The Royal Navy currently operates three bases where commissioned ships are based; HMNB Portsmouth, HMNB Devonport and HMNB Clyde. In addition, a number of commissioned vessels belonging to the University Royal Naval Units (URNU) are stationed at various locations around the United Kingdom. The total displacement of the Royal Navy is approximately 337,000 tonnes (641,000 tonnes including the Royal Fleet Auxiliary and Royal Marines).

Besides the Royal Navy, the Royal Fleet Auxiliary and the Royal Marines operate their own flotillas of naval vessels which complement the assets of the Royal Navy, however they are not included in this list or the above figures. In addition, the naval training vessels Brecon and Cromer can be found based at the Royal Navy shore establishment HMS Raleigh and the Britannia Royal Naval College, respectively. As a supporting contingent of Her Majesty's Naval Service, the civilian Marine Services operate a large number of auxiliary ships (including coastal logistics, tugs and research vessels) in support of Royal Navy and Royal Fleet Auxiliary operations.
