All submarines have a rated "Crush Depth", the depth at which the hull will succumb to external sea pressure.
While the actual depths for each class are classified, several submarines were lost during the Cold War to implosion events after major casualties. The most noted for the United States was the USS Thresher (SSN-593) which was lost during sea trials after she suffered a major flooding casualty. It was estimated she made it to within 100' of the surface before sinking to her crush depth and the bottom of the ocean.
a Submarine?
Commonly known as a Submarine
That is the correct spelling for "submarine" (underwater, or underwater vehicle).
As far as I can remember, there was never an underwater Russian submarine in Diamonds Are Forever. The underwater Russian/Soviet submarine was destroyed after the USA Titan II missile base was blown up, and before the Chinese missile base was blown up. Your memory is not very good.
As regards torpedoes or missiles, yes, the submarine has weapons that can be launched underwater.
The critical submarine implosion temperature is the temperature at which a submarine's hull collapses due to the pressure difference between the inside and outside of the vessel. This implosion can have a significant impact on underwater structures, causing them to fail and potentially leading to catastrophic consequences.
Just like gases, water exerts pressure due to its weight, and this pressure increases with depth. As a submarine descends, the water pressure surrounding it intensifies, which can be fatal if there are structural weaknesses in the hull. If these weaknesses are not addressed, the immense pressure can cause the submarine to be crushed, compromising its integrity and safety. This is why submarines are designed to withstand significant underwater pressure.
No, the body of a submarine is not typically referred to as a "fuselage." The term "fuselage" specifically describes the main body of an aircraft, while the corresponding term for a submarine is "hull." The hull is designed to withstand underwater pressure and provides the submarine's structural integrity.

A vessel that travels underwater is termed a submarine.
