The ship's construction was delayed by multiple changes ordered while she was being built—reflecting battle experience with earlier monitors. This included the rebuilding of the turrets and pilot houses to increase their armor thickness from to 10 inches and to replace the bolts that secured their armor plates together with rivets to prevent them from being knocked loose by the shock of impact from shells striking the turret. Other changes included deepening the hull by to increase the ship's buoyancy, moving the position of the turret to balance the ship's trim and replacing all of the ship's deck armor. Completion of the ship was further delayed by the low depth of the Ohio River which prevented her movement from Cincinnati in December 1864 to finish
