US authorities say a debris field located in the North Atlantic leads to a conclusion that OceanGate's Titan submersible suffered a "catastrophic implosion" (a violent collapse inwards), instantly killing all five passengers on board.
The US Navy says it detected sounds "consistent with an implosion" shortly after the sub lost contact on Sunday during a descent to the Titanic wreck at 3,800m (12,467ft) below sea level - but this information was only made public on Thursday.
The loss of the deep-water vessel was finally confirmed after a huge search mission in the area off Canada's Newfoundland province.
What caused the implosion?
Titan's hull is believed to have collapsed on Sunday as a result of enormous water pressure.
