Operational demand generation is an important traction for the development of weaponry and a fundamental guarantee for future threats and military struggles.The development context, research results and future development trend of equipment operations at home and abroad are studied.From the perspective of war design,the research on the generation method of weapon equipment operation demand is carried out.The research scope is extended from the traditional single equipment ring to three equipment rings,and the design content and equipment of the future war are clarified.Design elements of the generation of operational requirements are clearly identified.The practice analysis shows that the method of generating equipment operation demand based on war design is of good usability,comprehensiveness and scientificalness.It can guide the demonstration of the capability demand of equipment,the choice of technical scheme and the improved design,and support the improvement of the actual combat capability of the equipment in China.
