One of the more unique designs of spacecraft, the Eymorg vessel was encountered by the USS Enterprise on Stardate 5431.4. The ship was of a totally unfamiliar design, comprising a tapered cylindrical main hull with a set of four much smaller hulls mounted around the midsection.

The ship was fitted with ion propulsion, which it could use to travel at faster than light speeds. Ion drive systems should only be capable of travel at sublight speeds, and the ability of the vessel to travel at warp speeds is a highly impressive feat.

The ship was also fitted with a transferral device similar in function to a Federation transporter. Its single crew member used this device to beam to the Enterprise bridge and incapacitate the crew. No obvious ship mounted weaponry or defensive technology was displayed during the encounter.
