Also known as: 国際軌道エレベーター, ISEV
A Space Elevator featured in Ace Combat 7: Skies Unknown. Officially known as the International Space Elevator, it was built as a peacekeeping effort on the Usean continent to harness solar energy from the atmosphere to power the globe.
Its name is the namesake of the main conflict of the game; the Lighthouse War, as the Kingdom of Erusea declared war on Osea over the structure, believing that its real intention was to enforce Osean hegemony on the continent.
