Fleet composition question
Hi I was wondering what fleet composition Germany is scripted to build on historical mode with this mod? In vanilla Germany barely builds any Submarines compared to real life Germany in my playthroughs. In real life Germany's WW2 fleet was literally 90% Submarines. They build a huge amount.

There are several stages of Germany's naval production.
1. Before 1938, mostly light surface ships and small amount of heavy ships, a moderate number of submarines.
2. After 1938 but before 1941 (at peace), submarine production increases 4 times
3. At war with Britain, a sharp decline in heavy ship production, all industiral capacity shift to submarine and destroyer, with a liitle distributed to cruiser.
4. Britain capitulated but has war with US, back to build a large surface fleet
5. At war with any major but at peace with UK and US in late game, a balanced surface fleet
6. At peace in late game, a balanced surface fleet

Would it be possible to make separate smaller submods just for the AI naval production strategies? Because the vanilla AI naval production is really bad/goofy. It would be nice to have better AI naval production in the vanilla game. The problem with big overhaul mods like this is that they are not compatible with a lot of other mods.

I believe this is one of the best naval ai mods

It changes too much for me to use it. It changes ship design, boosts AI production, adds Dockyards etc. It's not just an AI mod.

Can you explain the AI fleet composition for the other major nations in your mod?

It's a bit hard to describe that in a few words. But typically, the production can be split into following stages:
-Early: 1936-1938
-Rearmament: 1938-1940
-WWII: 1940-? (Most countries have historical enemies, they will stick to historical production strategy before the enemy is defeated)
-Post-war: After historical enemy surrenders
-WWIII: At war with majors after stage 3
There will be some differences between nations, some countries have finer division of production strategies, some don't.

I find that if I want a good AI to fight, I have to use tag switching and sometimes build it myself. (Using the "it" command to instantly produce all ships under production, having previously added construction of historical/good-quality warships for me to do battle with. Since this requires unpausing, definitely disable AI for your tag before switching.) ...And then I sometimes have to disable the (usually British) AI, manage its fleets myself, and thus ensure that my high-quality forces have high-quality enemies to engage. It's a lot more work, but it's either that or get bored. Just my two cents.

AI is a pain to modify, but I heard playing this mod in MP is gonna be a hyper thrill. Guess only human can give you such feeling that you need to do more strategic thinkings.

I am talking to a Dev and am going to make a Suggestion thread about the vanilla HOI4 AI naval production strategy. The vanilla AI is really bad in this regard especially in terms of historicity and immersion because it mostly just builds Light Ships on top of cancelling a bunch of Heavy Ships that are already under production at game start.

I already made a thread about your German naval AI production strategy. Please post explanations for the rest of the nations' AI naval production strategies so I can make a thread and show the Devs.

Where are the AI fleet construction strategy files found?

I am finding it hard to understand the code in common/ai_strategy. If you can find the time to post the naval production stages of the other AI countries I would appreciate it. I actually think it would make a really good standalone mod too.
