TICOM: The Last Great Secret of World War II

ABSTRACT: Recent releases from the NSA reveal details of TICOM, the mysterious 1945 operation targeting Germany's Cryptologic secrets. Often motioned by such authors as Kahn, Bamford, Parrish and Aldrich, for the first time the public has access to this in-formation. This paper provides a review in greater depth than has been previously covered in the open literature of the history of the Ticom operation, and its resulting intelligence. In addition, some comments are provided on why Ticom has remained classified long after other similar information from World War II was declassified, and why locating TICOM documents is still difficult.
