The Monmouth class was a ten-ship class of 10,000 ton armoured cruisers built around 1901 to 1903 for the Royal Navy and designed specifically for commerce protection. The ships were also referred to as County-class cruisers as they carried the names of British counties.

Aft port casemate guns on Berwick, illustrating the unfortunate positioning

Expected only to fight light cruisers and armed merchant ships, they were armed with fourteen 6-inch guns at a time when most British armoured cruisers also carried at least a pair of 9.2-inch guns: Four of the guns were mounted in two twin turrets at a good height, the remaining ten were installed in hull-mounted casemates, 5 on each side. The lower casemate guns were just a few feet above water, making them impossible to use in heavy seas. Sir John Fisher commented that "Sir William White designed the County class but forgot the guns." On the other hand, they were relatively fast ships for their time.

Building programme

The following table gives the build details and purchase cost of the members of the Monmouth class. Standard British practice at that time was for these costs to exclude armament and stores. The compilers of The Naval Annual revised costs quoted for British ships between the 1905 and 1906 editions. The reasons for the differences are unclear.
