Web sites related to WW2 cryptology
Note: It’s always sobering to check for broken links, and I’ve found that this page had its share. If you should hit a dud, please (a) be patient; (b) consider using Google to find the correct link and (c) drop me an email so I can refresh the link.

Essential background information
- Documents specific to the American Bombe posted by Frode Weierud
- Information about the Battle of the Atlantic posted by the Mariner’s Museum of Newport News, Virginia
In particular, see …
- The Information Age: The Smithsonian Exhibit where the US Navy Bombe made its first public appearance
- For some reflection on the Information Age: 5 Myths About the ‘Information Age’
The role of cryptology in American history:
- NSA Cryptologic Heritage
- The National Cryptologic Museum
- And it follows, the National Security Agency, heir to the technologies developed at the US NCML.
- New to the NSA History site: Index and online copies of many of their publications
- Naval Security Group Command, descendent of Op-20-G (NB: COMNAVSECGRU was disestablished 29 Dec 2005. Those former commands are now renamed Navy Information Operations Commands. For more information, please see this web site.)
- Navy CT History , the “unofficial” web site, preserving the history of the Naval Security Group Command and the worldwide CT community.
- Background on the US Navy’s cryptologic efforts in the Far East: The Empire is Listening, published in the Journal of the Australian War Memorial.
I.E.E.E. History Center interviews with 7 of the NCR personnel who worked on this project
Background information about the Medal for Merit
Information about the U-boat wars
- U-boat Archive.net
- The Merseyside Maritime Museum, Liverpool England
- Naval-History.net/Preserving Naval History Research and Memoirs
NB: For the first time I’ve come across a large site, purported to be the most accurate WW2 history site online, yet with no authorship or sourcing. A great deal of work obviously went into the construction of this site yet there’s no mention of credit. A word to the wise, be careful to check credentials and sourcing. This site may be worthwhile but I’m steering clear.
The pioneering work of the British at Bletchley Park, and Bletchley’s relationship with the US:
- Index to Frode Weierud’s CryptoCellar a site of varied and extensive information.
- The Official Site of the Bletchley Park Trust–updated and loaded with new information.
- Codes and Ciphers in the Second World War, hosted by Tony Sale
- A section of The Alan Turing Internet Scrapbook, Alan Turing as UK-USA link, 1942 onwards: Hands Across the Sea
- The Alan Turing Archive
New: The admirable and now successful efforts of the Bletchley Park Trust not only to save Bletchley Park but educate the public about the Park’s heroic efforts during WW2
- BCS Bombe Team receives Award
- John Harper, Leader of the Bombe Rebuild Team receives Honorary Fellowship of BCS” Bletchley Park News.
- Enigma replica ‘homage to heroes’ BBC News.
- Engineering award for legendary Enigma-busting kit John Harper, from 1995 to 2006, led a Computer Conservation Society team rebuilding a working World War II Bombe decryption device. On 6 September 2006, John Harper and the rebuild team first demonstrated the working Bombe in action
Information about the ground-breaking work on cracking the Enigma accomplished by Polish cryptanalysts early in the War:
- An essay on machine ciphers and their solutions by Chris Christensen, which outlines the Polish efforts
- The Enigma Machine; History of Solving, hosted by Lech Maziakowski
Sites dedicated to our veterans:
- The Navy Memorial Foundation
- The U.S. Naval Cryptolgic Veterans Association
- The U.S. Navy Historical Center
- Women in Military Service for America Memorial
- WAVES National , a site I highly recommend to families researching a member’s service record.
For a glimpse at Dayton’s role in international cryptologic history, visit the web pages of the Dayton History.
- Among their assets is the immensely valuable NCR Archive
Would you like to learn more about codes and ciphers, encrypt a message, or learn more about tubes and circuits? decrypt other ciphers? tackle Enigma itself?
- Enigma replicas, site belonging to a good friend, JIm Oram, restorer of Enigmas for museums and collectors, with volumes of information about versions of the Enigma. Jim also is devoted to the Graveyard of the Atlantic
- Elonka’s List of Famous Unsolved Ciphers and Codes
- Another look at methods of Enigma decryption
- The home page of a web site (somewhat technical) by Jerry Proc, of Ontario Canada, devoted to Crypto Machines.
- The Dutch Crypto Museum, a virtual museum sponsored in the Netherlands. Included is a list of Enigma simulators available for different operating systems (Windows, Perl, etc.)
- and how to build your own: Learn about the Enigma machine. Get a Kit to build your own!
- Something different: learn about the RCA Selectron, the Radar Tube “the tube that changed the war”
Excellent background information based on primary sources:
- Best of History Web Sites
- A long scroll but loaded with links: World War II Resources
- An excellent reference with a misleading name: Hyperwar; a Hypertext History of World War II
- Site sponsored by the History Department at Ohio State University: E History
