Beyond-visual-range (BVR) air-to-air unmanned aerial vehicles (UAVs) combat has complex and varied characteristics. It always performs in a multiple UAVs cooperative way. This paper proposes a BVR air-to-air combat tactical strategy for multiple UAVs to achieve effective confrontations. The strategy is implemented by incorporating several one-versus-one air-to-air combat cases. For each one-versus-one case, a decision action space and a situation assessment function are developed. Then a minmax method based decision algorithm is designed to obtain the optimal tactic. Afterwards, to realize the optimal tactic, flight controllers for each UAV are designed. The superiority of the proposed BVR air-to-air combat tactical action decision strategy is validated by simulations in three representative scenarios.
