When Starfleet later returned to the Delta Quadrant as part of Operation Delta Rising, the Dauntless class was revived as a genuine Federation starship. As part of the operation, Starfleet built a real USS Dauntless (NX-01-A) and launched it in 2410. The registry was later amended to NCC-47700. (STO video game: Delta Rising) In the 26th century, the Dauntless was part of the fleet led by the USS Enterprise-J into the pivotal Battle of Procyon V, against the Sphere Builders and their Temporal Liberation Front allies.
