Advanced Construction Aircraft is a unit that builds most of the T2 economy and defensive structures.

In most situations when you get one, start from updating your metal extractors, geothermal powerplants and then make fusion reactors and advanced metal makers.

It has higher buildpower than its T1 version, and boosts your metal and energy storage by 50.

As an air constructor, it has the advantage of being able to quickly access all spots on the map. However, it has lower buildpower than land constructors.
