What are the effects of base drag on a projectile?

Base drag refers to the aerodynamic resistance encountered by a projectile at its rear, which plays a significant role in its flight dynamics. When a projectile moves through the atmosphere, it displaces air, creating a wake behind it. Base drag occurs due to the formation of this wake and the resulting pressure differential, which can slow the projectile down.

As a consequence of this drag, the projectile experiences a reduction in velocity, which directly impacts its range and precision. Slower projectiles may not travel as far as intended, as they lack the kinetic energy required to maintain longer distances. Additionally, a decrease in speed can lead to a destabilization of the projectile's flight path, ultimately affecting its accuracy. Thus, the presence of base drag is detrimental to the performance of the projectile, influencing both how far it will travel and how precisely it will hit its target.
