...With coordinated fire from the Athens and the Malta, nothing's getting past this battle cluster in one piece.
Athens Station (HCS: ODA-144) was a UNSC Orbital Defense Platform in Geosynchronous Orbit above Earth. It was so named after the city of Athens, Greece and maintained geosynchronous orbit over Earth. It was in the same battle cluster as both Cairo Station and Malta Station.
During the Battle of Earth, the Athens was destroyed right after the Malta and in the same fashion: Covenant boarders placed a Antimatter charge on the station and then withdrew prior to its detonation. This of course led the human forces on board to believe they had beaten the Covenant back.
