A Class (1904) SS
class of Submarines were a development of the previous Holland
Class (1901) SS boats, and were designed as coastal submarines. They
were the first all British submarine design.
They were built in two broadly similar groups, with the second group being slightly larger and with more powerful engines. The last of the Class A13 was the first British submarine to carry a diesel engine, which was much safer than previous petrol engines.
Like the Holland's they had low buoyancy reserves.
They were considered an unlucky class as only five out of the 13 built escaped accidents.
However they had considerable sea-handling improvements and vastly extended experience in dived operations.
During WW1 the survivors were only used for training.
