Ships of the Royal Navy is a naval history reference work by J. J. Colledge (1908–1997); it provides brief alphabetical dictionary-like entries on all recorded ships in commission in the Royal Navy from the 14th century, giving location of construction, date of launch, tonnage, specification and fate. The 2020 edition had over 15,000 entries going back to 1300. A similar revision of Volume 2 followed in 1989. Colledge made no more revision, dying in 1997. Ben Warlow, a retired naval officer associated with the Naval Historical Branch, took over the task of publishing a second revision of Volume 1 in 2003, reinstating some of the smaller vessels that the first revision had omitted; no second revision of Volume 2 was done at the time. A third revision of Volume 1 was published in 2006, also by Warlow. In 2010, Warlow followed with an expanded fourth revision, this time incorporating both Volume 1 and 2 containing the smaller and exotic vessels, such as requisitioned ships, e.g. Armed merchant cruisers, Merchant aircraft carriers, as well as small craft, e.g. landing craft and Admiralty-built trawlers. A fifth revision was completed in 2020, again including both volumes, by Warlow along with Steve Bush. It incorporates, for the first time, the ships of the Royal Fleet Auxiliary, a branch separate from the Royal Navy.
