HMS Glorious was the second of the three s 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.

Glorious was paid off after the war, but was rebuilt as an aircraft carrier during the late 1920s. She could carry 30 per cent more aircraft than her half-sister which had a similar tonnage. After re-commissioning in 1930, she spent most of her career operating in the Mediterranean Sea. After the start of the Second World War in 1939, Glorious spent the rest of the year hunting for the commerce-raiding in the Indian Ocean before returning to the Mediterranean. She was recalled home in April 1940 to support operations in Norway. While evacuating British aircraft from Norway in June, the ship was sunk by the German battleships and in the North Sea with the loss of over 1,200 lives.

Design and description

During the First World War, Admiral Fisher was prevented from ordering an improved version of the preceding s by a wartime restriction that banned construction of ships larger than light cruisers. To obtain ships suitable for traditional battlecruiser roles, such as scouting for fleets and hunting enemy raiders, he settled on a design 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.Burt 1986, p. 303Roberts, pp. 50–51

Glorious had an overall length of , a beam of , and a draught of at deep load. She displaced at load and at deep load.Roberts, pp. 64–65 Glorious and her sisters were the first large warships in the Royal Navy to have geared steam turbines. The Parsons turbines were powered by eighteen Yarrow boilers. During the ship's abbreviated sea trials, she reached .Roberts, pp. 71, 76, 79 The ship was designed to normally carry of fuel oil, but could carry a maximum of . At full capacity, she could steam for an estimated at .Burt 1986, p. 306

Glorious carried four BL 15-inch (381 mm) Mark I guns in two twin-gun turrets, one each fore ('A') and aft ('Y'). Her secondary armament was 18 BL 4-inch (102 mm) Mark IX guns mounted in six triple mounts. These mounts had the three breeches too close together and the 23 loaders tended to interfere with one another. This negated the mount's intended high rate of fire against torpedo boats and other smaller craft.Burt 1986, p. 294 A pair of QF 3-inch (76 mm) 20 cwt"Cwt" is the abbreviation for hundredweight, 30 cwt referring to the weight of the gun. anti-aircraft guns were fitted abreast of the mainmast on Glorious. She mounted two submerged tubes for 21-inch torpedoes and 10 torpedoes were carried.

First World War

Glorious''' keel was laid down on 1 May 1915 by Harland and Wolff at their Belfast shipyard. She was launched on 20 April 1916 and completed on 14 OctoberRoberts, p. 63 at a cost of £1,967,223.Burt 1986, p. 307 During her sea trials the following month, her sister Courageous sustained structural damage while running at full speed in a rough head sea and had the damaged areas stiffened shortly afterwards to prevent a recurrence.Burt 1986, pp. 309, 313 Glorious did not suffer similar damage and did not receive her stiffening until 1918.Roberts, p. 54 Upon commissioning, Courageous served with the 3rd Light Cruiser Squadron of the Grand Fleet. After most of the 1st Cruiser Squadron was sunk at the Battle of Jutland, the squadron was re-formed with Courageous and Glorious.Parkes, p. 621 Glorious received six twin-tube torpedo mounts in mid-1917: one mount on each side of the mainmast on the upper deck and two mounts on each side of 'Y' turret on the quarterdeck.McBride, p. 109Burt 1986, p. 314

On 16 October 1917 the Admiralty received word of German ship movements, possibly indicating some sort of raid. Admiral Beatty, 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 ordered to sea, but were sent to reinforce the 2nd Light Cruiser Squadron patrolling the central part of the North Sea later that day.Newbolt, pp. 150–151 Two German light cruisers slipped through the gaps in the British patrols and destroyed a convoy bound for Norway during the morning of 17 October, but the British warships received no word 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.Newbolt, pp. 156–157

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 10 small ships and the Admiralty decided on a larger operation to destroy the minesweepers and their light cruiser escorts. 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.Newbolt, pp. 164–165

