sure, they all can reach the bottom... most of the time you don't want them to though.
the ocean varies in depth everywhere depending on where you are. modern subs can't sit at the bottom like old WWII boats could, the new ones have delecate sonar equipment among other things on the bottom. depending on the class, us navy ships can dive to ~2000 ft. but normally operate much higher than that.
Straight to the bottom of the ocean.
yes at the bottom of the ocean.
With other submarines, ships and aircraft. Possibly also with detectors that sit on the bottom of the ocean and transmit a signal when a sub is detected.
submarines dont sail idiot
Yes, it does. The more you advance towards the bottom of the ocean, the more the water pressure increases. Which is why you implode before reaching the bottom.
With submersibles, sonar, magnetometers, and satellites.
The Southern Ocean which surrounds Antarctica is dangerous for any ship, and especially for submarines, because of the high-volume of icebergs.
Atlantic Ocean.
They send underwater submarines to study the ocean floor.
Both are similar as in man has not conquered both. Traveling to outer space or traveling to the deepest depths of the ocean are equally difficult and complex to accomplish.
