Situation room

From Memory Alpha, the free Star Trek reference.

The situation room was a small section located at the rear of the bridge aboard NX class starships in the 22nd century.

The room was a precursor to the briefing room aboard Federation vessels, where senior officers could hold discussions on subjects such as the progress of a mission. It was marked by several computer displays and stations (including the environmental controls) and a small table with swing-out chairs built into its structure. (ENT: "Broken Bow", "Chosen Realm")

The room was also accessible through a doorway located on the starboard bulkhead. (ENT: "Acquisition")

When it was not used for briefings, the situation room was often manned by several crew members. (ENT: "Zero Hour")

In the mirror universe episode "In a Mirror, Darkly, Part II", the NX-class ISS Avenger did not have a situation room, but a wall and a bank of computer monitors in its place.

The design for the situation room aboard Enterprise obviously took cues from the aft section of the Defiant from DS9, also designed by Herman Zimmerman.

While there was never any on-screen indication as to where the situation room door led, blueprints of the NX-01 suggested that it led to airlock access.
