    Europe must take on its own defense responsibilities

    By: Ian Bond As they look at the state of their coronavirus-hit economies and U.S. President Donald Trump's poor standing in opinion polls, many European leaders may be tempted to put on hold any plans to meet NATO's target of spending 2 percent of gross domestic product on defense. But Europeans need to wake up. Trump is not a reliable ally, and the damage he has done to the trans-Atlantic partnership is likely to linger. Trump's hostility to NATO has been obvious since he called into question its Article 5 mutual defense guarantee during his last presidential campaign. We now know, according to former national security adviser John Bolton's tell-all memoir, that Trump was ready to pull the U.S. out of NATO at its 2018 summit. In recent weeks Trump announced without warning that the U.S. will withdraw 9,500 — more than one quarter — of the 34,500 troops it has stationed in Germany because the German government is not spending enough on defense. Then at a Washington press conference with Polish President Andrzej Duda, Trump said a large number of NATO countries were “delinquent” and declared that Europe was taking “tremendous advantage of the United States on trade.” Trump may not understand how NATO works or the value to the U.S. of having troops in Germany, but it is true that the U.S. carries a disproportionately large share of the financial burden of defending Europe. During his presidency, Barack Obama also accused Europe of being “complacent” about its own defense — though he was rather more diplomatic. Only a handful of European NATO members have met the alliance's target of spending 2 percent of GDP on defense over the past 20 years, while the U.S. has consistently exceeded it, spending 3.1-4.9 percent. But Europe's problem is not just the amount it spends on defense, but the inefficiency and ineffectiveness of its spending: Europeans get far too many systems and far too little military capability for their money. The European Commission's 2017 fact sheet on European defense reported that European Union member states operated 178 different major weapons systems; the U.S. had only 30. EU member states have 17 different types of main battle tank; the U.S. has one. This proliferation of weapons systems leads to high unit costs for short production runs, and a lack of interoperability. And European spending is not directed to ensuring that troops can fight when needed. The European members of NATO have almost 1.9 million active-duty troops, while the U.S. has 1.3 million and Russia about 900,000. But very few of the European forces can be deployed in a crisis. Politically and economically, this is a bad time to try to get European politicians to think seriously about increasing and rationalizing defense spending. The EU's economic forecast for spring 2020 foresees a contraction in real GDP of 7.4 percent this year, albeit followed by an increase of 6.1 percent in 2021. Some of Europe's biggest investors in defense are in NATO but not in the EU. The U.K. accounted for 16 percent of defense spending in Europe in 2019, according to the Stockholm International Peace Research Institute. But despite some early promise, Britain seems to have lost interest in any institutionalized cooperation with the EU on foreign and security policy. Relations between the EU and NATO member Turkey, which accounted for another 7 percent of European defense spending last year, have rarely been worse. Despite such difficulties, the fact that NATO and the EU are currently both reassessing the security environment presents an opportunity for a more joint approach. NATO is engaged in the #NATO2030 process, which Secretary General Jens Stoltenberg hopes will strengthen political consultation in the alliance. Meanwhile, by the end of 2020 the EU aims to complete a process to assess the threats it faces, which the bloc calls its “strategic compass.” These two efforts need to complement each other to produce a shared view of the threats to Europe, and the creation of a forum for political dialogue on security where European countries, regardless of whether they belong to both the EU and NATO, can discuss appropriate responses. Europe's ability to counter threats will depend on making its money go further by spending it efficiently, both nationally and multilaterally. The commission should do more to ensure that more defense procurement involves competitive tendering, rather than member states awarding contracts to national champions. But it should not try to shut defense firms from non-EU NATO countries out of the European market. The commission stands more chance of influencing the research and procurement decisions of member states if it has a substantial budget to dangle in front of them. It should keep pushing back against cuts proposed earlier in the year to the defense elements of the EU's next seven-year budget. And the commission needs to be more open to the participation of “friendly” countries in EU-funded programs. Joe Biden, a former U.S. vice president and a contender in the current presidential race, would be an easier president for Europeans to work with than Trump has been. But Biden's victory in November is not guaranteed. Moreover, the forces in U.S. society that propelled Trump to power in 2016 will still exist, and may return in 2024. Even if they would rather pretend that nothing is changing, the EU and as many non-EU, Europe-based NATO members as are willing to do so need to pay attention to Trump's message. And they need to start thinking about how to defend Europe and deter potential adversaries with reduced U.S. help.

