Dear Mr. Santos,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located Records Related to "The History of Pilotless Aircraft and Guided Missiles", 1953 - 1958 in the Records of the Bureau of Aeronautics (Record Group 72) which includes information on the Regulus missile. The Records of the Bureau of Ships (Record Group 19), the Records of the the Bureau of Ordnance (Record Group 74), and the Records of Naval Operating Forces (Record Group) also have series which may include information about the USS Randolph and the Regulus missile. These records are in the custody of the National Archives at College Park - Textual Reference (RDT2).
