Challenger (NX-03)

Challenger (NX-03) was an NX-class starship in the service of the United Earth Starfleet in the mid-22nd century.

As of Thursday, May 22, 2155 Challenger was still under construction in the skies above San Francisco. On that date, while on an assignment to patrol Earth Cargo Service trade routes, CaptainJonathan Archer of the Enterprise (NX-01) pondered whether he might be able persuade Starfleet to Challenger into service, re-christening her the Sisyohus, to take on his less than engaging mission. It was launched circa August 2155, alongside the Discoverey.
