The G-3 was a testbed for the magnet coating technology later applied to Amuro Ray's RX-78-2 Gundam and future RX-78 series units. It was equipped with the NICN system, the newest version of learning computer that was also used in the RX-78NT-1 Gundam NT-1. In addition, the laser accelerator for its thermonuclear reactor was also replaced with a new one, which gave the G-3 twice the maneuverability of the RX-78-2. Visually, the G-3 is very similar to the Gundam, except for its gray and light purple paint scheme, intended to lower visibility.

During the attack on Side 7 in September UC 0079, the RX-78-1 Prototype Gundam was destroyed, but the RX-78-3 was only lightly damaged. It was loaded onto the Pegasus-Class assault cruiser White Base as spare parts for the intact RX-78-2 Gundam. After that, there were two different accounts of what happened.

In the first version, the RX-78-3 was recovered around the time of Operation Odessa and transferred to Augusta Lab, where it become the testbed for the magnet coating treatment. It exchanged data with the RX-78NT-1 Gundam NT-1, which was being developed in parallel, before being transferred into space.
