New York: Marine archaeologists believe they have finally identified the resting place of HMB Endeavour, the ship James Cook commanded to Australia on his first voyage of discovery, an achievement that would solve one of the greatest maritime mysteries of all time.

The breakthrough has raised hopes the remains of the vessel will be excavated next year, in time for the 250th anniversary of Cook's arrival in Australia. The ship is historically significant to many countries - including the US, Britain, New Zealand and Australia - and its excavation could spark a battle over where the wreckage should be housed.

The Rhode Island state government claimed official ownership of the fleet of shipwrecks including Endeavour in 1999, suggesting Australian officials would have to negotiate for any remnants to be brought to Australia.

The breakthrough, to be officially announced on Friday, follows an arduous 25-year search for the historic ship off Newport, Rhode Island, on the north-eastern coast of the US.
