Admiral Ross’ ready room was a spacious office directly connected to the ship’s bridge, where he could host private meetings with visiting dignitaries or other commanding officers from the fleet.
The admiral’s desk occupied the center of the room, behind it was a large illuminated logo of the United Federation of Planets, visible on any communication the admiral would engage on from the room. The wall to the left of the desk featured a large LCARS display with a direct uplink to Starfleet Command, as well as a model of Cerberus. Between this wall and the desk was a door leading to a small lavatory.
