FINAL COMMENTS:
最后观点：
At about 40,000 yards, the U.S. Navy 16"/50 firing a 16" Mark 8 Mod 6 AP projectile (the later Mod 7 and Mod 8 designs were post-WWII, so I usually do not count them and they were no better ballistically, to my knowledge) will hit at about 45° downward angle and 1607 feet/second (489.8 m/sec). Just as with a point blank hit at 2500 feet/second (762 m/sec) and 45° obliquity, this hit too will barely hole the plate as the projectile is hitting at 0° (normal) obliquity, though not completely penetrate it. Any slight barrel wear will lower the muzzle and striking velocities and no holing will occur at THESE OR ANY OTHER ranges, as mentioned. However, this is so far above any real fighting range (even with radar it is hard to see the target due to the earth's curvature interfering, especially in any kind of imperfect seeing conditions) that I do not even consider it in my computations, while putting the gun barrel up to almost touching the enemy turret is also a pipe dream in real life! Thus, no holing or complete penetrations, ever, though possibly some cracking of the plate and possible jamming of the turret if the crack-off plate piece is dislodged badly enough. 大约在40000码距离上，美国海军16"/50 炮所发射的 16" Mark 8 Mod 6 AP弹头（ Mod 7 和 Mod 8是战后才出现的，因此虽然他们的弹道性能更好但我通常不予考虑）会在45°的落下角，以1607 feet/second (489.8 m/sec)的速度下落。就算它以2500 feet/second (762 m/sec) 和 45°倾斜角命中标靶，一样不能在这装甲上开洞。即使是垂直击中仍不能完全穿透它。轻微的炮膛磨损都将减低初速和命中时的速度而无法在这样的距离上留下坑洞。当然，实际战斗不可能发生在这样的距离(由于地球的曲率影响，就算有雷达也很难看到目标，尤其是在恶劣天气下)因此我根本不会去考虑。但把炮口几乎伸到别人的炮塔面前才开炮在现实生活里无疑是个白日梦！因此开洞或完全穿透是不可能，当然假如崩裂的装甲碎块落到足够坏的位置上，倒可能会将炮塔卡住。
Therefore, these plates are the only warship armor plates that could not be completely penetrated by ANY gun ever put on a warship when installed leaning back at 45°, as they were in the actual turrets!!! Even to completely hole the plate all the way through at that inclination requires a brand new 16"/50 Mark 7 or German 38cm SK C/34 gun at point-blank range firing the latest versions of their respective AP projectiles; it might be cracked at a lower striking velocity, but no hole put entirely through it! AND THEY SAID GUNS HAD COMPLETELY OVERMATCHED ALL ARMOR--*NOT SO*!!!
由于这种装甲实际安装在炮塔时带有45°向后倾斜的安装角，因此任何曾经搭载在战舰上的火炮都不能将其完全击穿！！！就算要在这样倾斜的装甲上开个完整的弹孔，需要一门全新的16"/50 Mark 7 或德国的 38cm SK C/34在打靶那样的距离发射各自最新的AP弹头；在较低撞击角度时有可能击碎，但绝不可能打出弹孔击穿它。他们说火炮已经完全打败所有装甲——才不是！！！
