The RGM-89ST2 ST Gun was a custom reconnaissance suit tasked with collecting data on SNRI’s new prototype, the F90 Gundam F90. It followed the RGM-89ST1 ST Gun, which SNRI created by modifying a standard Anaheim Electronics RGM-89J Jegan Type J. The RGM-89ST2 was similarly created from a Jegan Type J by fitting its head with an enlarged forehead sensor; a radome and various cameras and sensors were also mounted on the shoulders. As the ST-Gun was not intended for combat, its armaments were limited to a 100mm machine gun and two 3-tube grenade launchers. In UC 0120, the Zeon remnants known as the Oldsmobile Army stole Gundam F90 Unit 2 during testing and took it to their Mars base. The ST-Gun and pilot Navi were part of the team that traveled to Mars on the Admiral Tianem to chase the Zeon. During a battle on the surface of Mars, the ST-Gun was immobilized and captured by the Zeon for its treasure trove of data. Navi was later able to escape the Zeon base, but was forced to leave her suit behind, which was presumably destroyed along with the base.
