The 12"/35 caliber gun (spoken "twelve-inch-thirty-five–caliber") were used for the primary batteries of the United States Navy's "New Navy" monitors Шаблон:USS and Шаблон:USS and the battleships Шаблон:USS and Шаблон:USS.Шаблон:Sfn

Mark 1

The Navy's Policy Board call for a variety of large caliber weapons in 1890, with ranges all the way up to Шаблон:Convert, led to the development of the Шаблон:Convert/35 caliber gun. The Mark 1, gun Nos. 1–8, was constructed of gun steel, having a tube, jacket, ten hoops and a locking ring. The Mod 0, the original design, had the inner hoop starting Шаблон:Cvt from the breech and running out to the muzzle, with the Mod 1 being hooped from breech to muzzle.Шаблон:SfnШаблон:Sfn

Mark 2

The Mark 2, gun Nos. 9–14 and 57, was of similar construction to the Mark 1 but with seven hoops starting from the breech and running out to the muzzle. The Mark 2 Mod 1 and Mod 2 were also given a new nickel-steel liner.Шаблон:SfnШаблон:Sfn

Incident

Gun No. 9, mounted in IowaШаблон:'s forward turret in the left-hand position, was damaged on 9 April 1903, off Pensacola, Florida, when the chase, forward of the "D" hoop, was blown off during target practice. The gun had been assembled in 1895 at the US Naval Gun Factory. The gun had fired 127 rounds with the accident happening on the 128th round. No one inside the turret were injured, but fragments of the chase were driven through the deck under the muzzle killing three men on the deck below; four others were slightly wounded. The gun was removed and sent back to the Naval Gun Factory to be examined by a special board. Their theory was that a pressure wave had built up from the burning of older smokeless powder used.Шаблон:Sfn
