Six RAN heroes for whom six Collins class submarines are named. Naval conflicts take place often far from our shores. Ships and men sometimes disappear, to leave only mystery in their wake. In the 1990s the Royal Australian Navy broke with tradition, and for the first time named six submarines after six naval heroes. This book shows the true depths of their achievements. These were men whose warrior exploits stand alongside those of any from other nations. But they have been largely unrecognised, save for those submarines.
