In the age of the Internet of Things (IoT), satellite launching has become more common than in the past decades. To date, the rocket system is the only means of bringing satellites into Earth’s orbit. However, the technology is very localized, and Malaysia is still in an embryonic stage. The main motivation is to produce a reliable rocket motor using relatively cheap and easily available resources. In this thesis, the best manufacturing casting method that yields more than 95% density ratio was studied for KNSB sugar-based propellant. The N-Class SRM was fabricated, tested and discussed. Each propellant manufacturing method was repeated for three samples and the sample density was calculated. The fabricated SRM was static test fired and the results were discussed with root cause analysis. The results were compared with the theoretical and discuss. The findings from the test static test show that the ejection of the nozzle during the static firing test is most probably case by the external and internal voids caused by the manufacturing method. The suggested method is to change from cartridge form to case-bonded propellant and use compression during casting to remove the internal air bubble that produced internal voids
