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 May 2024, there are 66 commissioned ships in the Royal Navy.

Of the commissioned vessels, nineteen are major surface combatants (two aircraft carriers, six guided missile destroyers, nine frigates and two amphibious transport docks) and ten are nuclear-powered submarines (four ballistic missile submarines and six fleet submarines). In addition the Navy possesses seven mine countermeasures vessels, twenty-six patrol vessels, two survey vessels, one icebreaker and one historic warship, HMS Victory. The total displacement of the Royal Navy's commissioned ships is approximately 411,400 tonnes.

The Royal Navy also includes a number of smaller non-commissioned assets. The naval training vessels HMS Brecon (M29) and Hindostan can be found based at the Royal Navy stone frigates HMS Raleigh (shore establishment) 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, 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 NavyX, a unit of the Royal Navy dedicated to developing, testing and accelerating the use of new high 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 79 vessels with a total displacement in excess of 752,400 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. A general-purpose frigate and vessels belonging to the navy's 9th Mine Counter-Measures Squadron are forward-deployed there. Two fast patrol boats, together with a forward-deployed River-class offshore patrol vessel, normally form part of the Gibraltar Squadron and are permanently based there. Four other River-class vessels are also forward-deployed: one in the Falkland Islands, one in the Caribbean and two in the Indo-Pacific region. Additionally, the United Kingdom maintains a Joint Logistics Support Base in Duqm, Oman which hosts the Littoral Response Group (South) composed of two ships from the Royal Fleet Auxiliary, though also supported by Royal Navy assets as may be available and required.

All ships and submarines currently in commission with the Royal Navy were built in the United Kingdom, with the exceptions of icebreaker HMS Protector (A173) which was built in Norway and survey vessel HMS Magpie (H130) which was substantially built in Ireland. All commissioned vessels of the Royal Navy bear the ship prefix "HMS", for His Majesty's Ship or His Majesty's Submarine.
