A plasma drive includes a plurality of plasma thrusters arrayed in each of at least one array of plasma thrusters. Plasma thrust may be generated sequentially or in a pulse from each array. Circuitry is adapted to selectively fire each thruster in each array according to a digitally controlled progression. The controlled firing progression collectively provides a cumulative thrust vector for each array. In a turbine drive embodiment the controlled progression causes sequential firing of the thrusters in each array, and the arrays in sequence. The controlled progression allows for directional control of the combined cumulative thrust vectors.
