The development of a prototype rocket launcher vehicle 122 calliber has begun in 2017-2019, by being carried out in stages and separately. So, it takes an effort in the development review every year, as well as an analysis of the suitability of the design requirements on the resulting prototype. The research method used is a qualitative method with a case study approach. In this study, the results of the review showed that the prototype of the X rocket launcher vehicle was in accordance with the required requirements. This refers to the 4 (four) design requirements, namely, an appropriate support and slide delivery system, an appropriate turret system, an appropriate transporter system and an easy and safe operating system.
