HMS Belfast

HMS Belfast is a Town-class of the Royal Navy, originally commissioned in 1939 and renowned for her service in the Second World War and the , before being preserved as a on the River Thames in since 1971. Built by Harland and Wolff in , , she was one of the most powerful cruisers of her era, equipped with twelve 6-inch guns and advanced systems, and played pivotal roles in convoy protection, the sinking of the German battleship Scharnhorst, and the D-Day landings. Today, as a branch of the Imperial War Museums, she attracts visitors to explore her decks, crew quarters, and wartime artifacts, serving as a tangible link to naval history. Laid down on 30 December 1936 and launched on 17 March 1938 by , wife of , Belfast was completed and commissioned on 5 August 1939, just weeks before the outbreak of the Second World War. Assigned to the at , she quickly saw action in the , intercepting the German liner Cap Norte in October 1939, but suffered severe damage on 21 November when she struck a German magnetic mine off the , requiring over three years of repairs and modernization in the United States and . This refit enhanced her armament and fire-control systems, making her one of the Royal Navy's most capable cruisers upon rejoining the fleet in November 1942. During the Second World War, Belfast escorted Arctic convoys to the , enduring harsh conditions while battling U-boats and aircraft, including operations for convoys JW 53 and RA 53 in 1943. Her most notable engagement came on 26 December 1943 at the Battle of North Cape, where she detected and shadowed the battleship Scharnhorst, contributing to its destruction by HMS and other Allied forces in the . In 1944, she supported the Normandy invasion on 6 June as part of the bombardment fleet for , firing over 4,000 shells and later targeting German positions at on 28 June. After the war, Belfast participated in the reoccupation of in 1945, served in the from 1950 to 1952 where she conducted shore bombardments supporting forces, including a notable first-salvo hit on a target in March 1951, and underwent further modernization between 1955 and 1959. Decommissioned in 1963 and placed in reserve, she faced scrapping but was saved through public campaigns and acquired by the Imperial War Museums, opening to the public on 21 October 1971 as the first major warship preserved for the nation since HMS Victory. Permanently moored between and Tower Bridges, she now houses interactive exhibits on her crew's life and naval operations, drawing over 215,000 visitors annually as of 2023.

Design and construction

Specifications and features

HMS Belfast belonged to the Town-class of light cruisers, specifically the subgroup, which incorporated design refinements for enhanced stability and armament layout compared to the earlier and subgroups. Her standard displacement measured 10,000 tons, increasing to 14,900 tons at full load, reflecting the class's emphasis on balancing firepower with treaty-limited tonnage. These figures positioned her as a versatile capable of extended operations in varied theaters. The ship's dimensions included an overall length of 613 feet 6 inches (187 ), a beam of 63 feet 4 inches (19.3 ), and a draught of 17 feet 3 inches (5.3 ) forward, with the at approximately 554 feet 6 inches to optimize hydrodynamic efficiency. This configuration, combined with a transom unique to the Edinburgh subgroup, improved in rough seas, a critical feature for North Atlantic duties. The hull design prioritized structural integrity, with watertight compartments and double bottoms to mitigate threats. Armor protection focused on vital areas: a main belt of 4.5 inches (114 mm) shielded the machinery and magazines, while deck armor ranged from 2 inches (51 mm) over the engine spaces to 3 inches (76 mm) above ammunition storage. faces received up to 4.5 inches (114 mm) of armor, tapering to 1.5 inches (38 mm) on sides and roofs, with 2.5-inch (64 mm) bulkheads sealing off key sections. These measures, drawn from lessons of interwar naval exercises, provided adequate defense against cruiser-caliber gunfire without exceeding displacement constraints. Internally, Belfast was equipped to sustain a crew of around 850 personnel, including officers and ratings, with thoughtful accommodations to maintain operational effectiveness during prolonged deployments. Facilities included a dedicated for religious services, an onboard producing fresh daily, a dental for medical care, and a space for recreational films to boost morale. These amenities, integrated into the mess decks and lower levels, underscored the Royal Navy's recognition of crew welfare as essential to combat readiness. Propulsion relied on four Parsons single-reduction geared steam turbines, powered by four three-drum oil-fired boilers, delivering 80,000 shaft horsepower to four shafts. This setup enabled a maximum speed of 32 knots, sufficient for escort and fleet screening roles. Fuel efficiency allowed a range of 8,664 nautical miles at 13 knots, supporting extended patrols. As completed in 1939, Belfast's suite featured the Type 79Y early-warning system for air detection, mounted on the mainmast, marking an advancement in naval electronics for the era. Communication systems included high-frequency sets for secure voice and transmissions, integrated with for coordination in formation. These technologies, though rudimentary by later wartime standards, provided Belfast with superior from commissioning. Key differences from other Town-class cruisers lay in the Edinburgh subgroup's modifications, such as repositioned secondary armament mounts amidships for wider firing arcs and a broadened beam for better stability under heavy weather conditions. These alterations, implemented during Belfast's construction, addressed vulnerabilities observed in earlier sisters like HMS Southampton. She was also equipped with a catapult and hangar for two Supermarine Walrus seaplanes for reconnaissance.

