1. Purpose. To disseminate logistics information pertaining
to the introduction of the BANCROFT communication security
(COMSEC) equipment TSEC/KY-67 and TSEC/KY-67A; secure
transceivers, and ancillary devices, and to provide
instructions for placing these equipments in service.

2. Background

a. The BANCROFT TSEC/KY-67 and TSEC/KY-67A secure
transceivers are half-duplex, integrated, tactical, voice
security radios. They are fully compatible in cipher text (CT)
operation with the VINSON family of COMSEC equipment. They are
compatible in plain text (PT) with other VHF/FM radio equipment
operating over the 30 to 76 MHz range. The TSEC/KY-67A model
will eventually replace the TSEC/KY-67. Hereinafter, the
TSEC/KY-67 and the TSEC/KY-67A will both be referred to as
KY-67, except where specific differences exist.


PCN 102 027121 00




b. The KY-67 secure transceiver has been designed using
modular, microminiature, solid state techniques to be a rugged,
lightweight, all environment, vehicular-mounted radio. In
addition, the KY-67 features automatic resynochronization,
automatic antenna matching, and the capability of transmitting
digital data at 16 kilo bits per second (kbps).

3. Information

a. General. The KY-67 is an integrated COMSEC, secure
voice, VHF/FM transceiver. It functions as an automatic
point-to-point net radio. The KY-67 operates over the 30 to 76
MHz frequency range. The BANCROFT and NESTOR (TSEC/KY-28 and
TSEC/KY-38) equipments are incompatible.

b. New Equipment. The BANCROFT family of COMSEC
equipment consists of the major components; the KY-67 Secure
Transceiver, the HYP-67/TSEC Vehicular Amplifier-Power Adapter,
and the RYQ-67/TSEC Spares Kit. The HYP-67A/TSEC and
RYQ-67A/TSEC will be referred to as HYP-67/TSEC and RYQ-67A/TSEC
respectively, except where specific differences between models
exist.

(1) Secure Transceiver, TSEC/KY-67. The KY-67 is
capable of storing five crypto-variables and a rekeying
variable. It is a lightweight, rugged, all environment,
vehicular mounted radio. The HYP-67/TSEC is the vehicular
amplifier-power adapter for the KY-67. A small fill battery
(BA-1372) is required for crypto variable retention when the
KY-67 has been turned off or the primary power source is
removed.

(2) Vehicular Amplifier-Power Adapter, HYP-67/TSEC.
The HYP-67/TSEC (hereinafter referred to as the HYP-67), is the
primary power source for the KY-67. It provides TEMPEST and
EMI filtering, as well as providing a mechanical connection
with which to adapt a vehicular power source to the KY-67. The
HYP-67 provides the necessary interfacing of the KY-67 (mounted
in a shock mount, MT-1029/VRC), with vehicular power, intercom,
remote frequency selector control (C-2742/VRC), antenna
control, and antenna RF connections.

(3) TSEC/KY-67 Printed Wire Assemblies (PWA's). The
PWA spares kit, RYQ-67/TSEC (hereinafter referred to as the
RYQ-67), contains a complete set of KY-67 and HYP-67
replacement plug-in modules. These replacement modules may be
used by a qualified repairer during the testing and/or
troubleshooting of a KY-67 or HYP-67 and may be used to repair
a defective KY-67 or HYP-67. The contents of each RYQ-67 kit
are listed in enclosure (1).


2


c. Associated Equipment

(1) Used in conjunction with a KY-67 to provide,
store, and/or generate cryptovariables (key) for the KY-67, is
the family of common fill devices; General Purpose Tape Reader
KOI-18, Electronic Transfer Device KYK-13, and the Net Control
Device KYX-15. Reference (a) provides logistics information
for keying devices.

(2) The KY-67 is designed to be mounted in the
existing MT-1029/VRC shock mount.

d. Replacement Equipments. The BANCROFT COMSEC system
(KY-67, HYP-67, and RYQ-67) will provide tracked and Light
Armored Vehicles (LAV's) secure VHF/FM communications. The
BANCROFT KY-67A will replace the BANCROFT KY-67.

e. Concept of Implementation. Initially, the fielding of
the BANCROFT KY-67 will be accomplished simultaneously with the
fielding of the LAV and its supporting establishments.
Fielding of the KY-67, to other than LAV and LAV support
activities, will commence subsequent to the scheduled December
1985 deliveries from the Navy follow-on competitive con-tract.
Enclosure (2) contains logistics planning data for the BANCROFT
equipment. Allowances for the BANCROFT equipment are listed in
enclosure (3).

