Presented here is the patented diver propulsion system used by the U.S. military for combat swimmer applications. This design currently requires a purchase approval from the U.S. Department of State.
The system’s 6″ diameter thrusters attach to the outside of a diver’s lower thighs, just above the knees, and the power source and throttle setting secures around the waist. The silent brushless electric motors allow a maximum underwater speed of 3.5-knots as well as a powerful operation of the diving fins to controlling attitude and direction. The operation of the thrusters is hands-free which makes them perfect for military reconnaissance, search and rescue operations, and hull inspections.
A lithium-ion battery provides a range that exceeds two miles. An extra battery may be carried and ‘hot swapped’ underwater to extend operation.
If you want to buy a pair, it will cost you $31,500.