Armament and propulsion

HMS Belfast's primary armament consisted of twelve BL 6-inch Mark XXIII guns arranged in four triple s designated 'A', 'B', 'X', and 'Y', positioned two forward and two aft. These guns fired 112-pound shells using 30-pound charges, achieving a maximum range of approximately 14 miles and a of up to eight rounds per minute per gun with a trained . Each required 27 members for operation, with an additional 22 handling ammunition in the shell rooms and magazines across multiple decks. The secondary battery included eight QF 4-inch Mark XVI dual-purpose guns mounted in four twin turrets, designed for both surface and anti-aircraft roles. Close-range anti-aircraft defense was provided by sixteen 2-pounder (40 mm) "pom-pom" guns in two octuple mounts, supplemented by eight 0.5-inch (12.7 mm) machine guns. For , the ship carried two quadruple 21-inch torpedo tubes with eight es and provisions for depth charges, though the latter were primarily handled by escorts in operations. Fire control systems integrated director control towers for the main and secondary armaments, enhanced by radar from commissioning. The primary gunnery radar was the Type 284 set, mounted on the director, which provided range and bearing data to the for accurate targeting. This setup allowed coordinated fire from all turrets, with the system processing inputs from optical rangefinders and radar to compute firing solutions. Propulsion was driven by four Parsons single-reduction geared steam turbines delivering 80,000 shaft horsepower, powered by four Admiralty three-drum oil-fired boilers. The ship carried 2,400 tons of , enabling a top speed of 32 knots on trials and an endurance of approximately 8,000 nautical miles at 16.5 knots. This combination of power and efficiency supported Belfast's role in extended fleet operations and escorts.

Building and commissioning

HMS Belfast, a Town-class , was constructed by Harland and Wolff at their shipyard in Belfast, . Her was laid down on 10 December 1936 as Job Number 1000, marking the beginning of a build process that reflected the Royal Navy's pre-war expansion efforts. The ship was launched on 17 March 1938——by , wife of Prime Minister , in a that highlighted the vessel's to British naval strength. The construction cost approximately £2.14 million, according to 1938 naval estimates, encompassing armament such as £75,000 for the six-inch guns and £66,500 for the facilities. Following launch, Belfast underwent , a phase that incorporated design refinements typical of the evolving Town-class specifications amid rising international tensions. This period extended from March to August 1939, during which the ship was prepared for service, though pre-war pressures on resources contributed to a measured pace in completing internal systems and equipment installation. Sea trials commenced in early 1939, where Belfast demonstrated her designed capabilities, attaining speeds exceeding 32 knots during high-speed runs, confirming the effectiveness of her propulsion system comprising four Parsons geared steam turbines and four Admiralty 3-drum boilers. These trials served as initial shakedown operations, allowing the engineering and deck crews to familiarize themselves with the vessel's handling. On 5 August 1939, just weeks before the outbreak of World War II, HMS Belfast was formally commissioned into the Royal Navy under the command of Captain G. A. Scott, DSO, RN, with a complement of 761 officers and ratings. Post-commissioning, the crew underwent further training exercises and short operational cruises to hone proficiency in gunnery, navigation, and damage control before transitioning to full wartime readiness.

