Rolls-Royce Unveils Long-Range Autonomous Naval Vessel Concept

British engineering firm Rolls-Royce says it has developed a new autonomous, single-role, naval vessel concept.

The self-piloting surface vessel will have a range of 3,500 nm, displace 700 metric tons and have a top speed of more than 25 knots, according to a company release on Sept. 12.

The 200-ft (60-m) vessel will be able to conduct a variety of single-role missions, such as patrol and surveillance, mine-detection or fleet screening, says the company.
