is Gen. Glen VanHerck, head of U.S. Northern Command and North American Aerospace Defense Command.

VanHerck told lawmakers during a hearing this spring on Capitol Hill that military efforts in the Arctic are meant to ensure the area remains “peaceful, stable and cooperative.” He noted that the United States is one of eight nations that in 1996 formed the Arctic Council. The other seven members are Canada, Denmark, Finland, Iceland, Norway, Russia and Sweden.

There are now concerns that as Russia becomes more isolated following its invasion of Ukraine, it could take a more aggressive posture in the Arctic. Russia’s eastern border is only 90 kilometers across the Bering Strait from the coast of Alaska.

VanHerck noted that 25 percent of Russia’s gross domestic product comes from oil, minerals and other natural resources extracted in the Arctic. “So they absolutely have a vested interest in the Arctic, and they also want to ensure that it is secure for their efforts.”

Over the past several years, Russia has revitalized a dozen or so military installations in the Arctic that had sat dormant after the Cold War, said VanHerck. “Not only are they placing defensive capabilities that they state are obviously for defensive purposes, they are putting offensive capabilities into the Arctic,” he said, including missiles that could strike North America.

Russia formed the Northern Fleet Joint Strategic Command in December 2014 to coordinate efforts in the Arctic. Since then, DoD said in its strategy document, Russia has gradually strengthened its presence by creating new Arctic units, refurbishing old airfields and infrastructure, and establishing military bases along its Arctic coastline.

Russia also has been working to establish a network of air defense and coastal missile systems, early warning radars and rescue centers, the DoD strategy said. In February 2021, Russia launched the Arktika-M satellite to monitor the climate and environment in the region.

The United States is also watching China’s moves in the Arctic. “China calls itself a near-Arctic nation and wants to be influential in the Arctic as well,” said VanHerck.

Concerning U.S. capabilities, “I would assess that we’re in the game plan development,” he told the House Armed Services Committee. “We’re not able to have the persistence that I need to compete day-to-day in the Arctic.”

Another looming concern for DoD is how climate change could impact U.S. military infrastructure in the Arctic. The issue was investigated recently by the department’s inspector general, who concluded in a report last month that DoD will need to invest billions of dollars to make military installations in the Arctic and sub-Arctic more resilient to climate change.

The IG evaluated Thule Air Base in Greenland and DoD’s five military bases in Alaska.

“Officials from all six installations identified current climate and energy challenges, such as cracked runways, sunken foundations, and multiple power outages,” said the IG report. At most of these installations, the “day-to-day focus was on reacting to immediate problems or reducing risk to existing hazards, rather than planning for future hazards.”

The report said some construction projects at Army, Air Force and Space Force installations are already being funded to support increased Arctic operations.

MORE SITUATIONAL AWARENESS
There is a huge need in the Arctic for reliable surveillance and communications systems because miscommunications could trigger unintended conflict, Lt. Gen. S. Clinton Hinote, deputy chief of staff for Air Force Futures, said at a Wilson Center panel discussion.

“Awareness about what is going on in the Arctic is a key part of preserving peace,” he said.

For example, in military wargames, the “avenues of approaches over the Arctic” for enemy missiles or bombers are a major concern. “The Arctic is the shortest route between our competitors and us.”

The U.S. Air Force has operated in the Arctic for decades, Hinote said. “But our use of the Arctic as a strategic buffer is eroding for all the reasons that have been
talked about, especially climate change, and especially with some of the activities that we see Russia and China engaging in.”

As the Arctic melts, “competition for resources and influence in the region will increase,” he said.

Hinote said the U.S. Air Force in recent years has intercepted and warned away a growing number of Russian military planes flying near the edge of Alaska’s restricted airspace. These security concerns “drove our focus on the Arctic and the release of a strategy.”

Wargames organized by the U.S. military and allies typically have focused on “countering great powers specifically in Europe and in the Asia Pacific,” Hinote said. “And one of the things that we felt like we did not understand as well was how that competition would spill over into the Arctic.”

Live military exercises like NATO’s Cold Response, NORAD’s Operation Noble Defender, and Northern Command’s Arctic Edge are helping the U.S. and allies “understand the nature of the competition,” he said. The submarine-focused Ice Exercise (ICEX) has been held since the 1960s, making it the longest-running Arctic exercise.

To bolster the U.S. posture in the Arctic, the Air Force is stationing 54 F-35 advanced fighter aircraft at Eielson Air Force Base, Alaska.

“Alaska is an incredibly well-positioned base of operations for defending the northern approaches to the United States, and this is why so many of the intercepts that happen when an adversary’s aircraft is coming from the north are done with assets that are stationed in Alaska,” Hinote said.

The Department of the Air Force’s Arctic strategy also recommends greater use of space assets to support military and homeland defense efforts.

