Instead of the two-story gyms both small and medium warships are allotted, Large Warships and Space Stations are given three story gymnasiums. The first and bottom-most floor is the main exercise room with a variety of weight/exercise machines bolted down to the floor. There are also dozens of storage units that hold free weights which allow for more variety in exercise regiments.

The second floor is actually just open space for the most part. This floor is allotted for martial arts sparring and training with six official sparring rings and a variety of Mats that can be found in storage areas along the walls. While the third floor is much like the second floor of its smaller counterparts, that being a railing-enclosed jogging track that extends 4 meters into the center of the Gym.

A First Aid Station is located near the entrance.
