The Earth Defense Directorate (EDD for short), was founded by The United Nations as part of the United Earth Agreement, which established The United Nations as the true governing power of Earth. The EDD represents the merging together of the various national militaries of Earth, with its primary focus being on the Defense of Earth and Terran Space.
To meet this end, the EDD fields a fleet of almost 20 Daedalus Class Vessels, all equipped with Asgard Weapons and systems. In addition to the Fleet, the EDD maintains a vast array of service facilities, Bases, F-302 Fighters, throughout the Sol System.
In addition to this, Stargate Command now answers to the EDD, maintaining Earth’s security through continued exploration of the Stargate Network which brought so many technological blessings to Earth. And finally, the old IASA Programs have been folded into the EDD, adding to the technological progress that has occurred on earth in the past several years.
