After World War I, Australia was given six ‘J’ Class submarines by Britain, but lacked the personnel and funds to maintain them. They were soon scrapped. Two submarines acquired in the late 1920s – Oxley and Otway – were decommissioned during the Great Depression.

All six boats served with distinction during the Cold War, several engaging in highly classified ‘special operations’. By the mid 1980sthe RAN’s ageing submarine fleet needed replacing.
