Unmanned swarm test evaluation is an important bridge that promotes unmanned swarm technology from theory to practice. Compared with traditional combat systems， unmanned swarm systems have the characteristics of autonomous coordination， emergence of capabilities， and intelligent countermeasures. These have greatly exceeded the scope of traditional combat system test evaluation. In response to the above-mentioned practical needs， this paper summarizes the groundbreaking work of advancing swarm test evaluation in the United States and China， and discusses the concept and development status of unmanned swarm test evaluation. Based on our previous research on aviation swarm operations， we also explore the main content and feasible technical route of unmanned swarm test evaluation， which will lay the foundation for the information upgrade and intelligent transformation of military equipment.
