The General Services Administration controls items
of material that are common to both military and civilian
worlds. Examples of GSA items are paint, paper,
handtools, chalkboards, movie projectors, and the like.
GSA items are stocked at the naval supply centers
located in Norfolk Virginia; and San Diego, California.
DEFENSE LOGISTICS AGENCY (DLA)
The Defense Logistics Agency controls items of
material that are common to all the military services but
not to the civilian world. Examples of DLA items are
fuels and bullets. DLA items are also stocked at the
Norfolk and San Diego naval supply centers.
INTEGRATED NAVY SUPPLY SYSTEM
The Navy supply system is an integrated system,
allowing materials to be obtained usually from more
than one point in the system. In the remainder of this
chapter, we will discuss the Navy supply system in
general, introduce the primary instructions and forms,
and provide a brief description of how to use the system
to get parts and supplies.
The following is a description of how the integrated
Navy Supply System might react to a typical supply
USS Ship requisitions cognizance symbol 9N
material from the NSC.
The NSC, a Navy retail stock point, usually
ships the requested material. However, after
screening its stocks, the NSC determines that the
requested material is not carried. It then refers
the requisition to the Defense Electronics
Supply Center (DESC), Dayton, the cognizant
The DESC, Dayton, after researching its master
records and determining that the material is
available at NSC Oakland (a specialized support
point), refers the requisition to NSC, Oakland.
The NSC, Oakland, issues the material to USS
The NSC, Oakland, then makes an issue
transaction report to DESC, Dayton.
The DESC, Dayton, after applying the issue
report to its master record, learns that stock of
the item at NSC, Oakland, is below the required
level and issues a contract to the ABC
Corporation for additional stocks of the item.
The ABC Corporation ships the material to
The NSC, Oakland, makes a receipt transaction
report to DESC, Dayton.
As you can see, if an item is not available at the local
NSC, the requisition does some traveling. So it may take
a little time to get the item you requested.
The COSAL/COSBAL is the document that drives
the operational and supply support for a ship. It is a
dynamic document that changes constantly, as the ships
configuration changes. Each ship in the U.S. Navy has
its own COSAL or COSBAL tailored specifically to its
mission. The COSAL or COSBAL lists include the
The equipment or components required for the
unit to perform its operational assignments
The repair parts and special tool required for the
operation, overhaul, and repair of those
The miscellaneous portable items necessary for
the care and upkeep of the unit
The COSAL/COSBAL is both a technical
document and a supply document. It provides
nomenclature, operating characteristics, specifications,
parts list, and other technical data pertaining to all
installed equipment and machinery. It also provides
nomenclature and characteristics of the equipage and
tools required to operate and maintain the unit and its
No one can predict exactly when a circuit card in an
AN/URT-23 will fail or when a bearing will wear out in
a freshwater pump. However, the COSAL/COSBAL
can help maintenance and supply personnel in a unit to
make an educated guess. The COSAL/COSBAL
computers analyze the frequency of failures of parts
used aboard units and, based on these analyses, develop
an allowance of repair parts that the supply officer
The COSAL/COSBAL is used primarily for two
purposes-to identify repair parts (storeroom items) and
to determine operating space allowances (equipage).
