York-410-3, Germany Battleship ...

炮貌似嫩了点……
另外尾部还是搞个装甲盒保护下传动和舵机吧

20多放点嘛，又不缺空间，57少点都可以，主力舰防空要的是靠弹幕保护自己，不需要打下多少架敌机。

随手搞的习作，因为是拿起巡洋舰的基础做的，高炮部分没怎么去仔细做好，主要是看重炮击力，高炮就暂时忽略吧。呵呵。

41公分的主炮口径对德国来说好奇怪啊……

记得在米国海军统计里20MM击落敌机所占比率是很低的，127MM/40MM才是主力
20MM的最大作用是干扰鱼雷机的投弹------鱼雷机如果在500M内投雷是很可怕的，所以尽管20MM的有效射程只有1KM，但足够了
另外，20MM炮安装简单，可以临时添加

此船防护和火力不太相称，且浪费吨位严重
