Concerning the article on HY-80 steel, specifically the third and fifth paragraphs on the use of HY-80 in submarine construction, the article states that: "The later Skipjack class, although of the new Albacore 'teardrop' hull form, also used these earlier [low-carbon STS/HY-42] steels," and "The first production submarines to use HY-80 steel were the Permit class." Neither of these statements is correct. I was assigned to USS Skipjack (SSN-585) in 1963 and 1964, and know that she was constructed of HY-80 steel. That being the case, the Permit class were NOT the first "production submarines" to use HY-80 steel. I'm not quite sure how one might go about "verifying" those facts, but facts they are. Thus far the only corroboration I've found is at: https://fas.org/man/dod-101/sys/ship/ssn-585.htm, which reads in pertinent part, "The first submarine class to combine nuclear power with the new hull design was the USS Skipjack. USS Skipjack was also unique in that it was the first nuclear submarine with a single shaft. Placement of the bow planes on the sail greatly reduced flow noise at the bow-mounted sonar. Deep-diving and high speed capabilities were the result of HY-80 construction and a new reactor design, the S5W.
