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 naval heroes.

This book shows the true depths of their achievements. These were men whose warrior exploits stand alongside those of any other nations. But they have been largely unrecognised, save for those submarines.

The Submarine Six also examines whether two more of its men deserve futher honor. Teddy Sheean, tenacious gunner from Tasmania, fought to the end in HMAS Armidale. Robert Rankin commanded HMAS Yarra against fearful odds, dying in defence of his convoy, attacked by overwhelming Japanese forces. Are they also VC candidates?
