太空船使用cm作为火炮分级,在制作分歧科技太空船和历史帆船的时候,可能会很有违和感
历史帆船的口径参考以下资料
In the 18th century, Albert Borgard, in charge of the Royal Ordnance made the British standardized the weight of cannon balls to be the following:
Mass of Iron Sphere
(lb) Diameter(in)
4 2.99
6 3.43
9 3.93
12 4.32
18 4.95
24 5.44
32 5.99
42 6.56
These were considered standardized because the diameter of each would be close to next half inch, i.e. 4 lb was 3 inches in diameter, 6 lb was 3.5 inches in diameter, 9 lb was 4 inches in diameter and so on.
以上述资料换算
磅 厘米
4 7.5946
6 8.7122
9 9.9822
12 10.9728
18 12.573
24 13.8176
32 15.2146
42 16.6624
行吧,一堆中间值,一个建议(括号内为d伤害):
7cm(11d):4磅炮
8cm(6d×2):6磅炮
10cm(3d×5):9磅和12磅炮
12cm(6d×3):18磅炮
14cm(3d×7):24磅炮
16cm(6d×4):32磅炮与42磅炮
等一下,这伤害对吗?
LT正好有舰炮,看一下伤害:
4磅炮:6d×3(1.8d,1d+3)
9磅炮:6d×4(2.4d,2d+2)
18磅炮:7d×4(2.8d,2d+3)
42磅炮:6d×5(3d)
看起来差不多,甚至好像高一点?但太空船使用的数据是d-伤害,也就是通常的伤害除以10(来简化计算),除以10的伤害见括号

这也差太多了,最大型的42磅炮和太空船武器里最小的2cm火炮差不多伤害
……
补充规则:黑火药火炮(TL3-5)将伤害除以6
