Type 26 frigate
The Type 26 frigate, designated as the City class by the Royal Navy, is a family of eight advanced multi-role warships under construction to replace the ageing Type 23 frigates, with primary emphasis on anti-submarine warfare while supporting air defence, surface strike, and humanitarian operations.[1] Designed by BAE Systems as the Global Combat Ship, these vessels incorporate a low-acoustic-signature hull, integrated electric propulsion for quiet operation, and modular mission bays for flexibility in deploying unmanned systems or special forces.[2] Each ship accommodates a crew of up to 208 personnel and features enhanced surveillance via the Artisan 3D radar capable of tracking over 800 targets.[1] The lead vessel, HMS Glasgow, began construction in 2017, with the first three ships slated for service before 2030, marking a significant upgrade in the Royal Navy's surface fleet capabilities.[1] The programme's export-oriented design has secured international adoption, forming the basis for Australia's six Hunter-class frigates, optimized for anti-submarine and surface warfare roles with entry into service in the early 2030s, and Canada's fifteen River-class destroyers, which emphasize similar multi-domain operations.[3] In September 2025, Norway committed to acquiring at least five Type 26 variants, expanding the collaborative framework among allied navies.[4] Construction progresses at BAE Systems' facilities on the River Clyde, where recent milestones include the installation of the class's first 127mm main gun on HMS Glasgow and the steel-cutting for HMS Sheffield, underscoring the platform's role in sustaining UK shipbuilding and defence exports.[5][6]Development History
Origins and Initial Requirements
The Type 26 frigate program originated from the Future Surface Combatant (FSC) initiative, launched by the UK Ministry of Defence in 1998 to procure successors for the Royal Navy's Type 22 Batch 3 and Type 23 Duke-class frigates. These vessels were approaching the end of their planned service lives, with Type 22s retiring by the early 2010s and Type 23s requiring replacement from the mid-2020s to sustain the fleet's operational tempo.[7][8][9] Initial requirements under the FSC emphasized a single, adaptable class of warships capable of multi-role operations, including primary anti-submarine warfare (ASW) to counter sophisticated diesel-electric and nuclear submarines, secondary anti-air and surface warfare, and support for expeditionary tasks. The design was intended to incorporate modular mission bays for rapid reconfiguration, advanced sensors for threat detection, and vertical launch systems for missiles, reflecting the need to address post-Cold War uncertainties while prioritizing cost-effective hull commonality for potential exports as the Global Combat Ship (GCS) variant. Early planning targeted 10 to 12 units to maintain a balanced force structure amid fiscal constraints from the 1998 Strategic Defence Review, which had already reduced surface escort numbers.[10][11][9] International collaboration efforts, including the Project Horizon (Common New Generation Frigate) with France and Italy initiated after the NATO Frigate '90s program collapsed, were pursued to share development costs but abandoned by the UK on April 26, 1999, due to divergent national priorities and a preference for sovereign control over design and industrial base implications. This shift refocused the program domestically, with BAE Systems awarded an assessment phase contract in the early 2000s to refine concepts balancing high-end warfighting against emerging peer threats, such as resurgent Russian submarine capabilities in the North Atlantic.[10][8]Design Evolution and Global Combat Ship Concept
The design of the Type 26 frigate evolved from mid-1990s concepts aimed at replacing the Royal Navy's Type 23 class, initially termed Type 23(R) or Future Escort, with early work commencing in 1994.[10] Following the 1998 Strategic Defence Review, which prioritized expeditionary capabilities over pure anti-submarine warfare (ASW), the program was restructured as the Future Surface Combatant (FSC), incorporating exploratory designs such as trimaran hulls tested through the RV Triton research vessel trials from 2000 to 2002.[10][7] By 2006, under the Sustained Surface Combatant Capability (S2C2) initiative, proposals included variant-specific configurations—C1 for ASW, C2 for stabilization operations, and C3 for patrol duties—but the C3 was abandoned in 2010 amid cost constraints, leading to a consolidated Type 26 design blending ASW primacy with general-purpose flexibility.[10] In March 2010, BAE Systems received a £127 million contract for the assessment phase, shifting to a conventional monohull for improved modularity and export viability, with the core design unveiled in August 2012 and finalized by 2013.[11][7] The 2010 Strategic Defence and Security Review affirmed eight ASW-focused ships, while the 2015 review reduced the fleet to eight Type 26 vessels, supplemented by lighter Type 31 frigates for non-ASW roles.[10] The Global Combat Ship (GCS) concept reframes the Type 26 as an adaptable, export-oriented platform, emphasizing a modular mission bay for rapid integration of mission-specific equipment, such as unmanned vehicles, special forces support, or enhanced strike capabilities, beyond the UK's ASW emphasis.[11] This design philosophy, influenced by multinational efforts like the NATO Frigate for the 1990s (NFR-90) from 1979 to 1990, enables customization for anti-air warfare, surface strike, or humanitarian tasks through scalable vertical launch systems and reconfigurable spaces.[10] For international partners, the GCS facilitates tailored variants: Australia adopted it for the Hunter-class under Project SEA 5000 in 2019, incorporating local combat management systems, while Canada selected it for the Canadian Surface Combatant program in 2018, prioritizing interoperability with allied forces.[10][11] Construction milestones underscored the evolution, with long-lead items ordered in August 2015, the first steel cut for lead ship HMS Glasgow on 20 July 2017 under a £3.7 billion contract for the initial three hulls, and subsequent £4.2 billion awarded in 2022 for the remaining five.[11][7] The design's acoustic quieting, combined diesel-electric or gas (CODLOG) propulsion, and integrated sensor suites reflect iterative refinements to counter evolving submarine threats, particularly in the North Atlantic.[7]Major Program Milestones
