The Hangar Bay (referred to as Federation Landing Site by Aurora Unit 242, and Federation Outpost in the ship destination map) is a room on the planet Bryyo, in the Bryyo Cliffside region. It was once used by the Galactic Federation to land on Bryyo. Samus must use this place to upgrade her Gunship and arm it with the Ship Missiles necessary to advance to Bryyo Thorn Jungle. This room also contains a Energy Cell, located in a balcony area high above the room.
