The MSA-004 Nemo II was a prototype assault mobile suit developed by Anaheim Electronics for the Anti-Earth Union Group (AEUG).

“MS” in the type code indicated that it was a mobile suit and “A” meant it was an Anaheim design. The “004” code number meant it was the fourth design in the line.

History

During the Gryps Conflict, the Anti-Earth Union Group deployed many RMS-179 GM II at its frontlines. However, its leadership wanted their own mass-produced mobile suit that rivalled and surpassed the GM II used by the Titans and Earth Federation. The AEUG engaged Anaheim Electronics to design the new unit.

After rejecting the first two concepts, AEUG approved the third design, the MSA-003 Nemo. The Nemo remained in service through the Gryps Conflict and the First Neo Zeon War.

The AEUG wanted a successor to the Nemo as its mainstay mobile suit to keep up with the newer suits that the Titans were deploying. The MSA-004 Nemo II was developed as the prototype for the next generation of the Nemo line. The Nemo II was not adopted by the AEUG for mass production due to undisclosed reasons. The design was further developed into the MSA-004K Nemo III prototype that was also not mass-produced.

Design

The MSA-004 Nemo II featured an upgraded reactor that provided greater power output compared to the MSA-003 Nemo. While it had lower propulsion with combined thruster output at 68,600 kg compared to the 91,600 kg of the Nemo, it achieved greater mobility through more advanced verniers and apogee motors.

The mobile suit had a standard panoramic cockpit with linear seat in its torso.

Armaments

The Nemo II’s standard weapons were a beam saber for melee combat and a beam rifle for ranged attacks.

60 mm vulcan guns

A pair of fire-linked 60 mm gatling vulcan guns were mounted on either sides of the Nemo II’s head. These were similar to the ones used by the RX-78-2 Gundam.

Each vulcan gun was loaded with 400 rounds of ammunition and fired at a rate of 1,600 rounds per minute. It was used primarily against light-armored support units. Sustained fire from the guns could damage mobile suits and were often used in close distance combat.

Beam saber

The Nemo II carried a beam saber stored in its rear waist armor. It had output rated at 0.4 megawatts. These beam sabers were designed for the RMS-099 Rick Dias, but the Nemo was designed to be compatible with them.

The beam saber used an I-field to contain Minovsky particles within the shape of a blade. Minovsky particles broke down matter at a molecular level. This meant that the beam saber could cut through almost any material.

Minovsky particles were channelled into the saber through an energy capacitor (E-cap) attached to its hilt. The E-cap recharged with Minvosky particles from the Nemo II’s reactor when the saber was stored in the recharge rack.

Beam rifle

The Nemo II could optionally carry a BOWA·BR-S-85-C2 beam rifle. The rifle was made to conform with AEUG standards, allowing it to be used across different models and generations of AEUG mobile suits.

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 armor. This meant that a single shot could destroy a mobile suit.

Shield

The Nemo II used the same shield as the MSA-003 Nemo. The shield could switch between an expanded state and a collapsed state. Its surface had an anti-beam coating to defend against beam attacks. The shield also had sharp edges at the top for ramming attacks and latches on the back for mounting other weapons or equipment.