The Type 26 frigate program traces its origins to the Future Surface Combatant (FSC) initiative launched in 1998 to replace aging Royal Navy frigates.[11] Initial Gate approval for the evolved program was granted by the Ministry of Defence on 18 March 2010, formalizing early development efforts.[12] Main Gate 1 approval followed in early 2015, initiating the Demonstration Phase on 1 April 2015 and enabling procurement of long-lead items in August 2015.[8] A £3.7 billion contract for the first three frigates was awarded to BAE Systems on 2 July 2017, with steel-cutting for the lead ship, HMS Glasgow, commencing shortly thereafter in July 2017.[7] Construction progressed steadily, culminating in the launch of HMS Glasgow on 25 November 2022.[13] The vessel was officially named HMS Glasgow on 22 May 2025 at BAE Systems' Scotstoun shipyard.[14] In November 2022, a £4.2 billion contract was awarded for the remaining five frigates, securing the full batch of eight ships.[15] Steel was cut for the second ship, HMS Cardiff, in August 2019, and for the first Batch 2 vessel in April 2023.[11][16] HMS Glasgow is scheduled for contractors' sea trials by late 2025 or early 2026, with handover to the Royal Navy expected by the end of 2026 and initial operating capability targeted for 2028.[14] All eight frigates are projected to enter service between 2028 and 2035.[17] Export milestones include Australia's selection of the Type 26-based Hunter-class in 2018, with construction contracts awarded in June 2024, and Norway's confirmation of acquiring at least five frigates on 31 August 2025, with deliveries starting in 2030.[18][19]Design and Specifications
Hull, Dimensions, and Propulsion
The Type 26 frigate employs a steel hull optimized for anti-submarine warfare, featuring angular lines to reduce radar cross-section and a low acoustic signature through advanced noise-reduction measures in the hull form and appendages.[11][20] The design includes high forward freeboard for improved seakeeping in rough seas and a transom stern with a small flap to minimize drag and cavitation.[20] Key dimensions include an overall length of 149.9 meters and a beam of 20.8 meters.[11][20] Official displacement is stated as 6,900 tonnes, though some analyses suggest full-load figures approach 8,000 tonnes based on comparative naval architecture assessments.[11][8] The hull supports a maximum speed exceeding 26 knots and a range greater than 7,000 nautical miles at economical speeds.[11] Propulsion is provided by a combined diesel-electric or gas (CODLOG) system, enabling efficient cruising in diesel-electric mode for stealthy operations and high-speed sprints via direct gas turbine drive.[11][21] The configuration consists of one Rolls-Royce MT30 gas turbine for boost propulsion, four MTU 20V 4000 M53B high-speed diesel generators supplying electrical power to two electric motors driving fixed-pitch propellers, and an exhaust after-treatment system to limit nitrogen oxide emissions.[11][21] This setup prioritizes ultra-quiet performance during anti-submarine missions by isolating propulsion machinery and using electric drive for minimal underwater radiated noise.[21]Sensors, Electronics, and Combat Management
The Type 26 frigate's combat management is handled by BAE Systems' INTeACT system, customized for the class with an open-architecture design that enables software-based upgrades via downloadable modules accessible through ship-wide tablets.[20] This system integrates data from sensors, weapons, and external networks to support decision-making in anti-submarine, air defense, and surface warfare roles.[20][11] Primary surveillance is provided by the BAE Systems Type 997 Artisan 3D radar, mounted on a composite mast approximately 35 meters above the waterline, offering a maximum detection range of about 200 km, the ability to track over 800 targets simultaneously, resistance to electronic countermeasures, and support for missile engagements via platform data link terminals.[20][11] Supplementary navigation radars include Terma SCANTER systems.[11] For anti-submarine warfare, the class features a hull-mounted Sonar 2150 active/passive array in a fibreglass bow dome, supplemented by a towed array sonar with an active low-frequency body and passive tail deployed from a quarterdeck winch, derived from the Sonar 2087 system for long-range submarine detection.[20][11][22] In July 2023, the UK Ministry of Defence contracted for five additional Type 2150 units to equip the fleet, enhancing passive and active detection while extending maintenance intervals.[22] Electronic warfare capabilities are delivered through the Royal Navy's Maritime Electronic Warfare System Integrated Capability (MEWSIC) program, incorporating UAT Mod 2.3 radar electronic support measures receivers on the mainmast and Shaman communications electronic support measures for signals intelligence.[20] Decoy launchers include fixed Sea Gnat systems for infrared and radar decoys, the Ultra Sonar 2170 surface ship torpedo defense, and next-generation N-POD dispensers.[20] Each frigate will receive two Ancilia 105 mm decoy launchers as part of MEWSIC integration.[23] Electro-optical surveillance is managed by three Chess Dynamics Sea Eagle FCEO directors: one for 127 mm gun fire control and one each for the 30 mm remote weapon stations, providing identification and tracking in visual and infrared spectra.[20] Communications are facilitated by Rohde & Schwarz NAVICS integrated systems, encompassing tactical voice, satellite, and video teleconferencing links, with masts optimized for UHF, VHF, and satellite reception.[20][11] Navigation and bridge functions use Raytheon Anschütz integrated systems.[11]Armament and Weapons Systems
