In its efforts to create a dominant land use mobile suit, the Zeon's Zimmad Company took a standard MS-07 Gouf and extensively modified it. The new unit they created was dubbed the Gouf Test Prototype. The Gouf Test Prototype mounted several extra thrusters in its legs to give it the ability to hover short distances across the ground. It was also given an experimental heat sword melee weapon that was substantially larger than the normal Gouf heat saber.
Only a single Gouf Test Prototype was constructed during the One Year War, and it was used explicitly as a testbed for new innovations in mobile suit design, never seeing any actual combat. The data gathered from the Gouf Test Prototype would be compiled and several of the new technologies that were tested with it would become standard issue when the Zimmad Company created their next mobile suit, the MS-09 Dom.
