ISS Enterprise (NCC-1701)

The ISS (Imperial Star Ship) Enterprise existed in a parallel universe that is somehow connected to ours (referred to by some as the "mirror universe"). During an ion storm in 2267, a landing party from the USS Enterprise was transported to this mirror starship.

The mirror Starfleet's ISS Enterprise was almost identical in configuration to a Federation Constitution-class heavy cruiser of the 2260s, the USS Enterprise, and bears the same registry, NCC-1701. However, many minute details distinguished it such as the dagger emblem of the Terran Empire painted on the doors, and the posting of armed soldiers in the corridors.

The ISS Enterprise was the flagship of the Terran Empire. During her service life, the Enterprise had four commanding officers, Karl Franz, Christopher Pike, James T. Kirk and Spock.

James T. Kirk seized control of the Enterprise in 2264 after assassinating Pike with an unusual alien device known as the Tantalus field. One of Kirk's first actions as captain was to quell the uprising Gorlan people who wished to secede from the Empire and become part of the Klingon Empire.

In late 2266, the Enterprise made first contact with the First Federation vessel Fesarius, where the Enterprise crew were threatened with death by Commander Balok. However, Kirk managed to bluff Balok into believing that they were peaceful, and then launched an all out assault on Balok's small pilot vessel.

Shortly after, the Enterprise engaged and destroyed a rogue Romulan Bird-of-Prey which had crossed over the Romulan Neutral Zone and destroyed several Empire bases. Following this, the Enterprise led an assault force which destroyed several dozen Romulan outposts on the other side of the border.

The following year, the Enterprise engaged a Gorn warship attacking the Empire base on Cestus III. Unfortunately, the Gorn ship was more than a match for the Enterprise and she was able to escape back to her homeworld. Shortly after, war was officially declared between the Gorn and the Empire.

A few months later, the Enterprise was dispatched to Janus VI to ascertain while production from the mines had been down lately. Kirk and his landing parties then helped in the decimation of the Horta species by destroying the Mother Horta and all of her eggs.

Towards the end of the year, the Enterprise sought to extract dilithium from the Halkans' planet, leading to a "crossover" incident with a counterpart Enterprise in the parallel universe of the Federation. Enterprise first officer Spock seized command afterwards as a result.
