The conning tower hatch of submarine AE2 was opened last month

Last month, the conning tower hatch of Royal Australian Navy submarine AE2 was opened. High definition cameras and imaging sonar were inserted through the opening and an ROV (Remotely Operated Vehicle) surveyed inside the submarine. The AE2 was scuttled in deep water in the Sea of Marmara on 30th April 1915.
