Many of these templates are named such that they are compatible with https://nws-online.proboards.com/thread ... -pack-rtw3, except in a few cases where I wanted to change those ships specifically (e.g. BC4U0).
The nations included are the US, France, Germany, Japan, and China. Only the US is in a state I'd call finished, with France, Germany, and Japan currently at era 6, and China technically existing. Each nation is stored in its own folder and so can be added individually as you like.
Many of these templates are vanilla in origin, or generic templates that I have assigned to the nation matching the style used in the template, for which I have rationalized and re-balanced armor and ammo to be more effective, with an aim of keeping weight within the same general area.
Also, bear in mind that some templates are not feasible to create in their era without a speed table mod like https://nws-online.proboards.com/thread ... ships-july, the specific one I used while creating them is the New Speed Mod found on the RTW discord by Metesky.
Some templates have equipment from https://nws-online.proboards.com/thread ... -equipment and RtW 3 IRL Jet Equipment Pieces (found on the RTW discord by yobeefjerky), but these are mostly planes and don't detract much from the templates if they are missing.