The Type 26 frigate features a modular armament suite emphasizing anti-submarine warfare support through helicopter integration, complemented by point air defense and emerging long-range strike capabilities. The ship's fixed weapons include a forward-mounted medium-caliber gun for surface and limited anti-air engagements, vertical launch systems for missiles, close-in weapon systems, and smaller automated guns for force protection. Torpedo delivery relies primarily on embarked aircraft rather than dedicated shipboard tubes, reflecting the design's focus on aviation-centric ASW operations.[20][24] The main gun is a single BAE Systems Mk 45 Mod 4A 127 mm (5-inch) turreted naval gun, installed forward on the superstructure. This automated system includes a 20-round ready-service magazine and supports high-explosive shells weighing up to 31.5 kg with muzzle velocities of 823–1,051 m/s, enabling engagements against surface targets, drones, and fast attack craft at ranges exceeding 20 km. The Mk 45 replaces the Royal Navy's legacy 114 mm Mk 8 guns, offering improved NATO interoperability, reliability, and precision-guided munitions compatibility, such as potential Kingfisher sonobuoys or depth charges for ASW. Integration began on lead ship HMS Glasgow in September 2024 at BAE Systems' facilities.[25][20] For air defense, the frigate mounts two 24-cell Sea Ceptor vertical launch systems (VLS) configured for 48 Common Anti-Air Modular Missiles (CAMM), providing 360-degree coverage with an engagement range of approximately 25 km against aircraft, drones, and limited anti-ship threats. These dedicated modules, positioned forward and amidships, enhance task group protection compared to the 32 CAMM on Type 23 predecessors. A separate 24-cell Mk 41 strike-length VLS amidships supports the Future Cruise/Anti-Ship Weapon (FC/ASW), a supersonic or hypersonic missile under development for 2028 service entry, enabling land-attack and anti-surface strikes; it may also accommodate quad-packed additional Sea Ceptor (up to 96 more missiles) or U.S.-origin weapons like Vertical Launch Anti-Submarine Rockets (VLA) pending procurement decisions.[20][24][1] Close-in defense includes two Phalanx Block 1B 20 mm CIWS mounts for intercepting incoming missiles and aircraft, with potential future upgrades to directed-energy weapons. Force protection is provided by two 30 mm Automated Small Calibre Guns (ASCG) for engaging small surface threats, supplemented by mounts for 0.5-inch heavy machine guns. The design lacks fixed torpedo tubes; Sting Ray lightweight torpedoes are deployed via embarked Merlin or Wildcat helicopters, though mission bay containers may enable limited ship-launched options in the future. Decoy systems comprise fixed DLH Sea Gnat launchers, the Ultra Sonar 2170 Surface Ship Torpedo Defence system, and Naval Passive Off-Board Decoys (N-POD) for countering torpedoes and missiles.[20][24]Mission Bay and Modular Capabilities
The mission bay of the Type 26 frigate comprises a flexible stern compartment designed to accommodate interchangeable mission modules, enabling rapid reconfiguration for diverse operational roles beyond primary anti-submarine warfare.[26] This space supports the deployment of unmanned underwater vehicles (UUVs), rigid-hulled inflatable boats (RHIBs), and towed array sonar systems via an integrated stern ramp, facilitating launch and recovery in various sea states.[11] The bay's capacity totals 150 tonnes of containers or equipment, with a maximum weight of 18 tonnes per 40-foot equivalent unit (FEU), allowing for standardized payloads such as modular containers for humanitarian aid, including food, medical supplies, and water purification systems.[27] Modular capabilities are enhanced by the Mission Bay Handling System (MBHS), supplied by Rolls-Royce under a contract awarded on August 13, 2024, for Batch 2 vessels, which transforms the bay into a multi-purpose area for handling and stowing equipment.[28] The system supports spiral development of capabilities through a standardized footprint for modules or pods, permitting upgrades without major ship alterations and adaptation to emerging threats.[29] Integration with the adjacent hangar enables combined operations involving multiple helicopters, UUVs, and surface craft, providing versatility for expeditionary tasks, special forces insertion, or disaster relief.[2] This modularity aligns with the frigate's design as a multi-mission platform, prioritizing empirical flexibility over fixed configurations to address causal operational demands in contested environments.[26]Operational Roles and Capabilities
Primary Anti-Submarine Warfare Focus
The Type 26 frigate serves as the Royal Navy's premier platform for anti-submarine warfare (ASW), optimized to detect, track, and neutralize submarine threats in high-threat environments such as the North Atlantic.[11] It replaces the Type 23 Duke-class frigates, which have fulfilled a similar role since the 1990s, with the Type 26 incorporating enhanced acoustic stealth and sensor integration to maintain superiority against modern diesel-electric and nuclear submarines.[30] This focus aligns with its designation as a "submarine hunting" warship, capable of escorting high-value assets like aircraft carriers and ballistic missile submarines while conducting independent ASW patrols.[31][11] Central to its ASW capability is an advanced sonar suite, including the low-frequency active-passive towed array sonar (Sonar 2087), inherited and upgraded from the Type 23 class for long-range submarine detection and classification beyond 100 kilometers in varying oceanographic conditions.[11] Complementing this is a hull-mounted sonar system, such as Ultra Maritime's Sea Searcher, providing medium-range active and passive search capabilities for closer engagements and torpedo warning.[32] The frigate also integrates a comprehensive torpedo defense system with decoys and countermeasures to evade incoming threats, enabling sustained operations in contested waters. Aviation assets amplify the Type 26's ASW reach, with a through-deck hangar and flight deck accommodating one Merlin HM2 or Wildcat helicopter equipped for sonar dipping, sonobuoy deployment, and anti-submarine torpedo launches.[11] These rotary-wing platforms extend sensor coverage and enable rapid response strikes, supporting missions that demand persistent underwater surveillance and engagement.[15] Armament for ASW includes two 324mm lightweight torpedo tubes firing MU90 Impact torpedoes, which feature advanced guidance for high-speed intercepts of submerged targets.[11] This configuration, combined with modular mission bay storage for additional sonobuoys and decoys, allows the Type 26 to adapt to evolving submarine tactics, prioritizing endurance and precision over volume firepower.[15]Secondary Air and Surface Warfare Roles
