What is the focus of the Sustainment phase in the ship's life cycle?

The Sustainment phase in a ship's life cycle primarily concentrates on maintaining operational proficiency. This phase is crucial as it ensures that the ship and its crew remain effective and prepared for ongoing operations after any initial deployments or engagements. During this period, the focus is on regular maintenance, necessary repairs, and ongoing training to keep skill levels high and systems functioning optimally.

While advanced tactical drills, training for new missions, and preparing for deployment are important aspects of a ship's overall readiness, these activities are often emphasized in other phases of the life cycle, such as the pre-deployment phase or training phases. The Sustainment phase is specifically about sustaining the effectiveness and readiness of the ship and crew over time, ensuring they can respond to operational demands as they arise.
