G Project (Conflicted Hearts)

The G Project but is also known as the G-Weapon Project, is a Mobile Suit development project in the Cosmic Era timeline, spearheaded by the Earth Alliance. Its primary objective initially was to develop state-of-the-art new-generation prototype Mobile Suits, which would allow the Alliance to eliminate the current advantage held by ZAFT's mobile suits.

Earth Alliance/OMNI Enforcer Suits
The Earth Alliance prototype mobile suits developed under the G-Project bore the prefixing designation "GAT-X" (Gressorial Armament Tactical - eXperimental), occasionally heard or referred to as "G-Weapons". Later production-model mobile suits derived from the prototypes retained only the "GAT-" prefix designation.

First Generation: Heliopolis
The first set of prototype mobile suits were jointly developed by the Alliance and Orb's Morgenroete, Inc. at the Orb space colony Heliopolis. Of the 12 prototypes developed, seven were captured by ZAFT.
