What is the primary function of the S-3 afloat supply division?

The primary function of the S-3 afloat supply division is to manage ship services, which encompass a variety of critical supply and logistical support roles necessary for the smooth operation of a naval vessel at sea. This division is responsible for the distribution of necessary materials, supplies, and equipment that ensure the crew can perform their duties effectively. Responsibilities include managing the ship's inventory of parts, tools, and general supplies, as well as handling the procurement and distribution processes needed to maintain operational readiness.

S-3's focus on ship services is integral because it plays a key role in maintaining equipment, ensuring safety, and managing consumable goods that support daily operations on board. This function is vital for a ship’s ability to sustain itself over long periods without access to port, directly contributing to its mission readiness and overall effectiveness in various operational environments.
