Dear Mr. Pavey,
Thank you for posting your request on History Hub!
We searched the Records of the Bureau of Naval Personnel (Record Group 24) and located deck logs of the USS Roark (DE-1053) from 1 January 1971 to 31 December 1972. For access to or copies of these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org.
We hope this information is helpful. Best of luck with your research!
