A system for enhancing control of an underwater vehicle, and providing a quick change modular payload section includes a motor configured to rotate an internally threaded member threadingly engaged with a threaded rod. Rotating the member creates linear motion of the threaded rod. A control rod connected to the threaded rod provides movement of a rudder or fin. The threaded rod and member are configured with threads having a fine pitch which maintains a stable position of the fins without needing to supply power to the motor for adjustments. The modular payload arrangement includes a bulkhead ring having L-shaped recesses that receive fasteners disposed on a central body section. The payload section may be fastened to the vehicle by pressing the payload section onto the central body such that the fasteners align with the recesses and turning the payload section to secure the payload section.

1. A system for controlling an underwater vehicle, comprising: a linear control assembly comprising a motor and a threaded rod, the motor engaged with an internally threaded member that is threadably engaged with and surrounding the threaded rod;a control rod connected to the threaded rod;a fin assembly connected to the control rod;a sensor for sensing a position of the threaded rod; anda control system configured to compute an angular position of the fin assembly based on a sensed position of the threaded rod,wherein actuation of the motor rotates the internally threaded member, thereby causing a linear movement of the threaded rod, the control rod, and the fin assembly. 2. The system of claim 1, wherein the fin assembly is rotatably connected to the control rod such that a linear movement of the control rod rotates the fin assembly. 3. The system of claim 1, wherein the sensor comprises a rheostat. 4. The system of claim 1, the control system including a processor in communication with the sensor, to control the underwater vehicle to perform a desired action. 5. The system of claim 1, further comprising a global positioning system (GPS) in communication with the control system, wherein the control system is configured to instruct the motor to adjust a position of the fin assembly based on a signal received from the GPS. 6. The system of claim 1, further comprising a compass in communication with the control system, wherein the control system is configured to instruct the motor to adjust a position of the fin assembly based on a signal received from the compass. 7. The system of claim 1, further comprising an inertial measuring unit (IMU) in communication with the control system, wherein the control system is configured to instruct the motor to adjust a position of the fin assembly based on a signal received from the IMU. 8. A system for controlling an underwater vehicle, comprising: a linear control assembly comprising a motor and a threaded rod, the motor engaged with an internally threaded member that is threadably engaged with and surrounding the threaded rod;a control rod connected to the threaded rod;a fin assembly connected to the control rod; anda spring calibrated to compensate for forces of seawater pressure on said linear control assembly and linkage rods, said spring engaged with and providing a pre-load on the threaded rod that acts in a direction opposite to the load applied by the sea,wherein actuation of the motor rotates the internally threaded member, thereby causing a linear movement of the threaded rod, the control rod, and the fin assembly. 9. The system of claim 1, wherein the fin assembly includes an elevator or a rudder. 10. A modular payload system for an underwater vehicle having a payload section and a central body section, the system comprising: a payload section having a bulkhead section, anda central body section, the central body section having a circumferential lip portion and a plurality of fasteners circumferentially disposed on the lip portion, wherein at least one of the plurality of fasteners comprises an increased diameter head that is larger than an opening dimension of the respective transversely disposed locking section; andwherein the central body section is engageable with the bulkhead section by aligning the plurality of fasteners with the axially-disposed openings of the recesses, pressing the bulkhead section toward the central body portion, and twisting the bulkhead portion with respect to the central body portion to engage the plurality of fasteners with the transversely disposed locking sections of the plurality of recesses. 11. The system of claim 10, wherein the payload section comprises a payload selected from the list consisting of sound simulation equipment, a sensor, a camera, a Doppler velocity log, an uplooking sonar, and a conductivity-temperature-density measuring device. 12. The system of claim 11, further comprising a payload processor in communication with the payload and with a main processor of the underwater vehicle, the payload processor configured to transmit data to the main processor based on signals received from the payload. 13. The system of claim 11, further comprising a wireless or satellite modem in communication with the main processor for offloading data obtained from the payload. 14. The system of claim 11, wherein the communications between the payload processor and the main processor are wireless. 15. The system of claim 10, further comprising a removable battery disposed in the central body section. 16. The system of claim 15, wherein the removable battery is rechargeable. 17. The system of claim 12, wherein the payload processor comprises a wireless transmitter configured to transmit signals to, and receive signals from, at least one other underwater vehicle. 18. The system of claim 8, wherein said spring is a coil spring. 19. The system of claim 8, further comprising a sensor for sensing a position of the threaded rod. 20. The system of claim 19, further comprising a control system including a processor in communication with the sensor, the control system configured to compute an angular position of the fin assembly based on a sensed position of the threaded rod.
