The Chief of Starfleet Operations was a high-ranking position at Starfleet Command on Earth. (Star Trek: The Motion Picture)

In 2375, the current Chief of Starfleet Operations granted special dispensation for Benjamin Sisko to change the name of the USS Sao Paulo to USS Defiant. (DS9: "The Dogs of War")

Chiefs of Starfleet Operations Edit

Admiral Bob in 2287, from Star Trek V: The Final Frontier, and Vice Admiral Leyton in 2372, from DS9: "Homefront", could hold this position, but it was never confirmed on screen. In the Star Trek Encyclopedia (4th ed., vol. 1, p. 463), Leyton was said to have filled this position in the 2370s.
Admirals Richard James, Rick Berman, Brad Yacobian, and Vice Admiral Adele Simmons were high-ranking members of Starfleet Operations and may have held this position as well.
