The U.S.S. Challenger (NCC-71099) is a Galaxy-class starship that appeared in the Voyager episode “Timeless“, captained by Geordi La Forge in an alternate timeline (2390). It was part of the fleet that fought Borg Sphere 634 during the incident that saw the U.S.S. Voyager back to the Federation (“Endgame“).
The beta canon had variously placed the Challenger under the command of Simm (2371), Montgomery Scott (2383), Geordi La Forge (after Scott), but you should be free to use this ship as you wish. The ship was commissioned in 2370 but receives refits as the Galaxy ship class began in 2359. The Technical Test-Bed mission profile was selected since the beta canon indicated that it was assigned to the Starfleet Corps of Engineers.
The 2371 version is presented below. For other years, apply the necessary refits.
I include here a version created through the official Modiphius app. The EMH isn’t there but you can add it to this version.
Featured Starship articles spotlight established starships that you can use as a ship for players for immediate play (such as for a demo or convention game), or as an NPC ship in your campaign. Some are a natural fit with characters from the Featured Crew articles. Only Core Rulebook rules will be used (with perhaps a few special exceptions, such as the spaceframes from the Command Division supplement).
