504-892: The fleet, while the earlier Colliers supplied coal-burning steamships . Specific role replenishment vessels include combat stores ships , depot ships , general stores issue ships , and ammunition ships . Tenders are specifically designed to support a type of smaller naval unit, like submarines , destroyers , and seaplanes , providing a mobile base of operations for these units: specifically destroyer tenders , submarine tenders , seaplane tenders , torpedo boat tenders . Supporting front-line operating bases requires immense transportation capacity. Transport ships are often converted merchant ships simply commissioned (APA, APD, APH, APV) into naval service. Tankers are transports specifically designed to ship fuel to forward locations. Transport ships are often employed not only carrying cargo for naval support but are in support of all forces of
532-442: The most direct ways that auxiliary ships support the fleet is by providing underway replenishment (also known as "replenishment at sea") to major fleet units. This allows the fleet to remain in the same location, with the replenishment vessels bringing up fuel, ammunition , food, and supplies from shore to the fleet wherever it is operating. Oilers ("replenishment tankers") are vessels specifically designed to bring fuel oil to
560-520: The open sea, also disabled ships. Repairing ships at sea or in conflict areas is important as it allows these vessels to return to service more quickly, while also increasing the chance of survival for ships critically damaged in battle. Repair vessels (US Navy: AR, ARB, ARC, ARG, ARH, ARL, ARV) range from small equipment ships known as Auxiliary repair docks , to the larger Auxiliary floating drydocks , there are also Aircraft repair ships that specialize in repair of naval aircraft . Harbor support
588-560: The primary fleet vessels would be unsupported. Thus, virtually every navy maintains an extensive fleet of auxiliary ships, however, the composition and size of these auxiliary fleets vary depending on the nature of each navy and its primary mission. Smaller coastal navies tend to have smaller auxiliary vessels focusing primarily on littoral and training support roles, while larger blue-water navies tend to have larger auxiliary fleets comprising longer-range fleet support vessels designed to provide support far beyond territorial waters .
