SpaceX could fill the US military’s Arctic communications gap by the end of this year
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.

Australia releases RFI for at least 16 special operations helicopters
By: Nigel Pittaway MELBOURNE, Australia — Australia's Defence Capability Acquisition and Sustainment Group issued a request for information for at least 16 special operations support helicopters. The helicopters will be acquired under Project Land 2097 Phase 4, which has not been formally approved by the Australian government but has been identified as a priority for future defense spending in the 2016 Defence White Paper. The proposed timeline calls for a request for tender in the fourth quarter of 2019, with the major delivery of equipment to follow in 2022. “The project is currently in the exploratory phase, collecting information and proposals to inform concepts for capability realisation,” according to the RFI's cover letter, authored by CASG's acting first assistant secretary of the helicopter division, Brigadier Jeremy King, and the head of land capability at Army Headquarters, Maj. Gen. Kath Toohey. “The project is considering a wide range of procurement options based around a light helicopter as the major system. The acquisition strategy is developmental and is subject to Government approval,” the letter read. According to the RFI, the requirement is for a proven commercial or military off-the-shelf light helicopter, which is already in service with other operators. Other requirements include optimization for use in dense urban environments, capable of rapid deployment by the Royal Australian Air Force's C-17A airlifters, and the ability to be fitted with simple and proven intelligence, surveillance and reconnaissance equipment and weapons. The helicopters are intended for use by the Australian Army's 6th Aviation Regiment, based at Holsworthy, south of Sydney, and will complement a squadron of larger NHI MRH-90 Taipan helicopters. The Taipans are replacing the 6th Aviation Regiment's existing Sikorsky S-70A-9 Black Hawk, beginning in January 2019. The RFI does not specify a desired size for the new helicopter, but four are required to be deployed aboard one C-17A. In an earlier update to the Army's major battlefield aviation programs, CASG's first assistant secretary of the helicopter systems division, Shane Fairweather, and Toohey discussed a helicopter in the four-ton class. The primary role of the new helicopter will be to provide an air assault capability by small teams of special forces, with secondary roles including ISR (using electro-optical sensors), fire support and general utility. The RFI calls for a helicopter that can be rapidly reconfigured between these roles. The main base for operations will be at Holsworthy, but the Australian Army is considering the establishment of a permanent detachment of helicopters — referred to in the RFI as the “independent detachment” — in a yet-to-be-decided location. Australia's Special Operations Command has two commando regiments based at Holsworthy and the Special Air Service Regiment based in Western Australia. The RFI calls for four helicopters to be maintained online at Holsworthy, in addition to the independent detachment (four aircraft) and two deployable elements, each of four helicopters. The number of helicopters to be acquired is not specified in the document, but respondents are asked to provide an assessment of how many will be needed to support 16 aircraft online at any given time. The forthcoming RFI was a major focus at the 2018 Land Forces exhibition, held in Adelaide in early September, with several major helicopter manufacturers declaring their intention to respond. Then-head of Airbus Group Australia Pacific Tony Fraser said the European manufacturer intends to offer its 3- to 7-ton H145M helicopter. “We will compete the H145M and we expect it to be a very strong competitor,” he said. Also speaking at Land Forces, Bell's business development director for Australia, Dan McQuestin, revealed that the company intends to bid the 2.5-ton Bell 407GT, an armed version of the popular 407GX civil helicopter. “It's COTS, it's already deployed in the field in the Middle East and maintained through a commercial supply chain,” he said. Boeing Defence & Security's vice president of global sales and marketing for Australia said he was keen to see what the Commonwealth's requirements would be, but the U.S. manufacturer saw its 1.6-ton AH-6i Little Bird as a candidate. “Based on our conversations, we think the AH-6i is a viable alternative for Land 2097 Phase 4,” he said. “We'll see what is in the RFI, but we certainly expect to bid.” Leonardo's helicopter division announced during the show that it will propose the AW109 Trekker helicopter. Other potential contenders include MD Helicopters with its MD530G helicopter, and Northstar Aviation with the 407MRH Lightning, a multirole helo based on the Bell 407. https://www.defensenews.com/industry/2018/10/02/australia-releases-rfi-for-at-least-16-special-operations-helicopters

Serbia looks to acquire Chinese drones and the technological know-how
By: Jaroslaw Adamowski WARSAW, Poland — Serbia's acting assistant defense minister has announced the ministry is negotiating with a number of Chinese drone manufacturers to acquire UAVs for the Serbian military. Nenad Miloradovic said Serbia aims to buy Chinese drones for its armed forces as well as the technology that will allow the country's defense industry to produce UAVs in the long term. "This package deal, under which we plan to purchase, but also produce reconnaissance drones for the Serbian military, should be implemented shortly," Miloradovic said, as reported by local daily Blic. The official said that Serbia is positioning itself as a military-neutral country, and its government aims to procure weapons and military gear for the country's armed forces from various suppliers. "We don't have ideological prejudices in what concerns buying weapons," Miloradovic said. In a sign of strengthened military cooperation with Russia, Serbia's government earlier this year approved the purchase of six Mil Mi-17 helicopters, complementing acquisitions of other aircraft and weapons from Moscow. In contrast, Serbia signed a deal in 2016 to buy nine H145M helicopters from Dutch-French company Airbus. The value of the planned UAV deal was not disclosed by the Serbian official. https://www.defensenews.com/unmanned/2018/09/20/serbia-looks-to-acquire-chinese-drones-and-the-technological-know-how
