An operations officer on the bridge of the alternate-reality Enterprise, who tries to raise the fleet at Vulcan in the 2009 film Star Trek and reappears in Star Trek Into Darkness.
Hannity serves on the bridge of the USS Enterprise in the alternate reality, played by Amanda Foreman.
In the 2009 film Star Trek, Kirk bursts onto the bridge warning that the ship is flying into a Romulan trap. Captain Pike orders Hannity to hail the USS Truman; she reports that the rest of the fleet has reached Vulcan but that all contact with it has been lost, which persuades Pike to raise shields before dropping out of warp.
Foreman returns in Star Trek Into Darkness, set in 2259, where her character tells acting captain Sulu that the signal from the trading ship carrying Kirk, Spock and Uhura to Qo'noS has been cut off. In that film's credits she is listed as Ensign Brackett.
