The Endeavour was scuttled there by the British 244 years ago and lay forgotten for more than two centuries.
Several details on the wreck convinced archaeologists they had found Endeavour after matching structural details and the shape of the remains to those on 18th century plans of Endeavour.
“I am satisfied that this is the final resting place of one of the most important and contentious vessels in Australia’s maritime history,” Sumption said at the Maritime Museum.
“The last pieces of the puzzle had to be confirmed before I felt able to make this calxjmtzywl.
“Based on archival and archaeological evidence, I’m convinced it’s the Endeavour.
“It’s an important historical moment, as this vessel’s role in exploration, astronomy and science applies not just to Australia, but also Aotearoa New Zealand, the United Kingdom and the United States.”
Only around 15 per cent of the vessel remains and researchers are now focused on what can be done to protect and preserve it.
The museum is working closely with maritime experts in Rhode Island as well as the Australian, Rhode Island and US governments to secure the site.
Originally launched in 1764 as the Earl of Pembroke, the ship was renamed Endeavour in 1768 by Britain’s Royal Navy and prepared for a major scientific voyage to the Pacific.
