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.
[4] [15] In his book Submarine: A Guided Tour Inside a Nuclear Warship, Tom Clancy estimated the top speed of Los Angeles-class submarines at about 37 knots (69 km/h; 43 mph). The U.S. Navy gives the maximum operating depth of the Los Angeles class as 650 ft (200 m), [ 16 ] while Patrick Tyler , in his book Running Critical , suggests a maximum ...
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]

In 2020, Rush said that the hull, originally designed to reach 4,000 m (13,000 ft) below sea level, [15] had been downgraded to a depth rating of 3,000 m (9,800 ft) after demonstrating signs of cyclic fatigue. In 2020 and 2021, the hull was repaired or rebuilt. [16]

Those reports can be true - after all, the crush depth is just an educated guess or calculation based on the material used, hull thickness, heat treatment, etc. There are so many variables in it, and since any nation has a vested interest in keeping her subs and crewmen alive, these guesses and calculations about the crush depth are rather ...
The Ohio class of nuclear-powered submarines includes the United States Navy's 14 ballistic missile submarines (SSBNs) and its four cruise missile submarines (SSGNs). Each displacing 18,750 tons submerged, the Ohio-class boats are the largest submarines ever built for the U.S. Navy, and are capable of carrying 24 Trident II missiles apiece.
