Dear Mr. Shaw,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Logbooks of U.S. Navy Ships and Stations, 1941 - 1983 in the Records of the Bureau of Naval Personnel (Record Group 24) that include the deck logs of the USS Washtenaw County (LST-1166) for 29 October 1953 through 9 February 1973 when it was redesignated MSS-2, and the USS Washtenaw County (MSS-2) from that date through 30 August 1973. Some of these deck logs have been digitized and can be viewed online using the Catalog. Please note that the Catalog does not always list logs in chronological order. When viewing logs for each month, you may wish to click on the red PDF icon under the “Documents” heading. This will allow you to view the entire month’s logs as a single file. Once you have done so, you may use the blue download button to download the PDF. Due to the size of the files involved, it may take a little while for them to load in full. Please be patient. If you have any problems accessing these files, please email Catalog@nara.gov.
For copies of the logs that have not been uploaded yet to the Catalog, please contact the National Archives at College Park - Textual Reference (RDT2) via email at email@example.com. Due to the US Navy’s use of social security numbers for service numbers beginning in 1971, there may be restrictions on access to the 1971 through 1973 logs for reasons of personal privacy.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2. We apologize for this inconvenience and appreciate your understanding and patience.
The National Archives does not have command histories for individual ships. Command Operations Reports are the equivalent of a command history and are in the custody of the Naval History and Heritage Command (NHHC). NHHC also published an article about the Washtenaw County on their website as part of the Dictionary of American Naval Fighting Ships.
We hope this information is helpful. Best of luck with your research!
