架空一战战列舰

架空背景：17世纪中叶农民军建立王朝，19世纪末20世纪初基本工业化，一战前工业总量世界第二，人均比沙俄略低，一战中崩溃，发生rev，1920年CISM取得civil war胜利。

初代无畏舰4艘，1909年开工，1912-1913年完工，一战中战沉一艘（与金刚级交战中Q炮塔被摧毁，火灾从提弹机蔓延至弹药库发生殉爆），civil war中一艘自沉（战后被打捞）。

20年代中后期，两艘残存舰经历修复和改装火控系统的改造。30年代初对打捞后闲置的三号舰进行大幅现代化改造，轮机舱和弹药库部位水平装甲加强至150毫米，拆除X炮塔，为改造轮机舱和水上飞机库腾出空间，增加半米纵深的防雷鼓出部（内置钢管以平衡水平装甲提高的重心），舰体内TDS纵深保持原先4米，内部增加隔板数量。
