    With its new space centre, NATO seeks the ultimate high ground

    Murray Brewster It's not the Space Force you may have heard about. Still, NATO's newly announced space centre boldly takes the seven-decade-old institution where no international military alliance has gone before. Most of its leading members and adversaries have sought individual advantage in the final frontier over the decades. And while the European Space Agency is a collective body, its civilian mission and its politics are inarguably different from those of NATO. That difference was on display this week as NATO defence ministers, meeting online, put the final pieces in place for the new centre, which has been in the works for a couple of years. "The space environment has fundamentally changed in the last decade," said NATO Secretary-General Jens Stoltenberg. "Some nations, including Russia and China, are developing anti-satellite systems that could blind, disable or shoot down satellites and create dangerous debris in orbit." NATO "must increase our understanding of the challenges in space," he said. Unlike U.S. President Donald Trump's much-hyped plan to make the Space Force a separate branch of the U.S. military, the North Atlantic alliance has been careful to present its space centre not as a "war fighting" arm but as something purely defensive. A 1967 international treaty commits 110 countries, including the United States and Canada, to limiting their use of space to "peaceful purposes" alone and prohibits the basing of weapons of mass destruction (nuclear bombs, for instance) in orbit. It further prohibits the militarization of the moon and other celestial bodies. Stoltenberg has insisted that alliance activities will be in line with international law. The rising threat of war in space That's an important point for Paul Meyer, adjunct professor of international studies in international security at Simon Fraser University in B.C. He warned in a recent policy paper for the Canadian Global Affairs Institute that the "prospects for armed conflict in space appear more likely than they have been since the days of the Cold War." Meyer said world leaders should think hard about what role — if any — arms control could play in avoiding a war in space. "Diplomatic solutions are not being pursued, despite the fact that irresponsible state conduct in space can ruin it for everyone," he said Friday. NATO has no satellites or space infrastructure of its own — but many member nations do and Stoltenberg said the alliance will draw on their expertise in setting up the new centre. Almost all modern militaries rely on satellites. In any major conflict between NATO and either Russia or China, the orbital communication and navigation grid would be the first piece of infrastructure to be hit. Not only does NATO need satellites for surveillance, reconnaissance and communications, an increasing number of military operations are being targeted from space. A good example is the 2003 U.S. invasion of Iraq, during which 68 per cent of airstrikes employed smart bombs guided by lasers and satellites. Those "eyes in the sky" are also important for defence against ballistic missiles and (naturally) weather forecasting. Diplomacy and deterrence Dan Coats, the former U.S. director of national intelligence, warned Congress almost two years ago that China and Russia have trained and equipped their military space forces with new anti-satellite weapons. Those warnings have not been limited to the Trump administration. In the spring of 2019, Norway accused Russia of "harassing" communications systems and jamming Norwegian Armed Forces GPS signals. Last spring, the NATO space centre reported that Moscow had test-fired a satellite-killing missile. Frank Rose, a senior fellow at the Brookings Institution, said in a recent online policy analysis that outer space will need to be "mainstreamed" within NATO when it comes to planning and operations. He also argued that the alliance will need to find a way to "incorporate diplomacy into any eventual strategy." Meyer agreed and noted in his October 2020 policy paper that Canada is largely absent from any meaningful debate on the militarization of space. The Global Affairs website, he said, contains outdated material, is full of banal, non-specific references and is largely devoid of Canadian content. "Pity the Canadian citizen who wishes to understand where our country stands on this troubling issue of outer space security," Meyer wrote. It's not clear what sort of contribution Canada might make to the new NATO space centre. In a statement, Defence Minister Harjit Sajjan said it's important for Canada's allies to develop a strategy that "ensures a peaceful use of space while protecting ourselves. "Canada has been a leading voice in NATO about the importance of space for the Alliance and we remain committed to working with our Allies and partners to prevent space from becoming an arena of conflict." https://www.cbc.ca/news/politics/nato-space-command-space-militarization-stoltenberg-1.5775269

  • Typhoon’s 'Digital Stealth' Can Evolve To Meet Changing Threat

    Typhoon’s 'Digital Stealth' Can Evolve To Meet Changing Threat

    by Jon Lake Mark Hewer, Leonardo's v-p for the Integrated Mission Solutions Business Area, believes that the company's open/reprogrammable electronic warfare (EW) suite for the Typhoon represents what he calls “digital stealth.” This will confer a high degree of survivability, even in a threat environment whose lethality is growing exponentially, with the emergence of a plethora of high-end, software reprogrammable, multi-spectral threats, including surface-to-air missile systems. These threat systems are being updated more regularly and are frequently networked, allowing them to share intelligence of the air situation. EW systems are able to evolve to deal with this dynamic and rapidly changing threat, in a way that fifth-generation stealthy aircraft cannot. While stealth aircraft are hard to detect, they are not invisible, and counter-stealth technology is developing rapidly. Moreover, the skin, internal structure, and configuration of an aircraft cannot be easily altered. “You cannot easily modify a stealth platform to counter new high-end threats,” Hewer said. Typhoon's EW capabilities are provided by Leonardo's Praetorian Defensive Aids Sub-System (DASS), which incorporates an onboard podded ECM system and off-board ECM, with a towed radar decoy, as well as missile approach, laser, and radar warning systems and a flare and countermeasures dispensing system. These systems will soon be augmented by the new BriteCloud, an active, highly programmable Digital RF Memory (DRFM) decoy that will allow the Typhoon pilot to better counter the highest-end threats. BriteCloud will give a discriminatory capability that is not on any other platform, providing a world-leading expendable active decoy capability on the Typhoon that none of its rivals will have. The MoD's Desidermagazine has predicted that initial operational capability on Typhoon will be declared in late 2019. Arguably more important than the performance of the individual hardware elements within Typhoon's DASS is their ability to be reprogrammed. “What is really important for the high-end customer buying Typhoon is that their EW system is highly programmable,” Hewer said. “There's no point in directing your ECM if it is going to be ineffective against a threat because you're not exploiting its vulnerabilities.” The Typhoon's EW system is undergoing continuous evolution, with regular upgrades to the hardware and a spiral software development process, but the most important factor is getting the right threat intelligence or “mission data” into the system. This is used to interpret the information that the sensors receive, and drives the behavior of the EW system. Mission success will often depend on having the most up-to-date data set to ensure relevance to the environment. This makes the rapidity of the upgrade cycle of paramount importance. Leonardo believes that many customers want a sustainable sovereign mission data capability, and it can offer to provide this as a service or as a fully tailored sovereign solution. The company can help customers to set up a national EW database or an aircraft specific database and has a suite of software tools available to customers. While F-35 naturally incorporates advanced EW systems, there is still a very heavy reliance on the U.S. for mission support, with a relatively cumbersome mission data cycle. Hewer believes that Typhoon is “many years more mature in its operational use of programming for EW.” While Leonardo's emphasis is currently on highlighting its ability to produce robust and agile high-end sovereign mission data generation capabilities for customers, the company is already looking to the future. Greater automation and machine learning promise a solution to the increasing complexity of the threat environment, and the company is also looking at the potential for sharing information across platforms as well as the possibility of reprogramming an EW system in flight. https://www.ainonline.com/aviation-news/defense/2019-06-19/typhoons-digital-stealth-can-evolve-meet-changing-threat
