WASHINGTON — The U.S. Army's tactical network program office expects to reap the full benefits of low-and medium-Earth orbit satellite constellations in the 2025-2027 time frame, the head of the office said Aug. 18.
Speaking on a webinar hosted by the Defense Advanced Research Projects Agency, Brig. Gen. Rob Collins, program executive officer at Program Executive Office Command, Control, Communications-Tactical, said the two constellations types offer “game-changing technologies” that will likely be fully mature and ready for soldier use in Capability Set ‘25 or ‘27, the two-year cycle of new network tools the service is fielding.
One of the connectivity benefits of the LEO and MEO constellations in the field, Collins said, is that they can allow for complex network functions and mission-support capabilities to remain in a safer place.
“We may be able to put those in an area in a more safe sanctuary and allow our war-fighting formations, our brigades and divisions to better focus on what their tactical mission is without having to concern themselves with the force protection of those areas,” the one-star general said at DARPA's virtual Electronic Resurgence Initiative Summit.
The Army is interested in LEO and MEO satellite constellations because they can provide significantly more bandwidth and reduced latency. “It's really all about having a resilient network architecture that takes advantage of all the layers that can be expeditionary,” Collins said.
LEO and MEO can also allow for smaller ground terminals, which will increase mobility for the soldier, he added.
PEO C3T is currently working on prototypes of new satellite capabilities in partnership with the Army's Combat Capabilities Development Command. PEO C3T's Project Manager Tactical Network division will run lab-based experimentation with new satellite terminals this summer to “exploit some of the commercial capabilities,” Collins said. The program office is also working with the CCDC's Space and Terrestrial Communications Directorate on creating multi-band satellite terminals.
5G technology will add an additional layer of network speed. Collins said the Army anticipates 5G technology has the “potential” to be incorporated into Capability Set '25. But he warned that the Army operates in unique environments with rough terrain and foliage that can affect communications, and can not always rely on towers and relay stations.
“I think one of the things we're going to have to do is how can we take and best employ some of this technology, how do we link it into our current environment and ensure that it's mobile,” Collins said. “And then probably, importantly, to make sure how do we secure some of the endpoints associated with the technology. I think that's really an area that we'll be reaching out to industry, academia and others to see how we best incorporate that.”

By: The Associated Press BEIJING — A study says Southeast Asian countries are cutting defense spending as a result of the economic crisis brought on by the coronavirus outbreak, potentially opening up room for China to further assert its claims in the region. Aristyo Rizka Darmawan, a maritime security expert at the University of Indonesia, writes that slashing defense spending is seen as a relatively easy way to cut costs when countries are facing pressure on their budgets. “Indonesia, for example, has announced it will slash its defense budget this year by nearly US$588 million. Thailand has likewise reduced its defense allocation by $555 million. Malaysia, Vietnam, and the Philippines all face similar pressure,” Darmawan wrote in the online journal of the Lowy Institute, an Australian think tank. “Less defense spending will invariably mean less patrols at sea.” China recently announced it will increase its defense spending by 6.6 percent in 2020, despite a major downturn in the country's economic growth due to the pandemic. The increase is the lowest in years, but will still allow China to expand its ability to enforce its territorial claims in the South China Sea and grow its military presence in the Western Pacific and Indian oceans. Another key priority is maintaining a credible threat against Taiwan, the self-governing island democracy that China considers its own territory, to be brought under its control by military force if necessary. China has maintained its presence in the South China Sea throughout the virus outbreak. Recent frictions include Chinese ships shadowing Malaysian mineral exploration operations and the sinking of a Vietnamese fishing boat by a Chinese maritime security vessel. However, China's foreign minister dismissed claims that the country is exploiting the coronavirus outbreak to expand its regional footprint, labeling such accusations as “sheer nonsense.” State Councilor and Foreign Minister Wang Yi told reporters at a news conference on Sunday that China is cooperating closely on anti-virus efforts with Southeast Asian countries, several of whom have overlapping territorial claims with China in the strategically vital waterway. While China has long been stepping up its presence in the region, Wang said other countries — likely meaning the United States and its allies — have been creating instability with military flights and sea patrols. “Their ill-intentioned and despicable moves are meant to sow discord between China and [Southeast Asian countries] and undermine the hard-won stability in the region,” Wang said. https://www.defensenews.com/global/asia-pacific/2020/05/26/downward-trend-southeast-asian-countries-cut-defense-spending/

NATO said on Monday it will increase targets for stockpiling ammunition as Kyiv is burning through shells much faster than Western countries can produce them and after a year of conflict in Ukraine has left allied stocks badly depleted.
