Building:Covert Airfield

The Covert Airfield is a GDM building that can produce aircraft, but unlike regular airfields, stays underground.

Usage
The airfield was used to launch aircraft without being detected. It played a major role in fighting enemies because airfields could be placed under the battlefield and release swarms of aircraft without the enemy ever figuring out where it was. As a result, the GDM won many battles by air and were feared by the rest of the GDM's enemies.

Production
The airfield is responsible for making some of the GDM's most powerful aircraft, such as the Helicopter-9000, the aggressor, the gunship, and a lot more. Strangely enough, interplanetary carriers can be produced, despite their enormous size.

Trivia
-The airfield could produce more than a billion aircraft in a year. -The only part visible of the airfield is the hangar bay.
