ISS

AT: "mu" Template:Disambiguate

ISS, short for Imperial Star Ship, was the designation given to space-faring ships of the Terran Empire and Terran Resistance Forces in the mirror universe. (ENT: "In a Mirror, Darkly, Part II")

The ISS Avenger dedication plaque is where the meaning for ISS comes from, as in Imperial Starship Avenger. This "mirrors" the meaning of USS, United Starship.

The use of ISS as a prefix for Imperial ships was already in use by the 22nd century, where ships of the Template:ShipClass were designated with the ISS prefix. (ENT: "In a Mirror, Darkly", "In a Mirror, Darkly, Part II")

• ISS Avenger NX-09

The Terran Empire was still using the ISS prefix for starships in the 23rd century. (TOS: "Mirror, Mirror")

• ISS Enterprise NCC-1701

After the fall of the Terran Empire to the Klingon-Cardassian Alliance, the use of the ISS prefix wasn't used of vessels like the Terran raider, but was resumed when the Terran Rebellion build a Template:ShipClass starship based on specifications "acquired" from the prime universe.
