RGM-79N GM Custom

The RGM-79N GM Custom was a limited production general purpose mobile suit developed by the Earth Federation Forces as part of its military reconstruction project in UC 0081.

The variant code “N” in the model code indicated that it was a variation of the RGM-79 GM.

History

After the One Year War, the Earth Federation Forces began rebuilding its decimated military forces. The Federation’s Augusta Base development team created the GM Custom as a high-performance upgrade of the RGM-79C GM Type C, incorporating data and designs from the RX-78NT-1 Gundam NT-1.

In late UC 0083, three GM Custom units were assigned to the Albion during Operation Stardust. These units saw action against Zeon remnants, with one unit piloted by Lieutenant South Burning being destroyed in combat.

After the Delaz Conflict, the Federation merged the Augusta Base team with its elite Titans unit. The Titans later improved upon the GM Custom’s design to develop the mass-production RGM-79Q GM Quel.

During the Gryps Conflict in UC 0087, the Anti-Earth Union Group deployed several GM Custom units against both Titans and Axis Zeon forces.

Design

The GM Custom featured several significant improvements over the base GM Type C. Its ultracompact fusion reactor output was increased to 1,420 kW to provide greater propulsion and power beam weapons. The mobile suit’s frame incorporated magnetic coating on its joints to increase response speed and reduce friction resistance.

For propulsion, the GM Custom used six rocket thrusters with a combined output of 67,480 kg. The main set of two thrusters each produced 30,000 kg of thrust, while the secondary set of four thrusters each generated 1,870 kg. This represented a substantial increase over the GM Type C’s four main thrusters rated at 12,500 kg each.

The mobile suit had a standard cockpit mounted in its torso and was protected by titanium ceramic composite armor. Its sensor suite was standard Federation equipment with an unspecified detection range.

Armaments

The GM Custom’s standard weapons were 60 mm vulcan guns and a beam saber, supplemented by optional handheld weapons and a shield.

60 mm vulcan guns

A pair of fire-linked 60 mm gatling vulcan guns were mounted in the GM Custom’s head. Each gun carried 600 rounds of ammunition and had a firing rate of 1,600 rounds per minute. While ineffective against mobile suit armor, they excelled at intercepting missiles and engaging lightly-armored targets.

Beam saber

The XB-G-1019H beam saber served as the GM Custom’s primary melee weapon, with an output rated at 0.38 megawatts. When not in use, it was stored in a recharge rack in the backpack. The saber used an I-field to contain Minovsky particles in the shape of a blade that could cut through most materials.

90 mm GM rifle

The HFW-GR·MR82 90 mm GM rifle was the unit’s standard ranged weapon. Its extended barrel provided 15% greater muzzle velocity compared to the standard machine gun, improving armor penetration. The rifle was fed from 30-round magazines, with two spare magazines stored in the shield. It could be equipped with various attachments including a beam bayonet, underbarrel grenade launcher, or sniper configuration with extended barrel and scope.

90 mm bullpup machine gun

The HFW-GMG·MG79 90 mm bullpup machine gun offered an alternative ranged weapon optimized for both space and ground combat. Despite its compact size, it maintained good accuracy and anti-mobile suit capability. It featured an integrated sensor package with visual and laser systems to enhance targeting.

Shield

The RGM·M-Sh-ABT/S-00057 shield was an improved version of the RGM-79G GM Command shield. Mountable on either forearm, it provided protection against both ballistic and explosive weapons while remaining effective in melee combat.
