The RXF-91A Silhouette Gundam Kai is a mobile suit that appears in the manga/model kit series Mobile Suit Gundam Silhouette Formula 91 in UC 0123.

Technology & Combat Characteristics

After Tokio Randall and his RXF-91 Silhouette Gundam broke through the Crossbone Vanguard's siege in the Zebra Zone, the Silhouette Gundam's wreckage was returned to Anaheim Electronics and subsequently refurbished as the RXF-91A Silhouette Gundam Kai. It featured reinforced armor throughout the chest, cockpit hatch, and near the intakes. Additionally, it has improved main generator output and is retrofitted with a new model VSBR.


  • Vulcan Gun
The Silhouette Gundam Kai is equipped with a pair of head mounted Vulcan guns to serve as a mid-close range defensive weapon. While they do little damage against the armor of a mobile suit, they are useful for shoot down incoming missiles, small attack vehicles, or to deter closing in enemy machines.
  • Mega Machine Cannon
The Silhouette Gundam Kai is equipped with a pair of fire-linked mega machine cannons in its upper chest, and they are more powerful than the vulcan guns.
  • Heavy Machine Gun
In addition to the mega machine cannons mounted in the chest, the Silhouette Gundam Kai is also equipped with a pair of fire-linked heavy machine guns mounted in the unit's right forearm.
  • Beam Saber
The standard close-combat melee weapon of most MS, beam sabers are powerful weapons that emit a blade of plasma contained by an I-field that can cut through any physical armor. The Silhouette Gundam Kai is equipped with two beam sabers stored on the backpack.
  • VSBR
The most powerful weapon of the Silhouette Gundam Kai Type is a pair of Variable Speed Beam Rifle (abbr. VSBR) on its backpack. 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 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 create a more tightly focused, penetrating beam. Thus, the Gundam'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.
  • Beam Shield
Mounted on the left forearm of the Silhouette Gundam Kai is a beam shield generator. Unlike an I-field generator, which is effective only against beam attacks, the beam shield can block both beam and projectile weapons.
  • Beam Rifle
The beam rifle is the standard ranged weapon of many mobile suits, it fires a compressed mega particle beam which can penetrate any physical armor, leading to the saying that any mobile suit equipped with a beam rifle had the power of a battleship at its disposal. The Silhouette Gundam Kai's beam rifle is powered by a rechargeable E-cap and can be stored on the waist weapons mount.
  • Grenade Launcher
The beam rifle is fitted with an underslung single-shot grenade launcher, which can be loaded with a variety of grenades. The grenade fired is not very effective against large ships, but is an ideal mid-range anti-mobile suit weapon.




  • The "A" in the "RXF-91A" designation stands for "ADVANCED".
  • "Kai" is the Japanese Kanji character "改", in English meaning "modified".
