There is not a guide, If I had time I'd write one.
But my comments here would be: you don't need a navy necessarily. If your looking for just gaining navy experience then, sure. But, if you just desire a distant country; you can just use ground forces.
You can send a airport construction team up to 12000 distance, and then just conduct the war as a ground war after you lift in the units along with supply units
For the the record I did once set sail to conquer a country with the navy, and still ended up sending an airport construction team to build an airport. This allowed the airdropping of heavy ground weapons. It was just cheaper and easier.
For C3s I don't think a navy is useful. For pvp, it allows you to bring in support for your ground troops. So you'd send the navy to back up the troops you airlift. Also the guided missiles and cruise missiles are very good for destroying defensive positions.

Yea please do that would be wonderful. I am trying to just learn the mechanics and such a navy is expensive but wanted to get more info before I go in. What do you do if it’s more than 12k
I posted the log for that navy campaign on the chat channel. Maybe you can glean something from it.
I think I just ran out of navy fighters, and had to go more conventional at the end. But I think the navy fighters were very effective in general.
I uploaded it to the discord general channel.
