Built by the Martian colonists, the Delta Astray is also known as Mars's first mobile suit. It utilizes technology from Deep Space Survey and Development Organization and is developed with help from Junk Guild's Lowe Guele, who also gives the MS its name. It is assigned as the personal suit of Martian Coordinator Ergnes Brahe, who commands the interplanetary ship Acidalium. The Δ Astray has a simple armament of a beam rifle for ranged combat and a physical sword for close combat. Since Mars is not involved in the conflict between the Earth Alliance and ZAFT, there are no Neutron Jammers present there, allowing the Δ Astray to be powered by a nuclear reactor. However, when the ship visits the Earth Sphere in late C.E. 73, the Acidalium's crew has to install a Neutron Jammer Canceller on the suit.
