and the NX ALLIANCE
In the first timeline, the NX ALLIANCE was the prototype of the Galaxy class design. It failed miserably leading to a major design overhaul.

In 2365 the ship was given a major refit. The ship was flung to another galaxy where Renalt had no choice but to plot a course toward home. However, while helping another ship, the ENTERPRISE was destroyed. This is when Q changed the timeline.
