Yes. You can exit through the escape trunk. You would normally use some form of protective gear such as the long-discontinued Momsen Lung, a Steinke Hood or the U.S. Navy's new Submarine Escape and Immersion Equipment to survive the ascent to the surface.

Misunderestimated is exactly right. I can expand on this a bit. Escape trunks on submarines are designed so that several people can enter, shut the bottom hatch, then flood the hatch most of the way with seawater. The hatch is then pressurized with air to allow the upper hatch to open. When the hatch is opened, the Sailors can swim out using scuba, escape apparatuses, or even holding their breath if the sub is shallow enough. The depth at which anyone can escape/leave in this manner from a submarine is limited to the pressure that the escape trunk can be pressurized (classified). Another limit is the bottom time for nitrogen absorption while pressurized. From what I remember of my training, we had 90 seconds to start pressurizing, open the hatch and reach the surface if we were to avoid the bends while escaping from depths of 500-600 feet. It is impossible to raise pressure this high this fast without rupturing eardrums, nor is it possible to rise this fast to the surface. Escaping a deeply submerged submarine without using a DSVR (rescue sub that connects to the escape hatch) will result in severe injury or death.

Yes, so long as it is not too deep. Submariners have trained to do it since before WWII. You have to flood the compartment, hold your breath (or put on a scuba suit), and open the hatch when the pressure is equalized, then swim to the surface, exhale all the way up, and be treated for the bends (that's why you can't do it too deep).

Not usually. The pressure of the water will keep you from being able to lift the hatch open. Once the submarine is flooded, though, and the pressure is equalized between outside and in, then you can open the hatch.
There are some submersible vehicles that have an open bottom - the pressure of the air in the vehicle keeps water from bubbling up through the hole and into the vehicle. But they have a limit as to how deep they can go.

the sub might ought to establish an antenna on a glide, as salt water might brief out any sign above VLF. the U. S. does use VLF indicators to touch subs underwater. this operates at frequencies of roughly 10 kHz, and has an extremely low documents fee. .

One way is to open a door on the floor of the sub. The pressure inside the sub will prevent the water from entering. Think of turning a glass upside-down, then pushing it under water. The mouth of the glass is on the bottom and no water will fill the glass.

Yes, If you are wearing a wetsuit and scuba gear, you can go through an airlock to the outside. You have the option of re entering also.

yes depending on how deep you are, if you are only 50 feet underwater then yes but 500+ then no the pressure is too great and you would not be able to open anything to get out

Of course, but you have to have a chamber you can equalize to the water before you go out. Otherwise you'd flood the entire sub and sink it.
