Permit class USS Plunger on the building ways at Mare Island. HY-80 is a high-tensile, high yield strength, low alloy steel.It was developed for use in naval applications, specifically the development of pressure hulls for the US nuclear submarine program and is still currently used in many naval applications.
The hull of the Albacore utilized HY-80 high-strength steel [3] with a yield strength of 80,000 psi (550 MPa), although this was not initially used to increase the diving depth relative to other US submarines. HY-80 remained the standard submarine steel through the Los Angeles class. [15] Other components were made from high-tensile steel (HTS ...

HY-119 refers to a Chinese underwater navigation and communication system," Dizon said. "It has an antenna and an eye that can be used for viewing. Based on our research, this can be used for ...
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 search for a submarine carrying five people that went missing on its way to view the wreckage of the Titanic continues on Wednesday, with a growing number of ships and aircraft joining the US ...
HY-80 remained the standard submarine steel through the Los Angeles class. [5] Control room of Skipjack class; the bow is at the top. Another Barbel-like innovation was the combination of the conning tower, control room, and attack center in one space. This was continued in all subsequent US nuclear submarines.