The Type 26 frigate's air warfare capabilities emphasize point defense rather than area air defense, providing self-protection and limited support to task groups against aircraft, drones, and incoming missiles. It is equipped with 48 Common Anti-Air Modular Missiles (CAMM), also known as Sea Ceptor, launched from Sylver A50 vertical launch system (VLS) cells, offering a medium-range surface-to-air capability with an effective range exceeding 25 km and the potential for extended-range variants like CAMM-ER.[20] The integrated Artisan 3D radar, optimized for medium-to-long range air and surface surveillance, supports target detection and tracking in cluttered environments, enabling rapid engagement. Additionally, two Phalanx Close-In Weapon Systems (CIWS) provide a final layer of defense against sea-skimming missiles and close threats, while the embarked Wildcat helicopter can deploy Martlet air-to-surface missiles for short-range air interdiction.[1] In surface warfare, the Type 26 supports offensive and defensive operations against enemy vessels through a combination of missiles, artillery, and aviation assets, though these roles are secondary to its anti-submarine focus. The planned armament includes eight Kongsberg Naval Strike Missiles (NSM), which offer a range of approximately 185 km and precision strike capabilities against surface targets, replacing the retiring Harpoon Block II system across the Royal Navy fleet.[20][33] A BAE Systems Mk 110 57 mm naval gun provides medium-caliber fire support for engagements up to 20 km, with high rate-of-fire and anti-air modes for versatility.[1] Helicopters such as the Wildcat, armed with Sea Venom anti-ship missiles, extend the frigate's reach for over-the-horizon targeting, while Sting Ray torpedoes from the mission bay or helicopter can address fast attack craft in littoral scenarios.[2] These systems integrate via the MK2E combat management system, allowing coordinated responses in multi-threat environments, though the frigate lacks the magazine capacity for sustained high-intensity surface engagements compared to dedicated destroyers.[11]Support for Expeditionary and Multi-Domain Operations
The Type 26 frigate enhances expeditionary operations through its reconfigurable mission bay, a flexible hangar and deck space spanning approximately 1,000 square meters at the stern, designed to embark and launch modular payloads such as up to four 11-meter rigid-hulled inflatable boats (RHIBs), unmanned surface vessels (USVs), unmanned aerial vehicles (UAVs), and remotely operated underwater vehicles (ROVs). This setup supports littoral power projection, including the insertion of special forces or boarding teams into denied areas, as well as organic mine countermeasures or hydrographic survey capabilities via containerized mission modules.[27][34] In support of amphibious task groups, the frigate provides layered protection and enabling functions, such as anti-submarine screening for landing forces and surface strike options via Mk 41 vertical launch system cells for missiles like the Naval Strike Missile, extending reach into coastal zones up to 185 kilometers. Its endurance—over 11,000 nautical miles at 15 knots—and aviation facilities for a Wildcat or Merlin helicopter further enable sustained operations alongside assault ships, facilitating joint maneuvers in scenarios like those outlined in NATO's high-north strategies.[26][35] For multi-domain operations, the Type 26 integrates advanced C4ISR systems, including the Artisan radar and CMS-1 combat management system, to fuse sensor data across maritime, air, subsurface, and cyber domains, enabling real-time coordination with allied assets like P-8 Poseidon aircraft or ground forces in joint task forces. This digital backbone supports networked warfare, where the frigate acts as a node for sharing tactical pictures and directing unmanned systems, aligning with UK Ministry of Defence emphasis on agile platforms for full-spectrum multinational missions beyond core anti-submarine warfare.[36][37]International Partnerships and Variants
United Kingdom Royal Navy Program
The Royal Navy's Type 26 frigate program, designated the City-class, procures eight vessels optimized for anti-submarine warfare to replace the aging Type 23 frigates, enhancing the fleet's high-end combat capabilities.[1] The ships are named HMS Glasgow (F88), HMS Cardiff (F89), HMS Belfast (F90), HMS Birmingham, HMS Sheffield, HMS Newcastle, HMS Edinburgh, and HMS London.[1] Procurement began with a £3.7 billion contract awarded to BAE Systems on 7 July 2017 for the construction of the first three frigates at the company's Govan and Scotstoun shipyards in Glasgow, Scotland.[36] On 15 November 2022, the Ministry of Defence awarded BAE Systems a £4.2 billion contract for the second batch of five frigates, committing to the full eight-ship program with a total estimated value exceeding £8 billion.[38] As of October 2025, lead ship HMS Glasgow has completed launch in November 2022 and official naming in May 2025, advancing through fitting out at Scotstoun with contractors' sea trials slated for late 2025 or early 2026, handover to the Royal Navy by late 2026, and initial operating capability targeted for 2028.[39][14] HMS Cardiff is under assembly following steel cutting, while initial steel for batch two lead ship HMS Birmingham was cut in April 2023; the first three frigates are projected to achieve operational status before 2030, with the entire class entering service by 2035.[1][39][13]Royal Australian Navy Hunter-Class Variant
The Hunter-class frigate represents the Royal Australian Navy's (RAN) customized variant of the BAE Systems Type 26 Global Combat Ship, selected in 2018 under Project SEA 5000 Phase 2 to replace the ageing Anzac-class frigates with a fleet optimized for anti-submarine warfare (ASW) while incorporating enhanced multi-role capabilities.[40] Originally planned for nine vessels, the program was restructured to six frigates in 2023, aligning with broader naval priorities including AUKUS commitments for larger surface combatants.[3] Each ship displaces approximately 8,800 tonnes at full load, measures 150 metres in length, and achieves speeds exceeding 27 knots, enabling operations across Indo-Pacific theatres.[41] Adaptations from the baseline Type 26 design prioritize Australian sovereign capabilities and interoperability, including integration of the CEA Technologies CEAFAR active phased-array radar for superior air and surface tracking, a domestically developed combat management system, and vertical launch systems compatible with SM-2 and SM-6 missiles for extended-range air defence and limited ballistic missile defence.[42] Unlike the UK Royal Navy's ASW-focused Type 26, which emphasizes self-defence air warfare, the Hunter-class incorporates provisions for deep-strike land-attack missiles and terminal-phase ballistic missile interception, positioning it as a more versatile "all-rounder" platform without dedicated destroyer escorts in the RAN inventory.