ORGANIZATION OF A LARGE FLEET SHIP
The organization of the supply department may differ on larger ships. The more personnel aboard, the more complex the supply department becomes. As you study figure 1-2, you will notice three additional divisions. These divisions are found on larger fleet ships.

S-5 Division
The S-5 division is made up of personnel from the MS rating also. They do work that is similar to work done in the S-2 division, with the exception that their duties are performed in officer's country. These duties may include receiving, stowing, issuing, and accounting for foodservice and other stores. They also prepare and serve all meals in the wardroom and perform other jobs such as cleaning, delivery, and pickup of officers' laundry.

S-6 Division
The S-6 division performs all functions related to procurement, receipt, stowage, issue, and accounting for aviation material. This division is manned and operated by personnel from the Aviation Storekeeper (AK) rating.
S-7 Division
The S-7 division operates all data processing equipment, maintains files and records, and prepares and processes documents to produce records and reports as provided for in the automated supply and accounting system. This division is manned by personnel from the Data Processing (DP) rating.

SECURITY OF SUPPLY DEPARTMENT SPACES
Probably the most important aspect of the supply department is security. The supply officer is responsible for making sure func-tional areas remain on track; however, many problems may be met if security is not main-tained. Security regulations are listed in the Ships Store Afloat, NAVSUP P-487, and the Afloat Supply Procedures, NAVSUP P-485, that you, as an SH3, will need to know. Your knowledge of these regulations will not only help you to keep your area on track, but also help keep the supply department on track. Read, remember, and follow security regulations.

There are a few general rules you will need to remember to keep supply department spaces secure.
l All stock should be kept under lock and key.
. Supply spaces should be locked when unattended by authorized personnel.
. Responsibility for security rests with the person in charge of each space.
. Permission for entry of unauthorized personnel into a supply department space will be obtained from the supply officer or the designated assistant.
. No space will be secured in such a manner to prevent access by use of damage control equipment during an emergency.
. All keys to supply spaces will remain aboard ship in a key locker.
. A key log will be maintained to identify the holder of the key.
. Combinations to combination locks will not be recorded in writing except as prescribed in the NAVSUP P-487.
. All key padlocks should be 1 1/ 2-inch pin-tumbler type, with a dead bolt made of either brass or bronze.
. Keyless padlocks should be the three-combination manipulation type.
