The RB-79 Ball is a fictional weapon from the anime series Mobile Suit Gundam.
The Federation refitted about 1200 of the civilian-model worker space pods, known as SP-W03 Space Pods. The Federation reinforced it with heavier armor and mounted a 180mm low-recoil cannon on top. The Ball mobile pod also had vernier thrusters mounted all along the body.
The concept for a combat mobile pod was initially devised as early as U.C. 0076 under the RX-76 project. However, development was put on hold until February 13, U.C. 0079, where the project was revived with renewed interest. The first RB-79 Ball was rolled-out in June of U.C. 0079. During the outbreak of the One Year War between the Earth Federation and the Principality of Zeon, the Federation lacked any sort of the mass-produced humanoid mecha, known as Mobile Suits. The Zeonic forces laid waste to the Federation with their mobile suits, the MS-05B Zaku I and the later MS-06F Zaku II.
