Star Trek, Main Bridge image - FEARIUN

On Starfleet vessels, the bridge was usually located on Deck 1, on top of the vessel's primary hull. The bridge was the nerve-center of every starship, and it was manned by the top officers of each department except for Engineering and Medical. There was typically an engineering station that the Chief Engineer could use when on the bridge, as well as science stations that the science officer or chief medical officer could use.
