What is Sustainment Maintenance?

• A. Off-system maintenance that primarily repairs and returns equipment and components to the supply system.
• B. On-system maintenance that repairs and returns equipment to the operator.
• C. Maintenance performed by civilian contractors only.
• D. Inventory management of spare parts.

Answer: (A)

Sustainment maintenance is the maintenance work done off the user platform to repair and restore equipment so it can be returned to the supply system. This usually happens at depots or repair facilities, not by the operator on the battlefield or in field conditions, and it aims to keep the overall battle or mission capability by reconditioning components for reuse. That’s why the description of off-system maintenance that repairs and returns equipment and components to the supply system fits best. On-system maintenance would involve repairs performed on the equipment by the operator, returning it directly to use rather than sending it back into the supply chain. Maintenance performed only by civilian contractors is too restrictive, since sustainment maintenance can be conducted by military and civilian entities depending on the context. Inventory management of spare parts is a logistics task, not a maintenance function.
