When is the x-ray condition set on a ship?

The x-ray condition is set on a ship when it is docked in a well-protected harbor. This condition represents a state of readiness where the ship prepares for potential threats while still maintaining a level of security due to the environment. The x-ray condition generally allows for more relaxed security measures as the risk of attack is considered lower during this phase.

In contrast, when a ship is in a state of heightened alert, such as in immediate danger of attack or during wartime at sea, other conditions (such as the zebra or yoke conditions) would typically be established to ensure maximum readiness and security. These conditions close off certain openings to the ship, minimizing access for potential threats. Being underway at full speed would also warrant a different state of readiness, primarily focused on navigating and avoiding threats rather than the specific security posture of the ship while docked.
