仅以我个人浅薄的理解，炮塔旋回部包含炮管、炮盾、炮架是没有问题的。三联155炮塔重量也的确如此。 双联140到底多重，nw上是这样写的，50吨和36吨都有出处，不过nw作者不太相信36吨的说法。 石桥三部分加起来不等于36吨，可能有另外的错误。楼主有没有单装140炮管炮盾炮架的重量可供参考？ 期待有大佬答疑解惑。
"Naval Weapons of World War Two" says that the twin mounts on the Katori class weighed 48 tons (49 mt) while the twin mountings on the other ships were 35.9 to 36.9 tons (36.5 to 37.5 mt). This data appears to be sourced from US Naval Technical Mission to Japan report O-47(N1). Campbell credits this weight difference to the Katori class having thick 5 cm (2 inch) shields versus 1 cm (0.4 inch) shields on the other ships, although shield thickness is not noted in O-47(N1). However, this weight difference and level of protection is not supported by "Japanese Cruisers of the Pacific War," which states that all ships had a 1 cm (0.4 inch) shield and weighed 49 tons (50 mt). This weight seems consistent with the single mounting at 20 tons (21 mt) as reported in this same source, as the single mounting was an open back type while the twin was a fully enclosed design. I also find it difficult to believe that the Katori class would have had such a thick gun shield as they were designed and built as training cruisers. These ships lacked all but splinter protection everywhere else, as thicker armor would have taken weight away from their primary purpose of training. For these reasons, I believe that "Japanese Cruisers of the Pacific War" is probably the correct source to use for these mountings.
