RMS-179 (RGM-79R) GM II

The RMS-179 (RGM-79R) GM II was a mass production general purpose mobile suit developed by the Earth Federation. It used the designation RGM-79R for units upgraded from the RGM-79 GM, and RMS-179 for newly constructed units. The “RGM” in the model code indicated that it was a general purpose, multi-role mobile suit. The “R” in the model code indicated it was an upgraded version of the GM. The “RMS” in the model code stood for remake mobile suit.

History

After the One Year War, the Earth Federation begun upgrading the RGM-79 GM with newer technology. After existing GM units had been upgraded into the RGM-79R GM II, the Federation started constructing new units of the GM II design under the designation RMS-179 GM II.

The Federation started deploying the GM II in UC 0084 as the mainstay of its mobile suit lineup. The GM II was often deployed during the Gryps Conflict in UC 0087 before the RGM-86R GM III succeeded it. Despite this, the GM II continued to serve the Federation and saw action in UC 0096 when Zeon Remnants attacked the Federation’s capital Dakar and Australia’s Torrington Base.

Anaheim Electronicsdeveloped the GM II into the MSA-003 Nemo and the latter served as the mainstay of the AEUG mobile suits.

There are two known variants of the GM II, the RMS-179 GM II Semi-Striker and the RS-82B-R GM II Custom.

Design

The rapid advancement of mobile suit technology meant that the Earth Federation had to upgrade its RGM-79 GM units to keep up. Units designated RGM-79R GM II were upgraded GM frames, while those designated RMS-179 GM II were newly constructed.

The GM II used a high output-generator, had improved thrusters for greater propulsion, amplified actuators for faster limb response, and additional verniers for increased manoeuvrability.

Compared to the GM, the GM II had a more powerful ultracompact fusion reactor that generated 1,518 kW to provide greater propulsion.

Four rocket thrusters with a combined output of 62,000 kg provided main propulsion for the GM II. Its main set of four thrusters had an output of 15,500 kg each, while ten vernier thrusters and apogee motors allowed fine control.

The GM II was built with titanium ceramic composite. It had the new standard panoramic cockpit with linear seat in its torso.

It had a set of standard sensors with unrated detection range.

Armaments

The GM II’s standard weapons were a beam sabre for melee combat and an optional handheld rifle for ranged attack. It could also equip other handheld weapons used by the RGM-79 GM.

60 mm vulcan guns

A pair of fire-linked 60 mm gatling vulcan guns were mounted on either sides of the GM II’s head.

Each vulcan gun was loaded with 600 rounds of ammunition and fired at a rate of 1,600 rounds per minute. It was used primarily against light-armoured support units. Sustained fire from the guns could damage mobile suits and were often used in close distance combat.

Beam sabre

The GM II had a beam sabre for close combat.

The beam sabre used an I-field to contain Minovsky particles within the shape of a blade. The beam sabre could cut through almost any material. Minovsky particles were channelled into the sabres through an energy capacitor (E-cap) attached to their hilts. The E-cap recharged with Minvosky particles from the GM II’s reactor when the sabre was stored in the recharge rack in the rear waist armour of the mobile suit.

Beam rifle

The GM II could carry a BOWA·BR-S-85-C2 beam rifle for ranged attack. It was designed along with the BOWA BR-S-85-L3 sniper beam rifle used by the RGC-80 GM Cannon.

The beam rifle drew its rounds from energy capacitors (E-caps), clips of charged Minovsky particles. Minovksy particles broke down matter at a molecular level, allowing the beam rifle bolts to penetrate even the thickest armour. This meant that a single shot could destroy a mobile suit.

90 mm rifle

The HFW-GR·MR82-90 mm GM rifle was the GM’s main handheld weapon that the GM II could also equip. Compared to the HWF GMG·MG79-90 mm machine gun, it had a 15% increase in muzzle velocity due to its extended barrel, thus giving it greater armour piercing ability. It was clip-fed using clips with 30 rounds each. Two spare clips were stored in the shield.

The rifle could attach a beam bayonet or grenade launcher under the barrel. It could also mount a longer barrel, scope and stock.

90 mm machine gun

The HFW-GMG·MG79-90mm bullpup machine gun was a ranged weapon designed for the GM that the GM II could also use. It was developed for use in both space and ground. Its small size deceives its firepower. It could easily take out mobile suits while maintaining accuracy. The machine gun also had a sensor system with visual and laser sensors to the enhance target acquisition capability of the GM II targeting system.

100 mm machine gun

The YHI YF-MG100 100 mm machine gun was a ranged weapon designed for the GM that the GM II could also use. However, it was used less often after the Federation switched to 90 mm calibre guns.

It had a box magazine and folding stock, giving it an excellent rate of fire and steady grip. It used a smoothbore barrel that lacked rifling and had to be replaced every 3,000 rounds. It could fire High Explosive Anti-Tank (HEAT) rounds, Armour-Piercing Fin-Stabilised Discarding-Sabot (APFSDS) rounds, and High Explosive Squash Head (HESH) rounds.

380 mm hyper bazooka

The GM II could equip the BLASH XHB-L-03/N-STD 380 mm hyper bazooka designed for the RX-78-2 Gundam in situations that required heavy fire power. The bazooka was stored on a rack behind right shoulder when it was not in use.

Designed to fire adhesive rounds to immobilise enemies, the bazooka could also load other types of ammunitions such as explosive rounds or pellet shot rounds.

Shield

The GM II could optionally equip an RGM-M-Sh-007 shield for defence. The shield was made of titanium ceramic composite and was an upgraded model of the luna titanium RGM-M-Sh-003 shield. It was mounted on either forearm.

The shield was able to block most ballistic and explosive projectiles. It was also effective in melee combat.
