VIDEO | 01:15 | Cryptology in the Vietnam War
This Museum exhibit displays an example of the cryptologic support provided during the Vietnam War. Numerous fixed field sites in Vietnam conducted both strategic and tactical collection missions and radio direction finding (DF). Throughout the war, all military services' cryptologic elements took part in providing tactical and strategic information to military commanders. The Army Security Agency used a wide variety of aircraft as well to conduct aerial reconnaissance missions. The U.S. Navy also began its surveillance as early as 1962, conducting shore, shipborne, and aerial reconnaissance. Information derived from signals and electronic intelligence flowed quickly back to the commanders in the field. National Security Agency civilians worked side by side with their military counterparts and the South Vietnamese. Those stationed at NSA in the United States worked around-the-clock processing, translating, and forwarding this vital intelligence.
