Technology & Combat Characteristics
Developed from the YMS-15 Gyan for actual combat, two prototypes were constructed. Its name is derived from the "Goddess of Dawn" in Greek mythology. Its mobility in space is improved by equipping a Gelgoog backpack (randsel), apparently a High Mobility Type. The Gyan Eos carries a Beam Bayonet which mounts a small beam gun. The shield missile launchers are omitted in-order to improve its defensive performance.
- Custom Shield
- Although it has similar dimensions to the original Gyan's shield, it lacks it's missile and bomb/mine loadout which increase it's defensive capability due to there being no chance of these munitions detonating within the shield. It has a large symbol of the Principality of Zeon on the center.
- Beam Bayonet
- A long rifle or spear-like weapon, the head of the weapon is lined with short beam blades, similarly to the later MS-15K Gyan Kai's beam sword.
- Beam Gun
- Attached to the middle of the Beam Bayonet is a Beam Gun that provides the Gyan Eos with ranged capability.
- Giant Bazooka
- The same Giant Bazooka used by the MS-09B Dom, this bazooka is magazine fed and holds 10 rounds per magazine, and a single round can blow the torso off of an enemy mobile suit.
