The submarine which caught fire approximately 100 miles off the Donegal coast earlier this week has docked at a naval base in Scotland.
The HMCS Chicatoumi will be examined by experts at Naval Base Clyde at Faslane, near Glasgow to determine what caused Tuesday's fire in which one crewman died and two others were seriously injured.
The Canadian sailor who died in hospital in Sligo on Wednesday from the effects of smoke inhalation on the stricken submarine left drifting 100 miles off the west coast following a fire five days ago received a military farewell at Dublin Airport today.
Members of the Defence Forces, the Naval Service and Canadian Naval personnel gathered at Dublin Airport for the religious and military ceremony.
The body of father-of-two, Lieutenant Chris Saunders, is being flown home to Halifax in Canada aboard a Canadian Air Force plane.
The Canadian Ambassador to the Republic, Mr Mark Moher, the Chief of Staff of the Irish Defence Forces, Lieutenant General Jim Sreenan and the flag officer commanding the Irish Naval services, Commodore Frank Lynch, attended the removal.
Two other crewmen who were also airlifted by Royal Navy Sea King helicopter to Sligo General Hospital remained there overnight.
Staff at the hospital said that the two men, one of whom had been critical, should be released within the next few days.
