Abstract: The firing strategy of electromagnetic railgun against an air target within line-of-sight range is studied based on the adjustable characteristics of projectile speed. A 6-DOF exterior ballistic equation set and a hit probability model for single-shot and whole-route continuous-shot firing on air targets are established. The impacts of target distance and muzzle velocity on hit probability in the cases of single-shot firing and whole-route continuous-shot firing are analyzed. The results show that, during the single shot firing, the higher the muzzle velocity is, the higher the hit probability is. In the whole-route continuous-shot firing, the cumulative hit probability increases first and then decreases with the increase in muzzle velocity, but there is local step-decreasing phenomena. A whole-route balanced firinging strategy, which is from the near to the distant, the highest single shot hit probability within effective range and multiple multiround simultaneous impact on the far side, can take into account the whole-route cumulative hit probability and the naval strike cost, and obtain a better operational effectiveness at a lower strike cost.
