Astraea-class cruiser
The ''Astraea'' class was an eight ship class of protected cruisers built for the Royal Navy during the 1890s. The ships served on a number of foreign stations during their careers, particularly in the waters of the Indian and Pacific Oceans, and around the Cape of Good Hope. Already obsolete by the outbreak of the First World War, most continued to see service in a variety of roles, though rarely in a front line capacity. By the end of the war the majority were being used as training or depot ships, and they were soon sold out of the service and scrapped. However one ship, , was bought by the Marine Society and used as a training ship until 1940.
==Design and construction==
The eight ships were ordered under the provisions of the 1889 Naval Defence Act as an improved design of the preceding s. They were to displace 1000 tons more than the ''Apollo''s, and were to have improved sea-keeping abilities, and heavier and better placed armament.〔 The result was a design with a full length deck that gave a higher freeboard amidships, and placed the main armament higher on the superstructure. Though this made them drier ships, the design was criticised for being a larger and more expensive development of the ''Apollo''s, but without offering any substantial increase in armament, speed or endurance.〔 The increased weight did however make them more seaworthy, and the design provided the basis for the development of future protected cruisers.〔 The ships were built at several of the principal navy dockyards: three at Devonport, two at Pembroke, and one each at Sheerness, Chatham and Portsmouth.〔
