This paper aims to determine and study the effect of applying a lean manufacturing approach on reducing cycle time in producing tube cases of the product Sh-3 missile. Since the tube case is the critical part of the sh-3 missiles set and it represents the bottleneck of a Sh-3 missile, the overall cycle time & increasing productivity is depending on it. Lean  manufacturing is used to obtain the best resource utilization in various fields, in military manufacturing case, there are special conditions of operation and manufacturing which need a special deal and solutions, using the same tools of approach. In this article, waste analysis,
waste identification, and waste elimination were applied using (PDSA approach, 5s, 8 wastes, PokaYoka, visual management, Kaizen, SMED) tools, the optimum cycle time will be determined after applying this study and will be presented in terms of hours and percentage of the previous situation. Generally, the current situation shows that the tube case of the product sh-3 missile is produced in 51 working days with 8 working days between each product and other. The predicted results of this study giving about 10% reduction in the cycle time of the target product.
