HMS Royal Oak was one of five Revenge-class battleships built for the Royal Navy during the First World War. Launched in 1914 and completed in 1916, Royal Oak first saw combat at the Battle of Jutland as part of the Grand Fleet. In peacetime, she served in the Atlantic, Home and Mediterranean fleets, more than once coming under accidental attack. The ship drew worldwide attention in 1928 when her senior officers were controversially court-martialled. Attempts to modernise Royal Oak throughout her 25-year career could not fix her fundamental lack of speed, and by the start of the Second World War, she was no longer suited to front-line duty.
