Will these spawn on.. pertam?

This looks awesome! Glad I just found it.

hmm...

I'll continue looking for anything out of the ordinary, but so far it is a fun little npc faction to add pain in the game. Look forward to seeing possibly more enemy types (aircraft carrier of sort with water mod? lol)

If I am correct about the Documentation, the bases should only spawn on land. I also have noticed issues with the turrets on worlds with high mod counts. I have a feeling this is a strange keen bug.

Have noticed one thing: NPC grids with those custom turrets never seem to track or fire at hostiles near them. Besides the things in the hangars, the base is easy to take over

This will make a fine addition to my suffering. If one is using the water mod (blessing of a mod), what is the chance that one of these structures will spawn under the waves? Also will we be seeing more types of aircraft in the future?
