The Royal Australian Submarine HMAS Dechaineux has just limped back to port after a catastrophic flood came within seconds of sinking her and her 60 crew members. Suddenly, the navy has a crisis on its hands. How will it deal with this near-disaster? What will it mean for the new Collins Class fleet? How will the navy explain it publicly? And what about the crew who have been traumatised by this near-death experience? In Episode 4 we investigate the human, strategic and public relations fallout from The Flood.
