This Class represented the final development of the original Holland Class.There was an increase in size but little else changed, still no interior bulkheads and still inferior living conditions.This Class was also the last to be equipped with petrol engines, also the first British submarines to be designed with forward hydroplanes (this only applied to the boats in Group Two of the Class).

With the introduction of the 'C' class the monopoly of submarine building by Vickers was broken with six of the class being being built by the Naval Dockyard at Chatham.

With the exception of C26, C27 and C38, which had been sent to Hong Kong in 1910, this class served in Home waters until the outbreak of the Great War (1914-1918).   They were used extensively throughout the war operating from the East coast ports or Dover.

Four of this class saw service in the Baltic, having been transported by sea to Murmansk and by barge and train to Lapvik where they were reassembled.   All these boats suffered the same fate of being scuttled, 3 to save falling into the hands of the Revolutionary Russians and 1 having run aground.
