Raytheon’s rival XOS mechwarrior suit, which at last report still trails an inconvenient power cable to the nearest wall socket.
* Soldiers will be able to carry loads up to 200 pounds with minimal effort
* HULC uses four pounds of lithium polymer batteries will run the exoskeleton for an hour walking at 3mph, according to Lockheed. Speed marching at up to 7mph reduces this somewhat; a battery-draining “burst” at 10mph is the maximum speed
A soldier with a pack would normally go at 3 mph maximum and cover 10-12 miles in a day.
* Remote-controlled gun mounts weighing as little as 55lb are available, able to handle various kinds of normally tripod- or bipod-mounted heavy weapons
* there’s an extended-endurance HULC fitted with a “silent” generator running on JP8 jet fuel. A tankful will run this suit for three days, marching eight hours per day
* HULC is basically a legs and body system only: there’s no enhancement to the user’s arms, though an over-shoulder frame can be fitted allowing a wearer to hoist heavy objects such as artilery shells with the aid of a lifting strop.
NOTE: Average humans walk 4 to 6 mph, but special operations soldiers are often expected to carry up to 150 pounds of supplies in their backpacks. 25mph speed with bionic boots (springing the step) would be covering almost a marathon distance in one hour.
