Ships in Reduced Operating Status

Ships in reduced operating status have small cadre crews aboard to assure the readiness of propulsion and other primary systems if the need arises to activate the ship. The cadre crews vary in size based on the type of ship and the length of reduced operating status. ROS-4 indicates it will take four days to make the ship ready to sail, fully crewed and operational. ROS-90 indicates ninety days to full operations status from time of notification to activate.
