Future of the Royal Navy

Royal Navy The following is a list of vessels ordered, under construction or undergoing sea trials within the United Kingdom, and destined for the Royal Navy: Royal Fleet Auxiliary The following is a list of vessels ordered for the Royal Fleet Auxiliary: • ==Ships==

Destroyers and frigates In the 2010 Strategic Defence and Security Review (SDSR) a replacement programme was authorised for the Navy's fleet of thirteen Type 23 frigates. In 2012, BAE Systems Naval Ships was awarded a contract to design the replacement, known as the Type 26 Global Combat Ship (GCS). It was planned that two variants of the class would be built: five general purpose frigates and eight anti-submarine warfare frigates. According to estimates as of 2022, the first Type 26 frigate is to commission in late 2026 and the last commissioning in around 2034, whilst the Type 23s are gradually phased out. However, in October 2022, the Secretary of State for Defence, Ben Wallace, indicated that Initial Operating Capability for the first ship in the class would only be reached in 2028. Eight Type 26 frigates will be built. The five remaining ships will be covered by a new class of lighter, flexible general purpose frigate, known as the Type 31e frigate or General Purpose Frigate (GPFF). The slower than planned introduction of both the Type 26 and Type 31, coupled with the pending retirement dates for the Type 23, will lead to a reduction of Royal Navy frigate numbers to just seven frigates by the end of 2025. Reductions were partly confirmed in the 2021 defence white paper with the announcement that two of the Type 23s would, in fact, be retired early. Nevertheless, the at sea availability of ships (both destroyers and frigates) within this smaller force was projected as likely increasing as vessels completed their life extension refits. By the latter 2020s and 2030s it had been anticipated that overall numbers could rise again as the replacement vessels enter service. In 2021 in a written answer provided to the House of Commons Defence Select Committee, the First Sea Lord, Admiral Tony Radakin, suggested that older Type 23 frigates would be retained in service longer than anticipated in order to ensure that escort numbers did not fall below 17 ships (6 destroyers and 11 frigates) and start to rise back above 19 escorts starting in the latter 2020s. The objective of the 2021 white paper was to have 24 frigates and destroyers in service by the "early 2030s", though some argued that a date of 2035 was more likely. This is to be achieved through the construction of yet another class of frigate, the Type 32. However, as of 2023 the Royal Navy is experiencing significant recruiting challenges with a net drop of some 1,600 personnel (4 percent of the force) from mid-2022 to mid-2023. This was posing a significant problem in the ability of the navy to meet its commitments. Reports in early 2024 suggested that this may in fact contribute to the early retirement of some vessels, including the oldest Type 23 frigates. In May 2024, it was indicated that two frigates, and would indeed be retired reducing the total number of active frigates to nine. In August 2024, it was reported that, at the start of her upkeep period, significant problems had been found in HMS and that she might now be "beyond economical repair". No further details were included but the announcement was made in the context of restoring the United Kingdom as "the foremost naval power in Europe" and to "spur a shipbuilding renaissance". As of late 2022, the Type 32 frigate project was reported to be facing significant funding pressures. The November 2022 report of the National Audit Office on The Equipment Plan 2022-2032 stated that in July 2022 "Navy Command withdrew its plans for Type 32 frigates and MRSS because of concerns about unaffordability. The revised costing profile is likely to be significantly higher". The March 2021 defence white paper also announced that a new class of air defence destroyer, the Type 83, would be designed to replace the Type 45 destroyer with the aim of achieving initial delivery in the latter 2030s. In the interim, in July 2021 it was announced that the Type 45 destroyers would be upgraded through the addition of 24 cells for the Sea Ceptor surface-to-air missile system. The Type 45s were reported as likely to be incrementally upgraded between 2026 and 2032. Mine countermeasures and Hydrographic Capability (MHC) The 2015 SDSR specified that only 12 mine-counter measure vessels were planned to exist in Joint Force 