Airfield

“	Produces and houses Fixed-Wing Aircraft. Upgrade to increase air force capacity and access higher level units.	”
	— In-Game Description

General Information

The Airfield's description is misleading as the air force capacity does not increase when you upgrade it. It functions the same as the Barracks, War Factory, and Helipad. However, not all air units can be assigned as defenders.
