It's 1943 (Machinery 23, Hull construction 20, Ship design 25), and I can't build any destroyers that would go over the limit of 33 knots speed and 2100t displacement. Above 2100t, no useable weight is added: it's ALL eaten by the growing machine weight. And above 33kts, machine weight becomes prohibitive even for this displacement. I know NWS are probably busy creating new things like guided missiles, but could there be a revision of these weight formulas sometime too? I really want to build Shimakaze  |

I don't know if that engine tech is "current", but that sounds like an issue. I mean, since the mid 1930s an average destroyers should do 38kn. A slow one 36 and fast ones 40+ knots, right? Unless those speeds reported for real world destroyers where all speed trial fantasies.
Does anyone know actual combat speeds of 1930s to 1940s destroyers?
How much horsepower do your DDs have? As far as I know all real world destroyer of that period had around 60 to 70000 shp.

As far as I know all real world destroyer of that period had around 60 to 70000 shp. The average for destroyers was about 36 knots and that required about 50,000 SHP. Now to gain more speed probably would require two more boilers and more turbines. To gain another two knots would require another 20000 SHP. This would require more machinery space and hence a long ship. The US Gleaves could do 37 knots with 50,000 SHP with a range of 6500 NMI at 12 knots. The Fletcher class did 36 knots with 60,000 SHP. Range was 6500 NMI at 15 knots. She could get the same range for three knots but she was a much better armed ship. As speed requirements go up, so does tonnage. |

Here is something interesting and a bit mathematical for you math geniuses. 02.07 Chapter 7.pdf (961.66 KB) |

Check out the realistic speed curves mod The one that comes with your 1936 starts mod? Maybe I'll try it for my next campaign, thanks Mine goes up to ~22000 tons because I adjusted stock values by calculation individually. I started running into issues at that point over the way the game processes data. There's a computer-generated one by someone else that goes up to 90,000 on the mod list, but I don't think it accounts for in-game weirdness |
