Technical and Historical Notes

Following the testing of the RGC-80-1 GM Cannon Test Type, the Earth Federation Forces quickly followed up with the final RGC-80 GM Cannon, correcting the problems encountered in the test model. Put into production in late UC 0079, the production-model GM Cannon mounted only one rocket-launching 240mm cannon, complemented by heavier armor on the legs to offset the recoil. Being a derivative of the standard RGM-79 GM, the GM Cannon could also carry the same hand weapons and shields as its close-combat sibling. Six units were originally produced, taking part in the Federation's offensive to take back North America. After the recapture of California Base, another 44 units were produced, scattered to all parts of the Earth Sphere as the Federation offensive drove Zeon off of Earth and into its home territory in space.
