SYDNEY -- The wartime midget submarine discovered off the beaches of Sydney is to be left on the ocean floor and is expected to become a permanent tomb for the two crewmen killed inside the vessel after their attack on Sydney Harbour in 1942.
Australian government officials have confirmed that the sub will probably never be raised for various reasons, including technical difficulties. The vessel's discovery last month by amateur divers ended a 64-year mystery about its whereabouts.
The officials also confirmed it is "highly unlikely" any attempt will be made to retrieve the remains of the two young submariners -- known in wartime Japan as "hero gods."