[43] The variant retains the Type 26's core ASW features, such as low-noise propulsion and modular mission bays for sonobuoys, torpedoes, and unmanned vehicles, but features hull modifications for Australian operational profiles, including enhanced endurance for independent deployments.[44] Construction is led by BAE Systems Maritime Australia at the Osborne Naval Shipyard in South Australia, with steel cutting for the lead ship, HMAS Hunter, commencing in June 2024 following Preliminary Design Review approval.[42] As of October 2025, over 50% of the first frigate's 78 structural units are in production just 15 months after steel cutting, with initial machinery unit consolidations completed and combat system testing slated to begin during build.[45] The program employs up to 2,600 personnel, with over 400 tradespeople hired in 2025 to ramp up capacity, and first delivery targeted for 2032 followed by operational service in 2034.[46] Early challenges, including design maturation from an immature Type 26 baseline, have prompted cost overruns and delays, though recent milestones indicate stabilized progress under government oversight.[47]Royal Canadian Navy Adaptation
The Royal Canadian Navy's adaptation of the Type 26 frigate, designated as the River-class destroyer under the Canadian Surface Combatant (CSC) program, was selected in October 2018 as the baseline design from BAE Systems' Global Combat Ship offering. This choice followed a competitive process under the National Shipbuilding Strategy, with Lockheed Martin Canada awarded the contract as the prime integrator, incorporating the Type 26 hull form, propulsion system, and modular mission bay while customizing for Canadian operational requirements. The program aims to procure 15 vessels to replace the aging Halifax-class frigates, with an estimated total cost of C$60-80 billion, emphasizing multi-mission capabilities including anti-submarine warfare, air defense, and surface strike.[48][49][50] Key adaptations distinguish the Canadian variant from the Royal Navy's Type 26, reclassifying it as a destroyer due to enhanced sensors and armament for blue-water operations across the Atlantic, Pacific, and Arctic. The ships feature the Lockheed Martin SPY-7(V)1 radar for active electronically scanned array detection, integrated with an Aegis-like combat management system for superior air and missile defense, supporting vertical launch systems (VLS) capable of hosting SM-2, SM-6, and Evolved SeaSparrow missiles. Armament includes a 127 mm main gun, Naval Strike Missiles for anti-ship roles, and provisions for unmanned systems, with a reduced crew of approximately 118-140 personnel enabled by automation advancements over the UK design's 157-181. The hull is extended slightly for additional fuel and endurance, prioritizing sovereignty and interoperability with NATO allies while accommodating Canadian-specific equipment like the CH-148 Cyclone helicopter.[51][52][53] Construction is led by Irving Shipbuilding in Halifax, Nova Scotia, with steel cutting for the lead ship, HMCS River, commencing in June 2024 and design maturation ongoing as of October 2025. The adaptation emphasizes industrial benefits, projecting annual GDP contributions of C$719.3 million and sustaining 5,250 jobs yearly through 2039, though critics note risks of cost overruns from custom integrations. Delivery of the first vessel is targeted for the early 2030s, with full operational capability extending into the 2040s, reflecting a strategic pivot toward high-end warfighting amid evolving threats.[54][51][55]Norwegian Frigate Acquisition
On 31 August 2025, the Norwegian government announced the selection of the United Kingdom as its strategic partner for acquiring new anti-submarine warfare (ASW) frigates based on the Type 26 design, marking Norway's largest-ever military procurement.[56][19] The decision followed a competitive evaluation process involving bids from Germany, France, and the United States, with the Type 26 chosen for its proven ASW capabilities tailored to threats in the North Atlantic and Arctic regions.[57][58] The program aims to replace Norway's five Nansen-class (F310) frigates, commissioned between 2006 and 2011, which have faced operational limitations in modern ASW scenarios amid heightened Russian submarine activity near Norwegian waters.[35] At least five Type 26 variants will be procured, with an estimated total value of £10 billion (approximately $13.5 billion), enabling a combined Anglo-Norwegian ASW fleet of at least 13 ships alongside the Royal Navy's eight City-class frigates.[56][58] Norway targets delivery of the first vessel by 2029 to address urgent capability gaps, emphasizing the Type 26's advanced sonar systems, towed array, and mission bay for underwater unmanned vehicles.[56][19] Strategic interoperability was a key factor, as the identical platforms will facilitate joint operations, shared logistics, and training between the Royal Norwegian Navy and Royal Navy, enhancing NATO's high-north deterrence without requiring extensive modifications.[59][60] The agreement forms part of a broader UK-Norway defense partnership, including potential co-production elements to integrate Norwegian industry, such as local assembly or subsystem manufacturing, as outlined in a 25 October 2025 industry strategy to bolster domestic shipbuilding.[60][61] This acquisition positions the Royal Norwegian Navy as the fourth operator of the Type 26/Global Combat Ship platform, following the United Kingdom, Australia, and Canada, and underscores a preference for ASW specialization over multi-role designs from competitors like France's FDI or Germany's MEKO A-200.[19][35] While the deal promises enhanced survivability through the Type 26's stealth features and modular mission systems, Norwegian officials have noted ongoing evaluations for air defense integrations to complement the primary ASW role.[62]Other Export Prospects
