Ship project history: Five more light cruisers were ordered in June-July 1917, basically repeats of the Ceres class, bur with a raised 'trawler' bow to prevent spray from blanketing 'A' and 'B' guns. Stem height have increased by 1.5m at the expense of what the forecastle deck fwd from "A" gun had enough steep slope.

"C" type cruisers were created for service in the North Sea under 1915 year design and become obsolete to the beginning of 1930th, and in 1935 the decision to convert them to AA ships was accepted. Update of prototypes Coventry and Curlew has appeared successful, and during the period 1936-1940 it was planed rearm similarly remained 11 "C" type ships. However the program has been put aside, and only in 1938 works on Cairo and Calcutta have begun. Unlike first two ships they received twin 102mm mounts and only one quadruple pompom. They became operational in May and July, 1939 respectively. In the middle of the same year works on Carlisle have begun. It was planed that other ships of class will follow them but the begun of war was compelled to be limited to end of works on this ship which has become operational in 1940. Program was restarted only in 1942, when update have passed Colombo (June, 1942 - March, 1943). The arms structure on her significantly differed from others: the number of 102mm mounts was cut to three, but means of small calibre AA guns have significantly amplified. After conversion of Colombo and last Caledon the program have ultimately ended: there was no sense to spend means for obsolete ships.

Ship protection: Armoured belt protected ship at full length, its thickness was 76mm abreast machinery spaces (51mm armour on 25mm plating), 51mm (38mm armour on 13mm plating) aft and 38mm (25mm armour on 13mm plating) fore. Belt was closed by aft 25mm bulkhead near stern. It extended to main deck (and to upper deck abreast machinery). Machinery and steering gear were covered by 25mm deck.
