Several commanders in Starfleet competed to be chosen as the first to fly the NX-Alpha in the effort to break the warp 2 barrier. After several weeks, it became clear the competition was down to Jonathan Archer, Henry Archer's son, and A.G. Robinson. Although Archer had logged more flight hours in the simulator, Commodore Forrest selected Commander Robinson.
In 2143, Commander Robinson flew the NX-Alpha while Commander Archer monitored from Starfleet Command. Initially, there was an imbalance in the power systems, causing them to keep the NX-Alpha in orbit. When they finally gave him the okay, Robinson jumped to warp 1.
The ship successfully attained warp 2, but the power systems began rapidly overloading. Command ordered him to drop to sublight, but Robinson believed it could be pushed a little further. After attaining warp 2.2, the NX-Alpha broke up just outside of orbit of Jupiter. Luckily, Robinson was able to eject in an escape pod that was retrieved and brought back to Earth.
Afterward, the Vulcan Advisory Council insisted on pausing the program until the Human scientists could figure out what had gone wrong, and run more simulations. Robinson told the inquiry that it was a design flaw in the engine, although Commander Archer and Lieutenant Charles Tucker asserted that it was actually pilot error. The results of the NX-Alpha's mission eventually led to the unapproved flight of the NX-Beta. (ENT: "First Flight")
