This fully illustrated Star Trek: The Official Starships magazine covers the Klingon Augment Ship. In the episode 'Affliction' genetically-engineered Klingon augments use a Klingon attack ship to mount a raid on the Enterprise NX-01. The ship was designed by John Eaves, who was originally told it shouldn't be instantly recognizable as a Klingon ship. As the design evolved it became clearly Klingon but it is one of the smallest Klingon ships we ever saw.
