Tide of fusion ships: 关于RN旧主力舰改造的系列想定

LeSoleil

纳尔逊的提速方案

目标为：标准排水量35kt；96000马力；4轴；28节

LeSoleil

最近看Tzoli根据弗里德曼英战绘制的纳尔逊38~39现代化改造方案，重新拾起这个老帖。


一个发现是，按照条约的话，老舰的改造除了法意之外，不能大改除甲板和防雷外的部分：

(d) No retained capital ships or aircraft carriers shall be reconstructed except for the purpose of providing means of defense against air and submarine attack, and subject to the following rules: The Contracting Powers may, for that purpose, equip existing tonnage with bulge or blister or anti-air attack deck protection, providing the increase of displacement thus effected does not exceed 3,000 tons (3,048 metric tons) displacement for each ship. No alterations in side armor, in calibre, number or general type of mounting of main armament shall be permitted except:

   (1) in the case of France and Italy, which countries within the
       limits allowed for bulge may increase their armor protection and
       the calibre of the guns now carried on their existing capital
       ships so as not to exceed 16 inches (406 millimeters) and
   (2) the British Empire shall be permitted to complete, in the case of
       the Renown, the alterations to armor that have already
       been commenced but temporarily suspended.


效力一直到36年底，然后伦二的替代条款：

Article 3
No vessel which at the date of the coming into force of the present Treaty carries guns with a calibre exceeding the limits prescribed by this Part of the present Treaty shall, if reconstructed or modernised, be rearmed with guns of a greater calibre than those previously carried by her.

可以看到幅度巨大的放松。日本人给老战列舰提速的改造也大多发生在34年底宣布退出华盛顿条约之后。换句话说这楼里在34年开始给纳尔逊提速大概是不现实的。

取而代之的是把37年投入现代化重建的QE和刚勇改建成高速战列舰的计划：



由于37年新条约对老船改造的放松，可以提供更多的改动。相比历史位面，改进主要在于重建更长的舰首以提供高速和更多浮力；动力出力提高到10万马力（按照对Warspite的改装，仅需3/4的锅炉舱、6台锅炉就能提供8万马力，而QE和刚勇出于配重考虑硬是安装了8座锅炉把空间占满）；对甲板的强化也可以更进一步（原本的弹药库加4寸、动力舱加2.5寸的计划仅用了617吨；如能提供更多浮力，则1000吨应该能实现弹药库5寸、动力舱4寸且同步强化穹甲的理想方案）。

目标是以34000吨的标准排水量（原版改造后约为31500吨）跑到28节，成为标准的高速战列舰。
