Hood

Design

The inception of what was to become HMS Hood began as a request to the Director of Naval Construction to design a class of ships that would succeed the Queen Elizabeth-class super dreadnoughts and would incorporate the latest design of underwater torpedo protection. After a few proposed designs, an intervention by Admiral of the Fleet John Jellicoe — First Sea Lord of the Royal Navy — argued a change of the design to that of a battlecruiser in order to provide a response to the new Mackensen-class battlecruisers being constructed by the Imperial German Navy at the time. After a second round of design proposals that prioritized speed over protection, design “No. 2” as it was known, became selected as the plan for the Admiral-class battlecruisers we know today.

HMS Hood was planned at 860 feet in length: a long ship by design, as there was an emphasis on hull elongation in order to reduce the draft of the ship. The goal was to improve underwater integrity and to increase her freeboard, with the intent of making her a more stable artillery platform. Additionally, she incorporated the new design of anti-torpedo blisters approved by the Admiralty. A two-layer system — an outer layer filled with air, and inner layer filled with crushing tubes — was utilized in order to both absorb and spread out the shock of explosions. For additional torpedo protection, these blisters were positioned over the fuel oil tanks, which were designed watertight and separate from the rest of the ship. As initially designed, Hood was to have eight (8) inches of sloped main belt armor and one-and-a-half (1.5) to two (2) inches of horizontal protection to match the survivability of the Queen Elizabeth class. The outcome of the Battle of Jutland necessitated a redesign of Hood’s armor protection. Her belts and barbettes were increased to twelve (12) inches, and her primary decks were increased to three (3) inches of thickness.

While these choices seemed correct in order to improve her survivability, history would prove that the measures taken were not adequate. As with her predecessors, Hood still possessed deplorable protection against plunging fire; in fact, Hood did not possess an armored main deck, only multiple decks of reinforced thickness. This was adequate for shells that used a direct fuse, but not for delayed-fuse shells that came into service by the Second World War. Another inherent fault of British battlecruiser designs: the magazines were placed on top of the shell rooms, which made them a hazard if damaged. In the end, Hood became another victim of her pedigree.

True to her nature, Hood was a fast ship, rated for 32 knots at top speed. To achieve such speeds, the designers took advantage of her immense size and mounted no less than 24 Admiralty boilers that fed four multi-geared turbines. She was an innovator, being the first ship in the Royal Navy to use small-tube boilers that gave her more power for less weight. In fact, she generated 30% more power than the Renown class. At over 140,000 shaft horsepower, she was the most powerful ship in the world upon her completion, but such performance paid a price: at top speed she was horrendously fuel-inefficient, burning 70 tons of fuel per hour.

Hood’s main battery was comprised of the staple of Royal Navy capital ships of the era: eight (8) 15-inch Mark I rifles in four twin-gun Mark II turrets, arranged in super-firing pairs fore and aft. The Mark II turrets were an improved mount; they could elevate the barrels up to +30° in order to increase range. The 15-inch Mark I rifles themselves were a direct enlargement of the earlier 13.5-inch Mark V guns. The change in armament reflected a change in priority: the 15-inch guns traded shell velocity for shell weight, under the belief that penetration would not be compromised due to increased hitting power.

HMS Hood, the lead – and only – ship of the Admiral-class battlecruisers was laid down 1 September 1916 at John Brown & Co. Shipyards in Clydebank, Scotland. She was originally laid down on the 31st May 1916, but the Battle of Jutland that day saw her construction suspended as the design for the battlecruisers was up-armoured. She was launched 22 August 1918, and commissioned into the Royal Navy on 15 May 1920. What was revealed was a beautiful amalgamation of old and new: she still retained a tripod mast and hand-operated secondary guns, but also incorporated novelties like a fully enclosed bridge, and fire-control from elevated directors. She also brought back the clipper-bow, something not seen on Royal Navy ships since the 1860s.

Service

Shortly after commissioning, HMS Hood became the flagship of the Battlecruiser Squadron of the Atlantic Fleet. Much of Hood’s service during the 1920’s was goodwill visits, regular patrols and circumnavigations. Hood became the poster ship of the Royal Navy, dubbed “The Mighty Hood”, sailing around the world as the embodiment of British pride and power. She participated in a circumnavigation from east to west via the Panama Canal alongside the battlecruiser HMS Repulse and several Danae-class cruisers starting in November 1923, returning home 10 months later after having visited South Africa, India, Australia, New Zealand, Canada, the United States, and several smaller colonies en route. While in Australia in 1924, she escorted the battlecruiser HMAS Australia out to where she was to be scuttled in compliance with the Washington Naval Treaty. After visiting Lisbon, Portugal, in 1925 to participate in Vasco da Gama celebrations, Hood spent the rest of the decade largely performing winter training and exercises in the Mediterranean.

