HMS Prince of Wales was a King George V-class battleship of the Royal Navy that was built at the Cammell Laird shipyard in Birkenhead. Despite being sunk less than a year after she was commissioned, Prince of Wales had an extensive battle history, first seeing action in August 1940 while still being outfitted in her drydock when she was attacked and damaged by German aircraft. In her brief career, she was involved in several key actions of the Second World War, including the May 1941 Battle of the Denmark Strait where she scored three hits on the German battleship Bismarck, forcing Bismarck to abandon her raiding mission and head to port for repairs. Prince of Wales later escorted one of the Malta convoys in the Mediterranean, during which she was attacked by Italian aircraft. In her final action, she attempted to intercept Japanese troop convoys off the coast of Malaya as part of Force Z when she was sunk by Japanese aircraft on 10 December 1941, two days after the attack on Pearl Harbor.

Operation Rheinübung was the last sortie into the Atlantic by the new German battleship Bismarck and heavy cruiser Prinz Eugen on 18–27 May 1941, during World War II. This operation aimed to block Allied shipping to the United Kingdom as the previously successful Operation Berlin had done. After Bismarck had sunk HMS Hood during battle of the Denmark Strait, it culminated with the sinking of Bismarck, while Prinz Eugen escaped to port in occupied France. From that point on, Germans would rely only on U-boats to wage the Battle of the Atlantic.
