| Notes on class | The A-class submarines developed from the T-class and were designed for operations in the far east. Unfortunately arrived too late for use in the war. This new class had a much greater operational range then the T-class and increased surface speed. Also they had an all-welded hull. Submarines of this class that have a detailed wartime history added are shown in bold in the list below. Only two of these class were commissioned before the Second World War ended. |
