Shannon carried unique ten-inch muzzle-loading guns whose ammunition chain did not extend to her intended overseas station. Only the rounds aboard ship were available, while even nine-inch ammunition was scarce enough to restrict practice. Her largest weapons consequently went unexercised, making their impressive paper strength of little practical value. The episode shows how overseas logistics, training stocks, and fleet standardization have to be designed alongside a warship's armament.
