The S-80 Plus class (or Isaac Peral class) is a Spanish class of four submarines being built by the state-owned [10] Spanish company Navantia at its Cartagena shipyard for the Spanish Navy. In common with other contemporary submarines, they feature air-independent propulsion .
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] USS Thresher, the lead boat of this class, was lost in an accident in 1963. At the time, this unexplained accident raised much controversy about ...
The Balao class was a design of United States Navy submarine used during World War II, and with 120 [1] boats completed, the largest class of submarines in the United States Navy. An improvement on the earlier Gato class , the boats had slight internal differences.
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.
On 10 April 1963, while on a deep test dive about 200 miles off the northeast coast of the United States, USS Thresher (SSN-593) was lost with all hands. The loss of the lead ship of a new, fast, quiet, deep-diving class of submarines led the Navy to re-evaluate the methods used to build its submarines.
