A prototype mobile suit developed by the Zeonic Company, it is a modified version of the MS-07H Gouf Flight Test Type unit 4. The engines in the legs have been replaced with newer models, and ventral fins have been added to the waist. The spike armor on both shoulders has been removed and replaced with winged armor. These improvements extended its flight time and gave it good maneuverability, but the engines were difficult to adjust.
After four weeks, test-flight accidents left only one Gouf Flight Type functional. This unit was then given various modifications to improve its performance, and assigned a new model number, MS-07H-4, to reflect the changes in design. However, on its tenth day of flight testing, the Gouf Flight Test Type experienced massive engine failure and exploded in mid-air, killing test pilot Frank Bernard. Following the accident, Zeon's official flight-type mobile suit development programs were all immediately cancelled.
