Later that year, the location of the
Emden was labeled in the star chart for the " Operation: Retrieve" command briefing. This star chart was seen in the office of the Federation President on Earth. For "Operation: Retrieve", this starship was named as one of the ships on station in
Sector 21166-8. ( , Star Trek VI: The Undiscovered Country set artwork)
Background information Edit
On the plans, the Emden was represented by the silhouette of a refit Constitution-class starship.
An unseen element from the Operation Retrieve charts included a list of starships, their registries and their commanders. According to this list, the Emden was commanded by C. Thomas; named after that film's photographic effects editor Robert C. Thomas. Emden's last reported location was in Sector 21803. 
The Decipher roleplaying game supplements stated that this vessel may be a Ranger-class starship.
The Emden might be named after one of several German navy ships of the same name, which were, in turn, named after the city of Emden.
