The Centaur-class is an Excelsior-class variant built at the Utopia Planitia Fleet Yards in the mid 24th century. They have an Excelsior saucer and warp nacelles without an engineering hull. While the Centaur was created from Excelsior parts, its design looks similar Miranda-class ship. It's not known if there are other ships of this design, or that the Centaur is a class and not just a war-time kitbash.

The name Centaur is not the official name of this design, instead it is listed as an Excelsior-class variant in the DS9 Technical Manual. The name is taken from the only known ship of this design. The registry number comes from the Star Trek Fact Files. The DS9TM shows an incorrect image of the Centaur, this is the correct view supplied by Ex Astris Scientia.
