The USS Dauntless (NX-01-A) was a starship designed by Arturis of Species 116 during the 2370s. It employed quantum slipstream drive technology, which allowed it to go higher than the standard Starfleet warp scale. Although created by alien technology, the ship was modified to resemble Federation starships on the interior and exterior by the means of particle synthesis. In mid-2374, the crew of the USS Voyager was introduced to the Dauntless-class prototype.
