In 2293, the Enterprise-A and her crew were tasked with escorting Chancellor Gorkon of the Klingon High Command to Earth to begin peace talks following the economic and energy crisis suffered by the Klingon Empire after its moon, Praxis, exploded. After a splinter faction of those resisting the imminent Federation/Klingon alliance successfully assassinated Chancellor Gorkon while under the Enterprise’s escort, the ship fled to Khitomer where a peace conference was being held. There, it withstood intense battle damage from an attack by a Klingon Bird-of-Prey commanded by the rogue General Chang. Defeating Chang and arriving at the conference in the nick of time, the Enterprise crew thwarted an assassination attempt of the Federation President and the peace talks were successful. Shortly after the incident, due to its age and battle damage sustained, the Enterprise-A was decommissioned.
Sometime prior to 2293, the bridge module of the Enterprise was once again swapped with an updated design. The general layout was the same, with the captain’s chair and helm console in a recessed command pit, the main viewer in front, two turbolifts at the sides, and bridge stations around the perimeter. Adopting a more militaristic aesthetic, the carpets used in the previous bridge module were removed, giving way to austere metal-plate flooring and battleship-gray walls.

The U.S.S. Enterprise-A was introduced in a previous film, Star Trek IV: The Voyage Home, and was the same filming miniature used previously, but with new registry decals applied by the Industrial Light & Magic (ILM) Model Shop.

For The Undiscovered Country, director Nicholas Mayer wanted the bridge to look like a busy military command center. To achieve this, production designer Herman Zimmerman used darker colors, metallic flooring, and provided multiple chairs on most of the stations for more crew members. This bridge in particular was also distressed quite significantly, to indicate how old and worn the ship was meant to be.
