Grineer Galleons are the second tile set for Grineer after the Grineer Asteroid Base. The Grineer Galleon has a rather dated atmosphere, with grimy hallways and large docking bays to hold and maintain smaller vessels. Dark and foreboding in most areas, the Galleon is mostly lit by the light of the stars shining through the windows.
Interestingly, while the Corpus Ship's navigation console displays a hologram of its exterior, the Grineer Galleon's navigation console depicts a spiked sphere that is notably similar in appearance to the mines being dispensed in one of the possible tiles.
Two Firbolg shuttles can be found suspended in the Hangar tile, and another is used as the escape shuttle by Capture targets and Kavor survivors.
On Railjack missions, the full length of a Grineer Galleon's exterior is approximately 4080m.
