The WSJ published the report on 2023-06-22, story last updated at 23:15 UTC:
The US Navy says the detection was on Sunday, 2023-06-18, and immediately reported to the Coast Guard commander on site. Scuttlebutt is that WSJ had the story days ago and sat on it, but this has not been confirmed.
The Navy did not disclose the sensors that detected the signal, but it is probably the SOSUS array.

Both Boeing and the University of Washington deny they helped design the lost Titan sub (source)
On the company’s website, OceanGate wrote that the Titan was “designed and engineered by OceanGate Inc. in collaboration [with] experts from NASA, Boeing, and the University of Washington.”
But two of those listed entities, Boeing and the University of Washington, are saying that’s not true. NASA, which did consult on the design, is now clarifying what its invovement did and didn’t entail.
In a statement sent to Insider, Boeing said the aircraft company was not involved with the development of OceanGate’s Titan.
“Boeing was not a partner on the Titan and did not design or build it,” a Boeing spokesperson said in an emailed statement to Insider. The spokesperson did not elaborate on any connection to OceanGate.
The University of Washington also released a statement saying that it wasn’t involved in creating OceanGate’s Titan submersible.
In a statement provided to CNN, University of Washington spokesperson Victor Balta said the university’s Applied Physics Laboratory was not involved in the “design, engineering, or testing of the Titan submersible.”
But we did sell them some old carbon fiber past its shelf life. We actually awarded the guy that made the sale our highest environmental award for reducing landfill waste.
My understanding is modern game controllers are in heavy use by the US military [1] as kids these days are used to them.

The guy who testified on 16SEP spoke of his experience with the submersibles of the Hawaii Undersea Research Laboratory. Those submersibles were only rated to 2000 m versus the ~4000 m required to reach the Titanic. Not too many submersibles can get to 4000 m.
The Hawaii submersibles (Pisces IV and V) were deployed from R/V Kaʻimikai-O-Kanaloa (KoK). I did a research cruise on the KoK in 2010 and snapped these pics of the Pisces submersibles.
