The U.S. Coast Guard has announced a scheduled press conference in Boston, Massachusetts at 3 p.m. ET. This comes following a significant development in the search for OceanGate's missing Titan submarine, with the discovery of an underwater "debris field."

According to a Coast Guard press release, the briefing aims to discuss findings from the remotely operated vehicle (ROV) of the Horizon Arctic near the Titanic wreck site.

Just five hours ago, the Coast Guard confirmed that the Horizon Arctic's ROV had successfully reached the ocean floor and commenced its search for the lost submersible.

The Titan submarine vanished on Sunday morning while carrying five individuals: Stockton Rush, the CEO of OceanGate, French mariner Paul-Henry Nargeolet, British businessman and explorer Hamish Harding, Pakistani businessman Shahzada Dawood, and his son Sulaiman Dawood.

Approximately 1 hour and 45 minutes into the dive, the Titan lost contact with its surface vessel, the Polar Prince. The incident occurred around 900 miles east of Cape Cod, Massachusetts, and approximately 400 miles southeast of St. John's in Newfoundland, Canada.

The search effort, spearheaded by the U.S. Coast Guard, involves a unified command that incorporates commercial assets, research vehicles, and military counterparts from Canada, France, and the United Kingdom.

Canadian pilots participating in the operation reported picking up repeated sounds during their search on Tuesday and Wednesday, further raising hopes for a breakthrough in locating the missing submarine.

The upcoming press conference is anticipated to provide additional insights into the progress made in the search and the significance of the underwater "debris field" discovery.

The following individuals will participate in the briefing later today:

  • Rear Adm. John Mauger, the First Coast Guard District commander
  • Capt. Jamie Frederick, the First Coast Guard District response coordinator
