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.
United States Navy submarine tenders are U.S. Navy vessels, common throughout World War II, stationed in remote areas of the oceans to service submarines assigned to them. Such service would include providing fuel, food, potable water, spare parts, and some repair of submarine equipment and minor hull components.
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 ...
Low-carbon STS was used in the experimental submarine USS Albacore and the aircraft carrier USS Forrestal. Low-carbon STS became the forerunner of HY-80, which eventually became the standard steel for submarine construction during the Cold War. [2] [3]
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.
Also like Albacore, the Skipjacks used HY-80 high-strength steel, 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. [5] Control room of Skipjack class; the bow is at the top.
But 80 years ago, you could see and maybe even touch evidence of the enemy. On Sept. 21, 1943, at the height of World War II, a Japanese submarine was parked on the street just south of where the ...
USS Topeka (SSN-754) is a Los Angeles-class submarine and the third United States Navy vessel to be named for Topeka, Kansas.The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut, on 28 November 1983 and her keel was laid down on 13 May 1986.
