Having the AI create everything for you in a new game seems to prioritize building an army over a navy. Only troops were built in several games, but plenty of templates for ships were made.
When making ships, if you delete all/most of the components on the ship a warning text will appear saying "freighters require at least one engineering space."
You can design size 0 fighter pods. When you design the pods with size 0 they are still counted as 1 MSP.
A size 0 autocannon pod still does damage (mine says 30, not sure if this is base or not).
Damage on autocannon pod does not go up with MSP size but armor pen does, not sure if this is intentional or not.
When you put these size 0 pods on a ship the game says that there is "0x fighter pod" in the ordnance layout (probably working as intended but still weird).
Addition: When making size 0 pods the bombardment and air-to-air pods show the missile specifications rather then the fighter pod specifications. Autocannon size 0 shows fighter pods specifications