World War II service

Commissioning and early operations: 1939–1942

HMS Belfast was commissioned into the on 5 August 1939 under the command of Captain G. A. Scott, DSO, , just weeks before the outbreak of the . Assigned to the 18th Cruiser Squadron at , she immediately joined the Northern Patrol, operating between and the Islands to enforce the against by inspecting neutral shipping for and potential enemy vessels. During these early patrols in September and October 1939, Belfast reached speeds exceeding 32 knots while searching merchant ships, contributing to Britain's efforts to isolate German trade routes in the North Atlantic. On 9 October 1939, approximately 50 miles northwest of the , Belfast intercepted the 13,615-ton German liner SS Cap Norte, which was disguised as the neutral Swedish vessel SS Ancona and attempting to slip back to Germany from with over 400 German reservists aboard. The boarding party from Belfast confirmed the deception, seized the ship as a prize, and escorted her to in the Orkneys, where she was repurposed as the troopship Empire Trooper; this capture marked the largest enemy merchant vessel taken by the Royal Navy in the war's early months and denied valuable manpower. The operation highlighted Belfast's role in disrupting logistics, though no specific beyond the reservists was publicly detailed from the . Tragedy struck on 21 November , when , departing for gunnery exercises, detonated a magnetic mine laid by U-21 in the near May Island at 10:58 a.m. The explosion caused severe structural damage, breaking the ship's , distorting the , and flooding forward compartments, while disabling the engines and injuring 21 crew members, one fatally. Despite the crew's efforts to control the flooding and prevent sinking, initial assessments at revealed extensive "whipping" of the structure, rendering the inoperable and sidelining her original design vulnerabilities to underwater threats. Following temporary stabilization at , Belfast was towed to Devonport Dockyard in 1939 for comprehensive repairs and modernization, a process that lasted until her recommissioning in November 1942. The work involved rebuilding the forward hull section, straightening the , overhauling the machinery—including stripping and reassembling the engines and boilers—and incorporating wartime upgrades such as enhanced anti-aircraft armament and systems. Captain Scott was relieved during this extended downtime, with subsequent command changes reflecting the ship's inactive status until Captain F. R. Parham took over for her return to service. The prolonged refit underscored the Royal Navy's commitment to restoring the nearly new vessel rather than scrapping her.

Arctic convoys and Battle of North Cape: 1942–1943

Following her extensive repairs after the mine incident in 1939, HMS Belfast underwent significant upgrades, including enhanced systems such as the Type 273 surface warning radar and Type 282 gunnery control radars, which greatly improved her detection and fire control capabilities in low-visibility conditions. She was recommissioned on 3 at Devonport under the command of Captain Frederick R. Parham, , with Rear-Admiral F. H. G. Dalrymple-Hamilton, , , flying his flag as commander of the 10th Squadron. Belfast quickly joined the at and was deployed to protect Arctic convoys ferrying vital supplies, including tanks, aircraft, and fuel, from Britain to the Soviet ports of and . From late 1942, she escorted several high-risk convoys through the treacherous , facing severe challenges from Arctic storms, dense fog, and perpetual darkness during winter months, where temperatures often fell below -30°C (-22°F) and heavy icing threatened ship stability. Specific duties included providing close escort and anti-submarine screening for convoy JW 51A, which departed on 15 December 1942 with 16 merchant ships, successfully delivering all cargo despite U-boat sightings and reconnaissance. She then supported JW 51B, sailing on 22 December 1942 with 14 merchant vessels, where German surface forces attempted an interception leading to the on 31 December, though Belfast's role was in the distant covering force that deterred further enemy commitment. In early January 1943, Belfast escorted the return convoy RA 52 from the , navigating through gale-force winds and evading submarine threats to ensure the safe return of empty transports. These operations highlighted the convoy system's importance, with Belfast's proving essential for early warning against prowling s and surface raiders, contributing to the delivery of over 4 million tons of aid to the Eastern Front by war's end. Belfast's most notable action came during the protection of convoy JW 55B in December 1943, when she formed part of Vice-Admiral Robert Burnett's Force 1, comprising cruisers , , and , tasked with screening the convoy against German intervention. On 26 December, at approximately 08:40, Belfast's Type 273 detected the Scharnhorst at a of about 30 miles (48 km) to the east, allowing the British force to maneuver for interception despite poor visibility. Under Captain Parham's command, Belfast shadowed the larger German warship at high speed, engaging her with 6-inch gunfire in two brief exchanges at 09:24 and 12:25, scoring hits that damaged Scharnhorst's radar and forward turrets while sustaining only minor damage from return fire. As night fell, Belfast maintained radar contact and, at 16:47, illuminated the retreating Scharnhorst with star shells, revealing her position to the approaching HMS and her escorts. This critical illumination enabled Duke of York to commence accurate gunnery at 16:48, inflicting devastating damage; Belfast then closed to but held fire as Scharnhorst capsized and sank at 19:45 following a barrage of torpedoes and shells from the British force, with only 36 of her 1,968 crew surviving. Belfast emerged with negligible structural harm and no fatalities among her crew, though the engagement underscored her radar-directed gunnery's effectiveness. For their gallantry, several crew members, including Leading Stoker Larry Fursland for maintaining engineering functions under fire, received mentions in despatches, while Parham was awarded the .

