List of active Royal Navy ships

The Royal Navy is the principal naval warfare service branch of the British Armed Forces. Its assets include both commissioned warships and non-commissioned vessels. As of December 2025, there are 63 commissioned ships, including auxiliary ships, in the Royal Navy. However, increasingly many of the Royal Navy's ships are old and some have proven to be minimally seaworthy. The situation has been described in the media and by some politicians as a national embarrassment. According to the Conservative MP Ben Obese-Jecty, the Royal Navy has effectively run out of ships. According to Gwyn Jenkins, the First Sea Lord and Chief of the Naval Staff, the Royal Navy will not be ready for an armed conflict until 2030. Of the commissioned vessels, fifteen are major surface combatants (two aircraft carriers, six guided missile destroyers and seven frigates) and ten are nuclear-powered submarines (four ballistic missile submarines and six fleet submarines). In addition the Navy possesses eight mine countermeasures vessels, twenty-six patrol vessels, two survey vessels, one icebreaker and one historic warship, Victory. The total displacement of the Royal Navy's commissioned and active ships is approximately 401,600 tonnes. The Royal Navy also includes several smaller non-commissioned assets. The naval training vessels Brecon and Hindostan can be found based at the Royal Navy stone frigates HMS Raleigh and the Britannia Royal Naval College, respectively. Non-commissioned Sea-class workboats, procured under Project Vahana, are operated by the Royal Navy in various support, survey and training roles, replacing previous P1000 Class Picket Boat vessels. This class of vessel also incorporates an autonomous minehunting variant (known as the Arcims-class), while another autonomous vessel, Madfox, is employed in varied roles including as a testbed for autonomous combat operations. Madfox and other experimental vessels, including XV Patrick Blackett and APAC-24 (a crewless Pacific 24 rigid-hulled inflatable boat), are operated by the Fleet Experimentation Squadron within the Disruptive Capabilities and Technologies Office. As of 2025, XV Excalibur, an Extra-Large Uncrewed Underwater Vehicle (XLUUV), was also operated by the Squadron while other autonomous surface vessels, for minehunting and other roles, were in service and in the process of procurement from Thales Group and Kraken Technologies. Besides the Royal Navy, the Royal Fleet Auxiliary (RFA) and the Royal Marines operate their own flotillas of vessels which complement the assets of the Royal Navy. These vessels are not included in this list or the above figures. Nevertheless, combined, the Royal Navy and RFA have 72 vessels with a total displacement of about 645,600 tonnes, with the principal landing craft of the Royal Marines having an additional combined displacement of about 2,200 tonnes. As a supporting contingent of His Majesty's Naval Service, the civilian Marine Services operate nearly 100 auxiliary ships (including coastal logistics, tugs and research vessels) in support of Royal Navy and Royal Fleet Auxiliary operations. In the United Kingdom, the Royal Navy operates three main bases where commissioned ships are based: HMNB Portsmouth, HMNB Devonport and HMNB Clyde. A number of commissioned vessels, belonging to the University Royal Naval Units (URNU), are stationed at various other locations around the United Kingdom. The Royal Navy's principal overseas base is HMS Jufair in Bahrain. However, as of early 2026 there were no crewed vessels permanently based there. Two fast patrol boats normally form part of the Gibraltar Squadron and are permanently based there. Some River-class offshore patrol vessels are also forward-deployed: including in the Falkland Islands, in the Indo-Pacific region and, somewhat more intermittently, in the Caribbean or out of Gibraltar. Additionally, the United Kingdom maintains a Joint Logistics Support Base in Duqm, Oman. All ships and submarines currently in commission with the Royal Navy were built in the United Kingdom, with the exceptions of icebreaker Protector which was built in Norway, the survey vessel Magpie which was substantially built in Ireland, and the specialist mine countermeasures vessel HMS Stirling Castle, a former vessel of the Royal Fleet Auxiliary originally built in Romania. All commissioned vessels of the Royal Navy bear the ship prefix "HMS", for His Majesty's Ship or His Majesty's Submarine.
