Dear Ms. Martin,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located a series titled Summaries of Radio Intelligence Japanese Naval Attache Messages in the Records of the National Security Agency/Central Security Service (Record Group 457) that includes the work of the Aleutian Task Force. For access to these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org.
We hope this information is helpful. Best of luck with your research!
