The unnamed commanding officer of the USS Saratoga in Star Trek IV: The Voyage Home, whose ship is the first Starfleet vessel crippled by the whale probe on its way to Earth.
The captain of the USS Saratoga appears early in Star Trek IV: The Voyage Home. Her ship is on patrol near the Neutral Zone when it detects a huge cylindrical probe on course for the Terran system.
As the probe passes, its transmission drains every system on board. The captain reports to Starfleet Command that the Saratoga is drifting on reserve power and asks for instructions, giving Earth its first warning of what is coming. She is seen again on Admiral Cartwright's screens, her crew still struggling to survive.
The role was played by Madge Sinclair, and is often cited as the first woman shown commanding a Federation starship. Sinclair later played Captain Silva La Forge in The Next Generation.
