As described in the MG model manual and MS encyclopedia, during the postwar years the Federation received information that the Zeon remnants could have been developing mobile suits with nuclear capabilities. As a countermeasure, the Federation decided to develop a nuclear capable mobile suit of their own, and the result was the RX-78GP02A Gundam "Physalis".
While the production and development of the RX-78GP02A was a violation of the Antarctic Treaty, it's a moot point at best. The Antarctic Treaty was signed by the Principality of Zeon which was replaced by the Republic of Zeon, following the end of the One Year War, rendering the treaty itself an agreement with a now non-existent government. Delaz cited the RX-78GP02A as a violation of the Antarctic Treaty primarily to illustrate the underhanded dealings of the Earth Federation.
Despite being one of the largest Gundams in UC history by armor volume, the GP02A is highly maneuverable. Besides the nuclear warhead, the Physalis is armed with standard head-mounted vulcan guns and two torso- mounted beam sabers, which when activated glow green instead of the normal pink. The GP02 was designed to possibly work in tandem with its brother unit, the GP01.
