Control, Communications, and Intelligence (C3I) Systems, November 12,
1992, ASD(C3I)

Refs: (a) DoD Directive 4630.5, "Compatibility and Interoperability of
Tactical Command, Control, Communications, and Intelligence Systems,"
October 9, 1985 (hereby canceled)
(b) DoD Directive 5000.1, "Defense Acquisition," February 23, 1991
(c) DoD Instruction 5000.2, "Defense Acquisition Management Policies and
Procedures," February 23, 1991

This Directive reissues reference (a) and promulgates policy for
compatibility, interoperability, and integration of C3I systems used in
the Department of Defense.


This Directive applies to:

1. The Off ice of the Secretary of Defense (OSD), the Military
Departments, the Chairman of the Joint Chiefs of Staff and the Joint
Staff, the Unified and Specified Combatant Commands, the Inspector General
of the Department of Defense, the Defense Agencies, and the DoD Field
Activities (hereafter referred to collectively as "the DoD Components").

2. All new C3I systems (including nondevelopmental systems) and major
changes (e.g. release of a new software version) to existing systems that
must interact with or be integrated into the C3I structures of the


Principal Staff Assistants.  Undersecretaries of Defense, Assistant
Secretaries of Defense, General Counsel of the Department of Defense,
Inspector General of the Department of Defense, Comptroller of the
Department of Defense, Assistants to the Secretary of Defense, and OSD
Directors or equivalents who report directly to the Secretary or Deputy
Secretary of Defense.


It is DoD Policy:

1. That forces for joint and combined operations must be supported through
compatible, interoperable, and integrated C3I systems that can support
operations worldwide throughout the entire spectrum of conflict.

2. To establish as a long-term objective a DoD-wide, global C3I
infrastructure that can accommodate the widest possible range of missions
and operational scenarios by allowing users to enter the infrastructure at
anytime, anyplace, in the execution of any mission.

3. In accordance with DoD Directive 5000.1 and DoD Instruction 5000.2
(references (b) and (c)), to develop, acquire, and deploy C3I systems and
equipment that meet essential operational needs of U.S. forces, that are
compatible with existing and planned C3I systems, and other electronic
equipment, and that are interoperable with other U.S. and allied nations'
functionally related C3I information systems and equipment.  See 10 U.S.C.
2457 (reference (d)), which establishes a policy of Standardization and
interoperability within the North Atlantic Treaty Organization.

4. That, for purposes of compatibility, interoperability, and integration,
all C3I systems developed for use by U.S. forces are considered to be for
joint use.

5. That interoperability and integration of C3I requirements shall be
determined during the requirements validation process and shall be updated
as necessary throughout the acquisition period, deployment, and
operational life of a system.


1. The Assistant Secretary of Defense for Command, Control,
Communications, and Intelligence shall assign responsibilities and
prescribe procedures, as necessary, to ensure the policies outlined in
section D., above, are carried out.

2. The Principal Staff Assistants shall, during all technical, program,
budget, funding, or other reviews of the Military Departments or the
Defense Agencies affecting compatibility and interoperability
requirements, make recommendations to the appropriate decision authority
about the conformance to the policies outlined in section D., above.

3. The Chairman of the Joint Chiefs of Staff shall:

a.  In accordance with references (b) and (c), establish procedures for the
development, coordination, review, and validation of compatibility,
interoperability, and integration requirements for the C3I systems.

b.  Approve, document, and exercise doctrinal concepts and associated
operational procedures to achieve compatibility, interoperability, and
integration of C3I systems employed by U.S. military forces and, as
appropriate, with coalition and allied forces.

c.  Establish procedures for and ensure compliance with certification of
joint interoperability of C3I systems throughout those systems' life-

4. The Heads of the DoD Components shall ensure that the provisions of
section D., above, are followed during the requirements validation
process, acquisition, deployment, and operation of systems and forces.


This Directive is effective immediately.
