The U.S. Navy would not be able to do what it does without its fleet of non-commissioned auxiliary vessels, especially its fleet oilers and resupply ships. USNS Kanawha refuels the cruiser USS San Jacinto and the destroyer USS Roosevelt while underway in this photo, with the USS Nitze and USS Mason awaiting their turn at the pump.
The USNS Kanawha not only provides fuel for these guided missile destroyers and cruisers’ own propulsion but also for their aviation detachments. In total, the Henry J. Kaiser Class, which the Kanawha is one of, can hold a whopping 7,800,000 gallons of fuel oil or jet fuel. It can also move spare parts, food stuffs, munitions and even personnel to its “customers” while executing an underway replenishment.
