回复 necrons 的帖子
没人给SKC34翻案,只是觉得法国15吋舰炮的数据有太多不合理的地方!
发射药能量不同,3年式膛压3,070 kg/cm2,而美国的MK5只有2835kg/cm2。甚至连老衲的著名垃圾MKI,换1021KG,229KG发射药,都能打出785m/s的初速来。
According to "Naval Weapons of World War Two," a 2,250 lbs. (1,021 kg) APC shell was proposed to correct some of the problems encountered by the too-light shell, but "financial stringencies in the early 1930s prevented any change." It was estimated that a 506 lbs. (229.5 kg) charge of SC381 would give this heavier projectile a new-gun muzzle velocity of 2,575 fps (785 mps) and a range of 40,500 yards (37,030 m) at an elevation of 40 degrees
