VIII. Armor

The armor on the RGM-84 is a low-mass lunarium titanium composite plating that is the standard for command mobile suits known as Gundarium. Aside from the superb protection provided against projectiles, missiles, and other kinetic weapons, this armor is also fairly resistant to plasma globes (annihilation discs), lasers, and to a lesser extent, particle guns too, owing to the fact that the armor can flake off and evaporate in layers under fire from such high-energy weapons, taking much of the weapon's energy and converting it into the latent heat of sublimation in the armor. The armor stops all small arms fire, and has good resistance to all weapons commonly mounted on combat mecha. This new armor is also much lighter than most armors weighing a full two thirds less than the traditional armor's mounted on mecha but is almost twice as expensive to make.

The Zeta Gundam provides full protection from nuclear, biological, and chemical hazards, using an overpressure cockpit environment activated by radiation and hazardous chemical sensors, or manually when biological warfare conditions are anticipated. The internal consumables supplies can provide atmosphere for three days maximum.

IX. Development

Following the development of the RGX-78 Gundam Mark II and its moveable frame design, Anaheim sought to develop a practical movable frame mobile suit to replace the RGM-78NT-01 as the RDF's platoon leader mobile suit design.  Thanks to much of the data gathered by the Gundam Mark II, design of the Zeta proved easier than previous designs and went ahead quiet quickly  thanks in part to is design team lead by LTJG Camille Bidan, a 17 year old mobile suit ace and engineering genius came up with the RGM-84 Zeta Gundam together with LT Astonage Medosso, a mobile suit mechanic.  The design was a radical departure from the original Gundam and Gundam Alex designs.  The Zeta looked much different, much more streamlined than the blocky RGM-78 series.  Along with the movable frame, several new technologies were employed to assist in increasing the balance and agility of the mobile suit.  A pair of wing binders as they became known were added to the back of the suit as well as a tail binder which carried an additional thruster and acted as additional limb for balancing.  

The RGM-84's armament was also different than its predecessors.  In addition to the standard tachyon rifle and beam saber which were upgraded, it also featured an internal missile launcher on each wrist which gave it additional short range combat option other than its rifle.  An very powerful optional weapon was developed for use with the Zeta giving it standoff defensive and offensive abilities.  The ML-03 tachyon cannon is basically an miniature version of a warship class tachyon cannon.  It gives Zeta the ability to destroy an entire group of closely packed mecha in one shot not to mention threaten even large capital ships. The Zeta was also a leap forward in agility from the previous generation thanks to both the magnetic coating and the new wing and tail binders.  These new systems when combined with the new thruster layout gave the Zeta increased combat endurance in case of engine failure and improved efficiency in and out of an atmosphere.

First rolled out in mid 2054 at the Anaheim Electronics testing facility on Luna, the Zeta Gundam quickly underwent testing and impressed the military so much that immediate production and ordered enough to replace the RGM-78NT-01 currently in service.  The Zeta Gundam first entered service in 2055 and quickly proved itself to be as advertised, much faster and more agile than the Gundam Alex not to mention a more varied weapons suite.  In 2057 Anaheim produced the RGM-84C Zeta Plus.  This mobile suit featured more powerful engines and an additional pair of small tachyon cannons mounted on the hips of the mobile suit to boost the medium combat capabilities and battlefield endurance of the Zeta Plus.  In the spirit of the previous series of FAWS as seen on the RGM-78 series Anaheim also developed an armor and weapons package for the RGM-84.  Dubbed the GBP-07 the system adds additional armor plating at key points across the mobile suit along with extra weapons.  The system carries an additional fifty MPM-23 Dagger missiles for a total of 72 missiles.  In addition the system is designed to carry the ML-03 easily on the back making the Full Armor Zeta Gundam among the most heavily armed mecha in the known galaxy. 

The RGM-84 series first saw major conflict in the Transient War in 2057 and quickly distinguished itself against all types of mecha especially the Male Power Armor and the fearsome Female Power Armor.  The Zeta Gundam continued to see wide service for the next several use and saw service in the beginning of the 4th Robotech War and was finally fully retired in late 2065 when it was replaced by the RGM-90 Double Zeta Gundam.
