(NO. CCC 11.5)

1.  Defense Planning Guidance Element.  This Mission Need Statement responds to two foundations of the National Defense Policy:  Forward Presence and Crisis Response.  The Marine Air- Ground Task Force (MAGTF) Master Plan dated 28 June 91, capability numbers 3, 17 and 30, Mission Area Analysis (MAA) 12, Intelligence, 25 March 91 deficiencies 1, 2, 4 and 8, and the Marine Corps Master Intelligence Plan document the need for this capability.

2.  Mission and Threat Analyses  

    a.  Mission.  The Marine Corps deploys MAGTFs throughout the world to meet operational commitments.  These MAGTFs access certain national level intelligence sources during peacetime, heightened hostilities and wartime to give commanders near-real-time all source intelligence and disseminate it throughout the MAGTF.  Additionally, MAGTFs require the capability to provide the necessary CINC connectivity when the Marine Corps is required to establish the nucleus of a JTF headquarters.  Commanders require secure, reliable, mobile, data and voice communications which can receive and disseminate bulk data and imagery products from national intelligence sources.  This communications network cannot be subject to terrain masking and distance limitations.  An initial operational capability of FY96 is required and a full operational capability of FY00 is desired.

    b.  Threat.  Threat forces may attempt to adversely affect, degrade or deny use of selected portions of the radio frequency spectrum through the use of electronic warfare (EW) (including detection and location of radio transmission sources).  Radio communications may be severely degraded by nuclear or non-nuclear electro-magnetic pulses.  Terminals could be targeted for physical destruction.  Furthermore, directed energy weapons (laser, radio frequency and particle beam) will assist in performing the EW function of jamming, degrading and destroying critical U.S. control of elements.  A classified threat assessment to satellite communications systems is found in the System Threat Assessment Report for Satellite Systems (NAVMIC TA#08-92 SECRET/NONFORN).
3.  Nonmateriel Alternatives.  This requirement is driven
by the necessity to enhance the digital communications backbone in support of the intelligence requirements of the MAGTF.  In the single channel mode, there is a requirement to transmit and receive 1.544 MBS voice or data signals external to the MAGTF and 16.2 to 2.4 MBS internal to the MAGTF.  The resolution of this digital communications requirement is a material requirement.  There are no changes in doctrine, tactics, organization, or training that will provide this capability to the Marine Corps.
4.  Potential Materiel Alternative

    a.  A joint nondevelopmental solution could be sought to meet this requirement.
    b.  The Marine Corps could adopt the U.S. Army's TROJAN SPIRIT.
5. Constraints

   a.  Mobility and Transportation.  Terminal equipment with supporting antenna and power source will be mountable transportable within a two HMMWV configuration.

   b.  Manpower.  Terminals will be employed in the Fleet Marine Force (FMF) without the requirement for additional personnel nor the requirement for new or additional military occupational specialties (MOS).  Terminals will be operated by the field radio operator (MOS 2531) and maintained by the ground radio repaired (MOS 2841) or radio technician (MOS 2861).   

   c.  Operational Environment
       (1) Organizational Concept.  Terminal equipment will be employed at the MAGTF Command Element (CE) and within its major subordinate commands.

       (2) Performance Characteristics.  Terminal equipment will have the following capabilities:
           (a) capable of providing digital and voice communications at the standard T1 trunk levels (1.544 MBS United States rate and 2.048 MBS European rate) for commercial interface.
           (b) capable of subdividing the individual subscribers and digital switchboards at 16 kbps/32 kbps data rates using remote multiplexer combiners or similar devices.  Larger trunk group rates using digital group multiplexer equipment is desired.

           (c) capable of transmitting within the C-band, X-band, and Ku-band.

           (d) capable of being roll-on and roll-off with C-130 or larger aircraft.

           (e) capable of being externally lifted by a CH-53E.

           (f) capable of having a primary power source of Marine Corps inventory generators.            
           (g) capable of remote operation.
           (h) capable of using built-in test (BIT) diagnostics or prognostics that will fault isolate to a single line replacement unit (LRU).

           (i) capable of having integrated terminal
TRANSEC and capable of Over-The-Air Rekey (OTAR).
           (j) capable of not being controlled as COMSEC items.
           (k) capable of providing satellite communications
service between 70 degrees North and South Latitudes.
           (l) capable of exercising strict control over
transceiver to maintain compliance with Emission Control (EMCON)
           (m) capable of providing surge protection and
uninterrupted power supply during power fluctuations.
           (n) capable of accessing Defense Data Network (DDN), electronic-mail (e-mail) and non-tactical ADP networks, allowing for future access to classified data network.
           (o) capable to vehicle mount the SHF terminal in a high mobility multi-purpose wheeled vehicle (HMMWV) and to communicate while on the move.
           (p) capable of being powered by an internal battery source, both rechargeable and nonrechargeable, with a desired capability of using adaptable power conversion/filter devices; batteries must be standard within DoD and approved for air transportation.
           (q) capable of providing warning of low battery
power to the operator.
           (r) capable of being operationally remoted through a user-provided input/output device.
           (s) capable of being resistant to enemy electronic warfare (EW).

       (3) Weather and Terrain.  Terminal equipment will be employed in all environmental and weather conditions to include, but not limited to: tropical, desert, temperate, arctic, maritime, forest, jungle, rain, snow, sleet, fog, dust, and sand.

       (4) Nuclear Biological and Chemical.  There is no requirement for this system to be nuclear hardened; although, there is a requirement for this equipment to be functional in a chemical or biological environment.  Furthermore, it is required for Marines to operate this terminal equipment while wearing Mission Oriented Protective Posture (MOPP) gear.    

   d.  Training.  Initial fielding will be supported by new equipment training teams (NETT).  Formal school training of operators/maintainers will be determined at a later date.  Single channel terminal operator training at the Marine Corps Communications-Electronics School, Field Radio Operator Course is desired.

   e.  Logistics.  Maintenance support will be established with the Marine Corps organic levels of maintenance.  Depot maintenance will be determined at a future date by the assigned program manager, but Service agreement with the U.S. Army for depot support may be desired.
   f.  Command, Control, Communications and Intelligence Interfaces.  The terminal equipment must meet all DoD interoperability standards and interface with all other Services and Agencies throughout the DoD.
   g.  Security and Standardization.  Users of these SHF
satellite terminals will be able to pass communications traffic of any security level.

   h.  Mapping, Charting and Geodesy Support.  None applicable.
