Vance Haden

Vice Admiral Haden was a 24th century Starfleet Command flag officer based at the starbase on Lya III.

In 2366, Haden was Starfleet's liaison officer between the Federation Council and the USS Enterprise-D regarding the defection of Romulan Admiral Jarok. (TNG episode: "The Defector")

The next year, he confirmed to Captain Picard, that Cardassian allegations of a Starfleet starship attacking Cardassian installations were indeed true and that this ship was the USS Phoenix under Benjamin Maxwell. He ordered Picard to stop Maxwell from provoking a new war at all cost. (TNG episode: "The Defector")

In 2370, Captain Declan Keogh of the USS Odyssey was imagining what the court martial of Major Kira Nerys and Lieutenant Jadzia Dax was going to be like after they disobeyed his direct order and apparently helped the Bajoran terrorist Orta. In Keogh's mind, Admiral Haden served on the tribunal and delivered the guilty verdict. (The Brave and the Bold: "The Second Artifact'')
