Mystic Star Freqs


The mission of the Mystic Star system is to provide high quality voice and data communications support. You might think that this is no different from the support provided by any other communications system, but it is. The Mystic Star system supports the communications needs of the President, Vice President, Cabinet Members, Foreign Heads of State, and other senior government and military officials while aboard Special Air Mission (SAM), VIP, or Command aircraft. These aircraft are assigned an access priority based on the type of mission and agency supported. There are four access priorities used with priority one missions having the highest priority.


This designation is afforded to the President of the United States during all Air Force One flights. It is also afforded to the Vice President during Air Force Two flights if the President is not flying. Requests for circuit activation are received from the White House Communications Agency (WHCA).


This designation is afforded to those missions activated in support of high government officials requiring continuous uninterrupted access to their departmental headquarters. It is normally limited to support of the Vice President (if the President is being supported at the same time), Secretary of Defense, Secretary of State, and the Office of the Joint Chiefs of Staff (OJCS). Requests for circuit activation are received from the Department of the Air Force or WHCA.


The President, Vice President, Secretary of State, Secretary of Defense, and Office of the Joint Chiefs of Staff are the "TOP FIVE."


This designation is afforded to those missions activated for routine activities involving the National Emergency Airborne Command Post (NEACP) and other special missions as directed by OJCS. Requests for circuit activation are received from OJCS.


This designation is afforded to high government or military officials aboard SAM or other special air mission aircraft, call sign SPAR. These individuals do not require continuous, uninterrupted access to their departmental headquarters. Missions supporting Cabinet Staff members, Congress, and DOD personnel are assigned this priority. Requests for circuit activation are received from the 89th Military Airlift Wing (MAW) at Andrews AFB. The NCS at Andrews will directly support all missions. Priority four missions may be referred to Global Command and Control System (GCCS) stations. This is only if the traffic load is such that Andrews cannot provide effective support. The shift supervisor will make this decision. The operator performing coordinator duties will contact the desired GCCS station to be sure the proper support is available.


Control of the entire Mystic Star network is the function of the Net Control Station (NCS) at Andrews. This includes all HF radio and UHF SATCOM equipment and the associated voice and data circuits. The Mystic Star Communications Management System is a computer controlled electronic switching system.

The MSCMS is comprised of 13 computer equipped consoles. Two computer data base/data communication (DB/DC) modules, primary and backup, are available to each operator. Two color graphics processors provide color graphics support. Two digital switching systems provide interconnectivity within the system. Communications Security (COMSEC) equipment, voice and data modems, and data terminals are available for providing secure communications support. A voice recorder/reproducer allows for the recording of all voice transmissions. A frequency management system, time generating and synchronizing unit, and a maintenance patching facility are the final subsystems that make up the MSCMS.

The equipment subsystems that make up the MSCMS are configured for secure or non-secure operations through a Local Area Network (LAN). The LAN connects all of the equipment within the station. You cannot see the LAN working, but you use it for the distribution of command and control processing functions.


The Mystic Star system consists of eight primary and nine secondary HF radio stations located throughout the world. Each primary station provides four radio levels dedicated for Mystic Star use. Secondary stations provide at least one radio level dedicated for use by Mystic Star. A radio level consists of a transmitter, a receiver, and the associated equipment. A typical primary station consists of a Communications Relay Center (CRC), a transmitter site, and a receiver site. These are connected by transmission lines (buried cable) or microwave transmissions. The CRC consists of consoles, switches, and associated common control equipment.

The eight primary Mystic Star HF stations


The nine secondary Mystic Star HF stations
and the number of dedicated radio levels each provides are:

Andersen 1
Lajes 1
Albrook 0
Loring 1
Ascension 1
MacDill 1
Elmendorf 1
Thule 0
Incirlik 2

All stations except for Andrews, MacDill, Loring, Salinas, and Scott are GCCS stations. GCCS stations have additional radio levels and operators available if required. The stations at Albrook and Thule are secondary stations when they are activated. They have no dedicated connectivity to the NCS at Andrews. Coordination by telephone with these stations is required to obtain the radio levels you require. The Incirlik station has yet to be brought on-line and is not available at this time.

Satellite communications are provided through Ultra High Frequency (UHF) Remote Switching Units (RSUs). The RSU is a UHF radio satellite ground entry point (GEP) station for the MSCMS. There are four RSU sites that provide the Mystic Star system with global UHF satellite coverage.

The four dedicated UHF stations:
Brandywine, MD
San Vito, IT
Clark, RP
Wahiawa, HI

Each of these stations, except for Brandywine, has four dedicated radio levels; two wideband channels and two narrowband channels. The Brandywine station has six dedicated radio levels; four wideband channels and four narrowband channels for Mystic Star support.

Satellite communications are under the control of the Master Control Center (MCC) at Offutt AFB, NE. The MCC has delegated its controlling authority to several Primary Control Centers (PCCs). Working within the Mystic Star system, and coordinated with the PCCs located at Brandywine, March AFB, CA; and Kadena AB, Japan.

Brandywine is the PCC for the 23-degree west and Lincoln Experimental Satellite (LES).

March is the PCC for the 100-degree west satellite.

Kadena controls the access to the 72- and 172-degree east satellites.
