    Encl:  (1) Logistics Planning Data for the Electronic Key
               Generator, TSEC/KG-27

    1.  Purpose.  To provide advance logistics information to
    Commanders relative to the Electronic Key Generator, TSEC/KG-27
    (hereinafter referred to as the KG-27), and to provide instruc-
    tions for placing the equipment in service.

    2.  Background.  The KG-27 is full duplex equipment used to
    encrypt tactical, multichannel communication. The unit is
    designed for simplicity of installation, operation, and main-
    tenance. Within the Marine Corps, the KG-27 will be used in
    the Terminal Set, Telephone, AN/TCC-72, which is the companion
    multiplexer van to the Radio Set, AN/GRC-201, and the Ground
    Mobile Forces (GMF) Super High Frequency (SHF) Satellite Communi-
    cations Terminals, AN/TSC-85A/93A. Reference (a) is the ALO
    for the AN/TSC-85A/93A systems.

    3.  Information

        a. General. The KG-27 provides link security for low,
    medium, and high capacity Pulse Code Modulation (PCM) tactical
    radio relays of the Marine Amphibious Force (MAF). Since the
    KG-27 is a controlled telecommunication security item, it will
    be received through the Cryptographic Material System (CMS).
    It will be the using units responsibility to "marry up" the
    KG-27 with the Terminal Set, AN/TCC-72, and the Satellite
    Communications Terminal, AN/TSC-85A/93A.

        g. Supply Support. Secondary reparables  SECREP'S) will be
    force-fed to the Support Cryptographic Sites (SCS'S) as limited
    Maintenance Kits, RGQ-27. Supply support for organizational and
    intermediate maintenance consumable repair parts (knobs, screws,
    etc.) will be obtained from the item manager (Naval Telecommuni-
    cations Command) in accordance with references (b) and (c).

        h. Transportation and Handling. Transportation and handling will be in
    accordance with references (d) and (e).

           (1) Handling and Physical Security

               (a) Access. All access is subject to approval of the unit's
    commanding officer. Access to keyed KG-27 equipment may be granted to personnel
    whose duties require such access and who possess an appropriate clearance.
    Access to unkeyed KG-27's and ancillary devices; associated testers, RGQ spares
    kits, and classified supporting documentation may be granted to personnel whose
    duties require such access and who possess a confidential or higher clearance.
    Clearances are not required for external or cursory viewing of the KG-27.
    Military or civilian guards and security patrols that provide protection for
    locations where  unkeyed" KG-27's are installed (e.g., motor pools, flight
    lines, etc.) need not be cleared, but shall be instructed not to-handle the
    crypto equipment.

               (b) Storage. Classified keying equipment, and keyed KG-27's
    must be stored as communication security (COMSEC) material of the appropriate
    classification in accordance with reference (e). Keyed KG-27's must be under
    the continuous control of appropriately cleared personnel. Uninstalled KG-
    27's, classified supporting documents, and separate classified printed wiring
    assemblies  (PWA'S) must be stored as confidential COMSEC material.

        i.  Replacement Factors. Replacement factors will not apply.

        j.  Maintenance Support

            (1) General. The concept of operations for the systems in which the
    KG-27 will be employed, and the technology used in the KG-27, require a
    maintenance concept differing from other Marine Corps COMSEC equipments. The
    system maintainer for the major system in which the KG-27 is in use, will also
    maintain the KG-27. Using units will also be provided additional KG-27's to be
    used as ready spares.

            (2) Organizational Maintenance. Organizational maintenance will consist
    of cleaning, inspecting, operational checks, and the replacing of faulty
    external components (knobs, fuzes, etc.).

                                            4                                              MCO 2200.2

    spare kits positioned at the SCS'S will provide SECREP and nonconsumable parts
    support.

            (4) Depot Maintenance. Defective KG-27 end items not reparable at the
    SCS will be evacuated, via the Fleet Logistics Supported Cryptographic Facility
    (FLSCF), to the supporting Naval Cryptographic Repair Facility (CRF) in order
    to establish a centralized point of control within each MAF. Defective SECREP'S
    will be evacuated, via the FLSCF, to the Ship Parts Control Center (SPCC),
    Mechanicsburg, Pennsylvania, in accordance reference (f).

        k. Technical Representatives. Contractor technical representatives will not
    be provided. Technical assistance, as required, may be obtained from the
    National Security Agency (NSA), Naval Electronics Systems Security Engineering
    Center (NESSEC) or other.agencies by request to the Commandant of the Marine
