架空背景：17世紀(jì)中葉農(nóng)民軍建立王朝，19世紀(jì)末20世紀(jì)初基本工業(yè)化，一戰(zhàn)前工業(yè)總量世界第二，人均比沙俄略低，一戰(zhàn)中崩潰，發(fā)生rev，1920年CISM取得civil war勝利。

初代無畏艦4艘，1909年開工，1912-1913年完工，一戰(zhàn)中戰(zhàn)沉一艘（與金剛級交戰(zhàn)中Q炮塔被摧毀，火災(zāi)從提彈機(jī)蔓延至彈藥庫發(fā)生殉爆），civil war中一艘自沉（戰(zhàn)后被打撈）。

20年代中后期，兩艘殘存艦經(jīng)歷修復(fù)和改裝火控系統(tǒng)的改造。30年代初對打撈后閑置的三號艦進(jìn)行大幅現(xiàn)代化改造，輪機(jī)艙和彈藥庫部位水平裝甲加強(qiáng)至150毫米，拆除X炮塔，為改造輪機(jī)艙和水上飛機(jī)庫騰出空間，增加半米縱深的防雷鼓出部（內(nèi)置鋼管以平衡水平裝甲提高的重心），艦體內(nèi)TDS縱深保持原先4米，內(nèi)部增加隔板數(shù)量。
