The ‘New’ National Cryptologic Museum Showcases Secretive History of American Espionage

Some exciting news for spy geeks, history buffs, and anyone who wants to see rare codebreaking artifacts from days of yore: The National Security Agency has recently announced the “grand opening” of the National Cryptologic Museum in Annapolis Junction, Maryland. Although the museum, which is located near the NSA headquarters, has technically been open to the public since 1993, it was closed for renovations during the COVID-19 pandemic and its transformation was apparently significant enough for the NSA to call this a grand opening. The ribbon-cutting ceremony is Saturday, Oct. 8, at 10 a.m., at which point ordinary citizens will be welcomed inside to feast their eyes on a vast collection of encryption machines, supercomputers, and even invisible ink chronicling the role of cryptology in American national security.

Cryptology, as defined by the NSA, is the art and science of breaking and making codes and ciphers. Early uses in American history occurred as far back as the American Revolution, but it was seen prominently during the Civil War, when the Union and Confederate armies delivered and intercepted encrypted messages on the battlefield. As codebreaking technologies advanced with each new war, armies developed increasingly sophisticated means to protect crucial intelligence — such as battle plans and tactical protocols — from the prying eyes of adversaries. These efforts were undertaken on both minute and grand scales. For example, in World War II, the US Army recruited Navajo men to transmit sensitive military communications coded in their tribal languages. While the "Navajo Code Talkers" were effective on the ground, other techniques protected the broader schemes of America's military strategy, such as SIGABA, a complex cipher encryption machine. Axis forces never succeeded in breaking either the Navajo or the SIGABA codes. Then, during the Cold War, when the US and Soviet Union were on the brink of nuclear armageddon, the art and science of cryptology advanced well beyond esoteric languages and radios and into the realm of computer technology.
