The "USS Dauntless" was an alien starship disguised as a Federation Dauntless-class starship that was in service to Starfleet in the late 24th century. Allegedly, the Dauntless was the prototype for its class of starship.
In mid-2374, while still stranded in the Delta Quadrant, the USS Voyager received a transmission from Starfleet Command via the ancient Hirogen communications network. Although the message contained a number of unencoded personal messages, there was also an encrypted file that the Voyager crew was unable to open.
On Stardate 51978, Voyager encountered an alien named Arturis who had a gift for translating languages, both verbal and visual. He easily decrypted the mysterious message, which gave a set of coordinates near their current location. Upon arrival, the Voyager crew discovered the Dauntless.
Incorporating technology called a quantum slipstream drive that promised a faster trip home, the Dauntless proved to be an elaborate trap set by Arturis to arrange for the Voyager crew's assimilation by the Borg. Arturis's race had been recently assimilated by the Borg, and Arturis blamed that event on Kathryn Janeway's short-lived alliance with the Borg against Species 8472.
