Through The Teak Wood CracksNot a quiz, I haven't a clue to the answer to this one, and finally realized there probably is not a better forum than Ultraquiet to get a reliable answer.
What was the last U.S. submarine to utilize teak wood decking as a working surface? (photo source)
SSN-575 (commissioned 1957) had it, but don't think she would have been the last one. There were several later boats before the Skipjack (SSN-585) class (launched 1959) which probably ended the practice. Triton (later in 1959) may also have had teak decking (it is not the type thing that is easy to remember).
If you thought that all of the older (than 1957) U.S. subs had teak decking (as I once did) you would be wrong. A link to related, post WWII information has been incredibly elusive to date.
