                TSEC/KG-84C
            (2) TSEC/KG-84() Allowance List
            (3) RGQ-84()/TSEC Allowance List

    1.  Purpose.  To disseminate logistics information pertaining to the General
    Purpose Encryption Equipment, TSEC/KG-84A and General Purpose Telegraphy
    Encryption Equipment, TSEC/KG-84C.

    2.  Background.  The KG-84 family of equipment is a series of general purpose
    cryptographic devices intended to replace existing, aging equipment and satisfy
    emerging secure communications requirements. These devices are general, high
    capacity key generators used to encrypt and decrypt teletypewriter and digital
    data in both tactical and fixed plant environments. The TSEC/KG-84A was designed
    to provide enhanced encryption equipment to support the TRI-TAC switched
    network. The TSEC/KG-84C demonstrates significant enhancements over the TSEC/KG-
    84A,  particularly an improved high frequency capability, but remains
    cryptographically compatible with the TSEC/KG-84, TSEC/KG-84A and TSEC/KG-82.
    The TSEC/KG-84A and TSEC/KG-84C will be referred to as the KG-84() throughout
    the remainder of this Order.

    3.  Information

        a.  New Equipment

            (1)  The KG-84() provides significant improvements in reliability, key
    variable distribution, and security over existing equipments. The incorporation
    of large-scale integration (LSI) technology allows the KG-84() to realize a
    substantial reduction in size, weight, and power consumption requirements.

    MCO 2040.8
    7 Nov 1988

            (2)  The KG-84() accepts plain-text digital data from various
    input/output (I/0) devices or data adapters in either full duplex, half duplex,
    or simplex modes of operation. Input data may be a continuous bit stream
    synchronized at various clock frequencies ranging from 50 bits per second (b/s)
    to 32,000 b/s or asynchronous data in specified formats at various stepping
    rates from 50 b/s to 9,600 b/s. An optional mode timing system allows a choice
    of operating from either an internal or external clock source. The external
    clock option allows operation at any arbitrary data rate up to 64,000 b/s. The
    KG-84() encrypts the plain-text data and performs additional processing
    operations, such as diphase modulation, if required by system configuration to
    produce cipher-text information optimized for transmission to, the interfacing
    external equipment. Conversely, the X  84() accepts incoming cipher-text data,
    decrypts the data, and performs other processing operations to recover the
    plain-text data or message. The resulting plain-text information is sent to a
    compatible I/O device or data adapter.

            (3)  A complete replacement set of KG-84() printed wire assemblies
    (PWA's) will be contained in the RGQ-84()/TSEC PWA spares kits. The components
    of the RGQ-84A/TSEC and RGQ-84C/TSEC kits are listed in enclosure (1).

        b.  Replaced Items. The KG-84() will replace the TSEC/KW-7, TAMCN A8016,
           TSEC/-26C, A8017, TSEC/KG-13, TAMCN A8022, TSEC/KG-30, TAMCN A8040,
    TSEC/KG-33, TAMCN A8041, and TSEC/KG-34, TAMCN A8037 equipment. Disposition
    instructions for replaced equipment should be requested from the Director,
    Communication Security (COMSEC) Material System (DCMS) per reference (a).

        c.  Supported Systems. The KG-84() will be employed with the
    following communications systems. The respective KG-84() model
    and quantity requirements will be addressed in the appropriate
    systems documents.

    under development the respective contractor will provide for KG-84()
    installation requirements.  The Marine Corps is responsible for KG-84()
    installations in support of all fielded tactical systems.  Modification
    instructions will be developed and ancillary components will be made available
    to facilitate these tactical system installations.

        d.  Training

            (1)  Operator Training

                 (a)  Formal Training.  No specific Military Occupational Specialty
    (MOS) has been designated for the KG-84() operator. The KG-84() has application
    to the operator MOS's connected with the communications, communications center
    and command and control equipment listed in paragraph 3c, preceding. Formal
    operator training will be limited to orientation and familiarization with KG-
    84() equipment at the Marine Corps Communication - Electronics School (MCCES),
    Twentynine Palms, California, for MOS's 2549 (Communication Center Chief) and
    2591 (Operational Communication Chief) and the Communications Officer School,
    Marine Corps Combat Development Center (MCCDC), Quantico, Virginia.

                 (b) Unit Training.  Operator training at the unit level will
    consist of on-the-job training using the operator's manuals available to each
    unit receiving KG-84() equipment. Each command will be responsible for
    maintaining an adequate level of qualified operator personnel.

