50 029 Renown and 50 030 Repulse, like other Class 50 members, are named after Royal Navy ships. The potted histories and photographs below are taken from the US Naval Historical Center.

HMS Renown

HMS Renown, lead ship of a class of two 26,500-ton battlecruisers, was built at Glasgow, Scotland. Completed in September 1916, she served with the Grand Fleet in the North Sea during the remaining two years of World War I. In 1920-21, following a refit, she carried the Prince of Wales on a voyage to Australia and America. During 1923-26, she was extensively refitted to increase her protection against gunfire and torpedoes. After a decade of further service, Renown was again reconstructed, greatly changing her appearance and giving her a modern anti-aircraft gun battery, much enhanced aircraft-handling facilities and up-to-date gunfire controls. This work was completed in September 1939, just after the outbreak of the Second World War.

Renown's high speed made her a valuable asset during World War II. In late 1939, she was sent to the South Atlantic to search for the German armored ship Admiral Graf Spee. She covered minelaying operations along the Norwegian coast in early April 1940 and, on the 9th of that month, engaged the German battleships Scharnhorst and Gneisenau, damaging the latter. Later in 1940 and into 1941, she operated with Force "H", based at Gibraltar to provide strategic presence in both the Atlantic and Mediterranean. While with Force "H", she participated in a bombardment of Genoa, Italy, in February 1941. After Home Fleet service in 1942-43, Renown was sent to join the Eastern Fleet in the Indian Ocean. Operating from Ceylon in 1944-45, she helped contain the Japanese in the East Indies. HMS Renown had brief post-war service in British waters and was sold for scrapping in March 1948.

HMS Repulse - Battlecruiser

HMS Repulse, a 26,500-ton Renown class battlecruiser, was built at Clydebank, Scotland. Completed in August 1916, she joined the Grand Fleet following post-trials modifications and operated in the North Sea for the remainder of World War I. The light protection of this class of two battlecruisers was a considerable cause for concern and, soon after the Armistice, Repulse received an extensive refit. This significantly increased her armor, and her displacement, which rose some six-thousand tons. The work was completed in 1922, after which the ship began a peacetime career of fleet operations and long-distance cruises.

In 1933-36, Repulse was again modernized, emerging with improved deck armor, a hangar and catapult for aircraft, and a greatly increased anti-aircraft gun battery. She operated with the Home Fleet in the North Sea and Atlantic during the first two years of the Second World War, taking part in the pursuit of the German battleship Bismarck in May 1941. Later in the year she was sent to the Far East, accompanying the new battleship Prince of Wales. The two ships arrived at Singapore just before Japan began the Pacific War. As soon as hostilities commenced, both steamed northwards to intercept a reported invasion force. While returning to Singapore on 10 December 1941, Repulse and Prince of Wales were attacked by Japanese high-level bombers and torpedo planes. Repulse was moderately damaged by bombs early in the action and was later hit by several torpedoes. After receiving this heavy underwater damage, she sank rapidly, followed less than an hour later by the Prince of Wales.
