A model of air and missile defense system network is built up by adopting HK complex network model, and its degee distribution, clustering coefficient and average path length are studied. Compared the statistical characteristics of this model with those of the typical air and missile defense system network based on small-world networks, the result shows that the air and missile defense operational network based on HK complex network model has a good clustering coefficient and scale-free property. And simultaneously the model has more TF probability, and can also provide more advantages for the personnel in special field to design the air and missile defense system network
