至于说身管一致也是不对的,你看一下乔五炮神下面的注释,有的14寸重80+吨,有的就重90+吨,这个比较特殊 ...
The weight in the table above is for guns No. 91 to 136 which had the altered breech ring design. Guns No. 51-90 weighed 79.588 tons (80.865 mt). In addition to these weights, a balance weight was attached near the breech in order to move the center of gravity closer to the turret face plate. This allowed a higher elevation without having to deepen the gun wells, thus reducing the size of the gunhouse. With the balance weight, guns No. 91 to 136 weighed 91.488 tons (92.956 mt) and guns No. 61 to 90 weighed 90.588 tons (92.042 mt).
-----------------------------------
不知你对balance weight怎么理解——我觉得与身管强度无关,身管重量的差距就在这里
