Griphon

"The lofty fortress of Griphon is one of Medici's largest military airfields. During the Cold War, Di Ravello reluctantly loaned out Griphon to his Western allies, and a contingent of NATO aircraft called the base home during the days of the Cuban Crisis."

Griphon is a military airbase in Just Cause 3.

Description
It's a military airport built on the side of a cliff and entirely held up by high, reinforced concrete columns. There are two major runways, one placed above another, and there is always constant traffic of U-7 Dravecs and CS7 Thunderhawks departing, landing and flying round the perimeter.
