For the beginning of Campaigns and Adventure Mode, a reliable ship at a 50,000 material cost seems like the most balanced way to balance offense and defense. While aircraft can be very cheap, they also have limited weapons options.

Surface ships and subs allow the concentration of firepower, but at the same time you need to quickly deploy a large number of ships quickly to capture territory, too.

Figured I would try to get a list of tutorials and guides all linked together for people too be able to design ships and weapons systems for the early game. The learning curve is hard for new players, so hopefully getting a list of guides and tutorials aimed at ships and subs that are both cheap and powerful together will help the newer players, and as a refresher for older players that haven't built small craft in a while.

Making this a community project from the start, so please feel free to help create the list.
