Chief Ross was a female Human Starfleet enlisted crewmember in the 23rd century. She was in the engineering and maintenance branches of the Operations division. She was an engineering technician. In the mid-2270s, she served aboard the USS Enterprise under the command of Captain James T. Kirk.
She overheard Captain Kirk issue Starfleet Order 2005 to Chief Engineer Scott in his attempt to prevent V'ger from destroying Earth. Horrified, Ross asked Scott why the captain ordered the self-destruct and whether or not it would successfully destroy V'ger. (Star Trek: The Motion Picture)
