The MS-15PLUS Gann Ex is a mobile suit that appeared in the Jupiter (Zeus) in Operation Titan U.C. 0083 manga..

Technology & Combat Characteristics

An improvement over the original YMS-15 Gyan, the Gann Ex features enhancements in communication capabilities and its generator that allow operation in the Jupiter sphere. It also lacks the Gyan's trademark Beam Saber.


  • Beam Rifle
The beam rifle, as its name suggests, is a high-powered energy beam weapon that fires condensed mega particles which can penetrate almost any armor that has not been treated with specific counter-measures.
  • Shield
The Gann EX is equipped with a large circular shield that not only defend it from beam weapons, but also has offensive capabilities in the form of missiles and hide bombs stored within.
  • Shield Missile
The shield of the Gann Ex stores many small missiles. Though individually not very powerful these missiles are deadly when fired in massed volleys. Additionally these were not meant for long range combat, instead serving more as a mid to close range ranged weapon.
  • Hide Bomb
A type of space mine (space version of the naval mine). The hide bombs freely floats around in space once deployed, damaging any Mobile Suit that come near them


The Gann Ex was used by Char Aznable to defend a Zeon resource base from an attack by the Earth Federation Forces.
