A small Starfleet vessel under Captain Ramart that rescued Charles Evans from Thasus in 2266 and was destroyed by the boy's mental powers shortly after handing him to the Enterprise.
The Antares is a survey or cargo ship with a crew of about twenty. In the episode Charlie X it has picked up seventeen-year-old Charlie Evans, sole survivor of a crash on Thasus, and transfers him to the Enterprise for passage to Colony Alpha V. Captain Ramart and his navigator Tom Nellis praise the boy at length and seem oddly eager to leave.
Later Ramart calls the Enterprise to warn Kirk about something, but the message breaks off and the Antares is gone. Charlie admits he made a warped baffle plate on its energy pile disappear because the crew were not nice to him. The loss is the first sign of the powers the Thasians gave him. The ship was not shown in the original broadcast and was given a design and registry in the remastered edition.
