Naval Security Group HFDF during the Cold War

I’m considering developing a presentation for the 2021 symposium on cryptologic history which will describe the NSG HFDF operations during the 1960s and 1970s. My first task will be to get permission from NSA to collect oral histories from HFDF operators. I’m not sure how successful I will be with that. However, the fact that oral histories from cryptologists in the WWII era were collected less than 40 years after the end of the war does give me some hope that some permission will be forthcoming.

There’s almost enough material in the excellent history of the Wahiawa Wullenweber commissioned by the National Park Service Historic American Buildings Survey to make up a presentation. You can find that report at:

This link gets you to the Library of Congress web site. You can download the full NPS reports using the “PDF” link on the left side of the page.

I included much of the text from this excellent report in my memoir after receiving permission from the NPS.
