They were the first class of first-class cruisers built for the Royal Navy.Brown 1997, p. 135. Main gun armament was similar to that of the ''Orlando''s, consisting of two Mark VI breech loading guns mounted in single mounts fore and aft on the ship's centreline, and ten 6 in (152 mm) QF guns, of which six were mounted in single mounts on the ships' top deck and the remaining four mounted behind armoured casemates on the ships'

Machinery consisted of 4 three-cylinder triple expansion engines fed by six double-ended cylindrical boilers and driving two shafts. The engines generated under natural draught and with forced draught, giving a speed of with forced draught and with natural draught.