“Space capabilities are tailor-made to support a region where there is sparse ground infrastructure,” Lt. Gen. William Liquori, deputy chief of space operations for strategy, plans and programs for the U.S. Space Force, said at the Wilson Center panel.

“The satellite command-and-control capabilities that we have at Thule, those are there because military operations are going to happen in the Arctic,” said Liquori. “And that means we’re going to need to have satellite coverage in the Arctic.”

To fill gaps in satellite communications coverage over the Arctic, the Air Force worked out a deal with the Norwegian Space Agency subsidiary Space Norway to launch two U.S. military communications payloads on Norwegian satellites. The payloads, developed by Northrop Grumman, will be integrated into the Arctic Satellite Broadband Mission satellites, projected to launch on a SpaceX rocket in 2023.

Any Arctic strategy has to consider the importance of the space domain, said Mir Sadat, a nonresident fellow at the Atlantic Council’s Scowcroft Center for Strategy and Security.

The United States is not doing enough to “prepare for the new frontier.” In contrast, Russia and China, by increasing their activities in the region, are positioning to one day take advantage of shorter sea lanes, Sadat said. A key goal for China and Russia is to “reach global markets or military targets faster and much more cheaply,” he said.

Satellites to watch what Russia and others are doing on the ground is another critical capability that the United States might need to expand, said Scott Herman, CEO of Cognitive Space.

The company participated in the recent Arctic Edge 2022 exercise as a military contractor, orchestrating collection opportunities across commercial satellite operators.

Today, many commercial remote-sensing constellations can’t support Arctic activities because they can’t reach those high latitudes, said Herman. But if the Arctic becomes a geopolitical flashpoint, “you may see some adjustments to some of the satellite constellation plans to make sure they’ve
got sufficient northern exposure.”

In its strategy, the Department of the Air Force said there is a need for “domain awareness through new technologies ranging from over the horizon radar to space assets.”

FEARS OF ‘MISCOMMUNICATION’
Michael Sfraga, chair and distinguished fellow of the Wilson Center’s Polar Institute, said an imminent war in the Arctic is unlikely.

“I think that’s a low probability,” said Sfraga, who is based in Alaska. But he believes the risk will increase as countries step up activities.

“The higher probability, unfortunately, is a miscommunication: An exercise gone wrong, a missile fired by mistake, Russian bombers are escorted out of our airspace and there’s a miscommunication between pilots,” he said.

Russia’s invasion of Ukraine now casts things in a different light, he added. “No one thought something like Ukraine would actually happen. If anybody would have told you 20 years ago that China would have built islands in the South China Sea and claimed that territory, I would have said that seems pretty far-fetched.” The lesson for the United States is to remain “vigilant and diligent.”

It’s well known that Russia derives a significant portion of its GDP from natural resource development in the Arctic, Sfraga said. It’s also continuing to expand its military presence and capabilities in the region. “China, which sometimes forgets that it’s not actually an Arctic state, is doing everything it can to establish its own influence in Arctic governance and economic development.”

“While there’s no imminent threat of conflict in the Arctic, the increasing activity and proximity of these aggressive powers requires the U.S. to maintain situational awareness and operational capacity,” he said.

The United States has to be better prepared to operate in the Arctic, Sfraga said, and noted that satellite-based services are sorely needed in the area.

“Satellite communications, imagery, all of those things are very important to our national and civil security, search and rescue,” he said. “There’s just limited capacity.”

“Presence equals influence,” he said. “Showing potential adversaries that you can actually conduct operations and protect your own interests in a landscape like the Arctic serves as a deterrent and is incredibly important.”

NASA to buy five additional Crew Dragon flights

WASHINGTON — NASA is planning to purchase five more Crew Dragon missions to the International Space Station from SpaceX, a move the agency says is needed to ensure long-term access to the station.

In a procurement notice published June 1, NASA announced its intent to issue a sole-source modification of its existing Commercial Crew Transportation Capabilities, or CCtCap, contract with SpaceX to add five missions to the station later this decade.

NASA said in the filing that it needed to add the missions to the contract for several reasons, including delays in the development and certification of Boeing’s CST-100 Starliner crew vehicle, projections of when the additional missions would be needed and “the technical challenges associated with establishing and maintaining” crew transportation systems capable of flying every six months.


The notice added that the additional missions “will ensure redundant and backup capabilities through 2030” for the ISS. The White House announced at the end of last year its intent to extend ISS operations through 2030, an extension supported other station partners except for Russia.

In a blog post published without fanfare by NASA late June 1, agency officials said the additional missions will ensure that they can bring Starliner into service without rushing it. “It’s critical we complete Starliner’s development without undue schedule pressure while working to position both Boeing and SpaceX for sustainable operations in the years ahead,” said Steve Stich, NASA commercial crew program manager.

