The Search for Titan: Knocking Sounds, a Debris Field, and Breaking Developments in the Rescue Effort

Jamie Frederick, 1 Coast Guard District, speaks with the press on Wednesday, June 21, 2023 (U.S. Coast Guard).

Welcome to this week’s installment of The Intelligence Brief… as the search for a missing submersible has captured the world’s attention, this week we’ll be analyzing the rescue effort and examining 1) what we currently know about the search for Titan and 2) the company behind the missing vessel, as well as 3) what U.S. Coast Guard and those assisting it have found, and 4) potentially breaking developments in the Rescue Effort.

With all the housekeeping behind us, it’s time to turn our attention to the current situation developing with regard to the missing submersible Titan and what the U.S. Coast Guard may be planning to reveal later this afternoon about what the search effort has yielded.

Desperate Search Ensues for a Missing Submersible

Since late Sunday, the search for Titan, a missing submersible research vessel that vanished while on its way to view the wreckage of the famous sunken Titanic, has captured the world’s attention as a desperate effort to recover the lost vessel before its five-person crew loses oxygen has remained underway.

The search effort, led by the United States Coast Guard with assistance from international partners, has focused on an area approximately 900 miles off the coast of Cape Cod, Massachusetts, since the small submersible was reported lost after a Canadian research ship, the MV Polar Prince, lost contact with the craft and its crew.

Hopes that the passengers could be saved have dwindled amidst reports that the vessel’s oxygen levels would likely be incapable of supporting its crew beyond Thursday morning, despite reports in recent days of banging sounds detected by sonar devices.

As efforts continue to attempt to locate the 21-foot submersible, several questions remain about what circumstances might have led to its disappearance. So what do we currently know about the search for Titan, as well as the company behind the missing vessel, what the U.S. Coast Guard and those assisting in the effort have found, and the likelihood at this point that rescue attempts might still succeed?


On Wednesday, the U.S. Coast Guard issued an update on the search for the Titan, stating that several ships equipped with sonar and search aircraft have been deployed in the effort. These include three Canadian vessels, the CGS Ann Harvey, CGS Terry Fox, and the Glace Bay, which is equipped with medical personnel and a mobile decompression chamber.

A French Research Vessel, L’Atalante, and several other craft were also deployed to the area. Canadian Coast Guard vessels also arrived on the scene on Wednesday.

“The Canadian Coast Guard boat John Cabot, a vessel with sonar capabilities, arrived on-scene Wednesday morning along with commercial vessels Skandi Vinland and the Atlantic Merlin,” the U.S. Coast Guard said, adding that one of its own C-130 aircraft had carried a Coast Guard crew to the scene to assist in the search.

“Underwater sounds have been detected in the search area, resulting in the redirection of remotely operated vehicle (ROV) operations to explore the origin,” the Coast Guard said. “These recordings have been shared with the U.S. Navy for analysis to help guide future search efforts.”

This morning, additional ROVs were deployed to assist in the deep Atlantic search for the Titan around one of the world’s most famous ship wreckage sites.

OceanGate Expeditions

Titan is a submersible owned by the Everett, Washington-based company OceanGate Expeditions. Founded in 2009 by Stockton Rush, the company has endeavored to make deep-ocean exploration more accessible by providing submersibles for underwater expeditions, tourism to underwater shipwrecks, and also crewed vessels for both scientific and commercial projects.

Rush, who is the company’s CEO and founder, is a pilot and aerospace engineer who, by age 19, had succeeded in becoming the youngest jet transport-rated pilot.

“Our team of qualified pilots, expedition leaders, mission professionals and client-service staff ensure accountability throughout the entire mission and expedition process with a focus on safety, proactive communication and client satisfaction,” the OceanGate Expeditions website states. As of Thursday morning, the company’s site was experiencing periodic timeouts due to the attention it has received since Titan was reported missing on Sunday evening.

Currently, the company has three submersibles capable of carrying five-person crews into the ocean depths. Since 2021, the company has been offering tours of the Titanic wreckage site. An earlier attempt in 2018 was canceled after Titan’s electronics were damaged, followed by a second postponement in 2019 due to complications arising from Canadian maritime law.

Prior to its descent to the Titanic wreckage in 2021, Titan was rebuilt with assistance from NASA’s Marshall Space Flight Center after it was determined that the vessel’s depth rating was not deemed strong enough for travel to the 12,500-foot depth where the famous sunken British passenger liner rests.

The Debris Field: What the Search Effort Has Found So Far

Amidst poor weather that hampered search efforts on Wednesday, hopes remained as reports of “banging” sounds were detected by sonar operators.

CNN reported that according to an internal U.S. government memo related to the search, the strange banging noises had been heard every 30 minutes and were continuously detected following the deployment of additional ROVs.

However, on Thursday morning, a day cited as “critical” in terms of the likelihood that oxygen levels present on board the craft remained capable of supporting any surviving crew members, the U.S. First Coast Guard District announced on Twitter that a “debris field was discovered within the search area by an ROV near the Titanic.”


“Experts within the unified command are evaluating the information,” the Twitter post read.

Today at 3 PM Eastern, the U.S. Coast Guard is expected to hold a press briefing with additional details about their evaluation of the apparent debris field and other updates on the search effort.
