DjokoAndreas NavalinoY.H.YogaswaraWeaponry Technology Study Program, Faculty of Defense Technology, Indonesian Defense UniversityR-Han 122 B has been certificated by the Ministry of Defense as a weapon system. However, the Indonesian Navy Marine Corps has not used R-Han 122 B in order to support their task. The research was carried out to analyze the suitability of ballistic rocket requirements based on Indonesian Navy Marine Corps with the R-Han 122 B ballistic rocket, analysis based on system engineering of R-Han 122 B. This research is qualitative with interview to LAPAN, PT Pindad and the Indonesian Navy Marine Corps, literature study and observation. The results showed that the requirements of R-Han 122 B were different with Indonesian Navy Marine Corps. R-Han 122 B Propellant is HTPB composites to cause thick smoke. Meanwhile, the ballistic rockets used by Indonesian Navy Marine Corps (RM 70 Grad) use a double base solid propellant so that the smoke is thin. The flight stability R-Han 122 B has not yet grouped. The development of R-Han 122 B has not followed system engineering stage because there are no document requirements from user and the development stages have not been traced based on system engineering. The technology readiness level of R-Han 122 B rocket is at 7th level it means a demonstration ofprototype system is in the real environment. As a recommendation, the development should be following system engineering and it is need to improve the thrust, geometry and inertia of rocket/center of gravity and atmosphere studies, so that R-Han 122 B could be grouped.
