The FXA-05D G-Defenser is a Mobile Suit support craft, it is featured in the Mobile Suit Zeta Gundam series.

Technology & Combat Characteristics

The FXA-05D G-Defenser is a fighter craft created to support the RX-178 Gundam Mk-II in battle. On its own, the G-Defenser's combat abilities are similar to FF-X7-Bst Core Booster from the One Year War in that it is a space fighter with multiple missiles, vulcan guns, and beam weapons. Although it was armored with Gundarium alloy, it relies more on its speed to avoid attacks.

When fighting with the RX-178 Gundam Mk-II, the G-Defenser docks with the Gundam Mk-II. During the docking sequence, the cockpit capsule of the G-Defenser disconnects from the main body and operates independently, similar to the FF-X7 Core Fighter. When docked, the G-Defenser's 14-tube missile pods, the long beam rifle, and the vulcan guns stay with the Gundam, leaving the cockpit capsule with only the laser guns.

Later, the G-Defenser is also used by RGM-86R GM III as the mobile suit has the same model of backpack as the Gundam Mk-II.


  • 14-tube Missile Pod
The FXA-05D G-Defenser mounts a pair of 14-tube missile pods that are mounted in the binders on the main body.
  • Long Beam Rifle
The most powerful weapon of the FXA-05D G-Defenser is the long beam rifle, a high powered energy weapon mounted on the starboard side of the main body. Although the G-Defenser and its weapons are powered by a Minovsky type ultracompact fusion reactor, its small size limits its power output, limiting the G-Defenser's ability to use the long beam rifle when not docked with the Gundam Mk-II.
  • Mini Laser Gun
The FXA-05D G-Defenser mounts a pair of mini laser guns on the nose of the cockpit capsule. These mini laser guns are the cockpit capsule's primary and only weapon when disengaged from the main body. Because of the development of semi-transparent coating before the One Year War laser weaponry are limited in effectiveness, especially against battleships. The mini laser guns are fire-linked and have a power rating of 1.7 MW each.
  • Vulcan Gun
A common defensive weapon used in close to mid range combat. While it can normally do little damage against the armor of a mobile suit it serves as a much more efficient and cost-effective as a means to shoot down incoming missiles, as opposed to using the long beam rifle, the power of which would be over kill and is far more limited in use. The FXA-05D G-Defenser mounts four vulcan guns, a pair on each missile pod binder.


With the appearance of the Titans' transformable mobile suits, the RX-178 Gundam Mk-II is in danger of being outclassed. In response, Anaheim Electronics develops a dedicated support fighter which can dock with Gundam Mk-II to form the G-Flyer transport vehicle, and its cockpit capsule then detaches, leaving the armament unit wrapped around Gundam Mk-II. Technically, this combination of Gundam and armament unit is known as the "Mk-II Defenser," but with its powerful engines, movable shields, and devastating long rifle, this powered-up form more than earns its nickname of RX-178+FXA-05D Super Gundam.

Both the G-Defenser and its cockpit capsule were destroyed by RX-139 Hambrabi piloted by Yazan Gable, although the Gundam Mk. II survived the destruction of its other half.
