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, RDSC, and RDSM. 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 includes war diaries for LCI(L) Flotilla 10 to which LCI(L)-87 was assigned in parts of 1943 and 1945. These diaries have been digitized and can be accessed online through the Catalog.
In addition, we located articles about the LCI(L)-87, the Coast Guard-Manned Landing Craft (Infantry), Large Flotilla 4 / 10 / 35, and U.S. Coast Guard-Manned LCI(L)s - Landing Craft Infantry (Large) on the website of the United States Coast Guard Historian’s Office. We also located a photograph on the website of the Naval History and Heritage Command, and an article on the unofficial website NavSource about the LCI(L)-87.
We hope this information is helpful. Best of luck with your research!