2025. The three oldest Sandown-class minehunters were decommissioned. At one point it was anticipated that the UK and France would collaborate on a Maritime Mine Counter Measures project. At DESI 2017, the First Sea Lord mentioned that the Royal Navy aimed to accelerate the incremental delivery of future mine countermeasures and hydrographic capability (MHC) programme. All of these plans notwithstanding, in 2020 the parliamentary National Audit Office (NAO) noted that no funding had been allocated in the 2019 to 2029 period to replace the Navy's mine countermeasures capability. The 2021 defence white paper subsequently confirmed that all existing MCMV vessels would be phased out in the 2020s and replaced by autonomous systems. The first boat delivered under this contract was the optionally-manned RNMB Hazard, which took part in Exercise Unmanned Warrior 16. She was followed by the autonomous RNMB Hussar in 2018 and RNMB Harrier in August 2020, by which time they came under Project Wilton within the First Mine Counter Measures Squadron at HMNB Clyde. RNMB Hebe, which arrived in 2021, is longer - instead of - to accommodate a Portable Operations Centre Afloat that allows her to control Harrier and Hazard while also co-ordinating autonomous operations. In April 2022 a further contract was awarded to AEUK to supply nine SeaCat UUVs as part of the MHC project. SeaCat can be deployed from a variety of platforms down to the size of the Sea-class workboat. Following on the Prime Minister's announcement in late 2020 of enhanced funding for the Ministry of Defence, Jeremy Quin, Minister of State for Defence Procurement, indicated on 30 November 2020, in response to a parliamentary question, that the envisaged Type 32 frigate would, in part, replace the current mine countermeasures ships and act as a "mothership" for the Navy's future unmanned mine countermeasures capabilities, as well as serving as a platform for anti-submarine warfare. Specifically, he said "... it is envisioned that Type 32 will be a platform for autonomous systems, adding to the Navy's capabilities for missions such as anti-submarine warfare and mine countermeasures". Type 32, as well as other platforms, could potentially carry a new autonomous system, which itself was announced on 26 November 2020 as being acquired through a joint production contract with France. This system employs three sets of equipment with each set comprising a portable operation centre, an autonomous surface vessel, towed sonar and a mine neutralization system. In 2023, as part of the MHC program, a commercial vessel, the former offshore support vessel MV Island Crown, was acquired for the Royal Fleet Auxiliary to act as a trials platform to further develop the concept for using motherships to support autonomous mine hunting systems. The new vessel, named RFA Stirling Castle, was to be based at the Clyde naval base. The ship was purchased for 40 million pounds and arrived at HMNB Devonport for a quick conversion to the role in January 2023, though she was subsequently transferred to the Royal Navy from the RFA due to the RFA's acute crewing problems. In due course up to three additional ships may be acquired for the mine countermeasures command and support role. As of November 2025, specifics await funding decisions associated with the SDR. Future amphibious capability The 2021 defence white paper outlined a proposal related to the composition of the Royal Navy's future amphibious capability. It was subsequently indicated that Navy's Albion-class assault ships (since removed from service), as well as the Royal Fleet Auxiliary's Bay-class landing ships and RFA Argus, would be replaced by a new class of up to six Multi Role Support/Strike Ships (MRSS). These vessels superseded an earlier plan, announced by the former Secretary of State for Defence Gavin Williamson in February 2019, that the Royal Navy would purchase two commercial ships and develop them into Littoral Strike Ships. The new MRSS vessels were envisaged as having the utility to transport and deliver troops, vehicles, equipment and supplies from anywhere in the world in support of amphibious warfare and littoral manoeuvre. They were envisaged as incorporating a "mix of ship-to-shore offloading and logistics capabilities allow support to naval operations through landing craft, boat operations, multi-spot aviation and replenishment at sea". However, that idea was subsequently dropped and in May 2024, the defence secretary, Grant Shapps, stated that the U.K. would build its vessels independently