Not a comment on the quality of the boats built by various nations, but when it comes to longevity the USS Threadfin MAY be the winner. Commissioned in 1944, sold to Turkey in 1972, and operated until 1998. 54 years! It is my understanding that she had depth restrictions in her last few years of service.
