HMS Royal Sovereign (05)



HMS Royal Sovereign (pennant number 05) was a Revenge-class (also known as Royal Sovereign and R-class) battleship of the Royal Navy displacing 28,000 metric tons (27,560 long tons; 30,860 short tons) and armed with eight 15-inch (381 mm) guns in four twin 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 war, but did not see action. In the early 1930s, she was assigned to the Mediterranean Fleet and based in Malta.

Unlike the Queen Elizabeth-class battleships, Royal Sovereign and her sisters were not modernised during the interwar period. Only minor alterations to her anti-aircraft battery were effected before the outbreak of World War II in September 1939. Assigned to the Home Fleet, she was tasked with convoy protection until May 1940, when she returned to the Mediterranean Fleet. She was present during the Battle of Calabria in July 1940, but her slow speed prevented her from engaging the Italian battleships. By March 1942, she was assigned to the Eastern Fleet in the Indian Ocean, but after the Indian Ocean raid by Admiral Nagumo's Kido Butai, she was withdrawn to eastern Africa to escort convoys. In January 1944, she returned to Britain, and in May the Royal Navy transferred the ship to the Soviet Navy, where she was renamed Arkhangelsk. She then escorted Arctic convoys into Kola until the end of the war. The Soviets returned the ship in 1949, after which she was broken up for scrap. {| class="toc" id="toc"

[edit] Description
Line-drawing of Royal SovereignMain article: Revenge class battleshipRoyal Sovereign was 624 feet 3 inches (190.27 m) long overall and had a beam of 88 ft 6 in (26.97 m) and a draught of 28 ft 6 in (8.69 m). She had a designed displacement of 28,000 tonnes (27,558 long tons; 30,865 short tons) and with a full combat load, she displaced 31,000 t (30,510 long tons; 34,172 short tons). She was powered by four Parsons steam turbines with steam from eighteen oil-fired boilers. These were rated at 40,000 shaft horsepower (29,828 kW) and a top speed of 23 knots (42.6 km/h; 26.5 mph). She had a range of 4,200 nautical miles (7,778 km; 4,833 mi) at a cruising speed of 10 kn (18.5 km/h; 11.5 mph).[1]

The ship was equipped with eight BL 15-inch Mk I guns in four twin turrets, in superfiring pairs fore and aft of the superstructure, designated 'A', 'B', 'X', and 'Y' from front to rear. Fourteen BL 6-inch Mk XII guns were mounted in casemates along the broadside of the vessel amidships. As built, her anti-aircraft armament consisted of two QF 3-inch 20 cwt Mk I[Note 1] guns.[1]

In August-September 1924, the 3-inch guns had been replaced by a pair of QF 4-inch Mk V guns,[2] and another pair was added during the ship's 1927–28 refit.[3] These were replaced by eight QF 4-inch Mk XVI guns in twin turrets during Royal Sovereign ' s 1937–38 refit. A pair of eight-barrel 2-pounder "pom-poms" were added in 1932 abreast the funnel, and two four-barrel "pom-poms" were added in early 1942 atop 'B' and 'X' turrets.[4] Ten 20 mm Oerlikon guns were also added in 1941. Another six were added in 1943.[5] Royal Sovereign was initially equipped with four 21 in (530 mm) torpedo tubes submerged on her beam,[1] though the after pair were removed in 1932. The forward pair were also removed in 1937–1938, during the ship's last prewar refit.[6]

[edit] Fire control
Royal Sovereign 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 March 1917.[7] A 30-foot (9.1 m) rangefinder replaced the smaller one originally fitted in 'X' turret in 1919. Similarly, another large rangefinder was fitted in 'B' turret during the ship's 1921–22 refit. A simple high-angle rangefinder was added above the bridge during that same refit.[8]

About 1930–31, a High-Angle Control System (HACS) Mk I director replaced the high-angle rangefinder on the spotting top.[9] During the 1932 refit two positions for 2-pounder "pom-pom" anti-aircraft directors were added on new platforms abreast and below the fire-control director in the spotting top. In the 1937–38 refit a HACS Mark III director replaced the Mk I in the spotting top and another was added to the torpedo-control tower aft.[10] By 1942, a Type 279 air warning radar, a Type 273 surface-search radar, a Type 284 gunnery radar and two Type 285 anti-aircraft gunnery radars were installed. By September 1943, the Type 284 radar had been replaced by an improved Type 284B and two Type 282 radars had been fitted for the "pom-poms".[11]