            (2)  Maintenance Training

                 (a)  Formal

                      1  Initial Training. Initial KG-84() maintenance training
    will be provided by the Navy Cryptological Technical Maintenance School, Mare
    Island, California, and the Technical Training Center, Lackland Air Force Base,

                                                                        MCO 2040.8
                                                                        7 Nov 1988

                 (b)  Unit Training. On-the-job training at the unit level will
    supplement and reinforce the formal training received by maintenance personnel.
    Each command will be responsible for maintaining the proficiency and
    certification of maintenance personnel.

            (3)  Training Support. Training publications and programs of instruction
    will comply with current Marine Corps Orders pertaining to training standards.
    No correspondence courses are currently planned for the KG-84(). No new
    construction at the training facilities is required.

        e.  Support and Test Equipment. Support and test equipment requirements are
    addressed in enclosure (1).

        f.  Supply Support. The limited maintenance RGQ-84()/TSEC PWA spares kits
    will be force-fed to the supporting intermediate maintenance facilities.
    Replacement PWA's will be obtained from the Ships Parts Control Center,
    Mechanicsburg, Pennsylvania, per reference (b). Consumable repair parts will
    be obtained from the supply system per reference (b).

        g.  Maintenance Support

            (1)  General.  The modular construction and high reliability
    demonstrated by the KG-84() allow a maintenance concept that minimizes the
    degree of maintenance to be performed at the organizational and intermediate
    levels and concentrates major repair work at the depot level.

            (2)  Organizational Level Maintenance. Maintenance performed at the
    organizational level will be preventive in nature and will include the cleaning,
    inspecting, and operational testing of the KG-84() equipment. Defective KG-
    84() end items will be evacuated to the supporting Force Logistic Support
    Cryptographic Facility (FLSCF) or Support Cryptographic Site (SCS) for
    corrective maintenance as described in reference (b).

            (3)  Intermediate Level Maintenance. Only personnel who have graduated
    from an approved KG-84() maintenance training course are permitted to perform
    limited maintenance on KG-84() equipment. Maintenance performed at the
    intermediate level will be limited to fault isolation to the PWA level and the
    removal and replacement of defective PWA's and mechanical parts. Spare PWA's
    will be available in the RGQ-84() maintenance kits prepositioned at the FLSCF's
    and SCS's. End item exchange pool assets will be provided to the operational
    readiness float (ORF) established at the force service support group (FSSG)
    within each Marine expeditionary force (MEF) and at the Brigade Service

                                     5
    MCO 2040.8
    7 Nov 1988

    Support Group (BSSG) within the lst Marine Expeditionary Brigade (MEB). These
    assets will be reflected under the appropriate ORF's table of equipment (T/E)
    but will be controlled by the respective intermediate maintenance activity.

            (4)  Depot Level Maintenance. Defective PWA's and KG-84() end items not
    repairable at the intermediate level will be evacuated to the supporting Naval
    Cryptographic Repair Facility (CRF) through the FLSCF as described in reference
    (b).

        h.  Controlled Cryptographic Item Management

            (1)  Classification and Accountability. Unkeyed KG-84() equipment and
    components have been classified as Controlled Cryptographic Items (CCI). CCI
    items are unclassified but remain under the control of DCMS. The KG-84() end
    items and RGQ-84() PWA spares kits will be centrally accounted for at DCMS by
    serial number per reference (a). Keyed CCI equipment assumes a classification
    level equal to that of the keying material and will be safeguarded per the
    provisions of reference (c).

            (2)  Transportation.  CCI equipment and components may be transported
    only by traceable means. Authorized transportation media are: Defense Courier
    Service, State Department Diplomatic Courier Service, Officially Designated
    Command Couriers, U.S. registered mail (provided that it never passes out of
    U.S. control or through a foreign postal system or any foreign inspection), and
    military or commercial transportation systems with strict accountability
    provided by the Department of Defense Constant Surveillance System (DoD CSS).
    In foreign countries where there is a significant U.S. military presence (two
    or more military bases where U.S. military personnel are stationed), foreign
    nationals who are employed by the U.S. Government may transport CCI material,
    provided there  is a signature record from the pick-up location to the ultimate
    destination and a U.S. citizen accompanies the foreign employee in couriering
    the material or the material is contained in a closed vehicle or shipping
    container (conex, dromedary) which is locked and has a shipping seal. A
    completed SF-153 (COMSEC Material Report) must accompany each item during any
    transfer of KG-84() equipment. Shipment of CCI material must always be made
    with a DD-1149 (Requisition and Invoice/Shipping Document) attached to the
    outside container. The KG-84() will be zeroized prior to shipment and will be
    shipped separately from its keying material.

            (3)  Access.  A security clearance is not required for viewing of or
    access to unkeyed KG-84() equipment and components. Access shall be restricted
    to U.S. citizens whose duties require such access. Access may also be granted
    to permanently admitted resident aliens, who  are either U.S. Government
    civilian employees, active duty military or Reserve members of the U.S. Armed
    Forces, whose duties require access.

