What international flag configuration does the Navy employ to warn of divers in the water?

The correct answer is the Alpha Flag, which is specifically used to signal that there are divers in the water. This flag is part of the International Code of Signals and is recognized globally. The Alpha Flag is a blue and white striped flag that indicates the presence of divers and warns other vessels to maintain a safe distance to ensure the divers' safety. This is a critical safety measure in diving operations, as it alerts surface traffic to the potential hazards posed to divers at the surface.

The other flags mentioned, while they have their own specific uses in maritime communication, do not pertain specifically to warning of divers. The Bravo Flag indicates that there is a handling of dangerous cargo or material, the Code Flag is a general reference for various messages, and the Delta Flag is used for indicating a maneuvering condition, which is unrelated to dive operations. Understanding the specific meanings of these flags is essential for ensuring safety in waters where divers are present.
