Sustainment operations focus is primarily on which phase?

• A. Development phase.
• B. Retirement phase.
• C. Focus during the Operations and Support phase.
• D. Concept phase.

Answer: (C)

Sustainment operations are about keeping a system or program operating effectively once it is in use, which means the emphasis sits in the Operations and Support phase. In this phase the system is fielded and requires ongoing maintenance, logistics, updates, training, and health and safety support to maintain readiness and performance. The earlier phases—concept and development—are about creating the capability, not keeping it functioning in the field, while the retirement phase focuses on decommissioning and disposal. So the primary focus of sustainment is the period when the system is active and must be continuously supported.