with three MRSS vessels to be built initially together with a plan for up to three additional ships. The 2021 white paper had announced that, in the interim, one of the three Bay-class vessels would be converted to a Littoral Strike Ship (LSS) and fitted with permanent hangars as well as incorporating other upgrades. All of these plans notwithstanding, in 2025 Argus was effectively laid up and deemed unsafe to sail. She was subsequently confirmed for scrapping. In 2023 it was reported that the Royal Navy and Marines were seeking a replacement for the LCVP Mk 5 landing craft with the objective of securing service entry by 2027. The new Commando Insertion Craft were to have a low signature and be able to carry a strike team and small vehicle over a distance of 150 miles at a speed of 25 knots. A production contract was reportedly envisaged by 2025. Multi Role Ocean Surveillance ship The 2021 defence white paper announced an intent to acquire a Multi-Role Ocean Surveillance ship (MROSS). The ship was planned to enter service in 2024 and was planned to be "fitted with advanced sensors and to carry a number of remotely operated and autonomous undersea drones to collect data to help protect our people and way of life with operations in UK and international waters". It was envisaged as necessary to protect undersea cable links to the UK. In November 2022, the Ministry of Defence announced that the programme would be accelerated using funds gained through the cancellation of the National Flagship, a vessel which was to be used by the monarch and government officials to promote UK interests abroad. The MOD also confirmed that the first MROSS vessel would enter service with the Royal Fleet Auxiliary in 2023. In February 2023, the first vessel for this role - MV Topaz Tangaroa - was acquired. She was purchased for some 70 million pounds and converted to act as a mothership for autonomous systems and with military communications and light defensive armament added. She entered service as in October 2023. A second MROS ship is envisaged, which may be a new build vessel and, as of 2023, is in the concept stage. Unmanned Surface Vessels In recent years the Royal Navy has examined varied options relation to the deployment and development of unmanned surface vessels. This has included the Maritime Autonomy Surface Testbed (MAST) 13 programs, a collaboration between Defence Science and Technology Laboratory (Dstl) and L3Harris Technologies employing the autonomous surface vessel Madfox. Other programs have focused on the development of autonomous minehunting capabilities to replace the Royal Navy's crewed mine countermeasures vessels. Project CABOT is another program aiming to employ autonomous vessels for anti-submarine operations in the North Atlantic. An ASW-capable Uncrewed Surface Vessel (USV) (the Type 92 'Sloop') is envisaged to complement the Royal Navy's manned surface vessels and submarines. How Project CABOT might be prioritized awaits the outcome of the 2025 defence policy review. Unmanned Submarines The Fleet Experimentation Squadron, within the Disruptive Capabilities and Technologies Office, operates the vessels and systems related to the trialing of high technology military capabilities. In 2025, XV Excalibur, an Extra Large Uncrewed Submarine (XLUUV), was christened to develop the Navy's understanding of operating large uncrewed vessels underwater. An XLUUV (Type 93 'Chariot') is also envisaged under Project CABOT to possibly complement other platforms in constructing an anti-submarine barrier in the North Atlantic. Integrating XLUUV capabilities into Project CABOT also awaits the outcome of the 2025 defence policy review. The 2017 National Shipbuilding Strategy confirm this, noting that the Fleet Solid Support ships would be subjected to an international competition and be delivered by the mid-2020s. However, late in 2019 this competition was stopped in the face of criticism that the competition permitted the potential construction of the ships outside the UK. The competition was anticipated as likely to be restarted with revised terms of reference. On 21 October 2020, it was indicated that the competition for the FSS will be restarted in Spring 2021, covering three ships and it will be an international competition but the team must be a led by a British company. The 2021 defence white paper confirmed that three FSSS would be built. In May 2021 the competition to build the ships was relaunched with the aim of taking a decision within two years. In July 2022, Rear-Admiral Paul Marshall, the