Is this about the weapons and other equipment, or is this about the hull design, or both? What I think you are after is the actual equipment layouts we use. This makes a lot of sense to me. I use default war ship design a lot, but have been putting them on my own hulls. That won't do you any good. If I have created specific use ships on non-standard hulls (Workshop downloads) is that any use? Can you discard the hull information?
Sorry for the spray of questions, but I know a lot of people fuss with their ships in different ways and I wanted to help understand which submissions would be the best use of your time.
I actually spend more time outfitting special purpose ships like constructors than I do warships. I have seen the AI use a few of those designs. Since they use the strange hulls when I design them, the AI copies the strange hulls as well. This can be a surprise to someone in MP mode, strange twinkling and twirling things flying across the map. It's fun, but I expect that is not the part you are after. However, a great many of the community have a range of constructor designs that we find very useful, especially as default designs for starbase upgrades. Are you interested in civilian designs as well as war ships?
Great project. I have admired this ability of the game from the outset. One of the best things to do for an AI is give it the equivalent of actual experience to apply its algorithms to. Databases are as powerful as starbases, maybe more so.
