IJN对抗德梅因的架空设计----富士级
架空：二战在45年前尚未爆发，美国的德梅因级重巡洋舰将要入役。为了对抗8英寸机关炮的威胁，IJN提出在伊吹之后的新一代重巡计划。目的一：对抗德梅因级；目的二：护卫机动舰队。
要求一：火力压制德梅因级；要求二：六座以上98式10公厘高炮；要求三：航速33节；要求四：在标准作战距离上能防御美国8英寸超重蛋。要求五：要求尽量控制成本。
火力方案一：203/55三联装炮塔四座，新炮，射速6发/分。
火力方案二：203/55双联装炮塔五座，新炮，射速6发/分。
火力方案三：254/50三联装炮塔三座，新炮，射速4发/分。
火力方案四：356/45双联装炮塔三座，旧炮翻新，射速2发/分。
由于203/55需新设计，而且射速远不能和MK16相比，虽然方案一和二火炮数量都多一些，但被认为还是不能压制德梅因。254/50同样被认为时间上赶不上，而且一套新的弹药装备成本太高。而由于扶桑级和伊势级四舰和金刚四舰陆续退役，而它们的14寸主炮还能够满足要求，最重要的是成本低。但14寸炮还是经过了部分改进，主要是减轻重量和提高射速。
主炮确定后，以3座主炮塔前二后一为基础按最小排水量来设计。
定案：
主尺度：全长：212米，全幅：25米，满载吃水：8米，标准排水量：19000吨，满载排水量22000吨。
动力：同利根型，四机八炉，152000马力，最大航速33节，航程10000海里/18节。
火力：356/45双联主炮3座，每门炮备蛋100发，100/65双联高炮6座，三联25MM机关炮12座，无雷装。
雷达：21型一部，22型两部，13型两部。
水上机：弹射器一部，水上机3架。
装甲：水线170MM倾斜15度，水平90MM，主炮塔200MM。
布局：高干舷平甲板布置，上层建筑类似最上，水上机及弹射器布置在舰尾，六座100高炮中两座布置在前主炮后和后主炮前，其他四座布置在两舷。
建造：首舰在横须贺，2号在吴，3号在神户，4号在长崎分别在44年开工，45年底下水，第二批4艘开工，47年第三批开工，一共12艘。
由于富士级的开发，造价更大的超甲巡案中止。 成本肯定是完爆德梅恩的 55倍203炮无需重新设计
3年式20厘米炮除了1号和2号，还有个3号，就是55倍的203炮，当初准备给高雄级和妙高级的一艘（记得是羽黑）换装的。1931年试制完成，试验结果良好。后来因为预算紧张等原因，1933年计划终止。 Leon 发表于 2012-12-6 23:51 static/image/common/back.gif
成本肯定是完爆德梅恩的
主炮是现成的，动力装置也与利根一样，应该是比较廉价的方案，轻巡阿贺野也是捡的旧炮。 考虑国产化了的一式24cm加农炮如何？ chaimeng32 发表于 2012-12-6 23:56 static/image/common/back.gif

超甲巡完全是看到美帝有了阿拉斯加然后就一定要弄个对应的出来，就是搞出来成本那么高鬼子舍得装备吗？有着钱还不如造几条战列舰，全世界也就是美帝有钱搞这个。 owaii 发表于 2012-12-6 23:58 static/image/common/back.gif
还不如直接搞超甲巡。数量少点也没关系。
条约后重巡的大型化是趋势，而超甲巡从阿拉斯加的例子看应该会成本很高，不足以替换到寿的甲巡。 chaimeng32 发表于 2012-12-6 23:58 static/image/common/back.gif
受教了，356双联炮塔600多吨重，装上3座可行吗？
装三座可行。其实你可以看看http://www.warships.com.cn/thread-3559-1-2.html里面的设计，然后斟酌修改一下。
一式24厘米炮是法国士乃德造九〇式24厘米列车炮的仿制版——不过是陆军炮。海军要想弄来恐怕要费点事。不过性能是很不错的。54倍身管，弹重，初速1050，射程50120
作为海军炮的话，可以修改一下，加大弹重，减小初速和射程，提高威力。 考虑长管203也可以啊。 首先日本方面如何能精确得知8‘/55 mk16的射速？
其次即便知道了，那时再选炮，再造舰，服役时间要大大推迟
比较靠谱的炮还是203/55，比较靠谱的建造方案也是沿着日系重巡的路走下去 45年的时候旧的富士号战舰仍未退役

45年款少许加大吨位。我懒得改了。
日本海军的重巡的作战任务是夜战突破米国海军前卫部队，为雷击舰队创造雷击窗口。
所以说吗，要想啃开米国海军前卫部队，那么压力巨大，因为45年不止是什么德梅因，这都是次要的东西，米国海军前卫舰队很可能是一艘衣阿华搭配2-3艘阿拉斯加的阵型。
所以日本海军建造什么重巡，对战局影响不大，反倒是日本海军除了建造B-65超甲巡以外，还需要建造超超甲巡！而超超甲巡必须具备和衣阿华对战的能力。至少装备8门16寸以上口径的主炮，并且有完备的指挥系统！而速度至少超过32节！ 不用大廢周章, 建造金剛級改良型即可 风之旋律 发表于 2012-12-7 11:10 static/image/common/back.gif
