HMS Belfast

The Town class began in 1933 as the Admiralty's reply to the Imperial Japanese Navy's Mogami-class cruiser: 11,200 tons, fifteen 6-inch guns, over 35 knots. What the Admiralty wanted was a 9,000-ton ship armoured against a direct hit from an 8-inch shell, good for 32 knots and mounting twelve 6-inch guns. By 1935 it wanted more firepower still. Five triple turrets were judged impractical and no workable quadruple turret could be developed, so in May 1936 the Admiralty settled on triple turrets of improved design, whose weight saving bought extra deck armour. That became the 10,000-ton Edinburgh subclass.

Belfast was ordered from Harland and Wolff on 21 September 1936, her keel laid that December, at an expected cost of £2,141,514 — £75,000 of it guns, £66,500 the pair of Supermarine Walrus amphibians. She was the first ship in the Royal Navy named after the capital of Northern Ireland, and she went down the ways on Saint Patrick's Day, 17 March 1938, launched by Anne Chamberlain, wife of the Prime Minister, with Pathé News filming.

Completed, she ran 613 feet 6 inches overall and displaced 10,420 long tons on trials. Four three-drum oil-fired Admiralty water-tube boilers turned Parsons geared turbines on four shafts for 32.5 knots and a range of 8,664 nautical miles at 13 knots. Her twelve Mk XXIII 6-inch guns sat in four triple turrets directed by an Admiralty Fire Control Table — a mechanical computer — and could throw up to 96 rounds a minute between them. Twelve 4-inch guns in twin mounts, two eight-barrel pom-poms and six 21-inch torpedo tubes completed her, behind a 4.5-inch belt.

Commissioned on 5 August 1939 under Captain G. A. Scott with a crew of 761, she joined the 18th Cruiser Squadron at Scapa Flow, part of the blockade of Germany. At 11:40 on 3 September she received the signal "Commence hostilities at once against Germany". October found her on the northern patrol, stopping and boarding neutral traffic: the Norwegian Tai Yin and the Swede Uddeholm both went into Kirkwall under prize crews. On 9 October she intercepted the 13,615-ton German liner Cap Norte north-west of the Faroes, disguised as the Swedish Ancona and running home from Brazil with German reservists aboard, and her crew later drew prize money.

She was anchored at Scapa Flow on the night of 13–14 October when U-47 got into the anchorage and torpedoed the battleship Royal Oak, and left for Loch Ewe the following morning. Reassigned to a striking force at Rosyth, she was leaving the Firth of Forth for a gunnery exercise at 10:58 on 21 November 1939 when she detonated a magnetic mine. The blast broke her keel, wrecked an engine and boiler room, and hogged the keel three inches upward. Forty-six men were injured; Painter 2nd Class Henry Stanton, thrown against the deckhead, later died of a head injury.

The hull damage was more insidious than dramatic — a small hole below a boiler room, but shock damage that warped structure, broke machinery and deformed decks throughout. She was reduced to care and maintenance in January 1940 and her crew dispersed. Over more than two years her hull was straightened, rebuilt and strengthened, her belt extended and thickened, and a bulge worked in amidships to carry the new topweight, taking her beam out to 69 feet. She came back with eighteen 20 mm Oerlikons and a full radar suite: Type 284 and 283 for the main battery, 285 for the secondaries, 273 for surface warning, 281 and 242 for air warning.

Recommissioned at Devonport on 3 November 1942 under Captain Frederick Parham, she rejoined the Home Fleet as flagship of the 10th Cruiser Squadron, flying the flag of Rear-Admiral Robert Burnett. The squadron's work was escorting the Arctic convoys to the Soviet Union out of Scapa Flow and Iceland — hazardous, unglamorous and constant. Her radar had made her aircraft largely redundant and the Walruses went ashore in June 1943. That October she covered Operation Leader, an airstrike on German shipping off Bodø flown from the American carrier Ranger.

