Project history: The mixed armament of the Bristol class was soon recognised as unsatisfactory, and to remedy this the 'improved Bristol class' authorised under the 1909-1910 Estimates were given a uniform armament of 8 152mm. There were also complaints about the waist guns being unworkable in a seaway, and in the new cruisers the forecastle was extended aft and a bulwark enclosed the waist guns. In addition to the forecastle gun two more were carried at the same level p&s of the bridge, giving them much better command. The Weymouths were a great improvement over the Bristols and paved the way for even better ships. Being robust and well armed they saw widespread service and were retained in the post-war Fleet.
Ship protection: protective deck with slopes was 51mm thick over machinery and 19mm over other parts.

Weymouth was damaged by torpedo from Austrian submarine U28 2.10.1918, repaired, paid off in September 1927. Yarmouth was put on sales in November 1928.