Senior Responsible Officer for the Fleet Solid Support ship project, told the House of Commons Select Defence Committee that the first ship was envisaged for service entry in 2028 with the third entering service by 2032. However, subsequently the Ministry of Defence indicated that the first ship would in fact not be operational until 2031. The manufacturing contract, with a value of 1.6 billion pounds, was signed in January 2023. A parliamentary reply on 21 March 2016 noted that "The consideration of options to deliver the capabilities provided by RFA Diligence and RFA Argus remains ongoing". An August 2016 notice stated that Diligence was placed up for sale, and that the MOD was considering options for a replacement. The 2021 defence white paper was silent on a specific replacement for either vessel, essentially confirming that the enhanced aviation capabilities eventually envisaged as being provided by the mooted Multi-Role Support Ships (MRSS), would be the de facto replacement for Argus though the first MRSS might not actually enter service until the 2030s. In 2022, it was initially decided that Argus would in fact be extended in service "beyond 2030". However, by 2025 she was laid-up and deemed unsafe to sail and then confirmed for scrapping. In addition to its existing capabilities, the Royal Fleet Auxiliary has also assumed responsibility for the new MROSS capability, with a vessel purchased for that purpose and named RFA Proteus. ==Submarines==

Astute-class nuclear attack submarine In 1997 the MOD signed a contract with GEC-Marconi (now BAE Systems Submarine Solutions) to deliver a new class of nuclear powered attack submarines to the Royal Navy. This class was intended to replace the five remaining boats of the ageing , as well as the oldest two boats of the . However delays led to the construction of only seven Astute-class, thereby replacing only the Trafalgar-class de facto. The first-in-class was laid down in January 2001 and commissioned into the fleet in August 2010, followed by her sisters (2013), (2016), (2020), (2022) and (2025). As of September 2025, six of the boats have been commissioned and one remains under construction. The entry into service of the seventh boat had been planned for 2026, On 18 July 2016 the House of Commons voted 472 for and 117 against to proceed to build the new submarines. On 21 October 2016, the MoD announced that the first of the four planned boats would be named , with the name also attached to the class. Construction of Dreadnought had commenced by 2017. On 6 December 2018, the second boat of this class was named as HMS Valiant. The final two boats of the class have been named HM Submarines Warspite and King George VI. SSN-AUKUS Prior to 2023, the plan for a Maritime Underwater Future Capability (MUFC), that is, a successor to the Astute-class SSN, was known the SSN (R) program. MUFC was also known as the 'Astute Replacement Nuclear Submarine (SSN (R))'. In September 2021, a £170 million contract was awarded to BAE Systems and Rolls-Royce for initial design work on the submarines. In 2023, an agreement was reached by the American, British and Australian Governments to jointly develop a new attack submarine that is to be an evolution from SSN (R). The program will be a joint British-Australian-American project and will involve the construction of a new class of submarine for both the Royal Navy and the Royal Australian Navy. According to the Joint Leaders Statement, "Beginning in 2023, Australian military and civilian personnel will embed with the U.S. Navy, the Royal Navy, and in the United States and United Kingdom submarine industrial bases to accelerate the training of Australian personnel. The United States plans to increase SSN port visits to Australia beginning in 2023, with Australian sailors joining U.S. crews for training and development; the United Kingdom will increase visits to Australia beginning in 2026. ... In the late 2030s, the United Kingdom will deliver its first SSN-AUKUS to the Royal Navy. Australia will deliver the first SSN-AUKUS built in Australia to the Royal Australian Navy in the early 2040s". The program is to benefit from American technology transfers that will support the construction of the AUKUS submarines. In June 2025, the newly elected Labour Government announced that it would aim to acquire up to 12 SSN-AUKUS vessels to replace the Astute-class, aiming to establish a construction "drum beat" in the 2040s/2050s that would see one new submarine enter service every 18 months. Some analysis suggested that in the absence of a significant expansion of U.K. submarine-building capacity, this objective was too optimistic and unlikely to be realized. ==Aircraft==

