The International Space Elevator reaches 100,000 km (~62,137 miles) into the sky. A photovoltaic power plant is constructed at geosynchronous orbit to supply power to Usean countries below. No further design details are known.
Sometime before the Lighthouse War, Osea began building the space elevator in contested territory claimed by Erusea, despite the latter's protest. This event provided one of the catalysts that lead up to the war between the two countries. Following Erusea's declaration of war against the Osean Federation, Erusea captured the International Space Elevator for an unknown purpose.
- The International Space Elevator is the tallest structure in the series, surpassing the Gaiuss Tower in Ace Combat X: Skies of Deception.
