The dynamics model of missile sealifts system for navy ships connected parallely is established. The dynamics simulation analysis of system is studied. The dynamics characteristic of missile box on the condition of different sea states and place parameters of crane are analyzed. The theory and technology bases for the design of system of missile sealifts or navy ships connected parallely are presented. The controlled multibody system dynamics of the system of missile sealifts with wave compensation for navy ships connected parallely is presented. On the condition of stochastic momevement of depot ship and incept ship and under the action of sealifts and wave compensation, the dynamics of sealifts system is studied by using discrete time transfer matrix method of multibody system. The calculate method of electric machine impule is developed in the process of supplying missile and action of wave compensate. Based on the PLC control system, the control method, which control supply process by testing torque of guide strings is presented.