f. Training

(1) Initial Training To Place Equipment In Service

(a) Operator Training

1 Personnel Assigned to Training
Institutions. In the case of the BANCROFT KY-67 equipment, no
specific military occupational specialty (MOS) has been
designated as operator. Currently, the BANCROFT System has
application to those MOS's connected with the LAV, Amphibious
Assault Vehicle (AAV), and Tanks. Operation of the BANCROFT
System is thought to be elementary, such that formal training
of instructors at the Infantry Training Schools (ITS's) at Camp
Lejeune and Camp Pendleton; Schools Battalion, Camp Pendleton,
and the Marine Corps Communication-Electronics (MCCES),
Twentynine Palms, is not required. Only a familiarization of
equipment at the formal schools in conjunction with an
operator's manual is necessary for adequate training.

2 Personnel Assigned to Units. Fielding is
currently underway and personnel are acquiring operator
training via on-the-job training (OJT), aided by the operator
manual shipped each system.

(b) Maintenance Training

1 Personnel Assigned to Training Institutions.
The Marine Corps has no requirement for BANCROFT KY-67 or
KY-67A System factory training for maintenance instructors.

2 Personnel Assigned to Units. Fielding of
future BANCROFT KY-67 equipment will progress commensurate with
adequate maintainer staffing within the appropriate maintainer
unit/command.

(c) Other Training. Factory maintenance training
for the KY-67A will be conducted in the first quarter of fiscal
year (KY) 1986.

(2) Follow-On Training

(a) Operator Training

1 Formal Schools. There are no formal school
operator training requirements, other than an orientation/
familiarization with the BANCROFT KY-67 System, as provided in
MOS's 2537 (Radio Chiefs) and MOS 2591 (Operational
Communication Chiefs) courses at MCCES, Twentynine Palms, and the
Communications Officers courses at the Communications Officer's
School (COS), Marine Corps Development and Education Center
(MCDEC), Quantico.

2 Unit Training. All operator training at
the unit level during and after initial fielding will consist
of OJT, using the operator manual provided with each piece of
equipment. Each command will be responsible to maintain an
adequate level of qualified operator personnel.

(b) Maintenance Training

1 Formal School. Keesler Air Force Base
(AFB), Mississippi, will train KY-67 maintenance personnel
beginning in the fourth quarter of FY 1985. The U.S. Navy will
train appropriate KY-67A maintenance personnel at the
crytographic repair facilities (CRF's), in either Norfolk,
Virginia or San Diego, California. This training will be for
MOS 2881 (Communication Security Equipment Technician) and,
alternately, MOS's 2841 (Ground Radio Repairer) and 2861 (Radio
Technician). Personnel trained at the CRF's should become
available during the first quarter of calendar year (CY) 1986.

2 Unit Training. Unit OJT will serve to
supplement formal training for maintainers. The maintainers'
level of proficiency and certification will be the
responsibility of the unit/command.

and intermediate maintenance consumable repair parts (i.e.,
knobs, screws, etc.), will be obtained from the item manager
(Naval Telecommunications Command) in accordance with either
reference (d) or (e).

(2) Secondary reparable (SECREP) parts supply support
is provided by Ship Parts Control Center (SPCC) in accordance
with references (b) and (f). The COMSEC SECREP parts are
multilayered/microminiature circuit boards/plug-in
subassemblies which are reparable. Support stocks of SECREPS
are considered adequate for initial issue of the BANCROFT
system.

i. Transportation, Handling, and Accounting

(1) Transportation and accounting will be in
accordance with reference (g). Additional accounting of these
equipments will be in accordance with references (d) and (e).

(2) Handling and Physical Security

(a) Access

granted to personnel whose duties require such access and who
possess appropriate clearances.

2 Access to unkeyed KY-67 and their
ancillary devices, associated testers, PWA spares kits, and
classified supporting documentation, may be granted to
personnel whose duties require such access and who possess a
confidential or higher clearance.

3 Clearances are not required for external
or cursory viewing of KY-67.


6


4 Uncleared personnel may use the KY-67
under the direct supervision of appropriately cleared
personnel. Operational nets must, however, first be alerted to
the participation of uncleared personnel.

5 Military or civilian guards and security
patrols that provide protection for locations where "UNKEYED"
KY-67's are installed (e.g., motor pools, flight lines, etc.)
need not be cleared, but shall be instructed not to handle the
COMSEC equipments.

