Abstract:Underwater preset weapon is researched extensively in the world as a new underwater armament. In this paper, the typical combat procedure of underwater preset weapon and anti-ship combat models of underwater preset group are studied, 12 combat cases between underwater preset group and aircraft-carrier formation are simulated, combat operational characteristics and mechanisms such as attacking direction, launching distance, firing mode, target sequence and combat opportunity of underwater preset group are analyzed according to the simulation results, as the conclusion, corresponding combat operational strategies of underwater preset group are presented. It maybe provides theoretical reference for the combat operation and subsequent development of underwater preset weapon.
