A Kreetassan ship docked with Enterprise
A Kreetassan starship was a type of starship utilized by the Kreetassans during the mid-22nd century. These vessels had warp capability and were about 100 meters long.
In circa 2152, a Kreetassan starship, having accidentally and unknowingly picked up a symbiotic lifeform during a survey of the organism's homeworld, briefly docked with the Earth Starfleet ship Enterprise NX-01. The Kreetassan ship departed just as the organism entered Enterprise through a docking bay on the port side of the craft. Later responding to a hail from Enterprise, the Kreetassan vessel contacted the Starfleet craft, transmitting from the Kreetassan ship's bridge, and sent Enterprise the coordinates of the symbiotic organism's homeworld, to where the lifeform was safely returned. (ENT: "Vox Sola")
A Kreetassan ship was seen flying over the Kreetassan capital city later in 2152. (ENT: "A Night in Sickbay")
This vessel wasn't physically described in the final draft script of "Vox Sola". The ship's follow-up transmission isn't clearly depicted as being from the craft's bridge in the final version of the episode, or even from the Kreetassan vessel at all, although these details were established in the installment's final draft script. The Kreetassan craft's bridge was built as a one-wall set on Paramount Stage 8.
