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 of 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 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 heavy machine guns on its body
  • 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 without anti-beam coating. 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, and powered by the suit's reactor. The VSBRs can fire either low-speed beams with high destructive power, or high-speed beams with high penetrating power, sufficient to destroy two MS with one shot or pierce a beam shield. The VSBRs typically slide under the shoulder when deployed.
  • 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.
  • Grenade Launcher
Replacing the beam spray gun, a grenade launcher is mounted on the Silhouette Gundam Kai's right forearm.
  • 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.






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