This is the fifth fully revised edition of a book first published in 1970. This longevity is testimony to its enduring value as a reference work—indeed, "Colledge" (as it is universally known) is still the first stop for anyone wanting more information on any British warship from the fifteenth century to the present day when only the name is known. Each entry gives concise details of dimensions, armament and service dates, and its alphabetical and chronological arrangement makes it easy to track down the right ship (otherwise the Royal Navy's tradition of re—using the same names can be misleading). This edition contains more than two hundred new entries and revisions to many older entries.
