Full Armor Gundam As the RX-78-2 Gundam continued to perform beyond all expectations during the last months of the One Year War, a program was initiated by the Earth Federation Forces to develop and investigate options for possible upgrades to the Gundam. Called "FSWS" (Full Strike Weapon System), Federal engineers developed several options under this program that would involve adding external systems to boost the Gundam's performance in different areas. One such design concept was the FA-78-1 Gundam Full Armor Type, which featured a tremendous amount of firepower for a single mobile suit. In addition to removable external armor modules all over the Gundam's body, new weapons would be added, including a shell-firing cannon, several missile launchers, and a large, hand-held 2-barrel beam gun. Despite the extra thrusters to be mounted in the external armor, however, all the extra weight would have created an unacceptable loss of speed and performance. In the end, the FA-78-1 Gundam Full Armor type never saw construction, and its concepts would serve as the basis for the much-improved FA-78-2 Heavy Gundam.
