United States Navy Supply Ships are specialized vessels designed to provide logistical support to naval forces at sea. They deliver essential supplies such as fuel, food, ammunition, and spare parts to combat ships and submarines, ensuring that naval operations can continue without interruption. These ships play a crucial role in maintaining the readiness and sustainability of the fleet. Typically, supply ships are equipped with advanced systems for transferring cargo while at sea, allowing them to operate in various conditions. They are often part of a larger group known as the Military Sealift Command, which manages the logistics and transportation needs of the U.S. Navy.