Hood’s first major refit occurred from 1929 to 1931, resuming her role as flagship of the Battlecruiser Squadron afterwards. Her squadron made a Caribbean cruise in 1932, followed by a brief refit, and then another brief refit in 1934. The first major damage Hood sustained was from an accidental ramming from the battlecruiser HMS Renown in early 1935, resulting in the destruction of her left outer propeller and an 18-inch dent. Following repairs, she was the center of attention at King George V’s Silver Jubilee Fleet Review in August 1935. She was attached to the Mediterranean fleet shortly afterwards, stationed in Gibraltar at the outbreak of the Second Italo-Abyssinian War, later being formally transferred to the Mediterranean Fleet after the beginning of the Spanish Civil War. Hood’s last refit was in 1937, but while her constant service made her the most battle-worthy fast capital ship in the Royal Navy, her material condition had degraded, and by the mid to late 1930’s she was in bad need of a lengthy overhaul. Her next big modernization was planned for 1941 to bring her up to date with the other modernized World War I-era capital ships, but the outbreak of World War II in 1939 made it impossible to remove her from service.

Shortly before the outbreak of World War II, Hood was assigned to the Home Fleet’s Battlecruiser Squadron, and after the war broke out later that year, she vigorously patrolled the seas around Iceland and the Faroe Islands to protect convoys and intercept German merchant raiders and blockade runners. Hood’s first major combat sortie was her participation in Operation Catapult in 1940: the destruction of the Vichy French fleet at Mers-el-Kébir. Joining Force H as the flagship alongside the aircraft carrier HMS Ark Royal, the results of Hood’s fire upon the French warships is not entirely known, but it is confirmed that she damaged the French battleship Dunkerque enough to force her to beach herself. Hood was later relieved by Renown as the flagship of Force H, after returning to Scapa Flow. Hood was later positioned at Rosyth alongside the battleships HMS Nelson and HMS Rodney, to be in the prime position to intercept a German invasion fleet. Hood sortied from Rosyth twice in 1940, once in late October to intercept the German panzerschiffe Admiral Scheer, and on Christmas Eve to locate the heavy cruiser Admiral Hipper, but she failed to find either ship.

In January 1941, Hood received what was to be her last refit. Even after this refit she was still in poor condition, but the Royal Navy couldn’t afford to keep in the drydocks for too long until more of the new King George V-class battleships came into service. Hood was ordered to intercept the German battleships Scharnhorst and Gneisenau upon completion of her refit, but again was unsuccessful in finding the pair. She patrolled the Bay of Biscay to prevent a breakout from the German ships anchored in Brest, before moving to the Norwegian Sea in April following false reports that the German battleship Bismarck had sailed from Germany. Hood had returned to Scapa Flow by early May, again poised to receive the order to sail again.

On 24 May 1941, that order came. The day before, the heavy cruisers HMS Norfolk and HMS Suffolk sighted the German warships Bismarck and Prinz Eugen in the Denmark Strait between Greenland and Iceland. Hood — together with the newly-commissioned battleship HMS Prince of Wales — steamed to intercept the pair of German warships before they could break through to the open Atlantic. Hood and Prince of Wales sighted Bismarck and Prinz Eugen at 05:37, but the Germans were already aware of their presence. Hood’s fight during the conflict that came to be known at the Battle of the Denmark Strait lasted less than an hour. The British ships opened fire on the German duo, with the Germans returning fire shortly afterwards, both ships focusing on Hood. Prinz Eugen likely scored the first hit on Hood, striking amidships and starting a large fire from the ready-use ammunition and rockets for her AA guns and UP mountings. At 06:00, Hood turned to bring her full broadside to bear on the Germans, before being struck by Bismarck’s fifth salvo from a range of approximately 16,650 meters. Shortly after, a enormous jet of flame erupted from the vicinity of the mainmast, before Hood catastrophically exploded with a loss of 1,415 men; there were a mere 3 survivors. One of Bismarck’s shells most likely had penetrated her upper armoured belt and set off a magazine explosion in Hood’s after magazines. Prince of Wales, now outnumbered and struggling to fight from a mix of mechanical failures and sustained damage, was forced to withdraw, while Bismarck — not undamaged herself — attempted to retreat to German-occupied France. In the duel against infamous Bismarck and her escort Prinz Eugen, the pride and joy of the Royal Navy was lost with nearly all hands, including her captain, Ralph Kerr, and Vice-Admiral Lancelot Holland.

The blow to British morale caused by the loss of Hood was significant: the most well-known ship of the Royal Navy had been destroyed in mere minutes with virtually no survivors. Enraged by her loss, Prime Minister Winston Churchill ordered the British Admiralty to find and destroy Bismarck at all costs. “I don’t care how you do it,” he said, “[but] you must sink the Bismarck.” Three days later, the Royal Navy fulfilled Churchill's wishes; too late, unfortunately, to save ill-fated HMS Hood.

Historical Inaccuracies

• Hood is represented in game by her mid 1941 self, as sunk. Not represented are her earlier pre-WW2 conditions, armed with 5.5-inch (140 mm) secondary guns.
• Hood was officially classified as a Battlecruiser, though her specifications are closer to those of Battleships.
• Hood had a top speed of 32.07kn normally, but in 1941, this was only 28.8kn as her engines were in dire need of an overhaul.
• The unrotated projectiles (UP) were unreliable and ineffective in operation; aircraft could avoid the wires and winds could blow the projectiles back onto the ship which fired them. There are no records of UPs shooting down any aircraft.
• The Mk.II turret for the 15"/42 Mk.I gun had a traverse rate of 2°/s, but in game this is buffed to 5°/s.
• Hood comes default with a two tone grey camouflage scheme; she was actually painted in overall dark grey for most of her career. The two tone camouflage scheme is a toned down scheme of that worn by HMS Repulse.
