In the year U.C. 0067, several scientists and researchers are developing a "Robot System", or "RS", large general-purpose machines equipped with powerful reactors. These RS machines served as distant ancestors to mobile suits, and were developed at Ryanto Heavy Industries, located in the United States. RS were designed for interstellar travel, when humanity would one day leave the Solar System. Much of the basic research completed by Ryanto was later referenced by the Earth Federation during Operation V.
These researchers would later join the two sides of conflict during the One Year War in U.C. 0079 (in Outer Gundam U.C. 0079 is referred to as the equivalent to 2047 AD).
In U.C. 0079, the Earth Federation begins development on an unmanned mobile suit piloted by an A.I., as part of Operation V. The resulting mobile suit is the RX-78EX-PH-1 Zephyr Gundam, with its performance based on the RX-78-2 Gundam. However, with no pilot to have to account for, the performance of the Zephyr Gundam can be pushed to its limits.
