Nyota Uhura

Lieutenant Uhura: "There's Klingons on the starboard bow!"

Lieutenant Nyota Uhura served as chief communications officer for the Constitution-class starship USS Enterprise during its five-year exploration mission and retained the post almost continuously until the ship was destroyed. She continued to serve on the Enterprise-A until that ship was decommissioned.
