Seems newsworthy, so why keep this from the public other than to control the news cycle.
https://www.wsj.com/articles/u-s-navy-detected-titan-sub-implosion-days-ago-6844cb12A top secret military acoustic detection system designed to spot enemy submarines first heard what the U.S. Navy suspected was the Titan submersible implosion hours after the submersible began its voyage, officials involved in the search said.
The Navy began listening for the Titan almost as soon as the sub lost communications, according to a U.S. defense official. Shortly after the submersible’s disappearance Sunday, the U.S. system detected what it suspected was the sound of an implosion near the debris site discovered Thursday and reported its findings to the Coast Guard commander on site, U.S. defense officials said.
While the Navy couldn’t say definitively the sound came from the Titan, the discovery played a role in narrowing the scope of the search for the vessel before its debris was discovered Thursday, the officials said.
