600 ft is threshhold
United States Submarine Operations in World War II was created in 1949.
The depth charge was invented during World War I, with its development credited to the British Royal Navy around 1916. It was designed to target submarines by exploding underwater at a predetermined depth. The weapon became a significant anti-submarine warfare tool during the war and continued to be used in subsequent conflicts.

The submarine.
It varies by the type of submarine. United States, Russia, United Kingdom, China, France, and India are examples of nations who have or are assumed to have nuclear submarine capabilities.For security purposes, governments don't give out full specifications on their weapons of war, especially on something as big, expensive, and instrumental as a submarine. The true depth information is classified, probably above "Top Secret". For the general US submarine fleet, the "official" answer is typically around 600 feet. (According to one Navy instructor it was changed from 400 feet when a documentary was aired accidentally showing footage of the depth meter at a depth of around that depth.)Any Navy in the world who operates a nuclear submarine is going to publish a low ballpark figure in the name of national security and secrecy. If everyone knew the exact depth a submarine could submerse to, it'd be easier to kill them. Wikipedia says a Soviet/Russian class Alpha submarine may have successfully operated at a depth of 4,300 feet. But rest assured whatever the published depth of submarine is, it many times greater than that.
