At some point the ship received eight, and then later ten more, Hotchkiss 5-barrel revolving guns. They fired a shell weighing about at a muzzle velocity of about to a range of about . They had a rate of fire of about 30 rounds per minute. The hull was not recessed to enable any of the guns on the battery deck to fire forward or aft. However, the guns mounted in the barbettes sponsoned out over the sides of the hull did have some ability to fire fore and aft. Late in the ship's career four above-water torpedo tubes were added.