Fixed-wing aircraft The Invincible class, because of its small size, had only a limited capacity and was only capable of operating STOVL aircraft, firstly the Sea Harrier and subsequently the Harrier GR7/GR9. In 2006 the Sea Harrier was withdrawn from service. This saw the front line Sea Harrier squadron of the Fleet Air Arm converting to the Harrier GR9, as part of the evolution of the Joint Force Harrier concept. The Harrier's replacement in both the RAF and the FAA is the American-designed and built F-35 Lightning II Joint Combat Aircraft. The F-35 is a significant improvement over the Harrier, in terms of speed, range and weapon load. The UK had plans to order 138 F-35Bs for the FAA and RAF. The financial crisis led to the decision taken in the 2010 SDSR to immediately withdraw the Harrier GR9 force in late 2010 along with HMS Ark Royal, to reduce the total number of F-35s planned for purchase by the UK, and to purchase the F-35C CATOBAR version rather than the STOVL F-35B. By May 2012, the government had decided to purchase the more expensive and less-capable short-take off version, the F-35B instead. In September 2013, it was announced that the second JSF squadron would be the Fleet Air Arm's 809 NAS. Then Chancellor of the Exchequer, George Osborne, announced on 22 November 2015 that the UK will have 24 F-35Bs on its two new carriers by 2023. While the 2015 SDSR declared that the United Kingdom would buy 138 F-35s over the life of the programme, the 2021 defence white paper sharply reduced that total to "beyond 48". Subsequently, the First Sea Lord indicated that the new envisaged number was to be 60 aircraft initially and "then maybe more", up to a maximum of around 80 to hopefully equip four "deployable squadrons". Overall, 47 Tranche 1 aircraft were in service as of March 2026. On 20 May 2016, it had been reported that the UK would field four frontline squadrons as part of its Lightning Force; in addition to 809 NAS, plus another Fleet Air Arm squadron, four Royal Air Force units (617 Sqn plus another operational squadron, 207 Sqn as the OCU, and 17(R) Squadron as the Operational Evaluation Unit) were also formed. The UK is committed to improving its F-35Bs to Block 4 standard. In 2016 it had been planned that 809 NAS would stand up in April 2023. However, by 2021 it was no longer clear that this objective would be met and a specific date for 809 NAS to stand up had yet to be confirmed. In early 2022, one analysis suggested that 809 Squadron might not stand up before 2026 and that a third frontline F-35 squadron might not be active before 2030. In September 2022, it was reported that 809 Squadron would in fact formally stand up in 2023 but that it would not be considered "deployable" for a further two years thereafter. No. 809 Squadron formally stood-up in December 2023. In 2022, U.K. Defence Secretary Ben Wallace reported that the RAF and Royal Navy faced a considerable challenge in providing even the existing modest F-35B fleet with qualified pilots. As of late 2022 there were only 30 qualified British pilots (plus three exchange pilots from the United States and Australia) for the F-35. The average wait time for RAF trainee Typhoon and F-35 pilots, after completing the Military Flying Training System, was approximately 11 and 12 months respectively. A further gap of 68 weeks existed between completing Basic Flying Training and beginning Advanced Fast Jet Training. The resulting pilot shortage was a factor in being able to stand up the first Fleet Air Arm Squadron (809 Squadron) on a timely basis. In February 2023, the Chief of the Air Staff, Air Chief Marshal Sir Mike Wigston, stated that the number of UK F-35 pilots had grown to 34, with a further 7 to complete training by August 2023. However, in 2025 the National Audit Office (NAO) reported that a consistent shortage of pilots remained, along with other shortages including of F-35 engineers. In April 2022, the Deputy Chief of Defence Staff, Air Marshal Richard Knighton, told the House of Commons Defence Select Committee that the MoD was in discussions to purchase a second tranche of 26 F-35B fighters. Nevertheless, subsequent reports suggested that this second tranche order would only be completed in 2033. Plans for frontline F-35B squadrons had been modified and now envisaged a total of three squadrons (rather than four) each deploying 12-16 aircraft. In surge conditions 