This is an interior shot of the bridge of a typical Terran Protectorate capital ship, in this case the Hastings-Class Battlecarrier.
On the far left is the communication station, which handles internal and external transmissions.
In the center of the room is the command station, where the captain or OOD (officer on duty) sits. The captain has access to secured comm channels and can call up the screen from any other station on the bridge.
There are three helm stations. On the left is operations, which monitors mission status, allocation of ships resources, manages internal security, etc. In the middle is the actual helm control, which handles the actual flight of the ship. On the right is the tactical station, which oversees weapons systems and tactical information.
Just visible in the bottom corner is part of the bridge engineering station (more on that in a following image).
This bridge was assembled from several other sets, most of which I've retextured to give it a uniform, military look.
Enjoy, and let me know what you think