            (4)  Storage.  Unkeyed KG-84() equipment and components must be stored
    in a manner that affords a level of protection at least equal to that normally
    provided to high value or sensitive material. Classified keying material,
    classified supporting documents and keyed KG-84() equipment must be stored per
    the procedures outlined in reference (c).

                                                                     MCO 2040.8
                                                                     7 Nov 1988

        i.  Replacement Factors.  Replacement factors will not apply.

        j.  Technical Representatives. Contractor technical representatives will
    not be provided. Technical assistance, as required, may be obtained from the
    National Security Agency (NSA), the Naval Electronic Systems Security
    Engineering Center (NESSEC) or other agencies by requests to the Commanding
    General (CG), Marine Corps Research, Development and Acquisition Command
    (MCRDAC) (C2CT).

    4.  Concept of Implementation

        a.  Initial Fielding.  (KG-84() and RGQ-84() equipment will be force-fed
    by DCMS to the Marine Corps units indicated in enclosures (2) and (3) as
    directed by the CMC (CCT). Fielding quantities of the KG-84A and KG-84C models
    will be determined by the respective operational requirements of the supported
    systems delineated in paragraph 3c, preceding. Fielding of KG-84A and RGQ-84A
    equipment has begun. KG-84C equipment will be fielded beginning lst quarter FY
    1989. RGQ-84C kits will be available beginning 3d quarter FY 1989.

        b.  Initiating Service.  Upon receipt, equipment may be placed on
    administrative deadline until the requirements of reference (d) have been
    satisfied. CG Fleet Marine Force (FMF) Pacific, CG FMF Atlantic, Base and 4th
    Division Wing Team (DWT) Commanders are authorized to place the equipment in
    service at their discretion. Strapping of the KG-84() for application dependent
    operation can be performed by a TEMPEST trained COMSEC technician using the
    respective limited maintenance manual.

    5.  Reserve Applicability.  This Order is applicable to the Marine Corps
    Reserve.

        c. Remote Control Unit. The C-11828/U Remote Control Unit (RCU), P/N ON363501-501, was
    designed for use with the KG-84() family of equipment. The RCU provides the capability to remote
    front panel controls and indicator status displays up to 1,OOO feet from the installed KG-
    84() equipment. A Remote Indicator Unit (RIU) has been developed by the NESSEC for shore
    applications where the full capabilities of the C-11828/U are not required.

        d.  Fill Devices. The common fill devices; the General Purpose Tape Reader, KYK-13/TSEC,
    the Electronic Transfer Device, KYX-15/TSEC, the Net Control Device, KOI-18/TSEC, and the Data
    Transfer Device, CYZ-10/TSEC will be used to store and load cryptovariables to the KG-84(). The
    KG-84() also has a remote keying capability.

        e.  Cables. The following cables have been identified for use with the KG-84():

    These cables may be obtained by submitting the appropriate requisition through the supply
    system. CG MCRDAC (C2CT) is in the process of developing a technical instruction which will
    provide instructions on how to manufacture these cables as well as a UGC-74/KG-84A interface
    cable.

        f.  Mounts.  The standard shore shelf installation will use the fixed plant adapter (FPA),
    NSN 5895-01-251-9506. The standard shipboard installation will use the MT-4841/U with KG-84
    backplane, NSN 5820-01-069-1881. Mount requirements for KG-84() installation in fielded systems
    will be addressed in the respective modification instruction. These mounts will provide for
    mounting and interface of two KG-84() devices. Mount requirements will be addressed by the
    respective modification instructions.

        g.  Transit Case. The Transit Case, NSN 5810-01-096-7673, can be used to transport the KG-
    84().

        h.  Internal Modem.  Both the KG-84A and KG-84C have a built in wireline modem capability.
    In addition, there are two optional modems that may be installed internal to the KG-84A but not
    the KG-84C. These are the frequency shift key modem, PWA E-ENK, NSN 5810-01-150-5035, and the
    Type 1 modem, PWA E-EWW, NSN 5810-01-150-5036. Either of these modems can be installed in the
    KG-84A by swapping the respective modem PWA with the black I/O PWA. Detailed installation
    instructions are included in the respective maintenance manual. These modems will be available
    in fiscal year 1990.

        i.  Augmentation Package. The KG-84C augmentation package J-4691/S will facilitate
    replacement of installed KW-7 cryptographic equipment with KG-84C equipment. The J-4691/S
    provides for interface and signal level conversion requirements between existing equipment and
    the KG-84C equipment. Augmentation package requirements will be addressed in the modification
    instructions being developed for the AN/TGC-46 and AN/TGC-37.

                                                                  ENCLOSURE (1)
