The U.S. Navy Just Took Delivery of the World’s Largest Roboship

From Popular Mechanics:

The U.S. Navy accepted delivery of a revolutionary uncrewed surface ship, one capable of traveling long distances and conducting missions all without a human on board. The Sea Hunter Anti-Submarine Warfare Continuous Trail Unmanned Vessel—or ACTUV for short—could someday lead to fleets of unmanned warships plying the world’s oceans, doing everything from hunting submarines to acting as spy ships.

The U.S. Navy ordered the ACTUV in 2012 as part of the Pentagon’s broader push into unmanned air, sea, and land systems. It was envisioned as a platform to test the autonomous concept in surface ships, explore how to safely and securely operate unmanned ships for months at a time over thousands of nautical miles, and create a vessel capable of tracking enemy diesel-electric submarines.

Built at the Christensen Shipyards in Vancouver, Washington, the 132 foot long, 140 ton ship is the world’s largest uncrewed ship. The pilothouse, necessary for a human crew to control the ship, can be unbolted and removed. The ACTUV has a single hull with two outrigger floats to enhance stability at sea, and has a maximum reported speed of 27 knots. From above the ship looks like a Klingon Warbird, its hull and two floats slicing through the water, leaving three wakes....MORE
