The U.S. Defense Department relies on a mixture of military and commercial satellites to connect its war fighters all over the world. And while users can complain that terminals are too bulky or that they should have the roaming capability exhibited in commercial cellphone technology, the system largely works.
But that's not the case in the Arctic.
“Very simple things become hard when you're in the Arctic, not the least of which is communication. When you are above about 65 degrees north, satellite communication starts to diminish, and above about 70 degrees north it becomes extremely limited except for some of our more exquisite capability — submarines, for example,” said U.S. Northern Command spokesman Maj. Mark Lazane.
The U.S. Space Force's primary communications satellite system, Wideband Global SATCOM, is designed to provide connectivity between 70 degrees north and 65 degrees south — basically to the edge of the polar region.
The Space Force also operates two Enhanced Polar System satellites — the Arctic complement to the Advanced Extremely High Frequency constellation. EPS satellites provide highly secure, anti-jamming signals, and like its counterpart, EPS is built for high-priority military communications, like that used with submarines.
And while elsewhere in the world the military supplements its purpose-built systems with commercial communications satellites, that option is limited in the Arctic. After all, commercial satellites providing coverage of other areas aren't solely serving the military, and the services rely on commercial consumers to offset the costs of designing, building, launching and maintaining a satellite. But there's far less commercial demand for satellite communications in the Arctic than in more populated areas, and commercial satellite coverage reflects that.
That leaves U.S. Northern Command with a significant gap in the connections available to its war fighters and platforms.
“Connection capabilities [in the Arctic] are limited and lack resiliency. We're challenged in areas from basic point-to-point connections to communication with our distributed sensors,” Lazane said. “Having a reliable broadband communications capability for Arctic operations is the top unfunded priority of USNORTHCOM. With the increase of great power competition in the Arctic, there is a need for additional communications capability and capacity.”
But the command thinks it's found a solution in the form of new, proliferated commercial constellations. Private companies OneWeb and SpaceX have launched hundreds of satellites into low-Earth orbit in an effort to provide competitive broadband to users all around the world.
USNORTHCOM is asking Congress for $130 million to explore OneWeb's and SpaceX's capabilities in order to provide reliable and potentially cost-effective connectivity to Arctic platforms, installations and war fighters.
“Leveraging emerging proliferated low-Earth orbit commercial SATCOM providers in the Arctic enables the United States (and our allies) the opportunity to scale communications capability and capacity quickly in a cost-effective manner,” Lazane said. “The unique capabilities provided by PLEO [proliferated low-Earth orbit] commercial SATCOM providers in the Arctic enables access to high-bandwidth, low-latency communications capability and capacity.”
In a Feb.11 letter to Congress, USNORTHCOM Commander Gen. Terrence O'Shaughnessy said that funding for this effort was his No. 1 unfunded priority. If approved, the $130 million in funding will be used for polar communications experiments as well as the fielding of prototype terminals that can connect to commercial PLEO constellations.
If those experiments prove successful, USNORTHCOM would need another $110 million in fiscal 2022 for full coverage.
SpaceX has stated that its Starlink constellation will begin offering broadband services this year, and USNORTHCOM is hopeful that could enable early Arctic capability by the end of the year.

Tony Osborne Ninety percent of Britain's front-line combat aircraft are crewed, but British Defense Secretary Ben Wallace says he expects a “major reversal” of these proportions by 2040. Wallace's speech at the opening of a virtual Farnborough Airshow on July 20—a message reminiscent of the late Duncan Sandys' 1957 defense white paper that declared the manned fighter redundant and guided and ballistic missiles to be the future of Britain's defense—may hint at a radically altered Royal Air Force (RAF) with heavy fielding of swarming UAVs and other additive capabilities such as “loyal wingmen” dominating fleets. But Wallace's comments also touched on the trajectory for the UK-led Tempest Future Combat Air System (FCAS), which is targeted to begin to replace the UK's fleet of Eurofighter Typhoons from 2035. Air Chief Marshal Mike Wigston, chief of the Air Staff, said at the RAF's annual air power conference on July 15 that he intended any FCAS to be optionally manned. Sandys' defense plan sent reverberations through the UK aerospace industry, but the vision for the Tempest calls for a similar fundamental revolution. Saab spending £50 million on UK FCAS hub Technologies are being matured to support year-end business case submission BAE Systems says its factory of the future will subsume the need for heavy, fixed and long-lead tooling—halving production time compared with previous programs. And industry is looking to new players for cybersecurity technology from the banking world and materials technology from the automotive sector, companies from outside the typical defense industrial base. Two years since the announcement of Team Tempest—the industry consortium of BAE Systems, Leonardo, MBDA, Rolls-Royce and the British government's Combat Air Strategy that coalesced at the 2018 Farnborough Airshow—the group is growing for the first time, with the inclusion of Bombardier UK, Collins Aerospace, GE UK, GKN, Martin-Baker, Qinetiq and Thales UK. The additions to the team come in the form of a first wave of industrial agreements, with BAE hinting that more industrial partners will follow. Of the new partners, Collins announced it had been contracted by BAE to provide advanced actuation capabilities. Sweden's Saab announced also on July 20 that it is investing £50 million ($58 million) into the creation of an FCAS center in the UK. The facility will serve as a hub for the company's participation in the FCAS and represent Stockholm's first tentative steps into the venture. Saab does not name the Tempest specifically, with CEO Micael Johansson hinting that Sweden's involvement is focused more on the technology rather than the future platform. “Saab's FCAS strategy ensures that the technology is in place to support a long-term future air capability and also to support continuous upgrades of Gripen E for decades to come,” Johansson said. While the international partnership model for the Tempest has yet to be finalized, British officials have suggested that the partnerships could be agile and scalable. In other words, allowing nations to “partner in a way that suits them,” Richard Berthon, the UK Defense Ministry's Combat Air acquisition program director, previously told Aviation Week (AW&ST July 13-26, p. 52). Johannsson said nations looking to refresh their fleets with the current generation of fighters, like the Gripen or Typhoon, should not be concerned about the push to deliver the Tempest during the 2030s. “A strong joint partnership around a future combat air system will also guarantee Gripen and Eurofighter access to new technologies,” Johannsson said. Existing customers, he said, should see the FCAS as a “seal of approval as we safeguard continuous fighter development.” Until now, the work between the national partners had been on a bilateral basis. The aim was “to define our common objectives,” BAE Systems CEO Charles Woodburn says. But this work has now extended into trilateral studies that include “assessing how we can start to realize the huge potential for collaboration across our three nations,” Woodburn says. Although the talks are now trilateral in nature, the UK says it is still keen to see more international partners “join our flightpath to discovery,” Wallace adds. Industry is already beginning to think trilaterally, with GKN Aerospace in Sweden confirming it will work with Rolls-Royce in the UK and Avio Aero in Italy on feasibility studies for a future fighter jet engine. GKN states it was contracted in the first quarter of 2020 by Sweden's defense materiel agency, FMV, to conduct a study in collaboration with Rolls-Royce. Few details have emerged on the 60 technology demonstration programs currently being developed and matured by Team Tempest in support of the UK Future Combat Air System Technology Initiative (FCAS TI). Michael Christie, BAE's head of Future Combat Air Systems, says work on maturing the technologies ready to support the business case submission to the British government at the end of this year has seen the partners “at least achieve or exceed” the maturity targets set, doing so “at great pace” and providing “fundamental evidence to the business case.” “Every one of these [60] projects will deliver a UK, European or world first,” says Cecil Buchanan, the RAF Rapid Capability Office's chief scientist. https://aviationweek.com/ad-week/trilateral-tempest-expands-industrial-base
