HMS Revenge (pennant number: 06) 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 was commissioned in February 1916, early enough to be worked up in time 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.

During the 1920s and 1930s, Revenge alternated 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. The ship's interwar career was otherwise uneventful. With the outbreak of the Second World War in September 1939, Revenge was used to escort convoys and transport significant quantities of the country's gold reserves to Canada as part of Operation Fish; these activities continued into 1940. She was involved in the seizure of French warships in Portsmouth after the French surrender in July 1940.

In October 1940, she conducted Operation Medium, an attack on German transport ships that had been collected along the English Channel in preparation for the since-cancelled invasion of Britain. Revenge thereafter resumed convoy escort duties until October 1941, when she was reassigned to the 3rd Battle Squadron and sent to the Far East as tensions with Japan began to rise. British naval forces were strengthened further after the start of the Pacific War in December, leading to the creation of the Eastern Fleet. Revenge and her sister ships were deemed too old to be of use against the Japanese fleet, so they were relegated to convoy escort duties in the Indian Ocean. Badly worn out by 1943, Revenge returned home, where she was removed from front-line service. Her last voyage was to carry Prime Minister Winston Churchill to the Tehran Conference in November 1943. Upon returning, she was assigned to the training establishment HMS Imperieuse, disarmed, and eventually broken up in 1948.

HMS Royal Sovereign (pennant number 05) was a Revenge-class (also known as Royal Sovereign and R-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.

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, the ship was tasked with convoy protection until May 1940, when she returned to the Mediterranean Fleet. Royal Sovereign 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, the ship was withdrawn to eastern Africa to escort convoys. In January 1944, she returned to Britain, and in May the Royal Navy transferred Royal Sovereign to the Soviet Navy, which renamed her 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.
