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.
MSM-1 USEL was the first submersible vehicle for underwater research and work of completely Italian conception. The basic design of MSM-1 USEL was done by ESCO of Milan.The pressure hull is made of HY-80 steel and subdivided in two compartments: a cylinder with hemispherical ends located aft, and a sphere forward, interconnected by a cylindrical tunnel.
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-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.
The first submarine commissioned in the class was the ill-fated Thresher, and so the class was known by her name. When Thresher was lost on 10 April 1963, the class took the name of the second ship in the class, Permit. Thresher had numerous advanced design features and embodied the future of US Navy submarine design, and her loss was a serious ...
A U.S. nuclear-powered submarine arrived in the South Korean port city of Busan on Sunday, the Yonhap news agency reported citing the South Korean navy. The arrival of the USS Missouri, also known ...

They were of double hull design with 1.5-inch thick HY80 steel. This class of submarine became part of the United States Navy's fleet in 1959 and was taken out of service 1988–1990, leaving the Navy with an entirely nuclear-powered submarine fleet. The Barbel class' design is considered to be very effective. [3]
