Dear Mr. DiDomenico,
Thank you for posting your request on History Hub!
We searched online and located a similar report by H.A. Burch for another ship lost in May 1942. According to A Century of Naval Intelligence, the office code Op-16-B-5 in the heading references a section within the Office of Naval Intelligence.
We then searched the National Archives Catalog and located World War II Command Files in the Records of the Office of the Chief of Naval Operations (Record Group 38) that includes the file Chief of Naval Operations (CNO) Office of Naval Intelligence (ONI) Summary of Survivor Statements May 1942. The same series also includes the file Chief of Naval Operations (CNO) Office of Naval Intelligence (ONI) Tables of Ship Losses British/Allies/U.S./Neutral Losses by Month January-November 1942. In addition, we located the Central Administrative Correspondence, 1930 - 1948 for the ONI in Record Group 38 that may include reports regarding merchant ship losses filed under file headings L11-1 and QS. Plus, we located Papers of Vice Admiral Homer N. Wallin, 1941 - 1974 in Record Group 38 which includes Survivor's Statements in box 2.
Next, we located Merchant Vessel Information Files, 1939 - 1952 and Central Correspondence Files, 1936 - 1950 in the Records of the U.S. Maritime Commission (Record Group 178) that includes information about US Merchant Marine vessels, to include war casualties. Further, we located Reports Relating to Rescued Survivors of Wrecked Ships and Aircraft, 1942 - 1945 in the Records of the Bureau of Medicine and Surgery (Record Group 52).
