Aspects of the invention relate to an electrical linear motor propulsion system and method for propelling an object through a medium. According to one aspect of the invention, the electrical linear motor comprises electrical windings and permanent magnets in close proximity so that electrical current energizing the coil windings creates an electromagnetic field which interacts with the magnetic field of the magnets to cause reciprocating linear motion of an movable linear motor thruster subassembly within a guide tube, the reciprocating linear motion comprising a fast back stroke when thruster subassembly check valve is open, and a working stroke, when a check valve is closed, that discharges the medium from the guide tube, thereby propelling the object (e.g., marine vessel, submarine, torpedo, etc.) through the medium. The linear motor(s) can be attached to the marine vessel, in multiple ways. For example, the electrical linear motor(s) can be disposed within the marine vessel. Alternatively, the electrical linear motor(s) can be attached externally to the vessel by a rotatable shaft so that the propulsion linear force vector can be positioned in any direction (360 degrees along a plane). Additionally, the electrical linear motor(s) can be attached to the vessel by using a rotatable shaft and a coupling hinge connected to the electrical linear motor housing, thereby permitting positioning of the vessel propulsion linear force vector in any direction with three degrees of freedom.
