Depot maintenance expenses are funded by which appropriation?

• A. Procurement
• B. MILCON
• C. O&M
• D. RDT&E

Answer: (C)

Depot maintenance is a sustainment activity—the ongoing work to keep equipment ready and repair it when needed. That kind of day-to-day operating cost is funded from Operations and Maintenance (O&M), which covers labor, parts, contracted maintenance, and depot facilities tied to maintaining weapon systems. Procurement funds are for buying new equipment, MILCON funds for military construction, and RDT&E funds for research and development and testing. So depot maintenance expenses are funded by O&M because they represent routine, ongoing maintenance rather than new purchases, construction, or development.