Support for D-Day and attacks on Tirpitz: 1944

In early 1944, Belfast participated in carrier operations against the , stationed in Kaafjord, , and posing a threat to Allied shipping. On 3 April, as part of , she screened aircraft carriers Victorious and Furious, providing anti-aircraft cover with her enhanced AA batteries and radar spotting to direct 21 bombers in a dive-bombing that damaged 's superstructure and rendered her temporarily unseaworthy. Belfast repeated this role in Operation Mascot on 17 July, escorting strikes from carriers Indomitable and Furious amid poor weather, though the raid achieved only near-misses due to effective German smokescreens. In late August, during —a series of four coordinated raids—she again offered AA protection and spotting support for aircraft from Formidable, Furious, and Indomitable, inflicting further damage on 's armament and deck, though the battleship survived until later RAF bombing. These actions neutralized as a major threat without direct surface engagement. Later in April 1944, Belfast was transferred from Arctic convoy duties to the Home Fleet at to prepare for , the Allied invasion of . Assigned as flagship of Bombardment Force E under F. H. G. Dalrymple-Hamilton, she sailed from on 5 June and positioned off the coast amid a massive naval armada. On 6 June, at 5:30 a.m., Belfast opened fire with her 6-inch guns on coastal defenses, including positions at La Riviere and Longues-sur-Mer, supporting the British and Canadian assaults on and beaches during Operation Neptune. Her radar-directed salvos, enhanced by equipment refined during prior Arctic service, helped suppress enemy fire, enabling the safe landing of over 24,000 troops in her sector by day's end. Following the initial landings, Belfast remained on station off for five weeks, contributing to the consolidation of the beachhead as part of the ongoing naval support for Operation Neptune, which extended until 24 July. She provided protective fire for the construction and defense of the Mulberry B artificial harbor at Arromanches, firing at German counter-battery positions and troop concentrations to safeguard supply lines that delivered over 400,000 tons of materiel by mid-July. In total, Belfast expended more than 4,000 6-inch shells during the campaign, targeting fortified positions and supporting advances inland, while enduring near-misses from enemy shore artillery. Later in July, she escorted minelaying operations in the to restrict German naval movements and patrolled against incursions, while contributing to efforts to intercept V-1 flying bombs launched from northern toward .

Operations in the Far East: 1945

Following a refit at Smiths Dock on the Tyne that began in April 1945 to equip her for tropical operations, including enhancements to her , anti-aircraft armament, and ventilation systems, HMS Belfast departed British waters in June 1945 for redeployment to the . She sailed via the South Atlantic, rounding the , and transited the , a journey marked by the logistical challenges of long-haul steaming in increasingly warm climates that tested the crew's endurance and the ship's cooling systems. The cruiser arrived in Sydney, Australia, in early August 1945, where she joined the (BPF) as part of the 2nd Cruiser Squadron, assuming the role of flagship under Captain Frederick Parham. With Japan's announcement of surrender on 15 August 1945—just days after Belfast's arrival—the ship did not engage in planned combat operations against forces, such as those supporting the invasion of . Instead, Belfast contributed to immediate post-war efforts, providing humanitarian aid to Allied prisoners of war liberated from camps across the region and supporting the reoccupation of British territories. In , as of the , she anchored in the Whangpoo at , hosting events for children of Allied internees and facilitating the of British nationals. The crew also participated in formalities surrounding the acceptance of surrenders in the , underscoring the transition from wartime vigilance to duties. Service in the BPF during this period exposed Belfast to the rigors of tropical conditions, including high humidity that strained and required constant to prevent , as well as ongoing fuel conservation measures inherited from the fleet's earlier shortages, though these eased with the war's end. By late 1945, with her combat role curtailed, Belfast remained deployed in the region, preparing for extended peacetime operations amid the logistical demands of and regional stability.

