The Core Block System allows the Gundam AGE-3 to be separated and re-combined in emergency situations as well as to change its G-Wears without the requirement of AMEMBO to transport the wear parts. However at the present stage, both the Core Fighter and the G-Wears require a pilot each for successful docking. The Core Fighter was later reconfigured at Flit's request so it can operate using one pilot.
The Gundam AGE-3 has a unique Wear system in the form of G-Wear, a transformable unit that can dock with the Core Fighter to form different version of the Gundam. The G-Wear for the AGE-3 Normal is the G-Cepter, while the the G-Hopper and G-Viper are for the the AGE-3F Gundam AGE-3 Fortress and AGE-3O Gundam AGE-3 Orbital respectively. Each G-Wear has its own cockpit, allowing it to be piloted for launch and activation. An auto-pilot system is present for the alignment and docking with the Core Fighter.
