The Air Force Stock Fund consists of six divisions: Systems Support, General Support, Medical-Dental, Fuels, Commissary, and Air Force Academy Cadet Store. These divisions provide for the financial management, inventory control, and distribution of consumable items of supply and low-cost equipment to support both peacetime and wartime operations. The stock fund operates under a revolving fund concept. The corpus of the stock fund consists of inventory and cash. Each division buys and holds inventory for sale to authorized customers (primarily operation and maintenance funded activities and the Air Force Industrial Fund) on demand. Sales of stock fund inventory generate cash that is used to replenish inventory levels. In a static environment, this sale and replenishment cycle is self-sustaining. However, introduction of new weapon systems, modification of existing systems, and increased levels of peacetime operation require expansion or augmentation of stock fund inventories to assure proper levels of support and readiness.
