The 13"/35 caliber gun Mark 1 (spoken "thirteen-inch-thirty-five-caliber") was used for the primary batteries on eight of the first nine
The Navy's Policy Board called for a variety of large caliber weapons in 1890, with ranges all the way up to 16-inch (406 mm). A 16-inch caliber gun was beyond US manufacturing capabilities at this time though and the largest gun possible was the 13-inch (330 mm)/35 caliber. The Navy intended to use this gun in short-range action against heavily armored targets and was fitted to the first true battleship in the US Navy, Indiana. This turned out to be the only 13-inch gun developed for the US Navy.[2]

Incidents
Gun No. 2, mounted on Indiana, suffered from erosion at the front slope of the chamber and was replaced with another gun. It was first reported in September 1897, after only 32 rounds had been fired. In May 1902, No. 2 was sent back to the US Naval Gun Factory to be relined. After having had 71 rounds fired through it, and finding that guns built at the same time and fired the same number of rounds showed no sign of erosion, it was determined that the erosion was due to a defect in the manufacture of the forging.[4][5]
Gun No. 13, mounted on Kearsarge, was injured in January 1901, when a shell exploded prematurely in the barrel. It was repaired with a lining tube inserted into the barrel and used at the Naval Proving Grounds.[6]
Gun No. 18, mounted on Kentucky, suffered an injury while on Asiatic station, probably from a shell exploding in the bore. It was replaced with another gun.[7]
Gun No. 34 was completely disabled by an accident to its tube; it was reassembled with new forgings.[8]
