubles and the possibility that she might be repurchased by Chile for reconversion into a battleship, as well as the need for comparative trials to determine the optimum layout for aircraft carriers. The ship was initially assigned to the Mediterranean Fleet and then later to the China Station, spending very little time in home waters other than for periodic refits.

HMS <i>Ramillies</i> (07) 1917 Revenge-class battleship of the Royal Navy

HMS Ramillies was one of five Revenge-class super-dreadnought battleships built for the Royal Navy during the First World War. They were developments of the Queen Elizabeth-class battleships, with reductions in size and speed to offset increases in the armour protection whilst retaining the same main battery of eight 15-inch (381 mm) guns. Completed in late 1917, Ramillies saw no combat during the war as both the British and the German fleets had adopted a more cautious strategy by this time owing to the increasing threat of naval mines and submarines.
