NATIONAL SECURITY COUNCIL INTELLIGENCE DIRECTIVE NO. 6*
1. Communications Intelligence (COMINT) and Electronics Intelligence
(ELINT) and the activities pertaining thereto (as defined in paragraph 4
of this directive) are national responsibilities whose importance to
national security requires an organization and management which will:
a. Exploit to the maximum the available resources in all
participating, departments and agencies to satisfy legitimate
requirements for foreign intelligence relating to the national
security, including those of the departments and agencies concerned;
b. Provide for efficiency and economy in the use of technical
resources; and
c. Insure the necessary degree of protection.
Therefore, pursuant to the National Security Act of 1917, as amended,
the National Security Council authorizes and directs that COMINT and the
COMINT activities of the United States, as well as ELINT and ELINT acti-
vities, shall be conducted as prescribed herein. COMINT and ELINT and
their associated activities shall be treated as being within the framework
of general intelligence activities except as otherwise established under
this directive.
2. Only those departments or agencies represented on the U. S.
Intelligence Board (USIB) are authorized to engage in COMINT or ELINT
activities and only in accordance with the provisions of this directive.
*This directive supersedes NSCID No, 9, revised 29 December 1952, and
NSCID No. 17, dated 16 May 1955.
