Huntington Ingalls' Undersea Solutions Group showed off its Proteus mini submarine at the Navy League’s 2015 Sea-Air-Space Exposition.
The potent-looking vessel can serve as a unmanned underwater vehicle or a manned swimmer-delivery system. The battery-powered Proteus can carry six combat swimmers 350 to 700 nautical miles, depending on the type of battery used, according to USG officials.
The wet sub measures 310 inches x 63.5 inches x 64 inches and weighs 8,240 pounds.
Proteus has a top speed of 10 knots. Undersea Solutions Group is the prime, working with Battelle and Bluefin Robotics on Proteus.
