Which list correctly identifies the three maintenance levels?

• A. Depot, Operational, Intermediate
• B. Depot, Local, System
• C. D-Level, T-Level, M-Level
• D. Primary, Secondary, Tertiary

Answer: (A)

Maintenance on ships is organized into three levels reflecting the scope of work and who performs it. Depot maintenance is the highest level, done at specialized depots with the capability for major overhauls and rebuilds of entire systems. Intermediate maintenance sits in the middle, handled at regional repair facilities for more complex repairs that go beyond on-board capabilities but don’t require a full depot overhaul. Organizational (often called operational in some texts) maintenance is performed by the ship’s own crew for routine preventive maintenance, troubleshooting, and minor repairs to keep equipment ready.

The correct list includes depot, operational, and intermediate, which matches the standard three-tier maintenance framework used in Navy practice. The other options use terms that don’t correspond to these recognized levels.
