Dear Ms. Johnson,
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 log of the USS PCE 849 from 11 April 1943 through December 1950. We also located World War II Action and Operational Reports in the Records of the Office of the Chief of Naval Operations (Record Group 38) that may include reports submitted by the USS PCE(R)-849. For more information, please contact the National Archives at College Park - Textual Reference (RDT2) via email at email@example.com.
Photographs of various U.S. Navy activities dating from 1940 to 2007 are in the custody of the National Archives at College Park - Still Picture (RDSS). Please contact RDSS via email at firstname.lastname@example.org to request a search for photographs of specific ships.
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 and RDSS. We apologize for this inconvenience and appreciate your understanding and patience.
We also located World War II War Diaries, Other Operational Records and Histories, ca. 1/1/1942 - ca. 6/1/1946 in the Records of the Office of the Chief of Naval Operations (Record Group 38) which contains war diaries and reports concerning the USS San Diego’s activities during World War 2. These records have been digitized and can be viewed online through the Catalog. Please keep in mind that the Catalog does not always list files in chronological order.
Finally, the unofficial website NavSource has a page on the PCE(R)-849.
We hope this is helpful. Best of luck with your research!