On 26 December 1943 she fought the Battle of North Cape, in the darkness of the Arctic winter. Bruce Fraser, Commander-in-Chief Home Fleet, had hoped the German battleship Scharnhorst would come out against convoy JW 55B, and she did, sailing on Christmas Day. Force One — Norfolk with her 8-inch guns, Sheffield and Belfast, with three destroyers — met her first, kept her off the convoy and drove her back damaged. Force Two, the battleship Duke of York with the cruiser Jamaica and four destroyers, waited to the south.

When Scharnhorst came in again at noon, the two forces caught and sank her. Belfast's part was the hardest to see and the most valuable: as squadron flagship she was among the first to make contact and coordinated the defence of the convoy, and after Scharnhorst turned away Burnett shadowed her by radar from beyond visual range, holding the contact that let Duke of York intercept.

She refuelled at Kola Inlet and was back at Scapa on New Year's Day 1944. In March she sailed with the covering force for Operation Tungsten, the Fleet Air Arm strike on Tirpitz in Altafjord; forty-two Barracudas from Victorious and Furious, with eighty fighters, scored fourteen hits on 3 April and put the German battleship out of action for two months for the loss of one aircraft. On 8 May Belfast carried the King on his pre-invasion visit to the Home Fleet.

For Normandy she was headquarters ship of Bombardment Force E, flying the flag of Rear-Admiral Frederick Dalrymple-Hamilton, supporting British and Canadian landings in the Gold and Juno sectors. Churchill announced on 2 June that he intended to watch the invasion from her deck. Eisenhower and the First Sea Lord, Sir Andrew Cunningham, opposed it; in the end an intervention by the King stopped him going.

At 5:30 a.m. on 6 June she opened fire on the German battery at Ver-sur-Mer and kept it suppressed until the 7th Battalion, Green Howards, overran the position. She supported Canadian troops moving inland from Juno on 12 June, was threatened at anchor by E-boats on the night of 6 July and slipped away behind a smoke screen, and fired her last round in European waters on 8 July alongside the monitor Roberts and the battleship Rodney during Operation Charnwood. In five weeks off Normandy she had fired 1,996 rounds from her 6-inch guns.

Refitted for the tropics and for kamikaze defence, she reached Sydney on 7 August 1945 as flagship of the 2nd Cruiser Squadron of the British Pacific Fleet, days before the Japanese surrender. She stayed in the Far East, visited her home city in October 1948 to a Trafalgar Day march and the gift of a silver ship's bell, and was the Far East Station's headquarters ship during the Amethyst incident on the Yangtze in April 1949. She was at Hakodate on 25 June 1950 when North Korean forces crossed the 38th Parallel.

Through 1950–52 she patrolled and bombarded the Korean coast from Sasebo. Supporting the fighting around Yongdok on 19 July 1950 she put down an accurate 350-round shoot and was called a "straight-shooting ship" by an American admiral. On 29 July 1952, engaging a battery on Wolsa-ri island, a 75 mm shell struck a forward compartment and killed a British sailor of Chinese origin in his hammock, wounding four other Chinese ratings — the only time she was hit in the whole war. She had steamed over 80,000 miles in the combat zone and fired more than 8,000 six-inch rounds.

An extended refit from 1956 to 1959 cost £5.5 million, enclosing her bridge into a two-tiered five-sided structure against nuclear, biological or chemical attack and altering her silhouette for good. Final commissions took her round the Far East and to Tanganyika's independence ceremony in 1961 before she paid into reserve. Preservation was rejected by the government in 1971, and a private trust chaired by Rear-Admiral Sir Morgan Morgan-Giles, her own former captain, fought the decision in Parliament and won.

Handed over that July, she was towed to a dredged berth above Tower Bridge and opened to the public on Trafalgar Day, 21 October 1971 — the first naval vessel saved for the nation since Victory. She became the Imperial War Museum's third branch in 1978, sits on the National Historic Fleet, and still flies the White Ensign by special dispensation. She has hosted the City of London Sea Cadets since 1973, and took 204,656 visitors in 2025.
