Coordinated attack is the upmost cooperative style of the cooperative aerial combat, fire control of weapon launch is the foundation of coordinated attack. Command targeting method of weapon launch with friend fighter information sustain is proposed for the requirement of coordinated weapon launch. Firstly, a vector model of coordinated targeting is established, and targeting command computing method as well as targeting control method is given based on the space location and gesture locating information. Then, a targeting precision analysis model is established based on the precision of target information, fighter space location, and information delay as well as the targeting posture, and the application requirement is given. Finally the simulation result shows that the targeting information and fighter location precision have a direct influence on the coordinated attack effect, and the enhancement in the performance of fighters is the key factor to improve the efficiency of coordinated attack.
