We fill in more starships that have been mentioned in the Continuing Mission continuity. The U.S.S. Archer (NCC-52991) is a Steamrunner-Class starship that you can use in your campaign. It has the mission profile of Pathfinder and Reconnaissance Operations. It was mentioned as the ship of Heyta, Xindi-Primate, but use it however you like.
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 (Federation or Klingon) rules will be used (with perhaps a few special exceptions, such as the spaceframes from the Command Division supplement).
