General.
a.
Background. Executive Order 12472 establishes national policy guidance in
support of National Security and Emergency Preparedness (NS/EP) objectives. This guidance
mandates that action be taken to A...ensure that a national telecommunications infrastructure is
developed... .@ Consistent with the Executive Order, functionally similar government telecommunications networks should be designed to interchange traffic in support of national leadership
requirements. The NCS is responsible for implementation. A segment of this effort addresses
the sharing of federally controlled HF radio resources to establish a robust national emergency
HF communications infrastructure. Thus evolved the SHARES (derived from SHAred
RESources) HF Radio Program.
b.
Objectives. Objectives of the SHARES High Frequency Radio Program are to:
(1) Provide participating agencies with extended high frequency coverage and
enhanced emergency high frequency radio communications at no added cost.
(2)
Provide an enduring backup to vulnerable leased telecommunications.
(3) Provide the flagword SHARES to expedite identification and processing of
emergency Federal government traffic.
(4) Standardize message preparation and procedures to simplify interagency
handling of NS/EP traffic.
(5) Provide possible work-around to jamming by permitting interagency
operation on allocated frequencies identified for SHARES use.
c.
Concept of Operations. The document entitled AA Concept of Operations for a
Shared Resources High Frequency Network (SHARES)@ (Appendix A), approved by the NCS
Committee of Principals, sets forth in detail the mission, operational concept, responsibilities of
Federal entities, and the sanctioning process for SHARES. It also defines the criteria for
frequency selection and coordination which is the most critical factor in establishing the
SHARES HF radio capability. The Concept of Operations subscribes to the following tenets:
(1) Any participating Federal entity will accept, to the extent that acceptance
does not interfere with the mission responsibilities of the entity, emergency messages of other
Federal entities, or other components of the same entity, for transmission by HF radio to the
addressee or to another participant for relay to the addressee.