BAE Systems has positioned the Type 26 frigate, marketed internationally as the Global Combat Ship, for broader export opportunities beyond confirmed programs with Australia, Canada, and Norway. The design's modular architecture and emphasis on anti-submarine warfare appeal to navies seeking high-end capabilities for contested maritime environments, though its estimated unit cost exceeding £1 billion per ship limits appeal to budget-constrained buyers. As of October 2025, no additional contracts have materialized, but historical interest from South American navies highlights untapped potential.[63] Brazil has been cited as a prospective customer, given its navy’s need to modernize aging frigates such as the Type 22-class vessels, which are approaching decommissioning. The Type 26's advanced sonar suite, including the low-frequency active sonar, aligns with Brazil's requirements for blue-water operations in the South Atlantic, potentially supporting offshore resource protection. However, Brazil's procurement decisions have favored cost-effective alternatives, with recent focuses on domestic shipbuilding and partnerships like those with South Korea for larger surface combatants, tempering immediate prospects for the Type 26.[64][63] Chile represents another identified market, where the Type 26 could replace the navy's aging Almirante-class (ex-Type 23) frigates, acquired second-hand from the UK in the 2000s. Chile's historical preference for British designs, combined with the Type 26's interoperability advantages through shared systems like the Artisan radar and Sea Ceptor missiles, positions it competitively. Nonetheless, Chile's fiscal constraints and evaluations of multi-role frigates from European competitors, such as the French FDI or Dutch ASW variants, have not yet led to formal bids or selections for the Type 26 as of late 2025.[64][63] Earlier speculation included New Zealand, whose navy operates smaller Anzac-class frigates due for replacement around 2030, but no active pursuit of the Type 26 has been reported recently, with preferences leaning toward less expensive platforms amid defense budget debates. Export challenges for the Type 26 include its specialized ASW focus, which may not align with surface warfare priorities in regions like Southeast Asia or the Middle East, and competition from lower-cost offerings like the US Constellation-class or European MEKO designs. The Norwegian deal's £10 billion valuation for five units underscores economies of scale for future sales, potentially incentivizing further interest if production efficiencies reduce per-unit costs below current benchmarks.[65][66]Construction and Production Status
Shipbuilding Facilities and Contractors
BAE Systems serves as the prime contractor for the construction of the Royal Navy's eight Type 26 frigates, with primary shipbuilding occurring at its Govan and Scotstoun facilities on the River Clyde in Glasgow, Scotland.[67] Hull sections are fabricated at Govan, followed by outfitting and integration at Scotstoun, supporting approximately 2,000 jobs in Scotland and 4,000 across the UK.[68] In June 2025, BAE Systems opened the Poseidon assembly hall at Govan, a 170m by 80m climate-controlled facility enabling simultaneous construction of two frigates side-by-side to accelerate production.[69] For the Royal Australian Navy's Hunter-class variant, BAE Systems Maritime Australia leads construction at the Osborne Naval Shipyard in Adelaide, South Australia, where steel cutting for the first vessel commenced in June 2024.[45] This site, expanded to support the program, is projected to sustain over 2,600 jobs.[70] The Royal Canadian Navy's River-class destroyers, derived from the Type 26 design, are being built by Irving Shipbuilding Inc. as prime contractor at its Halifax Shipyard in Nova Scotia, with design support from Lockheed Martin Canada based on BAE Systems' platform.[71] Construction activities initiated in 2024 for this 15-ship program.[72] Norway's planned acquisition of five Type 26 frigates involves BAE Systems as the manufacturer, with production anticipated at UK facilities under a £10 billion agreement announced in August 2025, emphasizing supply chain integration for Norwegian industry.[73]Current Build Progress as of October 2025
As of October 2025, construction of the Royal Navy's Type 26 frigates continues at BAE Systems' facilities on the River Clyde in Glasgow, with five of the eight planned vessels having had steel cut following the ceremony for HMS Sheffield on 28 November 2024.[74] The lead ship, HMS Glasgow, is in the advanced fitting-out stage at the Scotstoun yard, where integration of its combat management system and other key equipment is progressing toward anticipated sea trials later in the year.[75] The overall programme remains aligned with requirements for the first vessels to achieve operational capability by 2028.[39] HMS Cardiff, the second frigate, entered the water for initial outfitting in September 2024 and continues structural and systems installation in dry dock.[76] The third vessel, HMS Belfast, benefits from the new indoor assembly hall opened in June 2025, enabling full consolidation under cover to mitigate weather-related delays.[77] Subsequent ships, including HMS Sheffield, are in early build phases, with parallel production lines supporting increased throughput.[78] For export variants, the Royal Australian Navy's Hunter-class programme has reached a milestone where more than half of the 78 structural units for the lead ship are in production, just 15 months after steel cutting.[45] Norway's recently confirmed acquisition of at least five Type 26 frigates, valued at £10 billion and announced in August 2025, will see construction commence alongside Royal Navy ships at the Clyde yards, enhancing production efficiency through shared supply chains.[79] The Royal Canadian Navy's adaptation remains in the design and procurement phase, with no steel cut reported as of this date.Production Challenges and Resolutions
The Type 26 frigate program has encountered significant production delays, with the initial operational capability for the lead ship, HMS Glasgow, postponed by 12 months to October 2028.[39] These delays stem from complexities in fitting out phases, including cabling issues that deferred the activation of electrical switchboards from the first quarter of 2024.[80] Overall program slippage has been officially acknowledged by the UK Ministry of Defence, accompanied by cost overruns, though officials maintain the project remains aligned with revised baselines.[81] Supply chain disruptions and design integration challenges inherent to the vessel's advanced anti-submarine warfare systems have contributed to these setbacks, exacerbating workforce and facility constraints at BAE Systems' Govan and Scotstoun yards.[82] As of October 2025, while HMS Glasgow and HMS Cardiff are in fitting out, subsequent hulls like HMS Belfast continue structural assembly, highlighting uneven progress across the batch.[39] To address these issues, BAE Systems opened the Janet Harvey Hall assembly facility at Govan in June 2025, enabling parallel construction of multiple hulls and improved efficiency in modular integration.[75] The September 2025 agreement to supply five Type 26 frigates to Norway, valued at approximately £10 billion, facilitates concurrent production for export alongside Royal Navy vessels, potentially mitigating domestic delays through economies of scale and sustained yard utilization.[83] This international partnership, with the first Norwegian ship slated for delivery in 2030, is expected to stabilize the production pipeline despite initial risks of diverting resources from UK priorities.[84] Revised build schedules and enhanced investment in skilled labor have further supported incremental advancements, as evidenced by ongoing fitting out milestones.[85]Strategic Assessment and Controversies
