Celebrating the 75th Anniversary of a Key U.S. Visit to Bletchley Park

The world's most important signals-intelligence liaison relationship – between the United States and the United Kingdom – began 75 years ago at Bletchley Park, the central site for Great Britain's codebreakers during World War II. The relationship became a practical reality on Feb. 8, 1941, with a visit by American personnel.

In 1946, the United Kingdom and the United States formally renewed their agreement to share signals intelligence. The agreement became the foundation of the Cold War intelligence alliance.

The relationship has continued unbroken to this day, allowing the countries to work together against common national security challenges.
