The British H class submarines were Holland 602 type submarines used by the Royal Navy. The submarines constructed for the British Royal Navy between 1915 and 1919 were designed and built in response to German boats which mined British waters and sank coastal shipping with ease due to their small size. The H-Class was therefore created to perform similar operations in German waters, and to attack German submarines operating in British waters. Despite their cramped size and lack of a deck gun, the class became enormously popular amongst submariners, and saw action all around the British Isles, some being transferred as far as the Adriatic. Due to the later arrival of most of the class, they were unable to have a massive impact, only achieving two victories (the German submarines U-51 and UB-52) for the loss of four of their own number in the First World War. Post war many were retained in the Royal Navy for training purposes, and four more were lost in wrecks during the 1920s.
