The culmination of development conducted by the Earth Federation Forces' Strategic Naval Research Institute under their "Formula Project" flag, the Gundam F91 is truly a revolutionary design for the next generation of mobile suits. The F91 represents the final goal of SNRI to develop a smaller, lightweight, high-performance mobile suit. Its compact size mounts enough weaponry to put it on par with other general purpose units at the time, and the F91 incorporates many advanced new technologies developed under the Formula Project. One of these technologies is the Variable Speed Beam Rifle, or "VSBR" for short, which has already been successfully tested on the F90V Gundam F90 VSBR Type. Rather than being a hand-carried weapon powered by an energy cap or e-pac, the VSBR is mounted on the mobile suit itself and powered directly by its reactor. The pilot can adjust the speed at which the mega particles used in the beam fire are accelerated. Slower-speed particles produce a wider beam that delivers more raw damage, and higher-speed particles create a more tightly focused, penetrating beam. Thus, the F91's pilot can 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 is the bio-computer system developed by Dr Monica Arno. This system acts as a sort of "reversed" psycommu system, relaying information directly to the pilot's mind rather than vice versa. The bio-computer, however, can be used by normal pilots, and it gives the pilot many advantages by directly providing him with tactical and sensor data, piloting suggestions, and so on. Thus, the bio-computer allows the pilot to react more quickly and decisively to any battle situation, and it also makes 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, is slowly upgraded and modified over the next several years. Its final assembly, which incorporates the bio-computer system, is cut short when the Crossbone Vanguard force begins conquering the Frontier Side area in March UC 0123. The F91's parts are stowed aboard the Federation Forces training ship Space Ark, and during an escape to the Frontier I Colony, the Space Ark crew rescues a group of civilian students who were also fleeing. Since the ship's complement is made up of trainees - and a skeleton crew, at that - a pilot is needed to pilot the F91 when it was completed. Seabook Arno, one of the rescued civilians, is 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 finds himself performing his duties well, adapting to the F91 easily and scoring three enemy MS kills on his first sortie.
The Gundam F91 performs superbly during the conflict, and its abilities soon have another surprise in store for Seabook. Being a very high-performance unit, the F91's weapons and systems generate a tremendous amount of heat. This heat is normally dissipated through a seat of radiator fins built into the mobile suit's shoulders; however, excessive amounts of heat sometimes still remain throughout the mobile suit's body. Another method of getting rid of this heat is by "shedding" the heated outermost layer of the Gundam's armor; this has the rather dramatic effect of creating "after-images" of the mobile suit while it was moving. While confronting Crossbone Vanguard leader Carozzo Ronah's deadly XMA-01 Rafflesia mobile armor, Seabook finds this ability useful in tricking his enemy into attacking targets that are not where they appear to be. Although initially developed as a prototype unit, the F91's performance during the Crossbone Vanguard conflict later results in this Gundam being put into limited mass production. Some of these mass-produced F91s are used by the Federation Forces in a war against the Jupiter Empire in UC 0133.
