A mechanism for retrofitting a turret that has a manual rotation system with a motorized turret rotation system includes a gear box mechanically coupled to the turret, an electrically powered prime mover unit mechanically coupled to the gear box, a user operated control device electrically coupled to the prime mover unit, and an electrical power supply electrically coupled to the prime mover unit. The turret rotates relative to a body structure. The gear box and the prime mover unit are mounted to the body structure. The control device and the electrical power supply are positioned on the turret. The power supply provides electrical power to the prime mover. The control device presents a control signal to the prime mover when the user actuates the control device, and the turret rotates in response to the control signal.

The invention claimed is: 1. A mechanism for retrofitting a turret that has a manual rotation system with a motorized turret rotation system, the mechanism comprising: a gear box mechanically coupled to the turret; an electrically powered prime mover unit mechanically coupled to the gear box; a user operated control device electrically coupled to the prime mover unit; an electrical power supply electrically coupled to the prime mover unit, wherein the turret rotates relative to a body structure, the gear box and the prime mover unit are mounted to the body structure, the control device and the electrical power supply are positioned on the turret, the power supply provides electrical power to the prime mover, the control device presents a control signal to the prime mover when the user actuates the control device, and the turret rotates in response to the control signal; and an electrical power source that is positioned on the body and electrically coupled to the power supply via mating electrical connector halves that are disengagable in response to a predetermined tension force, a first tether connected to a first respective half of the connector halves and the body and a second tether connected to a second respective half of the connector halves and the turret, wherein the electrical power source provides a charging current to the power supply, and the tethers are sized such that when the turret is rotated beyond a predetermined range, the tethers provide a tension force that exceeds the predetermined tension force. 2. The mechanism of claim 1 wherein the mechanism is implemented as a replacement for the manual rotation system. 3. The mechanism of claim 2 wherein existing holes and mounting locations for the manual rotation system are used to eliminate additional holes or brackets for installation of the mechanism. 4. The mechanism of claim 1 wherein the mechanism is implemented in connection with an M-1114 High Mobility Multipurpose Wheeled Vehicle (HMMWV) turret assembly. 5. The mechanism of claim 1 further comprising a motor controller mounted to the turret and electrically coupled to the control device, the power supply, and the prime mover unit, wherein the control device presents the control signal to the controller, the controller presents the control signal to the prime mover and the electrical power to the prime mover in response to the control signal, the electrical power is presented to the prime mover in proportion to an amount of actuation of the control device, and the turret rotates at a speed that is proportional to the electrical power. 6. The mechanism of claim 1 wherein the prime mover unit comprises a brake, an electric motor, and a clutch all of which receive the electrical power and the control signal, and during a normal mode of operation, the brake is disengaged, the motor rotates, and the clutch is engaged in response to the electrical power and the control. 7. The mechanism of claim 6 wherein the clutch is manually disengagable when the prime mover is non-functional to provide manual rotation of the turret. 8. The mechanism of claim 1 wherein the power supply is positioned on the turret substantially opposite additional equipment that is mounted on the turret to provide counter balancing to the additional equipment. 9. The mechanism of claim 1 wherein the power supply comprises at least one battery having a full charge capacity sufficient to operate the turret during a predetermined patrol cycle without being recharged. 10. A method of retrofitting a turret that has a manual rotation system with a motorized turret rotation system, the method comprising: mechanically coupling a gear box to the turret; mechanically coupling an electrically powered prime mover unit to the gear box; electrically coupling a user operated control device to the prime mover unit; electrically coupling an electrical power supply to the prime mover unit, wherein the turret rotates relative to a body structure, the gear box and the prime mover unit are mounted to the body structure, the control device and the electrical power supply are positioned on the turret, the power supply provides electrical power to the prime mover, the control device presents a control signal to the prime mover when the user actuates the control device, and the turret rotates in response to the control signal; and positioning an electrical power source on the body and electrically coupling the electrical power source to the power supply via mating electrical connector halves that are disengagable in response to a predetermined tension force, connecting a first tether to a first respective half of the connector halves and the body and a second tether to a second respective half of the connector halves and the turret wherein the electrical power source provides a charging current to the power supply, and the tethers are sized such that when the turret is rotated beyond a predetermined range, the tethers provide a tension force that exceeds the predetermined tension force. 11. The method of claim 10 wherein the mechanism is implemented as a replacement for the manual rotation system. 12. The method of claim 11 wherein existing holes and mounting locations for the manual rotation system are used to eliminate additional holes or brackets for installation of the mechanism. 13. The method of claim 10 wherein the method is implemented in connection with an M-1114 High Mobility Multipurpose Wheeled Vehicle (HMMWV) turret assembly. 14. The method of claim 10 further comprising mounting a motor controller to the turret and electrically coupling the motor controller to the control device, the power supply, and the prime mover unit, wherein the control device presents the control signal to the controller, the controller presents the control signal to the prime mover and the electrical power to the prime mover in response to the control signal, the electrical power is presented to the prime mover in proportion to an amount of actuation of the control device, and the turret rotates at a speed that is proportional to the electrical power. 15. The method of claim 10 wherein the prime mover unit comprises a brake, an electric motor, and a clutch all of which receive the electrical power and the control signal, and during a normal mode of operation, the brake is disengaged, the motor rotates, and the clutch is engaged in response to the electrical power and the control. 16. The method of claim 15 wherein the clutch is manually disengagable when the prime mover is non-functional to provide manual rotation of the turret. 17. The method of claim 10 wherein the power supply is positioned on the turret substantially opposite additional equipment that is mounted on the turret to provide counter balancing to the additional equipment. 18. The method of claim 10 wherein the power supply comprises at least one battery having a full charge capacity sufficient to operate the turret during a predetermined patrol cycle without being recharged.