[edit] Protection
Royal Sovereign ' s armour scheme was based on that of the Queen Elizabeth class with a uniform waterline belt 13 inches (330 mm) thick, unlike the older ship's armour that tapered to 8 inches (203 mm) below the waterline. The armoured belt consisted of face-hardened Krupp cemented armour (KC) with its maximum thickness between 'A' and 'Y' barbettes and thinned to four to six 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 four to six inches thick ran at an angle from the ends of the thickest part of the waterline belt to 'A' and 'Y' barbettes.[12]

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 four to six inches thick below it. The forecastle deck was 1 inch (25 mm) thick, while the upper deck was 1–1.5 inches (25–38 mm) in thickness.[13] The main deck was 2 inches (51 mm) thick over the magazines and machinery spaces and one inch elsewhere, except for the 2-inch-thick slope that met the bottom of the main belt. The middle deck was one inch thick over 'Y' magazine, but increased to two to four inches over the steering machinery. The lower deck armour was forward of 'A' barbette and ranged in thickness from 1–2.5 inches (25–64 mm).<sup class="reference" id="cite_ref-rr36_14-0">[14] The main conning tower had 13 inches of armour on the sides with a 3-inch (76 mm) roof. The torpedo control tower in the rear superstructure had six inches of armour protecting it.<sup class="reference" id="cite_ref-15">[15] After the Battle of Jutland, 1 inch (25 mm) of high-tensile steel was added to the main deck over the magazines and additional anti-flash equipment was added in the magazines.<sup class="reference" id="cite_ref-16">[16]

To protect against underwater explosions, the ship was fitted with longitudinal bulkheads 1 to 1.5 inches thick that ran from the forward to the rear magazines. During her 1921 refit, Royal Sovereign was fitted with an anti-torpedo bulge that ran the length of the ship between the fore and aft barbettes. It was divided into a water-tight empty lower compartment and an upper compartment filled with water-tight "crushing tubes" intended to absorb and distribute the force of an explosion. The space between the tubes was filled with wood and cement.<sup class="reference" id="cite_ref-17">[17]

[edit] Aircraft
The ship was fitted with flying-off platforms mounted on the roofs of 'B' and 'X' turrets in 1918, from which fighters and reconnaissance aircraft could launch.<sup class="reference" id="cite_ref-18">[18] During her 1932 refit, the platforms were removed from the turrets and a trainable catapult was installed on her quarterdeck, along with a crane to recover a seaplane. The catapult and crane were removed about 1936.<sup class="reference" id="cite_ref-19">[19]

[edit] First World War
Royal Sovereign firing her 15-inch (381 mm) guns during gunnery practice late in the First World WarRoyal Sovereign was laid down on 15 January 1914 at the Portsmouth Dockyard. The ship was launched on 29 April 1915 and commissioned in May 1916.<sup class="reference" id="cite_ref-GG35_0-3">[1] She was still working up during the Battle of Jutland and the end of the month, and so she was not present during the engagement.<sup class="reference" id="cite_ref-20">[20] On 30 May 1916, three weeks after her commissioning, Royal Sovereign was present in Scapa Flow when the fleet commander, Admiral John Jellicoe ordered the fleet to sea. Jellicoe purposely left Royal Sovereign in port due to the inexperience of her crew; as a result, she missed the Battle of Jutland the following day.<sup class="reference" id="cite_ref-21">[21] In the months after the engagement, Royal Sovereign was quickly made ready for service with the fleet to further increase the numerical superiority of the Grand Fleet over the German High Seas Fleet.<sup class="reference" id="cite_ref-22">[22]

The Grand Fleet sortied on 18 August 1916 to ambush the High Seas Fleet while it advanced into the southern North Sea, but a series of miscommunications and mistakes prevented Jellicoe from reaching the German fleet before it returned to port. Two light cruisers were sunk by German U-boats during the operation, prompting Jellicoe to decide to not risk the major units of the fleet south of 55° 30' North due to the prevalence of German submarines and mines.<sup class="reference" id="cite_ref-23">[23] The Admiralty concurred and stipulated that the Grand Fleet would not sortie unless the German fleet was attempting an invasion of Britain or there was a strong possibility it could be forced into an engagement under suitable conditions.<sup class="reference" id="cite_ref-24">[24]

