References: See Enclosure B

1. Purpose. In accordance with Enclosure B, reference a, issue policy and

guidance for planning, coordinating, and controlling electromagnetic spectrum
use in joint military operations. To develop and implement joint doctrinal
concepts and associated operational procedures to achieve interoperability of IT
and NSS capabilities employed by US military forces and, where required, with
joint, combined, and coalition forces and other USG departments and agencies.
References a through o are provided for further reading.

2. Cancellation. CJCSI 3320.01, 1 May 2000, is canceled.

3. Applicability. This instruction applies to the Joint Staff, Services, unified

commands, US elements of combined commands, Defense agencies, and joint

4. Policy. Assured access to the electromagnetic spectrum is vital to DOD

operations worldwide. This publication identifies basic considerations for
operating spectrum-dependent systems in a joint military and civil

a. Joint Spectrum Environment. Military operations rely heavily on

equipment using the limited resources of the electromagnetic spectrum. In
joint military operations, requirements may exceed the amount of spectrum
available. As a result, efficient use and control of the spectrum is critical to
national security in terms of IO, combat operations, and C2W. Effective
spectrum management (the organized control and use of the electromagnetic
spectrum) is fundamentally essential to sound defensive IO and C2 protection,
which ensures operations can be conducted with minimal unintentional
CJCSI 3320.01A

interference and without negative E3. The rapid growth of sophisticated

weapons systems, as well as intelligence, operations, and communications
systems, greatly increases demand for frequencies. Lack of proper, preplanned
frequency coordination will have an adverse effect upon friendly but competing
users. Spectrum availability is further constrained by national legislation
designed to carefully protect the rights of sovereign governments by requiring
approval prior to transmission in any portion of the spectrum that lies within a
particular country’s national borders. Joint and combined force operations
must also consider the needs of coalition forces in future contingencies.
Therefore, an effective spectrum management structure is required not only to
satisfy spectrum needs of military users, but also to coordinate with host
nations to facilitate effective use of this finite resource. Further spectrum
issues are discussed within the Enclosure B references.

b. Electromagnetic Spectrum Planning, Coordination, and Control. To use

the spectrum successfully, all users must work together by exchanging vital
spectrum information from the beginning of the joint planning process through
execution of any operation via Spectrum XXI architecture. Primarily, personnel
assigned to operations directorate of a joint staff (J-3), intelligence directorate
of a joint staff (J-2), and communications directorate of a joint staff (J-6)
functional areas plan, coordinate, and control joint military use of the
electromagnetic spectrum. To minimize unacceptable EMI among all emitters
and receivers and to address E3 issues in joint operations, these three
functional areas must work together. Additionally, automated spectrum
management systems at the joint and component levels require vertical and
horizontal interoperability.

c. Concept of Control. The supported JFC or CJTF holds the authority for
assigning frequencies to users, usually through the Joint Frequency
Management Office or Joint Spectrum Management Element. The JFMO or
JSME may on occasion delegate frequency assignment authority to subordinate
commands, decentralizing the management of the electromagnetic battlespace.
Authority to assign use of a specific spectrum resource (utilization of allotment
plans developed by the JFMO or JSME) should be delegated to the lowest level
of command possible, consistent with the principles of sound spectrum
management, spectrum use considerations, concept of operations, and priority
of mission functions detailed in the respective Service or joint publications.
Subordinate commands delegated authority for approving spectrum use will
make frequency assignments within the constraints imposed by higher
authorities and report changes in spectrum assignment information to the

d. Spectrum Assignment Conflicts. To ensure critical frequencies and

spectrum-dependent systems are protected from unintentional interference
because of friendly operations, the J-6 coordinates, publishes, distributes, and

CJCSI 3320.01A
30 September 2002

maintains a Joint Restricted Frequency List based on inputs from the

J-2, J-3, and J-6. The J-3 must approve the coordinated JRFL prior to its
release. This is accomplished within the IO Cell. As new requirements are
identified, situations of conflicting or competing use of the spectrum will occur.
Conflicts within a primary functional area are resolved at the lowest possible
level by CJTF, JFC or JFMO. For conflicting or competing use that affects
more than one primary functional area, the IO Cell examines requirements and
attempts to resolve coordination issues with JFMO or JSME. If resolution is
impossible at this level, the matter is elevated to JFC or designee, who is
usually the JFMO or JSME.

e. Joint Spectrum Assignment Planning. Planning for use of the spectrum

resource and assigning of spectrum management responsibilities must be fully
integrated into the JOPES process. The complexity of effective joint spectrum
use and management requires advance planning for scenarios of expected
military operations. Each joint and subordinate component command must
establish planning procedures to address all spectrum-dependent systems
used in support of an OPLAN and any other requirements of friendly forces that
impact the use of the electromagnetic spectrum. Spectrum managers must be
fully integrated into the planning process at the initial and subsequent
planning stages. Additionally, planning must be done in a consistent manner
with each joint command. Without advance spectrum-use planning, EMI
among users and/or a shortage of assigned frequencies may become a severe
limitation to rapid deployment and employment of forces.
