Nomad (or Nomad MK-15c) was an interstellar space probe designed by Jackson Roykirk and launched from Earth in the year 2002 with a mission of seeking out new life. It was a prototype, and the only one of its type built.


Nomad in the mirror universe.

In flight, Nomad was damaged by a meteor and lost contact with Earth. It later merged with an alien probe called Tan Ru, resulting in a powerful new machine which, due to scrambled programming, destroyed anything that was perceived as imperfect.

Nomad was rediscovered by the USS Enterprise in 2267, after it had destroyed the inhabitants of the Malurian system. Mistaking Captain James T. Kirk for Jackson Roykirk, Nomad allowed itself to be brought aboard Enterprise. There, it erased the memory of Lieutenant Nyota Uhura, and killed Lt. Commander Montgomery Scott -- although Nomad was able to then "repair" him. Eventually, Kirk managed to convince Nomad it was imperfect itself, and thus leading it to self-destruct. (TOS episode: "The Changeling", ST website:

The episode only referred to Nomad as having launched in "the early 2000s". The specific date of 2002 comes from other sources.

Captain Anne Gauvreau claimed to have recovered other Nomad probes in deep space, which she in turn sold to the Smithsonian Institution. (TOS novel: Prime Directive)

As it is stated canonically that only one Nomad was built and launched, Gauvreau likely either misspoke, or misidentified her discoveries.
