Technology & Combat Characteristics
Based on the Earth Federation Forces's RMS-179 GM II, the MSA-003 Nemo is a mass-production general-purpose mobile suit developed by Anaheim Electronics for the AEUG. As Anaheim Electronics had bought over Zeonic Corps that worked for the Principality of Zeon, its mobile suit technology has Zeon influences and as a result, the Nemo has a mixture of both Zeonic and Federation technologies.
Like most other mobile suits created during the Gryps War, the Nemo has an internal movable frame. Its movable frame is of a new design and reflects the data gained by Anaheim Electronics from the development of the RMS-099 Rick Dias and the MSN-00100 Hyaku Shiki. Thanks to this movable frame, the Nemo has high versatility and can operate in various environments such as zero-gravity, tropical regions, and cold climates. In addition, its legs' movable frame enables high mobility regardless of the environment, and as a result of considering Earth descent operations, it has a highly flexible structure with excellent drop and impact resistance. The Nemo's thrusters layout is designed using the RGM-79SP GM Sniper II's as a reference and this is due to part of the Nemo's development staff having worked on the latter during the One Year War.
Compared to the GM II's titanium alloy ceramic composite, the Nemo has a more durable Gundarium alloy armor. As this armor is produced using the same technology as the RMS-108 Marasai's (another Anaheim Electronics' mobile suit, but provided to the Titans), it has high cost-effectiveness. Most of the Nemo's armaments are the same as those used by existing MS, and it could also use other armaments made by the Federation or Zeon. The Nemo was also relatively easy to pilot even for less skilled recruits, and overall, it was an excellent machine with performance superior to the GM II and RMS-106 Hizack.
History
During the Gryps War in UC 0087, the AEUG initially relied heavily on mobile suits stolen from or brought by defecting members of the Earth Federation Forces, mainly the RMS-179 GM II. However, its leadership soon decided the organization needed a mass-produced unit of their own to compete with the Titans's mobile suits and show that they were a serious threat. The task to develop this new mobile suit went to Anaheim Electronics, resulting in the creation of the Nemo.
The Nemo proved to be both a capable and versatile mobile suit, and served for the entirety of the war. The Nemo was used in various important missions, such as the attack to capture Earth Federation's Salamis Kai-class cruiser, and the orbital drop to attack the Titans' base at Jaburo. As an act of comradeship in their combined goal, the AEUG gave a number of their Nemos to Karaba. The Nemo's design was later used to developed the MSA-004 Nemo II, and also inspired another of Anaheim Electronics' mass production mobile suit, the MSA-007 Nero.
With AEUG and Karaba absorbed into the Earth Federation Forces after the Gryps war, the surviving Nemos used by these two groups were brought over as well. These Nemos continued to be deployed by the Earth Federation Forces even in UC 0096, and were repainted in new color schemes that differ depending on operating locations. By this time, the almost decade old Nemo was no longer a front line unit, but still saw action fighting Zeon Remnants during their attacks on Dakar and Torrington Base with limited success.
