The underwater directional vehicle which is uprightly placed and propelled by rocket is a new kind of vehicle. In this paper, we present a method for establishing its mathematical model, that is, its spatial ballistic equation. Our model is based on the energy of the underwater vehicle as described in eq.(3). After a lengthy derivation, we get eqs.(8) through (11) as the mathematical model. In our model, we take into account the influence of mass variation (eq.(10)) and water flow in the ocean (eq.(11)) on the ballistics, Figs.1 through 3 illustrate the simulation ballistics by our model. They show preliminarily that our model is correct.
