Which option is not a typical input to a fire control solution for a naval gun engagement?

• A. Target range
• B. Target speed
• C. Wind
• D. Color of the target

Answer: (D)

The firing solution for a naval gun relies on physical factors that influence where the shell will go and when it will arrive. Knowing the range to the target provides the distance the shell must travel, which sets the elevation and estimates the time of flight. The target’s speed lets the system predict where the target will be when the shell arrives, so you can place your shot by calculating the lead. Wind is factored in because it can push the shell off course during its flight, so wind corrections are applied to maintain accuracy. These inputs—range, target speed, and wind—are all directly tied to the ballistic path and timing of the shot.

The color of the target doesn’t affect any of those ballistic parameters. It’s an identification cue, not a factor that changes trajectory, time of flight, or lead calculations. That’s why it’s not a typical input to the fire control solution.
