The Royal Navy has received its twenty-four Type-45 Destroyers, as commissioned in the 2015 Autumn Statement. The Vessels have been named and categorised as follows: the Prime Ministerial Class includes the HMS Duke of Wellington, the HMS Disraeli, the HMS David Lloyd-George, and the HMS David Cameron; the Royal Class includes the HMS Duke of Edinburgh, the HMS Duke of Cornwall, the HMS Duke of York, the HMS Duke of Cambridge, the HMS Duke of Kent, and the HMS Duke of Gloucester; the Classical Mythology Class includes the HMS Demeter, the HMS Diomedes, the HMS Dike, and the HMS Daedalus; the Britons Class includes the HMS Diana, the HMS Darwin, the HMS Duncan Edwards, the HMS Dixie Dean, the HMS David Davis, and the HMS Dylan Thomas; the England Class includes the HMS Derby, the HMS Durham, the HMS Dover, and the HMS Dorset.

The Prime Ministerial Class and the England Class, in addition to HMSs Diomedes and Dike, will serve an escort for the HMS Thatcher, launched last November and completed with F-35s, and which will now depart to a point of tactical advantage in order to continue airstrikes in Iraq, with the flagship Destroyer being the HMS Duke of Wellington. The Royal and Briton Classes will serve mainly on humanitarian missions, whereas HMSs Deadalus and Demeter will conduct anti-piracy operations off the Somali coast. The MoD has chosen to additionally commission the Scotland Class, which will include the HMS Dundee, and the HMS Dumfries, and both are expected to be launched in 2020, costing £1.1bn: HMS Duncan will serve as vanguard to the Falklands until this time.
