After thirteen previous search missions over many years, a search using the vessel Defence minister Marise Payne stated that “this is one of the most significant discoveries in Australia’s naval maritime history.”Now that the vessel’s location is known, the museum’s focus will shift to preservation of the wreck, and understanding what happened to the AE1, and why.Subscribe and discover what’s happening at the museum Copyright © 2020 On 14 September 1914, AE1 disappeared without trace off the coast of Papua New Guinea. AE1 was the Australia’s first submarine.. Further details are available on the Submarine Institute of Australia’s website.2 Darren Brown’s meticulous research uncovered most of these documents.4 https://www.anmm.gov.au/about/media/media-releases/media/2018/09/13/05/12/ae1-survey-reportNaval Historical Society of Australia Inc. Various proposals envisaging three, nine or 12 were aired before settling on two E-class submarines for Australia—hence their names The delivery voyage was marked by technical issues, two propeller changes for After a delivery voyage that broke records, the submarines (The story of the successful landing at the expense of Australia’s first casualties in WWI has been told elsewhere. As to the lack of evidence, it must be remembered that whatever happened to AE1 probably occurred no later than 6 pm and possibly as early as 3.30 pm.

The submarine headed off to continue patrolling and was never seen again. After all, AE1’s captain, Lieutenant Commander Besant, was well known for his skill and alertness. And yet the submarine had disappeared. An expedition has returned after uncovering new clues about what happened to Australia's first submarine, HMAS AE1. This report recommends urgent PNG and Australian action to jointly declare the wreck a protected area and establish effective monitoring of the site. On completion, what looked like the outlines of hydroplanes at the bow and stern of the contact could be made out and it was decided to stop the search and inspect the contact with a drop camera. Within 30 seconds of the camera coming in range of what turned out to be the bow, The images gained from the drop camera and a third sortie by the AUV to photograph the wreck gave a good overall understanding of the wreck’s situation – it had clearly exceeded its crush depth and imploded – but why?This question was solved in April 2018, when Paul Allen, the co-founder of Microsoft, generously offered Find AE1 Ltd. the use of his specialised ship, the Research Vessel The open valve would have permitted seawater to enter the engine room, quickly making its way to the bilges and causing electrical short circuits, probably leading to a loss of propulsion and lighting. The second impact snapped off the forward hydroplane guards and broke the back of the submarine at the forward end of the keel.This analysis has been confirmed by external experts as a reasonable interpretation of the clues.