In April 1918, the High Seas Fleet again sortied, to attack British convoys to Norway. They enforced strict wireless silence during the operation, which prevented Room 40 cryptanalysts from warning the new commander of the Grand Fleet, Admiral David Beatty. The British only learned of the operation after an accident aboard the battlecruiser SMS Moltke forced her to break radio silence to inform the German commander of her condition. Beatty then ordered the Grand Fleet to sea to intercept the Germans, but he was not able to reach the High Seas Fleet before it turned back for Germany. This was the last time Royal Sovereign and the rest of the Grand Fleet would go to sea for the remainder of the war.<sup class="reference" id="cite_ref-25">[25] On 21 November 1918, following the Armistice, the entire Grand Fleet left port to escort the surrendered German fleet into internment at Scapa Flow.<sup class="reference" id="cite_ref-26">[26]

[edit] Inter-war period
The Royal Marines detachment assigned to Royal Sovereign left the ship on 21 June 1919 to conduct exercises. The ship meanwhile went into drydock at Invergordon in September. Post-war demobilization in 1919 saw some 500 men leave the ship while she was in dock. Upon returning to service in late 1919, the ship was assigned to the 1st Battle Squadron of the Atlantic Fleet. Conflicts between Greece and the crumbling Ottoman Empire prompted the Royal Navy to deploy a force to the eastern Mediterranean. In April 1920, Royal Sovereign and her sister ship  Resolution  steamed to the region via Malta.<sup class="reference" id="cite_ref-S12_27-0">[27] While in the Ottoman capital Constantinople, Royal Sovereign and the other British warships took on White émigré fleeing the Communist Red Army. Among those refugees aboard Royal Sovereign was a princess of the Galitzine family.<sup class="reference" id="cite_ref-28">[28]

The 1922 Washington Naval Treaty cut the battleship strength of the Royal Navy from forty ships to fifteen. The remaining active battleships were divided between the Atlantic and Mediterranean Fleets and conducted joint operations annually.<sup class="reference" id="cite_ref-29">[29] Royal Sovereign remained with the Atantic Fleet through 1926.<sup class="reference" id="cite_ref-S12_27-1">[27] On 4 October 1927, the ship was placed in reserve to effect a major refit. Four new rangefinders and eight searchlights were installed.<sup class="reference" id="cite_ref-30">[30] On 15 May 1929, the refit was finished, and the ship was assigned to the 1st Battle Squadron of the Mediterranean Fleet. The squadron consisted of Royal Sovereign, her sisters Resolution and  Revenge , and  Queen Elizabeth , and based in Malta.<sup class="reference" id="cite_ref-31">[31] By the 1930s, the five ships of the Queen Elizabeth class were rotated through extensive modernisation. Royal Sovereign and her sisters, however, were smaller and slower than the Queen Elizabeth-class, and so they were not extensively modernised in the inter-war period. The only changes made were augmentations to their anti-aircraft batteries.<sup class="reference" id="cite_ref-32">[32]

Fleet exercises in 1934 were carried out in the Bay of Biscay, followed by a fleet regatta in Navarino Bay off Greece. In 1935, the ship returned to Britain for the Jubilee Fleet Review for King George V. In August 1935, Royal Sovereign was transferred to the 2nd Battle Squadron of the Atlantic Fleet, where she served as the flagship of Rear Admiral Charles Ramsey.<sup class="reference" id="cite_ref-33">[33] The ship served as a training vessel until 2 June 1937, when she was again placed in reserve for a major overhaul. This lasted until 18 February 1938, after which she returned to the 2nd Battle Squadron.<sup class="reference" id="cite_ref-34">[34] In 1939, King George VI made a state visit to Canada; Royal Sovereign and the rest of the fleet escorted his ship halfway across the Atlantic and met it on the return leg of the voyage.<sup class="reference" id="cite_ref-35">[35]

In early 1939, the Admiralty considered plans to send Royal Sovereign and her four sisters to Asia to counter Japanese expansionism. They reasoned that the then established "Singapore strategy", which called for a fleet to be formed in Britain to be dispatched to confront a Japanese attack was inherently risky due to the long delay. They argued that a dedicated battle fleet would allow for faster reaction. The plan was abandoned, however, because the new King George V class battleships would not begin to enter service until 1941.<sup class="reference" id="cite_ref-36">[36] In the last weeks of August 1939, the Royal Navy began to concentrate in wartime bases as tensions with Germany rose. Royal Sovereign steamed to Invergordon, where she joined her sisters Resolution and  Royal Oak ,  Rodney , and the battlecruiser  Repulse . By 31 August, the force joined  Nelson , the flagship of Admiral Charles Forbes, the commander of the Home Fleet.<sup class="reference" id="cite_ref-37">[37]

