Orca Extra Large Unmanned Undersea Vehicles (XLUUVs)

The Orca is based on the Echo Voyager technology demonstration sub. That boat is an unmanned diesel electric submarine launched and recovered from a pier. It has a range of 6,500 nautical miles and can run completely alone for months at a time. It measures 51 by 8.5 by 8.5 feet and has a weight “in the air” of 50 tons.
The sub features an inertial navigation system, depth sensors, and can surface to get a fix on its position via GPS. It uses satellite communications to “phone home” and report information or receive new orders. Echo Voyager can dive to a maximum depth of 11,000 feet and has a top speed of eight knots.
One crucial piece of Echo Voyager is the modular payload system that allows it to take on different payloads to support different missions. The unmanned sub has an internal cargo volume of 2,000 cubic feet with a maximum length of 34 feet and a capacity of eight tons. It can also support external payloads hanging off the hull.
