The culmination of development conducted by the Earth Federation Forces’ Strategic Naval Research Institute under their Formula Project flag, the Gundam F91 was truly a revolutionary design for the next generation of mobile suits. The F91 represented the final goal of SNRI to develop a smaller, lightweight, high performance mobile suit. Its compact size mounted enough weaponry to put it on par with other general purpose units at the time, and the F91 incorporated many advanced new technologies developed under the Formula Project. One of these technologies was the Variable Speed Beam Rifle, or VSBR for short, which had already been successfully tested on the F90V Gundam F90 V-Type. Rather than being a hand-carried weapon powered by an energy cap or e-pac, the VSBR was mounted on the mobile suit itself and powered directly by its reactor. The pilot could adjust the speed at which the mega particles used in the beam fire were accelerated. Slower speed particles produced a wider beam that delivered more raw damage, and higher speed particles created a more tightly focused, penetrating beam. Thus, the F91’s pilot could choose to deliver beam damage on a wider area or focused, high speed shots to penetrate thick armor or even beam shields. Another new technology incorporated in the Gundam F91 was the bio-computer system developed by Dr. Monica Arno. This system acted as a sort of “reversed” psycommu system, relaying information directly to the pilot’s mind rather than vice versa. The bio-computer, however, could be used by normal pilots, and it gave the pilot many advantages by directly providing them with tactical and sensor data, piloting suggestions, and so on. Thus, the bio-computer allowed the pilot to react more quickly and decisively to any battle situation, and it also made a novice pilot’s job easier in terms of adapting to the new mobile suit.
The F91 prototype, originally manufactured by SNRI in UC 0116, was slowly upgraded and modified over the next several years. Its final assembly, which incorporated the bio-computer system, was cut short when the Crossbone Vanguard force began conquering the Frontier Side area in March UC 0123. The F91’s parts were stowed aboard the EFF training ship Space Ark, and during an escape to the Frontier I Colony, the Space Ark crew rescued a group of civilian students who were also fleeing. Since the ship’s complement was made up of trainees – and a skeleton crew, at that – a pilot was needed for the F91 when it was completed. Seabook Arno, one of the rescued civilians, was selected for the job, based on his rather shaky credentials of being an engineering student and the son of bio-computer engineer Dr. Arno. Although reluctant to become a soldier, Seabook soon found himself performing his duties well, adapting to the F91 easily and scoring three enemy MS kills on his first sortie.
The Gundam F91 performed superbly during the conflict, and its abilities soon had another surprise in store for Seabook. Being a high performance unit, the F91’s weapons and systems generated a tremendous amount of heat. This heat was normally dissipated through a seat of radiator fins built into the mobile suit’s shoulders; however, excessive amounts of heat sometimes still remained throughout the mobile suit’s body. Another method of getting rid of this heat was by “shedding” the heated outermost layer of the Gundam’s armor; this had the rather dramatic effect of creating after images of the mobile suit while it was moving. While confronting Crossbone Vanguard leader Korozo Ronah’s deadly XMA-01 Lafressia mobile armor, Seabook found this ability useful in tricking his enemy into attacking targets that were not where they appeared to be. Although initially developed as a prototype unit, the F91’s performance during the Crossbone Vanguard conflict later resulted in this Gundam being put into limited mass production. Some of these mass produced F91s were used by the EFF in a war against the Jupiter Empire in UC 0133.
