The RMA-081 G Big Zamm (RMA-081 ジ-ビグ・ザム, Ji - Bigu Zammu^?)is a variant of MA-08 Big Zam that appeared in manga Mobile Suit Gundam 0083 Rebellion.

Technology & Combat Characteristics

The G Big Zamm is a heavily modified MA-08 Big Zam that was destroyed during the Battle of Solomon. Due to its status as a former Principality of Zeon mobile armor, it was heavily modified with additional I-Field generators in the upper hull, four added vulcan guns, and the mono-eye sensor was replaced with a visor-type sensor to fit Earth Federation Forces' standard. Thanks to such modifications, it had better firepower, lighter overall weight, but at the cost of lower generator output.

Armaments

• Large Mega Particle Gun

The primary weapon of the G Big Zamm is a large mega particle gun that sits prominently in the center of the mobile armor's body. This mega particle gun draws a vast amount of energy from the four fusion reactors, allowing it to fire a mega particle beam that can destroy multiple battleships in a single shot. It is the most powerful weapon used by any mobile weapon or battleship, second only to the superweapons employed by both sides.

• Vulcan Guns

A tertiary weapon fitted in the G Big Zamm's main body are two pair of shell-firing vulcan guns, placed to cover a blind spot not protected by the mega particle guns. Though larger than most vulcan guns, the G Big Zam's vulcan guns can still only deliver light damage to the armor of a mobile suit and are better suited for shooting down lightly armored targets such as missiles.

Special Equipment

• I-Field Barrier Generator

When Minovsky particles are released into the air or into open space, the positive and negative particles spontaneously align themselves into a three-dimensional cubic lattice. Due to the repulsive and electrostatic forces between the Minovsky particles, this lattice functions as a kind of a force field, which is referred to as an I-field. This field has difficulty permeating conductive materials like metal, water, and plasma, and it exerts a repulsive force against mega particles. An I-field is used to to deflect enemy mega particle beams. Due to its high power requirements, the I-field generator originally could only be installed in large mobile weapons. When the generator is activated, the I-field forms an invisible barrier around the mobile weapon, protecting it from incoming beam attacks. However, this barrier has no effect against solid objects like missiles and projectiles, and beam weapons can still be used at point blank range within the barrier's boundary.

Notes and Trivia

• According to Masato Natsumoto, he intentionally prepares the G Big Zamm specifically designed for Anavel Gato's return to Solomon, by blending Zeon and Earth Federation design aesthetics to mock the Big Zam as the symbol of Solomon.
