The "Berlin Tunnel" is generally considered one of the outstanding Allied intelligence successes of the cold war.   The project was compromised from the beginning by a Soviet mole, George Blake, working within British intelligence MI6.  Even so, the KBG did not inform the Soviet military and diplomatic interests of the intelligence penitration by the Allies in order to protect Blake's valuable position.

High-ranking KGB defectors have contended that no attempt was made to channel disinformation through the "tapped" telephone and telegraph lines as it was felt that the information gathered, though highly valuable, was tactical rather than strategic and therefore its value would diminish over time.

Accepting this as being true, one can assume that had a military or diplomatic flare-up occured during the tunnel's operation, that the intelligence gathered would have played an important role in developing an Allied response.

The American CIA and NSA as well as the British MI6 cooperated on the project.  The various intelligence organizations assigned their own code names to the project, which even today, offers some element of confusion when referencing material associated with this highly secret operation.

It should be noted that the material displayed here has been obtained through the Freedom of Information Act, various declassified documents or information routinely found in the Public Domain.  No material has been taken from classified sources.

Even after the public "exposure" of the Tunnel, the Rudow facility was used by the 280th ASA as an electronic intelligence gathering site.
