An appropriation type used for the ongoing costs of operating and maintaining systems is known as what?

• A. RDT&E
• B. Unresolved supportability issues
• C. Operations and Maintenance (O&M)
• D. Designing for producibility

Answer: (C)

Ongoing operating and maintenance costs are funded through the Operations and Maintenance appropriation. This type covers day-to-day expenses needed to keep systems functioning, such as salaries, fuel, utilities, routine maintenance and repairs, spare parts, and training. It distinguishes from funds used for developing or acquiring systems, which fall under RDT&E, and from other concepts like producibility design or unresolved supportability issues, which are not appropriations for ongoing operations.
