- 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 have been a Ranger-class starship.
- The Emden might have been named after one of several German navy ships of the same name, which were, in turn, named after the city of Emden.
