In that year, the Centaur mistakenly attacked a Jem'Hadar attack ship being commanded by Captain Benjamin Sisko for a covert mission. The Centaur pursued the attack ship into Dominion territory before being chased off by three additional Jem'Hadar ships. (DS9: "A Time to Stand")
The third edition of the Star Trek Encyclopedia (3rd ed., p. 591) gave no registry number in its entry about this ship, although NCC-42043 was used in the Star Trek Fact Files, Star Trek: The Magazine Volume 3, Issue 6, p. 30, and Star Trek: The Magazine Volume 3, Issue 9, p. 36. The shooting model itself used that registry, but featured the name USS Buckner (illegible on screen.)
Many years later, there was a side view of the Centaur in the Star Trek Encyclopedia (4th ed., vol. 1, p. 127). The ship bore the registry NCC-42043.
A model of the Centaur was released as an issue of the Star Trek: The Official Starships Collection.
The Centaur and its crew were featured in the Star Trek: The Dominion War novels Call to Arms and Sacrifice of Angels. The vessel was believed lost in Operation Return, as Captain Reynolds recorded a captain's log in the event the Centaur was destroyed. Reynolds survived, and retired several years later.
