How many transmissions are sent to the ship for the NSFS call for fire?

In the context of naval gunfire support (NGFS) and the naval surface fire support (NSFS) call for fire, the correct number of transmissions sent to the ship is two. This process typically involves two key communications: the initial call for fire and the result of that call, which either confirms the target location, provides adjustments if necessary, or communicates the outcome of the fire mission.

The first transmission includes essential information such as the target location, the nature of the fire mission (i.e., a request for fire), and any specific adjustments if the observer has prior information on the target. The second transmission is the response from the naval gunfire ship, which may include corrections or confirmations based on the engagement, enabling the observer to ensure that the fire is effective.

This two-step process allows for clarity and ensures that both the observer and the naval unit have a mutual understanding of the target and the desired effect, ensuring better coordination and success in supporting ground operations.
