China Unveils New Unmanned Surface Vehicle, Claimed to Be the World’s Fastest | The Diplomat
Tianxing-1 , a high speed USV. A first glance you get the false impression it's a hovertank, but it's just a RHIB USV, I think...

The Microtransat Challenge
Interesting that IMO/COLREGS treats these autonomous sailing boats as either debris, or oceanographic monitoring buoys if equipped with oceanographic sensors. US Coast Guard basically doesn't care as long as they're under 8 feet in length, though there is confusion over whether they are using a 4m or 2.4m ruling.

MUNIN | MUNIN – Maritime Unmanned Navigation through Intelligence in Networks
Unmanned cargo ship research. Operationally a difficult proposition. Rolls-Royce has some ship designs for a high TEU cargo ship, but basically they look like a Maersk E-class with the accommodation/nav block replaced by another row of containers.

Marine Tech Factory - Propulsion
Interesting brushless DC motor design for underwater propulsors. On the face of it, I guess what they did was coat a conventional BLDC motor internals with some sort of waterproof coating, and fiddled with the shaft bearing seals. How well will it stand up to saltwater though?

UOV Vehicles
Interesting mix of technology here. A solarsailer wind wing sail with embedded solar cells for power, and a underside electric propeller that can operate in reverse generator mode when the wind is strong enough, to top off the batteries for the drone and the sensor platform/comm rig. As a USV, it probably is a equal to those wave rectifier sensor platform USV's, but with substantially better transit distance and directional performance. It would effectively be operating with no range limitation, provided you didn't blow too much battery before a normal recharge cycle.

Different from those submarine slocum gliders (AKA Iron Albatrosses), this one uses an underwater wing to rectify wave motion to provide propulsion.

A game to see if you can hunt subs well, using a stand-in unmanned drone vehicle. DARPA is basically crowdsourcing hunting strategies to codify into a tracking algorithm for the real drone, so it can go autonomous.
