At the conclusion of the One Year War, the Federation opened the Gundam Development Project, aimed at creating mobile suits superior to those that Zeon had developed. The RX-78GP01 Gundam “Zephyranthes” was the second of five Gundam type mobile suit prototypes completed under this plan.
The RX-78GP01 was designed to be an adaptable mobile suit, able to operate under any condition on earth or in space; to that end its design is superficially similar to the other RX series Gundams. Unlike previous suits, this was one of the first to re-introduce the core fighter concept in its design, utilizing the recently developed FF-XII Core Fighter II as the cockpit.
