What is the material readiness condition designation for ships before going to sea or when entering port during war?

The material readiness condition designation for ships before going to sea or when entering port during war is known as "Zebra." This designation indicates that the ship is in a heightened state of security and readiness, particularly for active combat situations. It involves securing the interior of the ship by closing watertight and fire doors, ensuring that personnel are ready for immediate response to threats, and maintaining essential equipment in working order. The Zebra condition is vital for ensuring that the vessel can effectively respond to emergencies such as flooding or fire while navigating hostile environments.

The other options represent different conditions of readiness that do not carry the same implications for pre-deployment and wartime security measures as Zebra does. For example, Alpha usually indicates a lower state of readiness, focusing more on routine operations rather than preparing for immediate conflict.
