This gun started life in 1898 as the 13"/35
(33 cm) Mark 2 Mod 1 Serial Number 23. It was later converted to
the 16"/28.8 (40.6 cm) Mark A Mod 0 Experimental Gun, the USN's first gun
of that caliber. Gun was bored out and hooped to the muzzle.
It is shown here rusting away in March 2005 at the "Bone yard" at the Naval
Surface Warfare Center in Dahlgren, Virginia. Maximum range in this
16" (40.6 cm) configuration with a 2,100 lbs. (953 kg) projectile and a
muzzle velocity of 1,800 fps (549 mps) was 25,100 yards (22,950 m).
Rifling was 96 grooves uniform RH 1 in 20.
