Challenger (NX class)

Background
Challenger was the third NX vessel to be constructed, named after the NASA orbiter. Originally, no future plans were in place for the construction of more NXs, after the construction of the VX] prototype Dauntless began. However, when the Terra Prime attack came on the [[Warp Seven Complex in Febuary 2155, it was estimated that a further six months would be required to complete Dauntless, and two further NXs were put into production instead. The first of these, Challenger was completed in October 2155 and launched on September 6th of that year.

First Mission
When contact was lost with vessesl near to the edge of explored space, Challenger was sent to asertain what had taken place. Challenger was able to recover the only surviving ship, Valhalla (TSI-03) and return to friendly space. ('CHA: Valhalla').
