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

        (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.

    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

                                                                    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

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).

    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():

        Nomenclature                          NSN

    24 Vdc Power Cable                  5995-01-097-7556

    UXC-7/KG-84A Interface Cable        5995-01-213-9648

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.