Postwar operations

Atlantic and Mediterranean duties: 1945–1950

Following the Japanese surrender in August 1945, HMS Belfast, serving as flagship of the 2nd Cruiser Squadron in the , continued occupation and peacekeeping duties in the until the autumn of 1947, when she returned to the . Upon arrival at in October 1947, she was paid off into reserve and underwent a refit in 1948 to prepare for further service. Belfast remained in reserve at until recommissioned on 22 September 1948 under Captain E. K. Le Mesurier. She then made a ceremonial visit to , , on 21 October 1948, to receive a silver bell from the city, marking her ties to her namesake port. Shortly thereafter, on 23 October 1948, she departed for the , arriving in in December as flagship of the 5th Cruiser Squadron, relieving and continuing regional duties until redeployment for the in 1950.

Korean War service: 1950–1952

In July 1950, shortly after the outbreak of the on 25 June when forces invaded , HMS Belfast, under the command of Captain Aubrey Sinclair Ford, departed , , for operations off the Korean coast as part of the naval forces. She joined the UN Blockading and Escort Force, designated Task Force 95, to enforce a naval against and provide gunfire support to UN ground troops. During her initial deployment, Belfast conducted pre-landing bombardments in support of the UN amphibious assault at Inchon on 15 September 1950, firing on coastal defenses to aid the surprise landing that reversed advances and recaptured . Her six-inch guns targeted enemy positions, contributing to the operation's success amid challenging tidal conditions at the port. Throughout 1950 and into 1951, Belfast engaged in extensive shore bombardments along the North Korean coastline, including operations during the siege of in October 1951, where she shelled harbor defenses and supply routes to disrupt communist reinforcements. Over the course of her service, the fired more than 8,000 six-inch shells at North Korean , troop concentrations, and , wearing out her gun barrels which required replacement during a refit in . These actions supported UN advances and inflicted significant damage on enemy logistics, though Belfast also faced counterfire from shore batteries that occasionally damaged the ship. Belfast's blockade duties focused on patrolling the east coast of , interdicting mining threats and smuggling, while escorting UN convoys and countering North Korean naval activity. She spent over 400 days on active , steaming more than 80,000 miles in harsh conditions reminiscent of her service, providing illumination and support to ground forces and island garrisons. In August 1951, after a brief refit, Belfast relieved HMS Ceylon to begin her second tour, continuing bombardments until she was herself relieved by HMS Birmingham and HMS Newcastle in September 1952, marking the end of her Korean War service.

Modernization and final active service

Reconstruction: 1955–1959

Following her return from service in 1952, HMS Belfast was decommissioned and placed in reserve at Devonport. In March 1955, the approved a major modernisation programme to adapt the ageing Town-class cruiser for continued service amid evolving naval requirements, including enhanced anti-submarine and anti-aircraft capabilities. The extensive refit commenced at HM Dockyard Devonport on 6 January 1956 and lasted until May 1959, far exceeding initial expectations due to ongoing design debates over integrating modern systems into the pre-war hull and congestion at the overcrowded yard, which prioritised other urgent repairs. The total cost reached £5.5 million, a significant investment reflecting the ship's proven reliability and the Royal Navy's need for versatile escorts in an era of missile and helicopter integration. Structurally, the refit transformed Belfast's silhouette with a completely rebuilt, fully enclosed for improved command and visibility, new lattice masts to support advanced electronics, and an ASDIC dome added beneath the hull to enhance detection, addressing vulnerabilities exposed by postwar threats. Armament updates preserved the proven triple 6-inch for surface gunnery but removed the obsolete tubes to free space for . New close-range defences included a STAAG twin 40 mm mount for stabilised anti-aircraft fire, while the was installed forward to launch depth charges against submerged targets, marking Belfast's shift toward multifaceted escort duties. Electronically, the ship received a comprehensive upgrade with Type 277Q surface-search and height-finding , Type 293 target indication, and Type 968 early warning sets mounted on the new foremast, replacing outdated wartime equipment for better detection in cluttered environments. Fire control systems were modernised with improved directors linked to the retained guns, enhancing accuracy against air and surface threats. efficiency was boosted by retubing the boilers and Yarrow water-tube machinery, allowing sustained speeds of up to 32 knots without major redesign. These modifications, though not as radical as full conversions for newer classes like the Tigers, effectively bridged Belfast to the missile age, enabling her recommissioning on 12 May for another four years of .

