[2026.1] Type IX historical range corrections

Historically accurate fuel capacities for the Type IXA, IXC, and IXC/40, increasing their range for long-distance patrols. ✔ SAVE GAME COMPATIBLE you can add and remove mid campaign. Save game compatibility details This mod changes the value on your fuel tanks, and for campaign starts adds extra fuel so it's full. You can load saves with this mod running after you've disabled it and your fuel capacity will revert back to the vanilla 50,000. However, if you have already filled up your tanks beyond that I cannot "strip away" that extra fuel once the mod is disabled. When you use up that excess fuel you're back to the 50,000 limit. Why these fuel values? The base game uses the same fuel capacity values as the VIIC (as of 9 June 206). This is obviously an oversight by the devs. I took the VIICs fuel capacity as an accepted baseline, then multiplied it by the real world difference between the Type VII and Type IX ranges. Sources vary on this, if you're interested read the historical justification discussion thread. As a result your Type IX can now travel a lot faster - some of the ranges that are possible with 2 crew on the engine + 2 on navigation and the weather stations are not historical, but the game already allowed you to stack buffs on the Type VII that let you achieve ahistorical ranges, this mod sticks in line with vanilla's ruleset.
