This is the maximum depth at which a submarine is permitted to operate under normal peacetime circumstances, and is tested during sea trials.The test depth is set at two-thirds (0.66) of the design depth for United States Navy submarines, while the Royal Navy sets test depth at 4/7 (0.57) the design depth, and the German Navy sets it at exactly one-half (0.50) of design depth.
Submarines of World War II represented a wide range of capabilities with many types of varying specifications produced by dozens of countries. The principle countries engaged in submarine warfare during the war were Germany, Italy, Japan, the United States, United Kingdom and the Soviet Union. The Italian and Soviet fleets were the largest.
With the stronger HY-80 steel, this depth increased to 1,800 feet (550 m) and with HY-100 a depth of 2,250 feet (690 m). [2] The first production submarines to use HY-80 steel were the Permit class. These reportedly had a normal operating depth of 1,300 feet, roughly two-thirds the crush depth limit imposed by the steel. [2]
The Seawolf class is a class of nuclear-powered, fast attack submarines (SSN) in service with the United States Navy. The class was the intended successor to the Los Angeles class, and design work began in 1983. [10] A fleet of 29 submarines was to be built over a ten-year period, but that was reduced to 12 submarines.

The Vanguard is a class of nuclear-powered ballistic missile submarine introduced in 1994 as part of the Trident nuclear programme. Each sub costs around £3.75 billion, measuring nearly 500ft ...
A depth charge of approximately 220 lb (100 kg) of TNT (400 MJ) would normally have a killing radius (resulting in a hull breach) of only 10–13 ft (3–4 m) against a conventional 1000-ton submarine, while the disablement radius (where the submarine is not sunk but is put out of commission) would be approximately 26–33 ft (8–10 m). A ...
The New Submersible. The new submersible will be known as the Triton 4000/2 Abyssal Explorer. The 4000 in the name refers to the depth it can reach, which is slightly more than where the Titanic ...
