Tricobalt satellites were one of the computerized weapons employed by Vendikar during its five hundred year war with Eminiar VII. At the time of the visit by the USS Enterprise in 2267, these weapons existed only in the data stores of the powerful computers that waged the war. Such a weapon "destroyed" the Enterprise while it orbited Eminiar, forcing Anan 7 to demand that Captain Kirk beam his crew down so they could be killed and their deaths recorded in keeping with the treaty that governed the conduct of the war. (TOS: "A Taste of Armageddon")
