Exterior Docking Hangar (外観ドッキングハンガー, Gaikan Dokkingu Hangā) is an area in the Frigate Orpheon in Metroid Prime. It is the first room explored in the game, the first in the Prime series, and the first Metroid room in 3-D. The Exterior Docking Hangar is where Samus lands her Gunship. To proceed into the frigate, Samus must deactivate two force fields by shooting a number of switches. The second set must first be activated by scanning an Interface Module. The hall that the door leads to is considered part of the hangar in the game's map.