[edit] Second World War
On 31 August, the day before the German invasion of Poland, Royal Sovereign was assigned to a screening force in the Greenland-Iceland-United Kingdom gap to patrol for German merchant ships that might be attempting to reach Germany.<sup class="reference" id="cite_ref-38">[38] At the outset of war in September 1939, Royal Sovereign was assigned to the 2nd Battle Squadron of the Home Fleet.<sup class="reference" id="cite_ref-39">[39] She was assigned to the North Atlantic Escort Force, which was based in Halifax, Nova Scotia, and was tasked with protecting convoys to Britain. Upon returning to Plymouth, she underwent a short refit. In May 1940, she moved to the Mediterranean Fleet.<sup class="reference" id="cite_ref-K37_40-0">[40] There she was based in Alexandria with the battleships  Warspite ,  Malaya , and  Valiant , under the command of Admiral Andrew Cunningham.<sup class="reference" id="cite_ref-41">[41] On 25–27 June, she and her sister ship HMS Ramillies escorted two convoys from Alexandria to Malta.<sup class="reference" id="cite_ref-42">[42] On 28 June, aerial reconnaissance located Italian destroyers off Zakinthos; Admiral John Tovey took the 7th Cruiser Squadron. Royal Sovereign was left behind due to her slow speed.<sup class="reference" id="cite_ref-43">[43] Cunningham spit his fleet into three groups; Royal Sovereign and Malaya were the core of Group C.<sup class="reference" id="cite_ref-44">[44] She was present at the Battle of Calabria on July 18, but her slow speed prevented her from engaging the Italian battleships.<sup class="reference" id="cite_ref-K37_40-1">[40] Warspite bore the brunt of the action, as Royal Sovereign and Malaya lagged behind.<sup class="reference" id="cite_ref-45">[45]

In mid-August 1940, while steaming in the Red Sea, Royal Sovereign was unsuccessfully attacked by the Italian submarine  Galileo Ferraris .<sup class="reference" id="cite_ref-46">[46] Later that month, she returned to Atlantic convoy duties. These lasted until August 1941, when periodic maintenance was effected in Norfolk, Virginia.<sup class="reference" id="cite_ref-K37_40-2">[40] The Admiralty decided in May 1941 to deploy a powerful fleet to be based in Singapore to counter any Japanese attempt to invade Western colonies in Southeast Asia. Royal Sovereign and her sisters Revenge, Ramillies, and Resolution were assigned to the force. The unit was to have been assembled in Singapore by March 1942,<sup class="reference" id="cite_ref-47">[47] though Royal Sovereign reached the theatre earlier.<sup class="reference" id="cite_ref-P348_48-0">[48] At the beginning of March 1942, Royal Sovereign, the heavy cruiser  Cornwall , and several smaller vessels escorted the convoy SU.1 of twelve troopships transporting 10,090 soldiers.<sup class="reference" id="cite_ref-49">[49] The convoy departed Colombo on 1 March, bound for Australia. The convoy reached Fremantle without incident on 15 March.<sup class="reference" id="cite_ref-P348_48-1">[48]

By the end of March 1942, the Eastern Fleet had been formed, under the command of Admiral James Somerville. The fleet was centered on a pair of fleet aircraft carriers, the elderly carrier  Hermes , and five battleships, four of which were Royal Sovereign and her sisters; the fifth was Warspite. The fleet also included seven cruisers and sixteen destroyers. Despite the numerical strength of the Eastern Fleet, many of its units, including the four Revenge class battleships, were no longer front-line warships. Vice Admiral Chūichi Nagumo's powerful Kido Butai, composed of six carriers and four fast battleships, was significantly stronger than Somerville's Eastern Fleet. As a result, only the modernised Warspite could operate with the two fleet carriers; Royal Sovereign, her three sisters, and Hermes were kept away from combat to escort convoys in the Indian Ocean.<sup class="reference" id="cite_ref-J293_50-0">[50]

In late March, the code-breakers at the Far East Combined Bureau, a branch of Bletchley Park, informed Somerville that the Japanese were planning a raid into the Indian Ocean to attack Colombo and Trincomalee and destroy his fleet. He therefore divided his fleet into two groups: Force A, which consisted of the two fleet carriers, Warspite and four cruisers, and Force B, centered on Royal Sovereign and her sisters and the carrier Hermes. He intended to ambush Nagumo's fleet in a night action, the only method by which he thought he could achieve a victory. After three days of searching for the Japanese fleet without success, Somerville returned to Addu Atoll to refuel. While refueling his ships, Somerville received a report that the Japanese fleet was approaching Colombo, which they attacked the following day, on 5 April, followed by attacks on Trincomalee on 9 April.<sup class="reference" id="cite_ref-51">[51]