The German ships, four light cruisers of II Scouting Force, eight destroyers, three divisions of minesweepers, eight sperrbrecher (cork-filled trawlers) and two trawlers to mark the swept route, were spotted at 7:30 am,The times used in this section are in UTC, which is one hour behind CET, which is often used in German works. silhouetted by the rising sun. Courageous and the light cruiser opened fire with their forward guns seven minutes later. The Germans responded by laying a smoke screen and this made spotting targets very difficult. The British continued in pursuit, but lost track of most of the smaller ships in the smoke and concentrated fire on the light cruisers as opportunity permitted. One 15-inch shell hit a gun shield of , but it did not affect her speed. At 8:33 the left-hand gun in Gloriouss forward turret was wrecked when a shell detonated inside the gun barrel. At 9:30 the 1st Cruiser Squadron broke off their pursuit to avoid a minefield marked on their maps. The ships turned south, playing no further role in the battle.McBride, pp. 110–112 Glorious required five days of repairs to fix damage caused by premature detonation and her own muzzle blast.McBride, p. 115 She fired 57 15-inch and 213 four-inch shells during the engagement.Campbell 1978, p. 66Glorious received flying-off platforms on top of her turrets in 1918. A Sopwith Camel was carried on the rear turret and a Sopwith 1½ Strutter on the forward turret.Campbell 1978, p. 67 On 5 November 1918, Glorious was anchored off Burntisland in the Firth of Forth together with the seaplane tender and the battleship when a sudden Force 10 squall caused Campania to drag her anchor and collide first with Royal Oak and then with Glorious. Both Royal Oak and Glorious suffered only minor damage, but Campania was holed by her collision with Royal Oak. Campania′s engine rooms flooded, and she settled by the stern and sank five hours later without loss of life.Glorious was present at the surrender of the German High Seas Fleet on 21 November 1918. She was placed in reserve at Rosyth, Scotland, on 1 February 1919 and served as a turret drill ship, being also flagship of the rear-admiral commanding the Devonport Reserve between 1921 and 1922.Burt 1993, p. 315

Conversion The Washington Naval Treaty of 1922 limited the amount of capital ship tonnage and the Royal Navy was forced to scrap many of its older battleships and battlecruisers. However up to of existing ships could be converted into aircraft carriers, for which the Courageous-class ships' large hulls and high speeds made them ideal candidates. Glorious began her conversion at Rosyth in 1924, and was towed to Devonport where she was completed on 24 February 1930. During the ship's post-conversion sea trials, she reached .Burt 1993, pp. 273, 284–285 Her 15-inch turrets were placed into storage and later reused during the Second World War for , the world's last battleship to be built.Raven and Roberts, p. 321

Her new design improved on her half-sister 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, each level high and long, was built on top of the remaining hull; the upper hangar level opened on to a short flight deck, below and forward of the main flight deck. The lower flying-off deck improved launch and recovery cycle flexibility until heavier fighters requiring longer takeoff rolls made the lower deck obsolete in the 1930s.Brown, p. 2 Two 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 as islands had been found not to contribute significantly to turbulence. By 1939 the ship could carry of petrol for her aircraft.Friedman, pp. 103, 105–106Glorious received a dual-purpose armament of sixteen QF 4.7-inch (120 mm) Mark VIII guns in single mounts. One mount was on each side of the lower flight deck and a pair was on the quarterdeck. The remaining twelve mounts were distributed along the sides of the ship.Burt 1993, pp. 274–278 During her 1935 refit, the ship received three octuple QF two-pounder (40 mm) "pom-pom" mounts, one on each side of the flying-off deck, forward of the 4.7-inch guns, and one behind the island on the flight deck. She also received a single quadruple mount for water-cooled Vickers machineguns for anti-aircraft use.Burt 1993, pp. 165, 278, 281

The ship recommissioned on 24 February 1930 for service with the Mediterranean Fleet, but was attached to the Home Fleet from March to June 1930. She relieved Courageous in the Mediterranean Fleet in June 1930 and remained there until October 1939. In a fog on 1 April 1931 Glorious rammed the French ocean liner amidships while steaming at . The impact crumpled of the flying-off deck and killed 1 seaman aboard Glorious and 24 passengers and crew aboard Florida.Hayward 1998, p. 47Treasure Jones, pp. 57–62 The ship was forced to put into Gibraltar for temporary repairs. She had to sail to Malta for permanent repairs which lasted until September 1931. Sometime in the early 1930s, transverse arresting gear was installed. She was refitted at Devonport from July 1934 to July 1935 where she received two hydraulic accelerators (catapults) on her upper flight deck, which was also extended to the rear, her quarterdeck was raised one deck and she received her multiple pom-pom mounts. Glorious participated in the Coronation Fleet Review at Spithead on 20 May 1937 for King George VI before returning to the Mediterranean.Burt 1993, pp. 281, 285
