With enough water and ballast on board, a submarine can submerge straight to the bottom of the ocean if you're not careful.
There are 3 specific depths that submarine crews maintain constant awareness of:
1. Test Depth
2. Crush Depth
3. Bottom Depth
Of course, it is extremely important that you don't hit #3 before #1 and #2.
Test Depth is the depth at which submarines submerge to in order to test repairs, maintenance on hull valves, and to verify hull integrity. It's also used to verify a boat's readiness for operations in preparation for a deployment. TD is generally a few hundred feet above Crush Depth, which is the structural failure point of the hull at which sea pressure will overcome the hull's integrity.
The actual TD and CD's of submarines are classified - even published figures are only estimates. For example, during the Cold War the Russian ALFA class SSN was estimated to have a crush depth of nearly 3000' - we know today that her TD was only around 1200', putting her CD a lot shallower than 3000'. Official acknowledgment by the U.S. Navy is greater than 400' for all U.S. submarines.
One of the arguments by politicians then was about how the Russians could build a submarine capable of going to such depths when NATO couldn't. The answer was as simple then, as it is today; at such depths, you don't need another submarine capable of following them that deep. You only need a torpedothat's fast enough and can dive that deep to catch them. At that depth, it doesn't take much damage to cause a major unrecoverable casualty.
The materials which a submarine are constructed with affect a boat's overall depth capability as well. U.S. and NATO submarines are typically constructed of highly flexible steel which can withstand repeated excursions to deep depths, and can contract and expand with sea pressure changes.

What are the steps to submerge a submarine?
To submerge a submarine, the crew first ensures all hatches are secure and the vessel is ready for diving. Then, they activate the ballast system, which fills ballast tanks with water, increasing the submarine's weight and causing it to sink. The crew monitors depth and pressure, adjusting the ballast as needed to control the descent. Finally, once submerged, they can trim the submarine to maintain a desired depth.
Why does the submarine float and submerge in water?
Submarines must be able to float to load and offload crew and cargo and to have repairs and maintenance. They are designed to submerge either for underwater exploration or to pass undetected by ships at the surface and planes and satellites above.
What are people in a submarine called?
The submarine is manned by the crew, and crew members are called submariners.
What do submarine cooks do?
They prepare meals for the crew
Is there a list of crew members of the m1 submarine lost 1925?
The M1 submarine was lost at sea in 1925. There is a list of the crew members lost that day online.
How many men are on a submarine?
The number of men on a submarine varies depending on the type and class of the vessel. Generally, a U.S. Navy submarine can have a crew size ranging from about 70 to over 150 personnel. For example, a typical fast attack submarine like the Virginia-class usually has around 130 crew members, while a ballistic missile submarine like the Ohio-class can carry approximately 150 crew members.
What did the crew do on the submarine in World War 1?
they copied there butts
How long can a submarine be in the water?
A nuclear powered submarine can remain submerged for as long as it has fuel rods and supplies for the crew.
How big was the first submarine?
The first submarine was about 46 feet in length and assembled in Barcelona, Spain. The first successful launch of this submarine was in 1864 and held a crew of two people.
How many men made up the crew of the Seal a German midget submarine?
about 22million
How many men made up the crew of the Seal a midget German submarine?
about 22million
What technology was developed to help sailors escape a submarine accident?
The technology developed to help sailors escape from a submarine accident is known as the Submarine Escape and Rescue (SMER) system. This system includes various escape pods, such as the "DISSUB" escape capsule, which allows submariners to safely ascend to the surface in case of emergencies. Additionally, advanced technologies like the "Submarine Rescue Vehicle" (SRV) are designed to rescue trapped crew members by docking with the submarine and providing a safe means of escape. These innovations have significantly improved the safety and survivability of submariners during emergencies.