24 F-35s might be embarked on the carrier but a routine deployment would likely involve 12 aircraft. At the 2025 NATO Summit at The Hague, Prime Minister Keir Starmer announced that the RAF would acquire twelve nuclear capable F-35A fighter jets. It is planned that the U.K's pending Tranche 2 order for F-35 aircraft will now comprise another 15 F-35Bs (in addition to 47 already in service) and 12 non-carrier capable F-35As. While not impacting the planned overall numbers of F-35 aircraft in the RAF/Fleet Air Arm inventory, the switch away from an exclusive F-35B fleet will, to some extent, reduce overall numbers of fighter aircraft available for carrier operations. Helicopters The 2010 Strategic Defence and Security Review saw the Fleet Air Arm transition to operate two types of helicopter – the AW101 Merlin and the AW159 Wildcat. These replaced the aging fleet of Westland Sea Kings and Westland Lynxes. There are 30 Merlin HM.2 helicopters in service. The future AEW capability of the FAA is the "Crowsnest" programme, is set to replace the Sea King ASaC.7 which retired in September 2018. All 30 of the Royal Navy's HM.2 Merlins will be equipped to carry the Crowsnest system, though a maximum of 10 could be fitted with it at any one time. As part of the process of the system reaching initial operating capability, Crowsnest was deployed with the Royal Navy's carrier task group in 2021. However, the system experienced operating challenges. Initial operating capability of the system was achieved in July 2023 with full operating capability declared in early 2025. Despite the original intent to have up to 10 Merlin helicopters deploy the Crowsnest system, it has been reported that initially only five Merlins will be equipped with Crowsnest, three of these being normally assigned to the "high readiness" aircraft carrier. Problems with Merlin/Crowsnest have caused the Royal Navy to look for a replacement. the system had a planned retirement date of 2029. In 2021, the UK's Defence and Security Accelerator (DASA) announced that options would be examined and might draw on the already existing Project Vixen (see below), researching the utility of a naval unmanned system that could encompass strike, airborne surveillance, air-to-air refueling and electronic warfare. If implemented, the replacement of Merlin/Crowsnest by another system would permit all Merlin helicopters to focus on ASW operations for the remainder of their service lives. , the out of service date for the HM.2s was envisaged as 2029 while the HC.4s were scheduled to retire by 2030. The 2021 defence white paper did not reference a Merlin replacement. However, it was subsequently indicated that the out of service date for both the HM.2s and the HC.4s had been extended to 2040. Remote Piloted Air Systems Following trials with the rail-launched ScanEagle it started operational flights of leased ScanEagles in January 2014 watching for swarm attacks on HMS Somerset and RFA Cardigan Bay in the Persian Gulf. This was expanded in November 2014, when 700X NAS was formed to serve as both the parent unit for ship based ScanEagle flights, and as the evaluation unit for any future RPAS systems that the Royal Navy elects to try. ScanEagle was withdrawn in 2017 and replaced by the RQ-20A Puma shoulder-launched UAV on board. The optionally-manned PZL-Świdnik SW-4 Solo completed trials with the RN in 2015 as part of the UK's RWUAS (Rotary Wing Unmanned Air System) Capability Concept Demonstrator (CCD) programme. In 2022, a £60 million four-year contract was awarded to Leonardo Helicopters to design and develop an uncrewed helicopter, similar to the SW-4 Solo. A three-tonne demonstrator was envisaged with anti-submarine capabilities. As of 2023, it was reported that the technology demonstrator would conduct an initial flight in 2025. A final design for the technology demonstrator was revealed in January 2025, named Proteus. It features a modular payload which can be swapped out to meet different mission requirements. In early 2023, the Schiebel S-100 Camcopter was selected to operate in an intelligence-gathering, surveillance and reconnaissance role with the Royal Navy. Named Peregrine in Royal Navy service, it began trials on HMS Lancaster in the Persian Gulf in mid-2024. The Royal Navy has also utilised 3-D printed unmanned aircraft in its operations. The Royal Navy has planned for two future UAS: The Flexible Deployable UAS (FDUAS) and Joint Mini UAS (JMUAS) programs. FDUAS is seen as a "Sea Eagle (Scan Eagle) Plus" while JMUAS is a UAS for the Royal