  Iltharanos
  BACKGROUND
  The Challenger-class light cruiser was designed to explore the benefits of the vertical stack arrangement of warp 
  nacelles. While the ship proved adequate in all respects, the unusual warp configuration did not confer any significant 
  advantages over the more standard configurations of the time and Starfleet did not pursue the the design avenue further.
