无聊架空--轻型8寸巡洋舰

洗甲板工 · 发表于 2024-10-7 23:25

根据这帖 https://www.warships.com.cn/thread-7101-1-1.html 和其他贴，公认巡洋舰要8寸主炮，然后七千吨是理想的排水量（见李安特级）所以问题是两者可否共存？我试了一下，用了 2x3 的设计，在优化了一下舰体，把标排砍到7190吨。动力方面，70000 shp 可以跑 31.5节，假设 42.8 shp / ton 输出，SPS 高估了540吨，我在杂项重量减回。装甲可以堆到弹药库4寸，主甲带2寸，甲板2寸，是有点脆脆...... 为了减重，架空了 2x2 4.7" / 40 高炮（基于纳尔逊级）。最后预留了一架水上飞机的重量。

大佬们可以在这基础上继续改良
