Abstract:	In order to occupy the position, escape the enemy or evade enemy attacks, a submarine usually maneuvers at a high speed, changes the depth with a large trim or changes the course with a large rudder. This process of high speed depth or direction change is called strong maneuvering. However, strong submarine maneuvering is accompanied by manipulation risks. In the course of strong maneuvering, the submarine moves at a high speed and has a large rudder angle, resulting in an exponential increase in its hydrodynamic force and hydrodynamic torque. Once buoyancy loss and rudder jam occur, it poses a great threat to the survivability of the submarine, and seriously restricts its combat effectiveness. Therefore, it is valuable to research rescuing methods of a submarine during underwater strong maneuvering. This paper is based on a mathematical model of strong maneuvering of a submarine and submarine rescuing methods during buoyancy loss as the research objects. It provides manipulating suggestions of strong maneuvering through a comprehensive analysis of the three rescuing methods according to mathematical modeling, simulation research and effectiveness evaluation.
