Anti-submarine ships disposition model of aircraft carrier formation should be built on the basis of the use of the towed linear array sonar and the operational characteristics of the aircraft carrier formation. Aiming at the use of the towed linear array sonar, this paper proposed method to determine the smallest distance between anti-submarine ships and measures to make up the dead zone of the towed linear array sonar. Then, model of anti-submarine ships disposition was advocated by using of the analytical method, taking the consideration of anti-submarine ships’missions during navigation and in combined operational areas. Based on this, the model was analyzed and proved through simulation with reasonable parameters designed. The results show that the model can provide anti-submarine ships disposition model of aircraft carrier formation with reference.