Following the raid in April 1942, Somerville withdrew Royal Sovereign and her three sisters to Mombasa, where they could secure the shipping routes in the Middle East and the Persian Gulf.<sup class="reference" id="cite_ref-J293_50-1">[50] Royal Sovereign and her sisters departed from Addu Atoll early on the morning on 9 April, bound for Mombasa. Here they remained stationed until September 1943,<sup class="reference" id="cite_ref-52">[52] with the exception of another long period in the dockyard in Philadelphia in late 1942. While Royal Sovereign was moored in Philadelphia, the American light cruiser USS Boise, a badly-damaged veteran of the Battle of Cape Esperance, shared a pier with her.<sup class="reference" id="cite_ref-53">[53] During the refit, the ship's deck armour was increased by 2 inches (51 mm) and four of her 6-inch (150 mm) guns were removed.<sup class="reference" id="cite_ref-54">[54] Royal Sovereign was sent back to the United States for a major overhaul in Philadelphia, from March to September 1943. She then returned to the Indian Ocean to resume her patrol duties. In January 1944, she left the Indian Ocean, bound for Britain.<sup class="reference" id="cite_ref-55">[55]

[edit] Service with the Soviet Navy
After returning to Britain, Royal Sovereign was sent to the naval base in Scapa Flow.<sup class="reference" id="cite_ref-56">[56] On 30 May 1944 she was transferred on loan to the Soviet Navy as Arkhangelsk in lieu of war reparations from Italy. The ship left Britain on 17 August 1944 as part of the escort for the convoy JW 59, which contained thirty-three merchant vessels.<sup class="reference" id="cite_ref-57">[57] Six days later, while still en route, the convoy was attacked by the U-boat  U-711 . The submarine's captain incorrectly reported hits on Arkhangelsk and a destroyer,<sup class="reference" id="cite_ref-P1534_58-0">[58] though his torpedoes had exploded prematurely.<sup class="reference" id="cite_ref-59">[59] Under the impression that they had crippled the battleship, the Germans launched several submarine attacks on the ship while she was moored in Kola. Anti-torpedo nets ensured that the attacks failed, however.<sup class="reference" id="cite_ref-P1534_58-1">[58] The Germans then planned to use six  Biber  midget submarines to attack the ship, but mechanical difficulties eventually forced the cancellation of the plan. Regardless, Arkhangelsk had already departed Kola to patrol the White Sea by the time the Bibers would have arrived.<sup class="reference" id="cite_ref-60">[60] A Soviet crew commissioned the ship on 29 August 1944 at Polyarny. Arkhangelsk was the largest ship in the Soviet fleet during the war.<sup class="reference" id="cite_ref-B3_61-0">[61] While in Soviet service, she was the flagship of Admiral Gordey Levchenko and was tasked with meeting Allied convoys in the Arctic Ocean and escort them into Kola.<sup class="reference" id="cite_ref-62">[62]

Arkhangelsk ran aground in the White Sea in late 1947; the extent of damage, if any, is unknown.<sup class="reference" id="cite_ref-m8_63-0">[63] The Soviet Navy returned the ship to the Royal Navy on 4 February 1949 after the former Italian battleship  Giulio Cesare  was transferred to the Soviet Black Sea Fleet.<sup class="reference" id="cite_ref-B3_61-1">[61] The Soviet Navy had initially sought to avoid sending the ship back, claiming that she was not sufficiently seaworthy to make the voyage back to Britain. After an inspection by a Royal Navy officer, however, the Soviet Navy agreed to return the vessel in January 1949. Upon returning to the Rosyth naval base, Royal Navy personnel thoroughly inspected the ship and found much of her equipment to be unserviceable. It appeared to the inspectors that the main battery turrets had not been rotated while the ship was in Soviet service, and were jammed on the centreline. As a result of her poor condition, she was sold for scrap.<sup class="reference" id="cite_ref-64">[64] The ship arrived at Inverkeithing, Scotland on 18 May to be broken up.<sup class="reference" id="cite_ref-m8_63-1">[63] The elevation mechanisms from her main battery gun turrets were later reused in the 250-foot (76 m) Mark I radio telescope at Jodrell Bank, Cheshire built in 1955–1957.<sup class="reference" id="cite_ref-65">[65]
