Computer program aboard starships for destruction of the vessel, should the ship be captured or controlled by an enemy. Time until auto destruct is sixty seconds.
On Galaxy-class starships, for example, activation of the program requires verbal orders and handprint verification from the two most senior command officers of the ship.
Auto destruct's most infamous use occured in 2285, when Admiral Kirk destroyed Enterprise in order to prevent her from falling into enemy hands.
