In artillery corrections, what does 'Splash' signify?

'Splash' is a term used in artillery communications to indicate the moment of detonation of a projectile upon reaching its target. This designation is crucial because it informs the observer or the forward observer (FO) exactly when the projectile has impacted or detonated, allowing for timely and accurate assessment of the fire's effect. By acknowledging the 'splash,' personnel can gauge whether the round has hit within the desired parameters and can subsequently make timely corrections for subsequent fire missions if required.

Understanding the precise timing of the splash also aids in coordinating follow-up actions, such as whether to adjust the fire mission or prepare for the next phase of the operation. It essentially serves as a pivotal marker in the sequence of artillery fire support.
