HMS Belfast survived a broken keel and a government scrapping order
Less than four months into the Second World War, a magnetic mine snapped HMS Belfast's keel in the Firth of Forth. Many assumed she was finished. Instead she was rebuilt, fought from the Arctic to Normandy, and now floats beside Tower Bridge as a museum after a private trust rescued her from the breakers.
Belfast was Britain's answer to a naval arms race. Japan's Mogami-class cruisers carried fifteen 6-inch guns, and the Admiralty wanted comparable punch without impractical turret layouts. It settled on four improved triple turrets, which also allowed thicker deck armour, producing the heavier Edinburgh subclass. Harland and Wolff laid her keel on 10 December 1936, and she slid into the water on 17 March 1938, fittingly Saint Patrick's Day, as the first Royal Navy ship named after Northern Ireland's capital.
Commissioned on 5 August 1939, she joined the blockade of Germany and in October captured the German liner Cap Norte, disguised as a Swedish ship, earning her crew prize money. The mine struck on 21 November. Repairs took more than two years, and she returned in November 1942 with better radar, armour and guns. She escorted Arctic convoys to the Soviet Union, helped sink the battleship Scharnhorst at the Battle of North Cape in December 1943, and supported the Normandy landings in June 1944, later serving in the Korean War.
At full design her twelve main guns could together fire up to 96 rounds a minute, and two Walrus seaplanes launched from a catapult for scouting. She could reach 32.5 knots and cover 8,664 nautical miles at a steady 13.
After entering reserve in 1963, she faced scrapping. A joint committee judged preservation practical in 1968, but the government declined in 1971. A private trust took over that July and opened her to visitors in October 1971; she joined the Imperial War Museum in 1978. City of London Sea Cadets have met aboard since 1973, and 204,656 people toured her in 2025.