Marines. In November 2019, 700 NAS tested two new UAS, namely, the AeroVironment RQ-20 Puma and the AeroVironment Wasp III. In 2020 NavyX tested a heavy quadcopter from Malloy Aeronautics, with the head engineer of Malloy stating that the aspiration was to autonomously deploy 180 kg payloads from a Royal Navy vessel over ranges of 20 km with their T400 quadcopter. Payloads could include people, torpedoes and fixed-wing drones. In March 2021, Project Vixen was revealed to the public as a programme to examine the use of fixed-wing UAVs from the Queen Elizabeth-class aircraft carriers in roles such as surveillance, strike, electronic warfare and air-to-air refueling. During the same month, it was also revealed that the MOD was seeking electromagnetic catapults and arrestor cables capable of launching large fixed-wing UAVs from the aircraft carriers within threefive years. During the WESTLANT 23 deployment to the US, HMS Prince of Wales is planned to trial the General Atomics Mojave, a short take-off and landing (STOL) medium-altitude long-endurance (MALE) drone to examine the feasibility of operating large fixed-wing drones for armed surveillance and other roles from carriers. Before leaving European waters, Prince of Wales conducted STOL trials with a WAS HCMC twin-engine heavy-lift RPAS to embark a dummy payload of naval memorabilia before returning to the UK with a fuel sample for laboratory testing, demonstrating the first steps in obtaining fixed-wing cargo capability for the Queen Elizabeth-class carriers. ==Royal Marines==

Outlander quad bike in 2020 The Royal Marines have been downsized and restructured in recent years, while the Navy's Albion-class assault ships were withdrawn from service in 2024/25 significantly impacting the U.K.'s power projection capabilities. Under the terms of the Government's SDR while the importance of the Royal Marines was confirmed, some analysis suggests that it remains uncertain whether the U.K. will have sufficient specialized amphibious capability in the future to generate adequate forces for projecting power ashore in either high or medium threat scenarios. Current objectives stress the need to form Littoral Response Groups (LRGs) able to provide "scalable capabilities" in different threat environments. However, the ability to do so will be dependent on the numbers of future platforms (the "Multi-Role Support/Strike Ships") acquired and on the specific capabilities of future Royal Marine landing/insertion craft. As of 2025, two future amphibious craft are envisaged for the Royal Marines: the Commando Insertion Craft (CIC) to deliver vehicles, troops and specialist equipment (while also carrying ISR capabilities); and, a Commando Utility Craft (CUC), which may incorporate uncrewed systems or containerised strike capabilities. Specifics as to the types and numbers of ships/craft acquired await funding decisions associated with the SDR. == Weapons ==

anti-ship missile on board HMS Prince of Wales (R09). • Sea Ceptor (formerly CAMM(M) or FLAADS) is a short-range air-defence missile to replace Sea Wolf on Type 23 frigates from 2016 and to be incrementally added to the armament of the Type 45 destroyers from 2026. • Sea Viper, used by the Type 45 destroyers, has undergone trials using its SAMPSON radar to track ballistic missiles, and work is ongoing to develop its Aster missiles to counter ballistic missiles. The UK is also considering upgrading its Type 45 Destroyers with the Aster 30 Block 1NT missile. Initially reported deployed with helicopters of the Royal Navy's carrier strike group in 2021. However, operating challenges were reported in 2023 as "ongoing" and full operating capability for Sea Venom was delayed until 2026. Initial operating capability with the Royal Navy was declared in October 2025. • The SPEAR 3 missile is a multi-role networked anti-ship and land-attack missile based on the Brimstone anti-tank missile with the JSOW-ER turbojet to extend the range to over 120 km. Four Spear 3 can fit in two internal weapons bay of an F-35B, MBDA are also looking at ship launch for members of the Brimstone family, including a quick-firing, anti-swarm 'Sea Spear'. In November 2021, Defence Procurement Minister Jeremy Quin suggested that full operating capability for SPEAR-3 on F-35 might occur in around 2028. • The FC/ASW (Future Cruise/Anti Ship Weapon) is a future anti-ship cruise missile planned for the Royal Navy and the French Navy. MBDA has presented Perseus, a supersonic multi-role cruise missile concept study which was unveiled at the Paris 