(NEXSTAR) – A U.S. Navy acoustic system detected an ‘anomaly’ Sunday that was likely the Titan’s fatal implosion, according to a senior military official.

The Navy went back and analyzed its acoustic data after the Titan submersible was reported missing Sunday. Coast Guard officials on Thursday announced that the craft suffered a catastrophic implosion, killing all five aboard.

That anomaly was “consistent with an implosion or explosion in the general vicinity of where the TITAN submersible was operating when communications were lost,” according to a senior Navy official.

The official spoke on condition of anonymity to discuss a sensitive acoustic detection system.

The Navy passed on the information to the Coast Guard, which continued its search because the Navy did not consider the data to be definitive.

The Wall Street Journal on Thursday first reported the Navy’s involvement.

The five people on board when the ship imploded were OceanGate CEO Stockton Rush; British businessman and explorer Hamish Harding; Pakistani investor Shahzada Dawood and his 19-year-old son, Suleman; and French diver Paul-Henri Nargeolet.

On Thursday, OceanGate issued the following statement:

These men were true explorers who shared a distinct spirit of adventure, and a deep passion for exploring and protecting the world’s oceans. Our hearts are with these five souls and every member of their families during this tragic time. We grieve the loss of life and joy they brought to everyone they knew. 

This is an extremely sad time for our dedicated employees who are exhausted and grieving deeply over this loss. The entire OceanGate family is deeply grateful for the countless men and women from multiple organizations of the international community who expedited wide-ranging resources and have worked so very hard on this mission. We appreciate their commitment to finding these five explorers, and their days and nights of tireless work in support of our crew and their families. 

This is a very sad time for the entire explorer community, and for each of the family members of those lost at sea. We respectfully ask that the privacy of these families be respected during this most painful time.
