Where is the first plane established for combat system alignment?

The Master Reference Plane is the first plane established for combat system alignment because it serves as the fundamental baseline for all other measurements and alignments in a combat systems environment. This reference plane is critical because it allows for accurate positioning and alignment of weapons systems, sensors, and other combat-related technologies. Establishing this plane ensures that subsequent calculations and adjustments are based on a consistent and reliable standard, thus enabling effective tracking and targeting capabilities essential for operational readiness.

In the context of combat systems, other reference planes may be used for specific functions or subsystems, but the Master Reference Plane is the overarching standard against which all other measurements and alignments are made. Establishing this plane first ensures that any modifications to the system or adjustments due to different operational scenarios are accurate and consistent throughout the combat system's operations.
