What is the primary responsibility of the Navigator (NAV)?

• A. Navigation and mission planning.
• B. Weapons and combat systems.
• C. Supply and logistics.
• D. Safe navigation and mission execution.

Answer: (A)

The main thing the Navigator handles is charting the ship’s path and preparing how to get there safely. That means plotting courses, fixing the ship’s position, calculating speed, distance, and ETA, and planning the voyage with fuel and time considerations in mind. It also includes laying out the mission plan—the route, waypoints, anticipated hazards, weather and sea conditions, and contingency options—so the crew can execute the voyage smoothly. The focus is on how to move from point to point safely and efficiently, not on carrying out every action of the mission itself. Weapons and combat systems belong to a different department, and supply and logistics to another, while “safe navigation and mission execution” blends execution responsibilities with navigation; the primary emphasis for the Navigator is the navigation and the planning that makes the mission possible.
