1961: Third Radio Research Unit began Army Security Agency service in South Vietnam.

On 13 May 1961, the first contingent of Army Security Agency personnel arrived in South Vietnam (setting up an organization at Tan Son Nhut Air Base) to provide support to the U.S. Military Assistance Advisory Group and help train the South Vietnamese Army. During the early years of conflict, ASA troops in Vietnam were assigned to the 3rd Radio Research Unit. Their primary mission was to locate Viet Cong transmitters operating in the south.

This mission was in its early stages when one of their direction finding (DF) operators, SP4 James T. Davis, was killed in a Viet Cong ambush on a road outside Saigon. The date of the ambush, 22 December 1961, made Davis the first American cryptologist to lose his life during the Vietnam War. Click the link below to learn about SP4 Davis in a special NSA pdf.

SP4 Davis' name is engraved on the NSA/CSS Cryptologic Memorial Wall. The wall, dedicated in 1996, lists the names of 176 Army, Navy, Air Force, Marine, and civilian cryptologists who have made the ultimate sacrifice, "serving in silence," in the performance of their duties since World War II.

  • Birthday of cryptologic machine designer Edward Hebern. Hebern's five-rotor cipher machine is cryptologically significant as part of the overall evolution in U.S. manufactured rotor devices. The National Cryptologic Museum has two very rare five-rotor Hebern cipher machines in its collection.

About Us

The NCMF directly supports the National Cryptologic Museum (NCM), the first public museum in the U.S. Intelligence Community. We think you will agree it is truly a "museum like no other."

Located adjacent to the National Security Agency (NSA) in Maryland, the NCM houses a priceless collection of artifacts that represent our Nation's history in code making and code breaking, as well as a world class library of cryptologic media. The NCMF acquires the best artifacts for the NCM and supports new educational and interactive exhibits.

The NCMF provides exceptional cryptologic programs throughout the year, encourages young minds to explore cryptology and innovation through valued awards, and hosts educational, cryptology-related exhibits at various community events.

As part of the Foundation's partnership with NSA to build the Cyber Center for Education and Innovation - Home of the National Cryptologic Museum (CCEI-NCM), the NCMF also serves as a leader in the field of cybersecurity - striving to provide the best in educational resources and programs.

The NCMF and NCM share a joint three-fold mission to Educate, Stimulate, and Commemorate. Learn more about our MISSION.