2011 Air Show. In the 2016 UK-France Security Summit, the two parties pledged to work on a "joint concept phase for the Future Cruise/Anti-Ship Weapon (FC/ASW) programme to identify solutions for replacement of the Scalp/Storm Shadow missiles, for both countries, Harpoon for the UK and Exocet for France." In 2021, Jeremy Quin indicated that the plan was to equip the Type 26-class frigates with the missile from 2028. In October 2021 it was reported that the project had been put "on hold", at least temporarily, by France in response to the UK role in Australia's decision to cancel the acquisition of French-designed conventional submarines. Then in November the First Sea Lord, Admiral Tony Radakin, told the House of Commons Select Defence Committee that options for FC/ASW were still "being looked at" including potential hypersonic weapons. This might in fact delay the introduction of these weapons until the 2030s. The possible candidates for the requirement were the Harpoon Block II+, LRASM, Naval Strike Missile, RBS15 Mk4, Exocet Block 3C, Gabriel V missile, C-star, Type 90 Ship-to-Ship Missile or Hsiung Feng III. A contract notice was issued on 22 August 2019 for an "Interim Surface to Surface Guided Weapon System (I-SSGW)", requesting for an over-the-horizon anti ship capability and a terrain-following precision land attack capability. The land attack requirement had been likely to disqualify the Harpoon, Exocet and C-Star from the competition. However, in November 2021 the First Sea Lord, Admiral Tony Radakin, told the House of Commons Select Defence Committee that the program "had been paused" and seemed likely to be cancelled. Even so, in July 2022 Defence Secretary Ben Wallace indicated that the project might be resurrected yet again. In November 2022, the Naval Strike Missile was purchased to be fitted to 11 Type 45 destroyers and Type 23 frigates. Initial delivery of the first systems was anticipated by the end of 2023. In December 2023, HMS Somerset became the first Royal Navy warship to be equipped with the missile. • The British Government announced on 5 January 2017 that it had awarded a £30 million contract to UK consortium 'Dragonfire' to develop a directed energy weapon technology demonstrator. Their intention is to have a working prototype ready by the end of the decade and potentially have vessels equipped with directed energy weapons by the mid-2020s. In July 2022, the system began a series of trials to prove the accuracy and power of the weapon. In April 2024, Defence Secretary Grant Shapps stated that the U.K. aimed to deploy Dragonfire on Royal Navy warships by 2027 - five years earlier than previously planned. • In July 2019, the UK issued a Prior Information Notice for Directed Energy Weapon (DEW) demonstrators. This differs from the above Dragonfire as it combines multiple laser beams to produce a weapon more powerful than its predecessors and resistant to the most challenging environmental conditions. == Navigation and communication ==

• In January 2016, it was announced that a £44m Navigation Radar Programme would see "more than 60 Royal Navy ships, submarines and shore facilities" fitted with state-of-the-art navigation radars, with contracts awarded to Lockheed Martin Integrated Systems UK and Kelvin Hughes. • The MoD is reportedly investing heavily in development of quantum compasses which could potentially transcend the need for GPS as a means of navigation, providing a self-contained and interference-proof alternative. Deployment of this technology is often discussed with regard to the Royal Navy's submarine fleet, allowing vessels to navigate without outside assistance and therefore remain submerged for extended lengths of time. • In December 2018, it was announced that a £23m agreement to provide Royal Navy and Royal Fleet Auxiliary ships with new radios had been signed. The radios will be installed on 39 ships in total, including 13 Type 23 Frigates, 4 survey and ice patrol vessels, 13 minehunters and 9 RFA supply ships and will be used to communicate with other ships, ports and aircraft during operations. They will replace numerous older radios and as more modern pieces of equipment, they are easier to use/maintain, can be updated via software and operated remotely. Under the contract, Thales will develop, fit and support a V/UHF radio solution which includes the acquisition of around 300 Rohde & Schwarz radios. The first radio will enter service on a Type 23 Frigate in 2020, with all radios due to be delivered and installed by the end of 2023. ==See also==
