US Navy tests world's largest self-driving warship: 132ft-long 'Sea Hunter' drone will scour oceans for enemy subs

The military is launching tests on the world's largest unmanned surface vessel. Dubbed the'Sea Hunter', the 132ft ship is designed to travel thousands of miles out at sea without a single crew member on board. Experts say the vessel has the potential to revolutionise not only the military's maritime service but also commercial shipping. The 132ft-long (40-metre) unarmed prototype, dubbed Sea Hunter, is the naval equivalent of Google's self-driving car, designed to cruise on the ocean's surface without a crew.
