Isn’t that kind of the idea behind a submarine?

Parts of it washed up onto madagascar and reunion island.
Also fun fact, the US Navy found a submarine lost on the sea floor with “it’s somewhere in the atlantic between Rota Spain and Norvolk Virginia” as a starting point and calculated its position within 200 yards

Just wait until Elon brings up the idea of building ankther ship for seafloor mining of manganese nodules. He’ll definitly be up to something if he does that

Well, there was the actual sealab programs which provided major advancesments in saturation diving for deep sea divers, so there was that

When underway, a submarine will generally not use their active sonar as using it kinda defeats the whole purpose of a submarine. It’d be like turning on a flashlight in a dark room when you’re trying to not be seen. Subs rely on passive sonar mostly, so unless an uncharted undersea mountain is transmitting noise, it’s invisible

Reply to comment by Beli_Mawrr in TIL: Thanks to poor internal communication at NASA, information about a spacesuit water leak wasn't properly communicated. Later, Astronaut Luca Parmitano almost drowned on a July, 2013 ISS space walk, his helmet filling with several liters of water before they could get him back inside. by OvidPerl
It’s not like poking a small hole in a space suit would cause instant decompression of the entire suit. The difference in pressure isn’t big enough for that. There was a 2mm hole on a spacecraft docked with the ISS, and it was determined that was no danger to the station and could easily be repaired
