EXPEDIENTE SANCIONADOR N º: GC/30051/P/2008;

Navy-adopted ammunition items that have been type classified per Technical Manual TW010- AA-ORD-010/11-1-116A are officially identified

by logistical terms. This facilitates supplying the fleet. Each ammunition item is identified by an approved nomenclature, identification number, lot number, and net weight. Additionally, some items are marked with contract number, place and date of manufacture. The information is stenciled on the item, the shipping container, or both. A new iden- tification number is assigned when a basic change in design is made. A new Mod number is assigned when a minor alteration or modification is made.

1-3.1. Navy Item Identification. Ammunition

items designed and produced for the Navy are identified by Mark (Mk) and Modification (Mod). An example is Signal Cartridge Mk 121 Mod 0. A minor modification to this item results in the iden- tification being Mk 121 Mod 1.

1-3.2. Army Item Identification. When the

Navy procures ammunition items that were designed and produced for the Army, the original assigned Army identification number remains with the item; for example, Cartridge, .50 Caliber, Spot- ter/Tracer M48A1. The M corresponds to Mark, and the A1 corresponds to Mod. A minor modifi- cation to that cartridge would result in the identifi- cation being M48A2.

1-3.3. Items Without Identification Numbers.

Some ammunition items have neither Navy nor Army item identification numbers. Those items are identified by their nomenclature and drawing num- ber; for example, Cartridge, .22 Caliber, Ball, Short (10523992).

1-3.4. Standard Department of Defense Nomenclature and Numbering. A standard

nomenclature and numbering system has been established in the Department of Defense (DoD) and is mandatory for record keeping and ordering purposes. The National Stock Number (NSN) has replaced the Federal Stock Number, and there is a different NSN for each item in supply. The first four digits of the NSN are the Federal Supply Class number that groups similar type items into classes. The next two digits are the National Codification Bureau (NCB) code number that designates the North Atlantic Treaty Organization (NATO) coun- try that catalogs the item. The last seven digits combined with the NCB code number (two digits) are designated as the National Item Identification

Number (NIIN). All currently available NSN and DoD code numbers for each item or component are included in this technical manual. Appendix A, Department of Defense Identification Code/Naval Ammunition Logistic Code Index (DODIC/NALC Index), contains a numerical listing of assigned DoD codes, ammunition nomenclature, and the appropriate paragraph under which that ammuni- tion is identified. The lead DODIC/NALC number is also listed in parenthesis ( ) after each item para- graph.

1-3.5. Ammunition Lot Numbers. When

ammunition is manufactured, an ammunition lot number is assigned in accordance with specifica- tions. As an essential part of the lettering, the lot number is stamped or marked on the item, size per- mitting, as well as on all packing containers. There are presently two ammunition lot numbering sys- tems in the ammunition inventory. The newest lot numbering system was implemented by the Navy in 1978, so there is considerable ammunition inventory still identified by the old numbering sys- tem. Both systems are described in the following paragraphs.

1-3.5.1. Current Ammunition Lot Numbering System. For all ammunition end items and their

components, the ammunition lot number consists of a manufacturer’s identification symbol; a numeric code showing the year of production; an alpha code representing the month of production; a lot interfix number followed by a hyphen; a lot sequence number; and, when necessary, an alpha character used as an ammunition lot suffix to denote a reworked lot. The ammunition lot num- ber will not exceed 14 characters in length, and no characters are separated by spaces. The minimum number of characters used will be 13. If a one or two character manufacturer’s identification code is used, the remaining position(s) of the three char- acter field is filled by a dash(es) (-); e.g., AB- and A--. The following illustrates the construction of an ammunition lot number:

WCC85E001-004B

WCC = Manufacturer’s identification symbol 85 = A two digit numeric code identifying the year of production (1985)

E = A single alpha code signifying the month of production (May)

001 = Lot interfix number 004 = Lot sequence number

B = Ammunition lot suffix (the alpha suf- fix).

Exceptions to the foregoing system for numbering ammunition lots are given in MIL- STD-1168, Section 5.

1-3.5.2. Old Ammunition Lot Numbering System. This numbering system consists of the

Ammunition Lot Number (ALN) symbol followed by a two or three letter prefix, a sequential lot num- ber, a one to three letter manufacturer’s symbol, a two number group, and possibly a lot suffix. An example of an ALN is:

GH-221-HAW-72

GH = Cartridge, Caliber .50 221 = 221st lot

HAW = NAD Hawthorne (assembly activity) 72 = Assembled during the year of 1972.

1-3.5.3. Prefix Designation. The two or three

letter prefix designation identifies the size and type of ammunition item. A prefix designation having the final letter R denotes renovated items.

1-3.5.4. Sequential Lot Number. The one to

four character group following the prefix indicates the sequential lot number of that particular type produced by an activity during the calendar year. This group consists of numbers 1 through 9999.

1-3.5.5. Manufacturer’s Letters and Num- bers. From one to three letters identify the ord-

nance activity that assembled the ammunition item. Following the symbols is the final numerical group, indicating the last two digits of the calendar year of assembly.

1-3.5.6. Lot Suffix. An alpha character, follow-

ing the year of assembly, indicates some type of special screening was performed.

1-3.5.7. Grand Lot Designation. A Grand Lot

(GL) designation may be assigned to serviceable remnant ammunition items of the same type after depot inspection. These remnant lots are consoli- dated and reissued with a new ammunition lot number having a GL designation.

1-3.5.8. Uniformity of Functioning. To pro-

vide for the most uniform functioning, all of the components in any one lot are manufactured under as nearly identical conditions as practicable.

1-3.5.9. Ammunition Data Cards. The ammu-

nition data card Figure 1-1, is a basic reference document prepared in accordance with MIL-STD- 1168 for each lot of accepted ammunition. These cards are used to record the lot and serial numbers of each major component, applicable drawings, and other pertinent data such as date of manufac- ture, NSN, and applicable instructions or remarks. Data cards may be supplied with each shipment of ammunition and are placed inside ammunition shipping containers. Data cards may be available from the Naval Surface Warfare Center Crane Division (Code 4021).

1-3.6. Lettering. Stenciled or stamped lettering

on the ammunition includes all the information necessary for complete identification and is marked in compliance with NATO standards and Department of Transportation (DOT) regulations. In addition to standard nomenclature and lot num- bers, lettering may include such information as the Mark and Mod, the fuze type, and the weapon in which the item is fired.

1-4. PAINTING

1-4.1. Purpose. Ammunition is painted to pre-

vent rust and to provide, by the color, a means of identification or camouflage. A color code system is used to indicate the primary use of the ammuni- tion, the presence of a hazardous (explosive, flam- mable, irritant, or toxic) filler, and/or the color of tracers, dye loads, and signals.

1-4.2. Color Coding. Color coding for ammuni-

tion 20mm and larger is contained in MIL-STD- 709, latest revision. Color coding for ammunition smaller than 20mm is contained in this manual.

1-5. PACKING

Ammunition containers are designed to with- stand conditions normally encountered in handling, storage, and transportation to comply with DOT regulations. The ammunition is packed, and the containers are lettered in accordance with pertinent drawings and specifications to include all content information.

1-6. INSPECTION

Ammunition is manufactured to rigorous spec- ifications and thoroughly inspected before accep- tance. Ammunition in storage is periodically inspected and tested in accordance with specific instructions of the Naval Sea Systems Command.

1-7. GRADING

Small arms ammunition is graded per SB 700- 1300-1 which assigns functional condition codes. For example, lots formerly assigned grade R and AC will be converted to functional code A, unless otherwise restricted or suspended.
