The general requirement was for a gun capable of defeating a ship protected by a 15-inch belt and a 7-inch deck. 20年后的94都要3万米才能打穿8寸水平甲,1920年代的炮弹要18寸穿7寸水平,不就是30kyd以上的交战距离。
In the opinion of the DNO, the greater striking-energy of the heavy projectile would have little effect on the ability of the shell to perforate in a fit state to burst. Calculations were also made for the 18-inch gun with 8 crh projectiles of 3,353 pounds and 2,837 pounds and muzzle velocities of 2,500 feet per second and 2,700 feet per second respectively. The remaining velocities were found to be the same at 23,000 yards and only differed by 25 feet per second at 30,000 yards.
These turret designs were given a maximum gun-elevation of 40° or 45°, which, it was thought, was necessary in order to obtain the maximum possible range. 炮弹都为了30kyd的远距离交战优化了存速,炮塔也要求了要能打42kyd,装备这个炮和同等防护的3系列也是考虑了和大和一样的3万米交战。加上比94更大的弹重(1.5吨),同距离落角比94更大。几乎同距离同落角倾斜25度对上这个能和7度防94有一样的等效?
