Here’s a look at the Arctic drones that can patrol Greenland’s ice sheet, track Russian subs for Trump

They’re a lot better than dog sleds.

The best new way to protect Greenland and answer President Trump’s demand for security improvements is using unmanned, winterized drones — heralded as a new leap forward to safeguard the vital territory and head off intrusions by Russia or China.

“They’re maturing, they’re versatile and they provide critical capabilities that can’t necessarily be substituted by human presence,” said Skip Davis, a retired US Army general with the Center for European Policy Analysis who co-authored a new report on drone capabilities in the frigid high north.

Air drones, if modified for the harsh Arctic terrain in Greenland, can sweep the landscape and provide “domain awareness” while autonomous subs track undersea activity.

“The Arctic is a very hostile environment to humans, and that is quite a challenge, because I would say that the first main challenge in Arctic military operations is how to survive the weather conditions in order to even get to combat,” said Minna Ålander, a fellow at CEP and analyst with the Stockholm Centre for Eastern European Studies.

“So there is a chance that you will die from natural causes, basically, if you’re not very well prepared.”

But the tech faces its own challenges.

Batteries degrade quickly in the high north, engines can freeze up, and it’s harder to hide an electronic signature from adversaries in the desolate landscape, security experts said.

“Before, a platoon can cover on skis, maybe if you squeeze them, 20 miles a night,” said Jan Kallberg of the Army Cyber Institute at West Point. “Through Lapland terrain [above the Arctic Circle in Europe] — here you don’t need to do it. You can send a drone to answer the intelligence questions.”

Frigid temperatures that shorten battery life, days without sun, and a lack of electronic infrastructure that might conceal drone operation are all factors that the technology must contend with U.S. Marine Corps Forces, Europe and Africa

Security experts are also pressing for the US and allies to find ways to better monitor Russian submarine activity in coastal areas of Norway as well as Greenland. That can involve undersea drones as well as sensors.

But the devices can be fragile, Kallberg said.

“It’s important to understand … about material, plastic and so forth, [it] gets brittle in the cold weather,” he said.

“War is a really practical thing. It’s very easy in the Beltway to see it as an intellectual sport, but it’s like plowing or carpentry,” he added. “So to maintain these repair, keep them functional over time, in an area with absolutely no support infrastructure, I find is the one of the largest challenges.”

Trump told The Post Friday in an exclusive Oval Office interview that the US will have sovereignty over the land where its military bases are sited in Greenland.

The US already maintains a Space Force base in Greenland under a 1951 agreement with Denmark that established an American military presence in the country.

Trump has previously mocked Greenland’s own security forces as “two dog sleds,” as he demanded Denmark and NATO up their games.
