‘Sea Hunter,’ a drone ship with no crew, just joined the U.S. Navy fleet

By Mark Austin Published February 4, 2018

A prototype autonomous ship known as the Medium Displacement Unmanned Surface Vehicle (MDUSV) has officially been transferred to the U.S. Navy from the Defense Advanced Research Projects Agency (DARPA) after a two-year testing and evaluation program. Named “Sea Hunter,” the Office of Naval Research will continue to develop the vessel from this point forward.

Although there’s no specific timetable for when the Sea Hunter would join active naval operations, the statement from DARPA indicated that it could happen as early as this year. The anti-submarine warfare vessel could be the first of an entirely new class of warship.

“[Sea Hunter] represents a new vision of naval surface warfare that trades small numbers of very capable, high-value assets for large numbers of commoditized, simpler platforms that are more capable in the aggregate,” said Fred Kennedy of DARPA. “The U.S. military has talked about the strategic importance of replacing ‘king’ and ‘queen’ pieces on the maritime chessboard with lots of ‘pawns.’”

The collaboration between the Navy and DARPA began in 2014, with the ship designed and developed by Virginia-based defense company Leidos, and christened in April 2016. A rigorous series of open-water tests followed, including surveillance and mine counter-measures.

According to Newsweek, the ship got its name from the mission the Navy envisions for it — stalking foreign submarines at sea. It’s relatively cheap to build at $20 million, and it’s far less expensive to run than a similar manned vessel.

“This is an inflection point,” former Deputy Defense Secretary Robert Work said in an interview with Reuters in 2016. “This is the first time we’ve ever had a totally robotic, trans-oceanic-capable ship.”

“I would like to see unmanned flotillas operating in the western Pacific and the Persian Gulf within five years,” he added.

The Navy hopes that ships of the future will be able to stay at sea for months at a time and travel thousands of miles without any crew. The Sea Hunter is currently a surveillance platform and has no weapons onboard. It’s 127 feet long and can reach speed of 27 knots, using cameras and radar to track its location and spot other ships.

Work went on to emphasize that if robot ships like Sea Hunter were outfitted with weapons in the future, there would always be a human at the controls. “There’s no reason to be afraid of a ship like this,” he said.

Kia America COO says ending EV tax credit would be dumb

kia coo ending ev incentive dumb zeta evs

With Kia just getting started with the expansion of its U.S.-made electric-vehicle (EV) lineup, the automaker may have a good perspective on what losing tax incentives on EVs could mean for the industry and the economy.

The transition team of the incoming Trump administration is reportedly planning to end the federal $7,500 tax credit on the purchase or lease of an EV. Under the Biden administration’s Inflation Reduction Act (IRA), an EV made in North America is eligible for the incentive.

Mercedes bets solar paint is part of EV-charging future

mercedes solar paint evs benz electric camper

It’s been said that Albert Einstein’s genius came from his ability to freely wonder and ask child-like questions way before he even tried applying science-based solutions.
It seems some within the R&D department at Mercedes-Benz might be similarly inspired. The German automaker is currently developing a special solar paint that, when applied on the surface of vehicles, can harness enough energy from the sun to power up EVs.
The energy generated by the paint’s solar cells can be used for driving or fed directly into a high-voltage battery.
“The photovoltaic system is permanently active and also generates energy when the vehicle is switched off,” Mercedes says. “In the future, this could be a highly effective solution for increased electric range and fewer charging stops.”
The layer of paste to be applied on EVs is significantly thinner than a human hair, yet its photovoltaic cells are packed full of energy. Covering the surface of a mid-size SUV with the paint could produce enough energy for up to 7,456 miles per year under ideal conditions, Mercedes says.
This does imply being in geographic locations with plenty of sun hours during the day.
But even with less-than-ideal sun hours, the energy yielded can make a significant difference to EV charging. Mercedes says the solar-paint charge could provide 100% of needed energy for an average daily drive of 32 miles in sun-drenched Los Angeles. In much less sunny conditions -- such as around Mercedes’ headquarters in Stuttgart, Germany -- it would still yield enough energy for 62% of the distance.
An added bonus for environmentally-conscious drivers: Unlike some solar panels, the solar paint contains no rare earth or silicon – only non-toxic, readily available raw materials. It’s also easy to recycle and considerably cheaper to produce than conventional solar modules, Mercedes says.
The likes of Aptera, Sono Motors, Lightyear, and Hyundai have also been researching how to best harness solar energy to power up EVs.
But that’s been mostly through solar panels yielding enough energy for small and light vehicles, such as Aptera’s three-wheel solar EV. Solar paint could bring solar charging for bigger vehicles, such as electric SUVs, Mercedes says.

Volkswagen’s affordable ID.2 EV remains on track

It’s no secret that Volkswagen has been facing a huge slump in sales in Europe and China, forcing it to close plants in Germany.

But unlike other European automakers who have stuck to producing high-end electric vehicles (EVs), the German automaker keeps on reaffirming its commitment to bringing affordable EVs to market, including in the U.S.
