Late in the One Year War, the Earth Federation Forces produced the RX-78-2 Gundam, a mobile suit capable of independent atmospheric reentry. In response, Principality of Zeon engineers created the MS-06 Zaku Atmospheric Reentry Test Type. The Test Type mounted wave shields on its back, vernier thrusters all over its body, and attitude control boosters. To avoid a temperature rise inside the body, it was entirely covered with a ceramic coating, and its inner parts were equipped with a cooling system.