Final deployments: 1959–1963

Following her extensive , HMS Belfast recommissioned at Devonport on 12 May , equipped with updated anti-aircraft batteries, new masts, an enclosed bridge, and protective measures against nuclear, biological, and chemical threats. She rejoined the for routine operations and exercises in European waters. In late 1959, Belfast deployed to the Station, arriving in on 16 December to support British interests in the region amid tensions. Throughout 1960, the conducted intensive naval exercises, demonstrating her modernized and gunnery systems while making goodwill visits to ports including , , , and Ceylon (now ). These activities underscored her role in maintaining maritime security and alliance commitments in . Belfast remained on the Far East Station into 1962 under Captain Morgan Morgan-Giles, her final commanding officer during active service, participating in joint maneuvers with Commonwealth and allied navies. In June 1962, she transferred to the , contributing to readiness operations in a period of heightened global alertness. Returning to the in July 1963, Belfast paid off into reserve at , her crew significantly reduced from over 700 to reflect the ship's growing obsolescence against emerging missile threats and jet aircraft. Prior to full decommissioning, she briefly recommissioned that year to serve as flagship for the and support training, including a two-week cadet cruise to for Sea Cadets to provide hands-on experience.

Decommissioning and preservation efforts

Reserve status and initial preservation: 1963–1971

Following her final active deployment in 1963, HMS Belfast was decommissioned at Devonport Dockyard. She was subsequently placed in reserve and towed to Creek near , where she served as an accommodation ship for the local reserve division. This role involved providing berthing for personnel, but the prolonged inactivity began to cause significant deterioration to her hull and machinery, exacerbating maintenance challenges in the humid creek environment. By , the ship's condition had worsened to the point that the announced plans to dispose of her, with scrapping appearing likely as part of broader fleet reductions. The threat prompted initial concerns among naval veterans and historians, who recognized Belfast's from her and service. Preservation discussions gained momentum in 1967 when staff from the visited Portsmouth to assess options for conserving a representative Second World War cruiser, initially considering the nearby HMS Gambia before shifting focus to Belfast. The preservation campaign intensified in 1967–1968 through coordinated efforts by senior naval officers, including Rear-Admiral Sir Morgan Morgan-Giles, and public supporters who highlighted the ship's role in key battles like the Battle of North Cape. A public fundraising appeal was launched to cover the costs of acquisition and relocation, emphasizing her value as a tangible link to Britain's naval heritage. These initiatives created widespread media attention and pressure on the government, temporarily halting immediate scrapping plans. In October 1971, following the success of the early advocacy, HMS Belfast received a reprieve and was towed from Creek to the River Thames in , where she was moored in the near as a prospective . This move marked the end of her reserve status and the beginning of her transition to public preservation, with initial surveys confirming the feasibility of long-term mooring despite ongoing structural concerns.

HMS Belfast Trust era: 1971–1978

The HMS Belfast Trust was established in 1971 under the chairmanship of Rear-Admiral Sir Morgan Morgan-Giles, a former captain of the ship, following the government's decision against preservation. The trust, supported by contributions from the Maritime Trust founded by HRH the in 1969, launched a successful campaign to acquire and maintain the vessel as a floating dedicated to her naval history. In July 1971, ownership was formally transferred from the to the trust, averting her scrapping. HMS Belfast was then towed from Fareham Creek near to the , arriving at her permanent mooring on the River Thames adjacent to on 15 October 1971, where a specially dredged berth had been prepared. She opened to the public just six days later on , 21 October 1971, initially featuring basic exhibits on her service, including Arctic convoy operations and the Battle of North Cape. Under the trust's stewardship, operations relied entirely on self-generated revenue from ticket sales, proceeds, and donations, with guided tours emphasizing the ship's decks, gun turrets, and engine rooms. Maintenance proved challenging, as the aging suffered from and occasional leaks due to tidal exposure and structural wear, requiring constant volunteer and limited professional efforts to keep her seaworthy. By December 1975, the attraction had drawn 1.5 million visitors, earning the trust the British Tourist Authority's "Come to Britain" trophy in 1972 for its role in promoting naval heritage. Financial pressures mounted through the mid-1970s, as rising costs for repairs, , and outpaced income despite strong attendance. By 1977, the trust's position had become marginal, prompting negotiations to transfer management to a larger institution capable of ensuring long-term preservation.

