The first class of short-range ships as envisioned by the policy board were to mount 13-inch/35 caliber and new guns, with of belt armor, of deck armor and of armor over the casemates. The "Indiana" class, as actually built, exceeded the design in displacement by 25 percent, but most other aspects were relatively similar to the original plan. An belt and a secondary battery of and guns were adopted, the latter because the Bureau of Ordnance did not have the capability to construct rapid-firing 5-inch weaponry. The larger weapons were much slower firing and much heavier, but without the bigger guns, the ships would not be able to penetrate the armor of foreign battleships.
