Which ships are designated for providing underway replenishment to fleet units?

Combat Logistics Ships are specifically designed to provide underway replenishment to fleet units. This type of ship is equipped with the necessary systems to transfer fuel, ammunition, and other supplies to warships while they are at sea, enabling them to remain operational without the need to return to port frequently.

These ships play a crucial role in sustaining long-term naval operations, as they allow the fleet to extend its operational reach and maintain a continuous presence without interruption for resupply. Other types of ships, such as Mine Warfare Ships, Amphibious Warfare Ships, and Surface Combatants, have different primary missions and capabilities that do not focus primarily on the replenishment role. Therefore, they would not be designated for the specific function of providing underway replenishment, which highlights the specialized nature of Combat Logistics Ships in fleet support operations.