(b) Storage

1 Classified key tapes and keyed KY-67's
must be stored as COMSEC material of the appropriate
classification in accordance with reference (g). Keyed KY-67's
installed in vehicles must be under the continuous control of
appropriately cleared personnel.

2 Unkeyed KY-67's installed in vehicles need
not be removed provided the provisions of references (g) and
(h) are satisfied.

3 Unmounted and unkeyed KY-67's, their
classified supporting documents, and separate classified PWA's
must be stored as confidential COMSEC material.

4 Unclassified key tapes marked "CRYPTO"
must be stored as classified COMSEC material or in the most
secure manner available to the user.

5 The KY-67 ancillary equipment should be
stored in a manner appropriate for valuable electronic items.

j. Replacement Factors. Replacement factors will be
determined at a later date.

k. Maintenance Support

(1) General Information. The advanced technology
employed within BANCROFT equipments in combination with its
demonstrated reliability offers a maintenance concept which
minimizes the degree of maintenance performed at the
organizational level, allows for limited maintenance at the
intermediate level, and concentrates major repair at the depot
level. To support this concept, an exchange pool program will
be established.

(2) Maintenance Qualification. Only maintenance
personnel who are qualified, as described in reference (c), may
perform maintenance support functions on the BANCROFT equipment.


7


(3) Organizational Maintenance. Organizational
maintenance will consist of cleaning, inspecting, operational
checks, and replacing, when necessary, of faulty system
components. Defective COMSEC equipment (end item) will be
evacuated to the supporting FSSG FLSCF for corrective
maintenance.

(4) Intermediate Maintenance. Intermediate level
maintenance will be performed at the FLSCF at the supporting
FSSG. The FLSCF's maintenance will be limited to the
replacement of defective PWA's and mechanical parts. Depot
maintenance of PWA's will be performed by the Navy in
accordance with references (b), (f), and (g). The RYQ-67 spare
kits positioned at the FLSCF will be used to initially provide
nonconsumable parts. An exchange pool will be established for
end items at the FSSG within each Marine Amphibious Force
(MAF). The exchange pool will be operationally equivalent to
an operational readiness float.

(5) Depot Maintenance. Defective KY-67 end items not
reparable at the FLSCF will be evacuated to the supporting
naval CRF through the FLSCF in order to establish a centralized
point of control within each MAF.

l. Retrofit and Modification Kits. Retrofit and/or
modification kits of existing vehicular radio installations
will not be necessary. The KY-67, in conjunction with the
HYP-67, has been designed to be easily installed into the
MT-1029 mount presently used with the Marine Corps.
Information addressing installation will be the subject of a
separate technical instruction (TI).

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

n. Battery Power Source. The KY-67 contains a miniature
primary 6.5-V mercuric oxide battery (BA-1372/U), which is used
to provide power for cryptovariable memory retention when the
KY-67 has been turned off or the primary power source is
removed.

(1) Mercury and its organic and inorganic compounds
may be toxic when ingested, absorbed through the skin, or
inhaled. The BA-1373/U should not be subjected to case
rupture. Under excessive heat, mercury batteries are likely to
explode and spread mercury contamination. Sufficient heat to
cause explosion may be generated by an accidental short circuit
of the battery terminals or by incineration. Care should be
exercised in using mercury batteries to prevent an accidental
short circuit.


8


(2) The BA-1372/U shall not be dumped into any body of
water, including oceans.

(3) All expended/unserviceable BA-1372/U's will be
turned in to the area Defense Property Disposal Office in
accordance with reference (i) for mercury reclamation.

4. Initial Service. The Director, Communications Security
Material System (DCMS), as guided by the CMC (CCT), will direct
shipment of the prescribed allowances of the BANCROFT
equipment. Initial distribution of the BANCROFT equipment will
be to units receiving the LAV. It is anticipated that delivery
of the BANCROFT equipments will coincide with deliveries of
the LAV. Other units will receive the BANCROFT equipment after
delivery has been completed to LAV units. The following
procedures are necessary to ensure proper distribution and
placing of BANCROFT equipments in service.

a. Upon receipt, equipment may be placed on administrative
deadline until the requirements of reference (j) have been
accomplished. Force commanders and the Commanding General, 4th
Marine Division, are authorized to place the equipment in
service at their discretion.

b. The target date for placing BANCROFT equipment in
service is the same as that of the LAV.

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