John Randolph Spears,
The history of our Navy from its origin to the present day…
(1897)
“ As many of the readers are aware, the Iowa is by no means the best battle-ship in the American navy. For instance, in her main battery she carries four twelve-inch and eight eight-inch breech-loading rifles, and six four-inch536 rifles, known as rapid-fire guns, because they use cartridges on the plan of a revolver or rifle cartridge, and can therefore be fired in service five or six times a minute. The new Kearsarge will carry four thirteen-inch and four eight-inch breech-loading rifles and fourteen five-inch rapid-fire guns. ”
