The US Navy detected “an acoustic anomaly consistent with an implosion” just hours after the Titan began its dive on Sunday.

The information was immediately shared with the US Coast Guard, which used it to narrow the scope of its search, an official told CBS News.

But it's not clear why this information was not made public earlier.

It's believed the implosion sound was picked by the Navy's secretive long-range sonar listening system which has its origins in the Cold War.

The Sound Surveillance System was created in the 1950s to listen for Soviet submarines in the remote depths of the Atlantic Ocean.

Precise details of current operations are classified, but a US Navy website describes them as performing “detection, localisation and tracking of submarines and the collection of acoustic and hydrographic information.” - BBC News

Tributes are flowing for the five men killed on board the Titan sub in what US officials say was a "catastrophic implosion."

The victims were Hamish Harding, 58, Shahzada Dawood, 48, and his son Suleman Dawood, 19, Paul-Henri Nargeolet, 77, and Stockton Rush, 61.

Their families have expressed "profound grief" and paid tribute to their exploration endeavoursA robotic diving vehicle found major fragments of the sub on the ocean floor about 1,600ft (480m) from the Titanic shipwreck on Thursday.

It's emerged that the US Navy also detected “an acoustic anomaly consistent with an implosion” shortly after the Titan lost contact on Sunday.

Banging sounds reported earlier this week are now thought to have come from other ships in the areaThe sombre findings end an international five-day search for the submersible which had been on an expedition to the century-old wreck.
