I came across on less unfortunate submarines of the J-Class Submarines, the HMS J7 later knowns as HMAS J7.
She was a World War I commissioned Submarine that came into service later part of war in 1917.
During the war, she missed a lot opportunities to sink German vessels.'
After the war, six survivors of her class were transferred to the Australian Admiralty.
Prior to the transfer, a sister ship was sunk by accident its OWN navy...
While in service of Her Royal Highness's Australian Navy and eventually she was retired from service due to high maintenance and multiple failures to increase accommodations on board the ship by getting rid of some of it's tubes. She was towed from Flinders Naval Depot, Crib Point, where she had served as a reserve source of electric power, on 4 December 1929.
However year later she was dismantled and sunk as a breakwater Sandringham Yacht Club, Sandringham, Port Phillip Bay, where she surprisingly remains to this day.
Lordy, i'm surrpise the environmental people didn't get on yacht yard's ownership about this thing.
