Rear Admiral John Mauger of the US Coast Guard said that the debris was consistent with a "catastrophic loss of the pressure chamber". [115] Mauger stated that he did not have an answer as to whether the bodies of those on board would be recovered, but he did say that it was "an incredibly unforgiving environment".

CCGS John Cabot arrived on the morning of 21June, bringing additional sonar capabilities to the search effort. Commercial vessels Skandi Vinland and Atlantic Merlin also arrived that day, as did a Coast Guard C-130 crew. [97] As of about 3:00 p.m. (17:30 UTC), five air and water vehicles were actively searching for Titan, and another five were expected to arrive in the next 24–48 hours. [98] Search and rescue assets included two ROVs, one CP-140 Aurora aircraft, and the C-130 aircraft. [98] Communication between Titan and its mother ship, Polar Prince, was lost 1 hour 45 minutes into the dive. Authorities were alerted when it failed to resurface at the scheduled time later that day. After the submersible had been missing for four days, a remotely operated underwater vehicle (ROV) discovered a debris field containing parts of Titan, about 500 metres (1,600ft) from the bow of Titanic. The search area was informed by the United States Navy's (USN) sonar detection of an acoustic signature consistent with an implosion around the time communications with the submersible ceased, suggesting the pressure hull had imploded while Titan was descending, resulting in the instantaneous deaths of all five occupants. Titan was driven by a reinforced Logitech game controller and touch screens, and the dive was said to have taken place in darkness in a bid to save battery power on lighting.
