The paper proposes a solution to the problem of determining hydrodynamic loads on the rocket and submarine using numerical simulation based on the control volume method in a three-dimensional non-stationary problem statement. We took into consideration contours, rocket and submarine velocity, medium two-phase state (gas liquid), viscosity and gravity. We calculated the start effects on the rocket and submarine for two cases: when the submarine is moving and stationary. The reliability and accuracy of the calculations were confirmed by comparing them with the results of the tests on a model in the hydro tank at JSC Academician V. P. Makeyev State Rocket Centre.
