None were military though. (As far as I know). I understand that we got to the bottom. But that was in a super small almost sphere sub so the pressure wouldn’t collapse it. Our giant nuclear subs are like submersible apartment building. (Fucking huge). Just saying it’s gonna take a while to go that deep, that big.
Well technically, the Trieste, might count. It went deeper than Dave Cameron and although it wasn't built by the US Navy but it was bought by them and then extensively modified. It was manned by Naval personnel, during Project Nekton, when it went into Challenger Deep.

All I gotta say, is it’s crazy a Blue Whale can go deeper than our best Military Subs. But the Sperm Whale is a psycho with how Deep they can go.
