1985: Retired CWO John Walker was arrested for spying.

20 May 1985: Retired CWO John Walker was arrested for spying. For 18 years, John A. Walker Jr. sold U.S. secrets to the Soviets, both as a crypto custodian in the Navy in Norfolk and after he retired. It was estimated that he pocketed about $1 million. The U.S. Navy communications specialist passed classified documents, including navy code books and reports on movements of submarines and surface ships, to agents of the Soviet Union. At first obtaining the documents himself while on active duty, he subsequently recruited a close friend, a brother, and his own son into a growing spy ring that he maintained after his retirement from the military. The espionage activities of the Walker spy ring were described by some officials as among the gravest security breaches in the history of the U.S. Navy, and one of the biggest in the nation's history.

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.
