During its military reconstruction following the devastating One Year War, the Earth Federation Forces contracted a private company, Anaheim Electronics, to develop a series of new Gundam-model mobile suits to serve as conceptual testbeds for new and improved mobile suit technology. The third of these new prototypes to be produced by Anaheim was the RX-78GP03 GP03 Gundam, codenamed Dendrobium. The Dendrobium was composed of two units: the RX-78GP03S Gundam mobile suit itself, codenamed Stamen; and the large RX-78GP03 mobile weapon unit, codenamed Orchis. The Orchis was an unmanned unit, and required the Stamen – which itself had a pilot – to be docked with it for it to function. Since the GP03 Dendrobium was designed as a defense unit for space installations capable of taking on enemy mobile armor, the Orchis component was basically a large space-going vehicle, equipped with enough thrusters to make it a fast interception unit. Its primary heavy armament was a large mega beam cannon, mounted on its own movable arm for aiming, and it also had two large claws which incorporate large beam sabers capable of slicing up something as large as a battleship. The Orchis also mounted an external I-field barrier generator, giving the GP03 complete 360-degree protection from enemy beam weapons fire. For versatility, it also mounted two large weapons container pods, which could carry a variety of weapons from micro-missile launcher pods to battleship-sized demolition chain mines. Spare weapons containers could be loaded out ahead of time, and the Orchis could have empty pods changed out for new ones in a matter of minutes.

The Stamen was completed at Anaheim’s Von Braun City lunar factory and delivered to their La Vie en Rose dockship, where the Orchis component was also completed. The only thing left to make the GP03 field-ready was piloting and combat data. However, with the shutdown of the Gundam Development Project, EFF security officer Nakahha Nakato dismissed all of the Anaheim research staff except for systems engineer Lucette Audevie. With the threat of the Delaz Fleet and the impending colony drop crisis, Lucette strongly argued for the GP03’s completion, all to no avail. To face this desperate situation, Gundam pilot Kou Uraki and the crew of the assault carrier Albion hijacked the GP03 – with the assistance of Lucette (and at the cost of her life) – and quickly fielded the Dendrobium, proving to be a devastating foe to the Delaz Fleet escorting their hijacked colony falling towards Earth. The Orchis was heavily damaged by Anavel Gato’s AMX-002 Neue Ziel in battle, and further damaged when it was caught in the path of the EFF’s own Solar System II. However, both Kou and the Stamen survived.
