MISSION NEED STATEMENT (MNS)                                         FOR THE
            TECHNICAL CONTROL AND ANALYSIS CENTER (TCAC)     PRODUCT IMPROVEMENT PROGRAM (PIP)                                                      (NO. INT 1.31)

1.  Defense Planning Guidance Element.  This mission need statement (MNS) responds to the four foundations of National Defense Policy:  Strategic Deterrence; Forward Presence; Crisis Response; and Reconstitution.  The TCAC PIP is applicable to Mission Area 12 (Intelligence) and is documented in capabilities 3, 6, 11, 17, 38, and 43 of the Marine Air-Ground Task Force (MAGTF) Master Plan (MMP) of 28 June 1991.
2.  Mission and Threat Analyses

    a.  Mission.  The Marine Corps deploys MAGTFs throughout the world which must be prepared to fight across the spectrum of conflict.  Tactical Signals Intelligence (SIGINT) operations  provide the MAGTFs with a lucrative source of information for indications/warning, and intelligence information.  The Fleet Marine Force (FMF) Radio Battalions possess an extensive capability for collection of SIGINT against potential MAGTF adversaries.  The TCAC PIP complements deficiency 1, 2, 4, 5, 8, and 10 listed in Table One of Mission Area Analysis (MAA) 12 for Intelligence and will provide a highly improved, organic capability for tailored, fused intelligence reporting to the MAGTF.  The current TCAC system is obsolete.  It does not provide automated data processing capabilities, cannot interface with and receive near-real-time data from national/theater intelligence platforms, and lacks the capability to report time sensitive indications and warning information to the MAGTF.  Finally, it lacks the capability to process, analyze and report collected information in a near-real-time basis to the supported MAGTFs.
    b.  Threat.  The current Marine Corps Mid-Range Threat Estimate of 18 October 1991 addresses global threat projection and the technical threat for the next decade.  The worldwide electronic warfare (EW) threat to TCAC remote operations is documented in the Defense Intelligence Agency classified technical publications DST-1730H-018 and DST-1730H-077.  The TCAC PIP will comply with the security standards and guidelines established in Defense Intelligence Agency Manual (DIAM) 50-4.  No threat has been identified that is specifically targeted against the TCAC system; however, the system's communications links will be vulnerable to electronic warfare jamming devices.  Intercept and jamming of reporting frequencies should be anticipated.  Operators could encounter the full range of battlefield threats, to include standoff weapons, air delivered ordnance, and NBC attack.

3.  Nonmateriel alternatives.  MAA 12 indicates that changes in doctrine, tactics, organization or training will not provide this capability to the Marine Corps.

4.  Potential Materiel Alternatives  

    a.  Product improve the current system.

    b.  Nondevelopmental items (NDI).  The following systems are currently available or under development which, with certain software application changes, could perform some TCAC functions:

        (1) The U.S. Army All Source Analysis System (ASAS).

        (2) The U.S. Army Ground Based Common Sensor (GBCS).

    c.  Initiate research and development efforts to field a new TCAC system.

5.  Constraints

    a.  Mobility.  The TCAC PIP will have the capability for  installation in a High Mobility Multipurpose Wheeled Vehicle mounted shelter with self-contained power sources.  When in garrison and in the field, the system can be dismounted from the vehicle and operated in a stationary location.

    b.  Transportation.  The system must be configured to allow transport by all fixed and rotary transport aircraft. Further,  the system must be capable of mounting and movement on wheeled vehicles.

    c.  Manpower.  The requirements to operate and maintain the TCAC PIP will not be impacted by this product improvement.  The system will be operated by Marines already assigned to the Radio Battalions.  No personnel increases will be required when this product improvement is fielded.  The current and future density of Radio Battalion Signals Intelligence analysts will complement the manning of this system.  

    d.  Reliability, availability, and maintainability.  The preliminary system readiness objective is an operational availability of 0.93.

    e.  Operational environment

        (1) Organizational concept.  The TCAC PIP will be employed and supported by the FMF Radio Battalions.  Proposed fielding includes replacement of the existing three systems in each Radio Battalion through procurement of six TCAC PIP systems.  

        (2) Performance characteristics.  The system will be
capable of processing, analyzing, and disseminating Signals Intelligence information to the MAGTF.  An open system
architecture will be used to allow for capabilities enhancements   and interoperability with future systems.

    f.  Training.  New equipment training will be accomplished prior to delivery to the using units.  Training requirements for the TCAC PIP will be supported within the current training system with minimal additional training provided to supervisors and managers of the TCAC system.  Training for maintenance personnel will be conducted within existing manpower constraints.  Technical documentation, extension training materials, literature, publications, and other training products will be developed and fielded with the system.

    g.  Logistics.  Existing logistics support programs will be
used for system support.  Dependence on non-military organizations for supply/repair is not desired.

    h.  C4I interfaces.  The TCAC PIP will achieve interoperability with MAGTF elements through digital data links and secure voice communications, compatible with existing and planned systems.  The TCAC PIP will possess accredited security capabilities for the handling of Special Compartmented Information (SCI) data.

    i.  Standardization and interoperability.  The system will conform to the standards contained in the Government Open System Interconnection Profile (GOSIP).  The system must be capable of interoperating with the Radio Battalions' current and planned collection, analysis/processing, and communications equipment.  The system must also be capable of communications with other Service tactical, ground based, afloat, and airborne intelligence collection systems.
