officer normally tries to equalize the endurance
of the various types of stores.
The storerooms are not necessarily loaded to
maximum capacity, since endurance limitations
are set by various commands. These limitations
are expressed as the actual number of days of
endurance and are applied to individual items
rather than to types of stores. For example, if the
supply officer wants to stock the storerooms at
a 90-day endurance level, one requisition for a
90-day supply of general stores cannot be sub-
mitted. Each item must be reviewed to determine
a sufficient quantity to last the ship for 90 days.
Another factor supply personnel must consider
is the total weight limitation of stores that may
be brought aboard. Each ship is allowed a specific
weight limitation so that it can maintain proper
stability and buoyancy.
When the desired number of days of endurance
has been reached for a type of store, then
that endurance is converted into quantities of
AVAILABLE SPACE. The amount of
storage space available for an item is an obvious
limiting factor. You cannot stow 100 cubic feet
of material in a 50-cubic-foot space. For this
reason, some extremely bulky items may have to
be carried in a quantity less than the desired level
and reordered frequently. On the other hand,
items of low cost and low bulk may be carried
at a high level to reduce the time spent in
ordering and stowing.
PERISHABILITY. Highly perishable items
may also be stocked at a lower level than other-
wise desired so that deterioration is kept to a
SHIPS EXPERIENCE. The most accurate
guide in the determination of requirements is past
stock records. You adjust the figures obtained
from past usage to cover a specified period in the
future. For example, a 3-month endurance rate
is computed as follows:
Fast-moving itemsmultiply the past months
usage by 3.
Slow-moving itemsdivide the past 6 months
usage by 2.
ALLOWANCE LISTS, INITIAL OUTFIT-
TING LISTS, AND USAGE DATA TABLES.
Allowance lists, initial outfitting lists, and usage
data tables are prepared to help supply officers
of new or recommissioned ships determine
quantities of supplies to stock. Since these ships
have no prior usage to rely on, these lists and
tables help you and the supply department
determine requirements for consumable supplies,
subsistence, and ships store stock. These lists
provide restrictive controls on the types and
quantities of equipage allowed and serve as guides
for types and quantities of supplies required.
Allowance lists as used here do not include the
COSAL Stock Number Sequence ListStoreroom
Item (SNSLSRI) for repair parts.
SHIPS OPERATIONS. Operating factors
may require the review of stock records and the
reevaluation of the requirements for some or all
items stocked. These factors are the expected
length of a cruise, type of operation (combat or
training), expected climate during the operation,
and available supply support.
If the length of a cruise is less than the normal
endurance load, no major adjustment is necessary.
However, if the operation is expected to last
longer, the ships stock of fast-moving and
essential items is reviewed to determine if an
increase is needed.
A ship rescheduled from a hot or temperate
climate to an arctic climate should review
materials needed for cold-weather operations.
An important factor to consider when the ship
is preparing for deployment is the availability of
supply support during the cruise. Will your ship
be operating independently? Will it be in the
company of similar ships? Can your ship obtain
materials from mobile logistic support ships or
ashore activities? All of these questions must be
answered before you can determine the division
or department requirements. You will usually find
this information in the operations orders.
ADVICE OF DEPARTMENTS. Your depart-
ment may require special material or an item in
a greater quantity than is usually stocked in the
storeroom. For example, electrical fittings are
replaced periodically for general station or ships
maintenance. Average usage of these fittings may
be 16 per month. By using the formula described,
