To ensure a rocket remains stable throughout its flight, the Center of Pressure should be:

The stability of a rocket during flight is significantly influenced by the relationship between the Center of Pressure (CP) and the Center of Gravity (CG). For a rocket to be stable, the CP must be located behind the CG. This arrangement ensures that any disturbances or changes in the rocket's orientation during flight result in corrective aerodynamic forces that help return the rocket to its original flight path.

When the CP is behind the CG, the aerodynamic forces act to create a restoring moment. If the rocket begins to tilt or yaw, the airflow over the rocket generates a force at the CP that pushes the tail of the rocket back towards the direction of flight, stabilizing the rocket’s trajectory. Conversely, if the CP is in front of the CG, those same disturbances can lead to an increasing tilt, exacerbating the instability and potentially leading to a loss of control.

This principle forms the foundation of rocket stability and is crucial for successful flight. Therefore, having the CP behind the CG is essential for maintaining a stable flight path throughout the rocket's ascent and descent.
