Chief Ross was a female Human Starfleet enlisted crewman who lived during the mid-23rd century. She worked in the engineering and maintenance branches of the operations division as an engineering technician. In the mid-2270s, she served aboard the USS Enterprise under 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)
