After days of intense searches for a submarine headed for the wreckage of the Titanic, US authorities have announced that the ship suffered a “catastrophic explosion”and a source in the US Navy shows when this could happen, foreign media reported.

The U.S. Navy on Sunday detected what sounded like an explosion in the area where the submarine Titan was sinking in the Atlantic Ocean when it lost contact with a support ship, a senior Navy official said. CNN.

All five people aboard the Titan submersible were killed, the US Coast Guard said at a press conference on Thursday. The tail cone and other wreckage of the missing submersible were found by a remotely operated vehicle about 487 meters from the bow of the Titanic, which lies at a depth of about 4,000 meters in the North Atlantic Ocean.

“The debris is consistent with a catastrophic ship explosion,” Rear Admiral John Mauger, commander of US Coast Guard District One, told reporters.

The U.S. Navy immediately relayed the information to commanders on the ground coordinating the search, the official said Thursday, adding that the information was used to narrow the search area.

But the sound of the explosion was not considered “convincing”, the official said, and the international search and rescue mission for the submarine’s crew continued.

“Any chance to save a life is worth continuing the mission,” the source was quoted as saying.

Elements of the underwater vehicle found near the location where the sound was detected

The Wall Street Journal was the first publication to report on the sound signal recorded by the US Navy.

A top-secret acoustic detection system used by the Navy to identify enemy submarines recorded the sound of an explosion for the first time Sunday near the site of the wreckage, U.S. defense officials said.

According to the WSJ, cited by Business Insider, Navy officials began searching for sounds from the Titan submersible almost immediately after it lost contact.

The network of sensors allowed the Navy to pinpoint the possible location of the noise, giving search teams a more precise search area.

The Navy also helped analyze other acoustic data heard during the search. It was likely a natural life form or sounds made by other ships and ships involved in the search, the official said.

The American authorities completely reconstructed the body of the underwater vehicle, discovering five elements. According to representatives of the coast guard, the first signs indicate a “disruption”.
