Fleet replenishment refers to the process of supplying ships or aircraft with necessary resources, such as fuel, food, and ammunition, to ensure they can continue their operations effectively. This is crucial for maintaining the operational readiness of military forces, as well as for commercial shipping fleets that require regular supplies to function efficiently. In military contexts, fleet replenishment often involves specialized vessels known as replenishment ships that are designed to transfer supplies at sea. This capability allows naval forces to remain deployed for extended periods without returning to port, enhancing their strategic flexibility and operational reach.
