An Excelsior-class Federation starship named after the murdered Klingon chancellor, used by Vice Admiral Nechayev as her flagship during the Borg incursion of 2369.
The USS Gorkon was an Excelsior-class starship named in honour of Chancellor Gorkon, the Klingon leader whose peace initiative led to the Khitomer Accords. That Starfleet named a ship after a Klingon shows how far relations had moved in seventy years.
The ship appears in Descent. After a Borg vessel of unfamiliar design attacks the outpost at Ohniaka III, Vice Admiral Alynna Nechayev arrives aboard the Gorkon to take charge of the response. She places the Enterprise-D at the head of a three-ship task force and uses the visit to reprimand Captain Picard for returning the drone Hugh to the Collective unharmed.
The Gorkon is shown using the standard Excelsior studio model.
