Type 95 sight was originally designed with a maximum target speed of 600 kilometers per hour; however, experience showed that aircraft often exceeded this speed. To compensate for the problem, a ring was added to the sighting telescope to provide an additional offset for speeds up to 900 kilometers per hour. The gun was normally used without a gun shield, although some multiple mounts on Yamato-class battleships were fitted with Ducol high tensile steel shields. Many ship-based mounts also had splinter shields. Ammunition The Type 96 cartridge case was a rimless type design with a deep extraction groove at the base. The projectiles fired by the weapon were slightly unusual in that they had two rotating bands. The forward band was slightly smaller in diameter than the rear band. It was believed that this was to reduce wear on the rifling near the chamber. The case of the cartridge was crimped around the rear rotating band. The complete round weighed approximately with the projectile weighing . The propellant was 102 grams of single-perforated, graphited grains of nitrocellulose approximately 2 millimeters in diameter and between 2.5 and 4.5 millimeters in length. Normally one tracer round was added every four or five rounds to aid laying. High-explosive shell. Orange body. High explosive incendiary. Green body. High explosive tracer. Orange or red body. High explosive tracer self-destroying. Orange or red body. Armor-piercing. Black, white or smoky blue body. Approx 42 mm penetration at 0-100 m and 0 degrees from normal. Variants Type 94 - French built Type 95 - French built Type 96 - Built in Japan Type 96 Model 1 - Used on land and in warships in single, double and triple mountings (also known as double 25 and triple 25). The single mount was free swinging, while double and triple mounts had hand-wheel traverse. Type 96 Model 2 - Used on warships in double and triple mountings. Type 96 Model 3 - Used on warships in single free-swinging mounts. Type 96 Model 4 - Used on submarines, in single, double and triple mounts. Single mounts can be manually lowered into the submarine. Type 96 Model 4 mod 1 - Used on submarines in free-swinging single mounts. Could not be lowered into the submarine. Type 96 Model 4 mod 2 - Used on submarines in free-swinging single mounts. Could be remotely lowered into the submarine. Type 96 Model 5 - Used on
