The Honorable Neil H. McElroy
Secretary of Defense
Department of Defense
Washington, D. C,
Dear Mr. Secretary;
In accordance with recent instructions from the National Security
Council, I am sending to you the requirements of the Intelligence
Community for the communication of critical intelligence, as developed
in the Intelligence Advisory Committee.
Critical intelligence has been defined as "that intelligence indicating
a situation or pertaining to a situation which affects the security or
interests of the US to such an extent that it may require the immediate
attention of the President." Although it is impossible to predict all
eventualities, we believe that most critical intelligence will originate
with one or more collecting agencies reporting from the locations on the
list contained in Annex A to this letter. It is essential that these
locations have adequate communications to handle critical intelligence
with the speed desired. In view of our inability to predict all cases,
however, it is essential that there be a capability to provide communi-

In order to provide continuing advice and guidance as to intelligence
requirements to the Executive Agent for Communications, the Intelligence
Advisory Committee has formed a Critical Communications Committee under
the chairmanship of Mr. William A. Tidwell of the Central Intelligence
Agency. It is recommended that the Secretary of Defense call upon this
Committee to sit with his communications authorities.
Sincerely,
Allen W. Dulles
Director
