潜艇作战的特点是隐蔽接敌，出其不意地给目标以致命的大击，其隐蔽性直接影响潜艇的战斗力和生存能力。文中提出了隐蔽势的概念，并利用动态规划方法研究了潜艇占领射击阵位的最优隐蔽机动航路，其结论与常规经验是完全一致的． Submarine combat is characterized by covert access to the enemy, by surprise to the target of a fatal blow, and its covert submarine directly affect the combat effectiveness and viability. In this paper, the concept of hidden potential is proposed, and the optimal concealed maneuvering route of submarine occupying firing position is studied by using dynamic programming method. The conclusion is consistent with the conventional experience.
