Technology & Combat Characteristics
The Duel Gundam is the earliest unit to be developed in the Earth Alliance's G Project series of prototype MS. It is designed to be a general-purpose machine that has well-balanced performance, and also serves as a development base for the other MS in the project.
The armament of the Duel is rather simple and consists of two head-mounted "Igelstellung" 75mm multi-barrel CIWS guns, which would later become standard weaponry on most suits to shoot down incoming missiles and close enemy units. For close combat, the suit features two beam sabers, which are stored on the backpack and hand carried when in use. For ranged combat, the Duel uses a 57mm high-energy beam rifle with an attached 175mm grenade launcher. For defense, the suit mounts a single physical shield. Duel also has a rail bazooka as optional weapon, but it was taken and used by MBF-P01 Astray Gold Frame to escape from Heliopolis. As with the other suits developed under the G Project, the Duel was equipped with the new Phase Shift armor, making it nearly impervious to shell firing weapons.
After being stolen by ZAFT and damaged in battle, the suit is upgraded with the Assault Shroud armor, which is based on similar equipment used by GINN and CGUE. The Assault Shroud is a set of ejectable equipment mounted around the Duel’s body to enhance overall combat performance. It adds a "Shiva" 115mm railgun to the right shoulder and a 220mm 5-barrel missile pod to the left shoulder for additional firepower. Although the equipment worked well in space, it performs poorly under gravity due to its bulk.
