The NX-Delta was a prototype vessel used in the NX Project in an effort to test and refine Henry Archer's warp 5 engine design.
In 2145, over twenty months after Commanders Jonathan Archer, Henry Archer's son, and A.G. Robinson's illegal flight in the NX-Beta, the NX-Delta, piloted by Duvall, became the first Human spacecraft to break warp 3. (ENT: "First Flight")
