The RGM-89R Jegan A-Type is a mobile suit from the Mobile Suit Gundam F91 movie.

Technology & Combat Characteristics

The RGM-89R Jegan A-Type is an upgraded version, and one of several subtypes, of the RGM-89 Jegan. Of all of the Jegan's descendants the A-Type features the greatest improvement in speed and maneuverability by its possession of several additional rocket thrusters and vernier thrusters. Also, sections of the armor have been removed to give it a slight decrease in the mobile suit's empty weight. Finally the A-Type features the most powerful nuclear fusion reactor of any other member of the Jegan line.

A noticeable feature about the Jegan A-Type is its modified set of armaments from the original or other subtypes of the Jegan. The main difference is the removal of the hip-mounted grenade rack and its replacement with a second beam saber recharge rack. To compensate for the removed grenades the Jegan A-Type's left forearm is equipped with a 2-tube grenade launcher, not unlike what was found on the MSZ-006 Zeta Gundam and its descendants.


  • Vulcan Gun Pod
The vulcan gun pod is an optional close-range defensive armaments mounted on the head that is based on the technology of the RX-178 Gundam Mk-II. The vulcan guns are shell firing weapons with a high-rate of fire but have little power and are generally ineffective against mobile suits, though they can damage lightly armored areas such as the sensors. The vulcan guns are ideal for shooting down small, fast moving, lightly armored targets such as missiles or small vehicles.
  • 2-tube Grenade Launcher
The A-Type Jegan mounts a 2-tube grenade launcher on its left arm. While grenade launchers used during the One Year War fired unguided grenades, later versions launch self-propelled homing missiles with their own optical guidance systems.
  • Beam Saber
The standard close range armament for most Federation mobile suits. The beam saber is a small cylindrical device held in the mobile suit's hands when operated and is powered by an energy capacitor that is recharged from special racks. The beam saber emits a blade of plasma contained by an I-Field and is capable of cutting through almost any metal that has not been treated with anti-beam coating. The A-Type Jegan is equipped with two beam sabers that are stored in hip mounted recharge racks, one on each hip.
  • Shield
Shields are simple in their design, being essentially thick slabs of metal that the equipped mobile suit can use to absorb the impact from attacks that, for whatever reason, cannot be dodged. However shields can only withstand so much pressure before becoming damaged themselves. As technology progressed it became necessary for shields to be treated with an anti-beam coating as a measure of defense against beam weapons which can normally penetrate any physical barrier, however the coating gets gradually burned away each time a beam strikes it until it is rendered useless. The A-Type Jegan's shield can be mounted onto either arm and mounts additional weapons in the form of a pair of 4-tube missile launchers.
Despite the general effectiveness standard shields have proved to be ever since mobile suits were first developed, the models employed by the Federation in the UC 0120s proved unable to withstand the electromagnetically accelerated spear fired from the shot lancer used by the Crossbone Vanguard mobile suits.
  • 4-tube Missile Launcher
The standard shield of the A-Type Jegan mounts two 4-tube missile launchers that fires rocket propelled low-yield explosives designed to destroy mobile suits.
  • Beam Rifle
A standard hand carried ranged beam weapon is the beam rifle. Capable of firing concentrated mega particles, attacks from a beam rifle are can damage any ordinary armor that has not be specially treated to resist it. One of the more effective methods of blocking a beam rifle is to use a beam shield. When the technology became available it became standard for beam rifles to be powered by a replaceable e-pac that could be replaced mid-battle if they ran out of power.


Introduced in the early UC 0090's the base form of the RGM-89 Jegan would be upgraded over the three decades of its service life, producing several subtypes. Of the three subtypes that existed during the year 0123 UC the A-Type was the fastest and most maneuverable, making it a favorite for squadron commanders. However by that year even the A-Type, arguably the Jegan with the best performance rating, was horribly out-of-date as the Federation had already developed and put into mass production two newer, smaller, more efficient models of mobile suits that had superior performance ratings to any Jegan model mobile suit.

Despite the new mobile suits the Earth Federation seemed to be oblivious to its need to replace the aging Jegan line of mobile suits until the invasion of the Crossbone Vanguard, whose newer and more efficient mobile suits handily defeated any Jegan they battled against.
