The invention is a submersible electric thruster that can be used to propel underwater vehicles, surface vehicles, amphibious vehicles, etc. The submersible electric thruster comprises a stationary stator assembly with a base, stator, windings, and bearings and an external rotor assembly comprising a cylindrical arrangement of permanent magnets with a hub that is secured to a shaft wherein the stator forms the center of the motor and the permanent magnets spin around said stator. A propeller hub is integrally connected to the rotor assembly with angularly spaced propeller blades extending radially from said propeller hub. An annular nozzle surrounds the propeller and motor, forming an inlet and outlet for water flow. A nose cone is connected to the stator assembly and a tail cone is integrally connected to the nozzle assembly. A plurality of supporting arms extends from the stator assembly to support the nozzle and a plurality of supporting arms extends from the nozzle to the support the tail cone.
