appear on all vouchers, records, custody cards, and
Material identification, particularly of portable and
installed equipment, is made easier by referring to
nameplates attached to the equipment. Nameplate data
includes the manufacturers name and the equipment
make or model number, serial number, size, voltage, and
Certain technical material may be identified only by
a drawing or sketch number. These numbers may be
assigned by the manufacturer, controlling bureau, or
systems command. When you are requisitioning
nonstandard items, be sure to include the drawing
number, if available, to aid in positive identification.
Various items of electronic equipment are identified
nomenclature (for example, AN/UYK-7[V]). They are
also identified by Navy type or model number and
manufacturers model number, as well as stock number
and serial number.
Contractors Service Bulletins
Contractors service bulletins include contractors
recommendations for modifying or repairing specific
equipment. They cover a wide range of equipment and
usually contain part numbers, nomenclature, and names
When you turn in a requisition for supplies, you set
in motion a long chain of events involving movement of
materials, maintaining stock records, and procurement
actions. Because of this chain of events, you (the
requisitioner) must supply accurate information to
ensure prompt results from the requisition.
The Management List-Navy (ML-N) and several
related publications provide you with information for
submitting accurate and error-free requisitions. The
Federal Logistics Data (FEDLOG), NAVSUP P-2002,
or the Naval Logistics Library available on compact
disk (CD), describes the format and use of these
publications. The supply department is the primary user
of these publications. However, as a division supply
petty officer, you may have an occasional need for
information contained in them. For that reason, the
following short descriptions of these publications is
Management List-Navy (ML-N)
The Management List-Navy (ML-N) is the basic
publication relating to national stock number (NSN)
management data. It is published in national item
identification number (NIIN) sequence and includes only
items for which Navy interest has been recorded.
Although it includes ammunition items, you still must
use the Catalog of Navy Ammunition Stock, NAVSEA
OD 12067/NAVAIR 11-1-116, for ordering and
reporting items of ammunition.
The ML-N omits subsistence items, such as food.
The source for subsistence items is the book edition of
the Federal Catalog for Subsistence compiled by the
Defense Personnel Support Center. The ML-N also
omits cryptographic, cryptologic, and defense nuclear
items, which are listed in security classified catalogs
produced by the respective DoD agencies.
The ML-N is a Navy-tailored publication; therefore,
many NSNs may be located in the Master Cross-
Reference List (MCRL) that will not be found in the ML-
N. If the item being researched is not found in the ML-N
(including deleted items) and a continuing requirement
exists, the using activity must take the necessary action
to establish Navy interest in procuring that item. Figure
7-3 shows the format of the ML-N. Table 7-1 lists the
contents of the ML-N.
For definitions and explanations of the various
codes used in the columns of the ML-N, refer to
FEDLOG, NAVSUP P-2002.
The Master Cross-Reference List (MCRL), Part I
(fig. 7-4), provides a cross-reference from a reference
number (manufacturers part number, drawing number,
design control number, etc.) to its assigned NSN. The
MCRL, Part II (fig. 7-5), provides a cross-reference
from an NSN to a reference number.