Geopolitical and Deterrence Value
The Type 26 frigate's primary design emphasis on anti-submarine warfare (ASW) positions it as a critical asset for deterring submarine incursions by adversaries such as Russia in the North Atlantic and Arctic regions, where advanced sonar systems, towed array capabilities, and integration with Merlin or Wildcat helicopters enable persistent underwater threat detection and neutralization.[2] This capability directly supports NATO's maritime domain awareness and collective defense under Article 5, addressing the resurgence of Russian submarine activity since 2014, including patrols near undersea cables and energy infrastructure.[35] For the United Kingdom, the class replaces the aging Type 23 frigates with eight vessels optimized for high-intensity ASW operations, thereby sustaining the Royal Navy's role in securing sea lines of communication vital to European energy supplies and reinforcing deterrence through forward presence in contested waters.[86] Norway's August 31, 2025, selection of the Type 26 as its new frigate platform, involving at least five ships in a £10 billion deal, underscores the design's geopolitical value in bolstering NATO's northern flank against Russian Northern Fleet submarines operating from bases like Severomorsk.[87] The frigates' ASW focus aligns with Norway's strategic imperative to monitor the Barents Sea and GIUK Gap, where Russian Yasen-class submarines pose risks to allied reinforcements; shared logistics and training with the UK will enhance interoperability, allowing joint task groups to multiply deterrence effects without redundant national investments.[66] This partnership signals deepening transatlantic trust in UK defense technology over alternatives like U.S. or European bids, countering perceptions of industrial fragmentation within NATO amid heightened Russo-Western tensions.[88] Export adaptations extend the Type 26's deterrence footprint: Australia's Hunter-class variant, with nine planned ships (reduced from initial projections but incorporating SM-6 missiles for extended-range air and surface threats), contributes to Indo-Pacific stability by enabling ASW patrols amid Chinese naval expansion, including submarine deployments challenging freedom of navigation in the South China Sea.[89] Canada's River-class destroyers, based on the Type 26 hull, prioritize ASW for Atlantic and Arctic domains, deterring hybrid threats from Russian or Chinese vessels probing northern approaches.[19] Collectively, these programs foster alliance cohesion through common architecture, permitting seamless data-sharing via Link 16 and collaborative operations, which amplify regional deterrence by demonstrating credible, scalable naval power projection without escalating to overt confrontation.[90]Economic Impacts and Industrial Benefits
The Type 26 frigate programme sustains approximately 4,000 skilled jobs across the United Kingdom, with nearly 2,000 positions located in Scotland at BAE Systems' facilities in Govan and Scotstoun.[68][91] These roles encompass direct shipbuilding, engineering, and apprenticeships, contributing to the long-term viability of the UK's surface warship construction capacity. Additionally, the programme supports a supply chain involving around 400 British companies, with contracts valued at over £1 billion fostering innovation and employment in subsystems such as propulsion, sensors, and structural components.[92][93] Export variants amplify these industrial benefits for the UK economy. Workshare on the Royal Australian Navy's Hunter-class frigates and the Royal Canadian Navy's adaptation is estimated to generate £6 billion in economic value through technology transfer, component supply, and design support.[94] The August 2025 agreement to supply four Type 26 frigates to Norway, valued at £10 billion, represents the largest warship export deal in UK history by value and sustains an additional 4,000 jobs while engaging the domestic supply chain.[66][90] This deal also promotes opportunities for small and medium-sized enterprises (SMEs) in advanced manufacturing, enhancing the competitiveness of the UK's defence sector.[73] In Australia, the Hunter-class programme has injected $2.2 billion into the national economy as of October 2025, primarily through local construction at Osborne shipyard, which utilises Australian steel and components to build sovereign capability.[45] Projections indicate a total GDP contribution of $17 billion over the programme's life, supporting thousands of jobs in shipbuilding, engineering, and related industries while stimulating regional development in South Australia.[95] These efforts underscore the Type 26 design's role in revitalising national shipbuilding infrastructures, though sustained investment in skills and facilities remains essential to realise full economic returns.[96]Criticisms on Costs, Delays, and Procurement
