Earth Federation RGM-109 Heavygun Head height: 15.8 meters Base weight: 9.5 tons Full weight: 23.5 tons Generator: 2870 kW Thrusters: 82,260 kg Apogee motors: 59 Armor materials: Gundarium alloy Armament: vulcan gun x 2 quadruple grenade rack x 2 beam saber beam rifle Pilot: Birgit Pirjo By the second century of the U.C. calendar, the conflicts and rebellions of previous years appeared to have subsided, and the Earth Federation decided to develop a new line of miniaturized mobile suits in order to reduce military expenses. The Heavygun, the first mass production model derived from this program, was produced by the civilian company Anaheim Electronics as a proof of concept. Although it uses the same type of generator as the Jegan series, its smaller size gives the Heavygun greater mobility and maneuverability. Nonetheless, this early model is outclassed by the newer F71 G-Cannon and the mobile suits of the Crossbone Vanguard.
