United States Navy Fleet Oilers are specialized ships designed to provide fuel and supplies to naval vessels at sea. They play a crucial role in extending the operational range of the fleet by enabling ships to refuel without returning to port. This capability is essential for maintaining a continuous naval presence and supporting various missions. Fleet Oilers are equipped with advanced pumping systems and storage tanks to transfer fuel efficiently. They can operate in various sea conditions and are often accompanied by escort ships for protection. These vessels ensure that the United States Navy can sustain its operations during extended deployments.
