Sustainment operations focus is most closely aligned with which phase?

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

Answer: (C)

Sustainment operations are about keeping a system running and effective once it’s in use. This includes ongoing maintenance, logistics, spares, field support, training, and upgrades to maintain readiness and performance throughout the system’s life. That focus fits the Operations and Support phase, which covers delivering and sustaining a system in the field. The Concept phase is about defining needs and proving viability early on, the Development phase is about building and integrating the system, and the Retirement phase is about decommissioning and disposal at the end of its life. So sustainment aligns with Operations and Support.