As a museum ship

Transfer to : 1978–2000

In 1978, following financial challenges faced by the HMS Belfast Trust, the organization merged with the (IWM), transferring ownership of the ship to the national institution on 1 March for a nominal sum, making HMS Belfast the IWM's third branch after its headquarters and airfield. This handover integrated the vessel into the IWM's professional curatorial framework, providing dedicated staffing, conservation expertise, and resources to ensure its long-term preservation as the largest object in the museum's collection. The transition marked a shift from private charitable efforts to state-supported operations, enabling expanded public access and interpretive development while maintaining the ship's mooring in the . Under IWM management, initial exhibits emphasized HMS Belfast's wartime service, with restorations highlighting key operational spaces such as the forward gun turrets—capable of firing the ship's 6-inch guns—and the engine rooms, where visitors could explore the machinery that powered the during . These displays focused on narratives of the Battle of North Cape, D-Day landings, and Arctic convoys, using artifacts, photographs, and crew testimonies to convey the human and technical aspects of . The ship's nine decks were progressively adapted for self-guided exploration, fostering an immersive experience that complemented the IWM's broader mission to document modern conflict. Visitor numbers grew steadily, reaching over 250,000 annually by the , establishing HMS Belfast as one of London's leading tourist attractions and drawing audiences interested in . Educational programs were introduced for groups, including guided tours and workshops on naval life and wartime technology, which engaged thousands of students each year and supported curriculum topics in and . Maintenance efforts during this period included periodic dry-dockings to address corrosion and wear from Thames exposure; in 1982, the ship was towed to Docks in for abrasive blasting, hull repainting, and structural inspections, ensuring its structural integrity without major alterations. A similar refit occurred in 1999 at , involving further conservation of the hull and superstructure to sustain the vessel's seaworthy appearance. These interventions, funded through IWM budgets, prevented deterioration and allowed the ship to remain a vibrant museum through the end of the century.

Preservation challenges and incidents: 2000–present

On 29 November 2011, the gangway providing access to collapsed into the River Thames, injuring two contractors with minor injuries and necessitating the evacuation of approximately 170 visitors. The incident led to an immediate closure of the ship for safety assessments and structural repairs, with the (IWM) overseeing the investigation and subsequent enhancements to the access infrastructure. reopened to the public in April 2012 following these repairs, which included reinforcements to prevent future failures. Preserving HMS Belfast presents ongoing challenges due to its permanent mooring on the River Thames, where fluctuating and exposure to corrosive elements accelerate degradation and erosion. To combat this, IWM installed an advanced impressed current (ICCP) system in 2019–2020, featuring titanium anodes that automatically adjust to tidal changes in water chemistry, ensuring for the next 25 years. This upgrade built on earlier IWM maintenance efforts and addressed the ship's vulnerability to electrochemical in the estuarine environment. The forced HMS Belfast to close to visitors from March 2020 until July 2021, an extended shutdown that allowed IWM to undertake comprehensive work, including anti-corrosion treatments, deck repairs, repainting, and structural inspections. During this period, IWM developed virtual tours using 360-degree panoramas and interactive deck plans to maintain public engagement, enabling remote exploration of inaccessible areas like engine rooms. The 15-month refit enhanced the ship's overall condition, with IWM's conservation teams focusing on long-term preservation strategies outlined in their 2020–2025 research plan. Since reopening, IWM has continued proactive measures against Thames-related threats, such as periodic ultrasonic hull surveys and dehumidification systems to mitigate internal deterioration, ensuring the remains viable as a into the 2020s. No major incidents have been reported post-2021, reflecting the effectiveness of these integrated preservation efforts.

Exhibitions, interpretation, and legacy

HMS Belfast features nine decks open to visitors, allowing exploration of the ship's interior from the engine rooms to the bridge, with interactive recreations of and environments, including the operations room equipped with original and tools, and crew quarters depicting daily life aboard. These displays emphasize the ship's role in key conflicts, such as the Arctic convoys and D-Day bombardment, through restored artifacts and simulated command centers. Interactive audio guides, available in multiple languages and included in admission, provide narrated insights into the ship's history and operations, enhancing self-guided tours across the decks. The museum's interpretation centers on the personal stories of the approximately 950 personnel who served aboard, highlighting their experiences in mess decks, the onboard , radio station, and bakery, to convey the human element of naval service. This approach fosters discussions on the ethical dimensions of , including the psychological and social impacts on crews during prolonged deployments in harsh conditions like the and Korean waters.
