The US Navy's Arctic muscles have atrophied over the years, so the service is working to relearn how to operate in this increasingly competitive space.
One way the Navy is doing that is by working with US allies and partners with the necessary knowledge and skills, picking their brains on how best to operate in this unforgiving environment.
Lt. Samuel Brinson, a US Navy surface warfare officer who took part in an exchange program aboard the Canadian frigate HMCS Ville de Quebec as it conducted Arctic operations, recently talked to Insider about his experiences.
Although he declined to say exactly where he went, Brinson said that he "didn't know anyone who had been as far north" as he traveled on his Arctic mission.
The US Navy's 2nd Fleet was reactivated last summer to defend US interests in the North Atlantic and Arctic waterways, as great power rivals like Russia and even China are becoming increasingly active in these spaces.
But there's a learning curve.
"2nd Fleet is a newly-established fleet, and we just haven't been operating in the Arctic as a navy much recently," Brinson told Insider.

"We need to get up there. We need to practice operating. We need to practice operating with our allies. We need to get up there and experience it for ourselves as much as possible."
That's exactly what he did. He went on a one-month fact-finding mission in the Arctic.
Brinson, who had previously deployed to the 5th and 6th Fleet areas of operations (Mediterranean Sea, Red Sea, Indian Ocean and Persian Gulf), was approached by 2nd Fleet for this opportunity, which involved reporting on how the Canadian navy carries out its activities in the Arctic effectively.
"The most striking difference [between the Arctic and other deployment locations] is how remote it is," he explained to Insider. "There are just not many towns. You go forever without seeing other ships. You go forever without seeing other establishments. The distance is a lot further between the places we were operating than it looks on a map."
From an operations perspective, that makes logistics a bit more difficult. "The biggest challenge for going into the Arctic is logistics," Brinson said.
"You have to have a plan where you are going and really think about where you are going to get fuel, where you are going to get food, and if you need to send people or get people from the ship, how and where you are going to do that. Everything is pretty far apart."
"You don't have a lot of refueling points, resupply stations," he added. "When you get up into the Arctic, there is not really anything there, and if someone had to come get you, like if they had to send tugs to come get us, it was going to take days, like lots of days."
The emptiness of the Arctic isn't just a problem from a resupply standpoint. It also creates navigational problems.
"Because it's less developed up there, it's also been less charted," Brinson told Insider. "We spent a lot of time switching between electronic charts, paper charts, you know, Canadian charts, Norwegian charts, etc. to navigate around where we were going. You have to use whichever chart was most complete and most up to date."
"There's a lot of headway that could be made on that in the future," he added. "The more we operate up there, the more we know that, but before we send ships in to some of these places, we probably need to just survey it first."

There's also frigid temperatures and ice to worry about.
Brinson, a native of Winston-Salem, North Carolina, was in the Arctic in August, a warmer period when the daytime highs were in the low 30s. "It was cold to me, but [the Canadians] all thought I was being silly," he said.
In the spring, fall, or winter, the temperatures are much lower, and there is a risk of getting iced in while at port. "Right now, you pretty much only want to be up there June, July, August, and then as it starts getting into September, it starts getting too cold," Brinson told Insider.
Even though the temperatures were higher when Brinson was there, ice was still a bit of problem. "There is enough around that you need to be extra careful, especially if it's nighttime or foggy. There were icebergs that were bigger than the ship," he said.
"If you were to hit something like that, it's a huge problem," Brinson added, recalling that he saw a polar bear roaming about on one of the icebergs with plenty of room to move around.

From the Canadians, Brinson learned how to deal with cold temperatures and ice, how to keep your water supply from freezing, which side to pass an iceberg on if there are pieces coming off it, and how to sail through an ice flow, among other things.
"Working with partners like Canada is key because they've never stopped operating up there," he said. "They know things like that."
Brinson told Insider that the US Navy has fallen behind and lost a step when it comes to Arctic operations. "What we need to do is just get back to doing it," he said. "We need to start getting the level of knowledge back."