The Type 26 frigate program has encountered significant delays, with the first vessel, HMS Glasgow, originally slated for operational service in the early 2020s but now projected for 2028 following repeated postponements attributed to supply chain disruptions and design refinements.[39] A specific incident involved the principal anti-submarine warfare gearbox, delivered late by the supplier and failing to meet performance standards, necessitating costly redesigns and modifications that added £233 million to the program's expenses, equivalent to nearly a quarter of a billion pounds at the time.[97] This overrun stemmed from the Ministry of Defence (MoD) receiving notification of the gearbox failure 20 months after initial detection, highlighting deficiencies in contractor oversight and information flow within the procurement process.[82] Parliamentary scrutiny has labeled the program's management as inadequate, with a 2023 inquiry by the House of Commons Defence Committee citing the delays and financial strains as symptomatic of broader systemic flaws in UK defence acquisition, including optimistic initial timelines and insufficient contingency planning for industrial bottlenecks.[98] By February 2025, the MoD acknowledged ongoing delays and cost pressures but maintained that the project adhered to revised baselines, though critics argued this reflected a pattern of shifting goals rather than effective resolution.[81] Manufacturing challenges persisted into mid-2025, with reports of protracted timelines exacerbating pressures on the Royal Navy's surface fleet capacity amid Type 23 frigate retirements.[35] Procurement criticisms extend to decision-making rigidity and supplier dependencies, as evidenced by the gearbox episode, where reliance on a single vendor without robust fallback mechanisms amplified risks.[99] The August 2025 agreement to export Type 26 variants to Norway, valued at approximately £10 billion for at least five ships, raised concerns over potential further slippage for UK hulls due to shared production lines at BAE Systems' facilities, with discussions ongoing to mitigate impacts on domestic priorities.[100] Defence analysts have attributed these issues to inherent complexities in concurrent design and build phases for a high-technology platform, compounded by post-Brexit supply chain vulnerabilities and inflation-driven material costs, though MoD officials countered that export successes validate the design's maturity despite UK-specific execution hurdles.[66]Capability Debates and Comparisons
The Type 26 frigate prioritizes anti-submarine warfare (ASW), incorporating a low-acoustic-signature hull, propulsion system, bow-mounted sonar in a fibreglass dome, and towed array sonar for submarine detection and tracking, complemented by support for ASW helicopters such as the Merlin.[20] Its sensors include the Type 997 Artisan radar, capable of tracking up to 800 targets at ranges exceeding 200 km with electronic countermeasure resistance, while weapons encompass 48 Sea Ceptor vertical launch system (VLS) cells for point air defense, 24 Mk 41 strike-length VLS cells compatible with anti-ship or land-attack missiles, and a 127 mm Mk 45 gun.[20] At 149.9 m in length, 20.8 m beam, and 6,900 tonnes displacement, it accommodates a core crew of 157 with capacity for 50 additional personnel, enabling extended operations up to 60 days or 7,000 nautical miles.[20] Comparisons to the Royal Navy's Type 31 frigate underscore the Type 26's specialization in high-end warfighting versus the Type 31's role in lower-threat patrol and presence missions.[101] The Type 26 features greater modularity for missions including counter-piracy and disaster relief, with superior ASW sensors and armament including 48 Sea Ceptor cells and the 127 mm gun, whereas the Type 31 relies on 12 Sea Ceptor cells, a 57 mm gun, and lacks initial strike-length VLS, positioning it as a cost-effective complement rather than a direct peer.[101] In Norway's 2025 frigate procurement, the Type 26 prevailed over competitors like the French FDI, US Constellation (FREMM-derived), and German F127, valued for its ASW optimization—including the 2087 towed array and CODLOG propulsion—suited to North Atlantic threats from Russian submarines, despite limited area air defense restricted to short-range Sea Ceptor.[35] Critics highlighted its point-defense focus as inferior to the FDI's 32 VLS cells with longer-range Aster missiles or the F127's 64 cells and AN/SPY-6 radar for ballistic missile defense, and noted higher crew demands relative to multi-role alternatives, though its 157-person complement proved more efficient than the F127's ~220.[35] Debates on versatility question the Type 26's specialization, with advocates citing its mission bay for unmanned underwater vehicles (UUVs), counter-unmanned aerial systems, and potential Naval Strike Missile integration to extend surface and ASW reach beyond pure submarine hunting.[26] Detractors argue its segregated VLS configuration—lacking multipurpose cells—and reliance on short-range Sea Ceptor limit firepower for its 7,700-tonne full-load displacement compared to peers like the US Arleigh Burke destroyer (96 cells) or even smaller vessels with denser, more flexible armaments, potentially requiring task group support for layered defenses.[102] These trade-offs reflect a deliberate emphasis on ASW excellence amid NATO priorities, though they fuel discussions on whether broader multi-domain capabilities justify the design's constraints.[35]| Feature | Type 26 | Type 31 | FDI (Belharra-class) |
|---|---|---|---|
| Displacement (tonnes) | 6,900 | ~5,700 | ~4,500 |

Planned Fleet and Naming
Naming Conventions Across Navies
The Royal Navy's Type 26 frigates, designated as the City-class, adhere to the longstanding convention of naming frigates after cities within the United Kingdom, a practice rooted in historical naval traditions to evoke regional ties and heritage.[11] This includes vessels such as HMS Glasgow, HMS Cardiff, HMS Belfast, HMS Birmingham, HMS Sheffield, HMS Newcastle, HMS Edinburgh, and HMS London, with selections approved by the Ships' Names and Badges Committee to ensure continuity and public resonance.[11][31] In the Royal Australian Navy, the Hunter-class variant employs names drawn from major Australian regions and historical explorers, emphasizing national geography and exploration legacy, as seen in the initial ships HMAS Hunter, HMAS Flinders (II), and HMAS Tasman.[103][104] The class designation itself underscores the frigates' primary anti-submarine warfare role, diverging from prior RAN frigate naming after battles (e.g., Anzac-class) toward regionally evocative identifiers for strategic surface combatants.[3] The Royal Canadian Navy's adaptation, reclassified as the River-class destroyer in June 2024, follows a convention of naming after major Canadian rivers to symbolize national unity and the waterways' historical role in connectivity and development.[55][105] This approach, recommended by the RCN's Ship Naming Committee, prioritizes public engagement through familiar geographic features, marking a shift from previous patterns like tribal or city names to highlight rivers as enduring natural agents.[106][107]Detailed List of Ships by Commissioning Navy