“Boeing’s Orbital Flight Test-2 went very well and we hope to be able to certify the Starliner system in the near future,” said Phil McAlister, director of commercial space at NASA. “However, we will need additional missions from SpaceX to implement our strategy of having each commercial provider flying alternating missions once per year.”

The original CCtCap awards to Boeing and SpaceX in 2014 provided each company with six operational, or post-certification, missions. Boeing has yet to perform any post-certification missions, as Starliner is still in testing. SpaceX is currently on its fourth post-certification mission, Crew-4, which launched to the station in April.

NASA, anticipating that SpaceX would soon complete all six missions while Starliner was still in development, awarded SpaceX three additional mission in February for $776 million. The new modification, if it goes forward, would bring the total number of post-certification missions awarded to SpaceX to 14.

By the time SpaceX starts flying those additional missions, Boeing’s Starliner should be in service. NASA and Boeing officials said after the completing of the OFT-2 uncrewed test flight May 25 that they believed they would be able to proceed with a crewed test flight as soon as late this year. If that is successful, Starliner could begin post-certification missions as soon as the fall of 2023, after SpaceX’s Crew-6 mission slated to launch in the spring of 2023.

If that schedule holds, and NASA is able to alternate missions between the two companies, Boeing’s current contract would support missions launching through 2028. SpaceX’s extended contract would allow missions to 2030, with SpaceX returning to two missions a year after the conclusion of Boeing’s contract.

NASA said in the statement that the extension planned for SpaceX “does not preclude NASA from seeking additional contract modifications in the future for additional transportation services as needed.” In the case of Boeing, an extension would likely also require certification of a new launch vehicle, as its current Starliner missions are slated to fly on the Atlas 5, a vehicle that United Launch Alliance is no longer offering for sale and plans to retire, lik

NASA selects Axiom Space and Collins Aerospace for spacesuit contracts

Updated 7 p.m. Eastern with additional contract details.

WASHINGTON — NASA awarded contracts to Axiom Space and Collins Aerospace to provide spacesuits for International Space Station spacewalks and Artemis moonwalks, although neither the agency nor the winning companies offered many technical or financial details.

NASA announced June 1 it selected the two companies for Exploration Extravehicular Activity Services, or xEVAS, contracts to support the development of new spacesuits as well as purchasing spacesuit services. The companies will own the suits they develop and will effectively rent them to NASA for space station and Artemis missions, while also being able to offer the suits to other customers.


The goal, NASA officials said at a briefing about the awards, is to have lunar spacesuits ready for the Artemis 3 lunar landing mission, currently scheduled for no earlier than 2025. NASA will also conduct an “orderly transition” from existing, decades-old suits on the ISS to the new suits around the same time.

NASA earlier planned to develop suits internally though an effort known as the Exploration Extravehicular Mobility Unit, or xEMU, but shifted gears to a services model with competition, building on the accomplishments of commercial cargo and crew transportation. NASA is making xEMU data and other capabilities available to the companies to support their work.

“I really believe that all of that data is helping to reduce the risk and speed that transition process up to the contractor community,” said Lara Kearney, manager of the extravehicular activity and human surface mobility program at NASA’s Johnson Space Center. “We were at a great place to transition just because of how mature the xEMU was at the time.”

Axiom, which is working with a team of companies that includes David Clark Company, KBR and Paragon Space Development Corporation, intended to develop spacesuits to support its commercial space station plans.

“We have a number of customers who already would like to do a spacewalk,” explained Michael Suffredini, president and chief executive of Axiom, said at the briefing. “It’s fantastic to have a partnership where we can benefit from the years of experience that NASA has and all the work they’ve done to advance designs.”

Collins Aerospace, working with ILC Dover and Oceaneering, plans to make use of experience that includes development of the Apollo moonwalking suits and the spacesuits used today on ISS spacewalks.

“The goal is to take the foundations that NASA laid with the xEMU in partnership with industry and evolve that technology, and create a suit that is compatible with the entire spectrum of crew members,” said Dan Burbank, senior technical fellow at Collins.

Both Burbank, a former astronaut, and Suffredini, a former NASA ISS program manager, emphasized their commitment to meeting NASA’s extensive requirements for the suits, including being compatible with astronauts ranging in height from the 5th percentile woman to the 95th percentile man.

However, the companies provided few technical details about their suit designs, and NASA did not even have illustrations of the winning designs to show, electing instead to release an illustration of two moonwalking astronauts wearing suits not necessarily associated with either company. Collins did later release several illustrations of its proposed suit as well as images of that design being testing in a lab.

The total value of the xEVAS contracts is $3.5 billion through 2034, a figure that assumes all task orders are exercised. NASA officials at the briefing declined to break out that total between the two companies, stating that information will instead be in the source selection statement for the procurement, expected to be