    Marines 3-D print replacement parts for F-35, unmanned ground vehicle

    By: Daniel Cebul WASHINGTON ― A U.S. Marine Corps pilot has successfully flown an F-35B Lightning II with a 3-D printed part. The Marine Fighter Attack Squadron 121 used 3-D printing to replace a worn bumper on the landing gear of the fighter jet. Marine Corps Sgt Adrian Willis, deployed with Combat Logistic Battalion 31, 31st Marine Expedition Unit, used the 3-D printer as part of a process otherwise known as additive manufacturing. Without a 3-D printing capability, the entire door assembly would have needed to be replaced, a more expensive and more time-consuming repair. Rather than waiting weeks for a replacement the bumper was printed, approved and installed within a few days. The repair demonstrates the value that additive manufacturing technology brings to forward-deployed units. “I think 3-D printing is definitely the future ― it's absolutely the direction the Marine Corps needs to be going,” Willis said. “As a commander, my most important commodity is time,” according to Marine Corps Lt. Col. Richard Rusnok, the squadron's commanding officer. “Although our supply personnel and logisticians do an outstanding job getting us parts, being able to rapidly make our own parts is a huge advantage.” Building off the achievement with the F-35 part, the MEU's explosive ordnance disposal team requested a modification part to function as a lens cap for a camera on an iRobot 310 small unmanned ground vehicle. Such a part did not exist at the time, but Willis and the 3-D printing team designed and produced the part, which is currently operational and protecting the robot's lens. https://www.defensenews.com/industry/techwatch/2018/04/25/marines-3-d-print-replacement-parts-for-f-35-unmanned-ground-vehicle/

    Here’s what the Space Development Agency wants from its first 10 satellites

    Nathan Strout The Space Development Agency is seeking proposals for its first batch of satellites, which will make up its initial transport layer — an on-orbit mesh network that will connect space-based sensors with terrestrial shooters. According to the May 1 solicitation, SDA is looking to award two contracts to build a total of 20 small satellites, which will comprise Tranche 0 of the National Security Space Architecture, a proliferated, low-Earth orbit constellation that will fulfill a multitude of military needs, including tracking hypersonic weapons; providing alternative position, navigation and timing data; delivering beyond-line-of-sight targeting; and more. Ultimately, the agency envisions a constellation made up of hundreds of interconnected satellites. Ten of those Tranche 0 satellites will form the agency's initial transport layer. The spiral development approach The agency is taking a spiral development approach to its National Security Space Architecture. Tranche 0 will be a testing and training segment that will demonstrate the integration of the architecture with other war-fighting efforts and inform future SDA developments. Tranche 0 is anticipated to be on orbit in the fourth quarter of fiscal 2022, with the SDA adding new tranches of satellites every two years, increasing the constellation's size and capabilities. Launch services will be acquired through the Orbital Services Program 4 contract or follow-on contracts. The philosophy behind the spiral approach is that the two-year cycles allow the agency to rapidly put new capabilities on orbit in response to evolving threats. Instead of waiting years for the perfect satellite system, the agency wants to push technologies that are currently ready into orbit as soon as possible, giving war fighters increased capabilities in the near term. With Tranche 0, the SDA wants to achieve periodic, regional, low-latency data connectivity. With Tranche 1, which will add 150 satellites to the constellation, the agency plans to provide persistent regional connectivity. Building a mesh network The National Security Space Architecture will be made up of several layers serving different functions. Tranche 0 will establish the transport layer, a space-based mesh network that will be able to pass data from one satellite to the next. The mesh network will operate as part of the Integrated Broadcast System, the Defense Department's standard network for transmitting tactical and strategic intelligence and targeting data. The key technology that will enable the transport layer are optical inter-satellite cross links, providing approximately 1 Gbps connections between the satellites. Each Transport Layer satellite will have four such cross links — forward, behind, right and left — which will allow them to pass data on to the nearest or next-nearest transport layer satellite operating in the same orbital plane. The satellites will also be capable of cross-plane cross links, meaning they will be able to connect to non-transport layer satellites operating above or below them. Assuming that they also have optical inter-satellite cross links, these non-transport layer satellites would then be able to pass data through the transport layer's mesh network to another satellite or even to a terrestrial shooter. For example, it could work like this: A space-based sensor collects imagery that it wants to pass to a ground-based system, but it is not within range of any ground station. No problem. The sensor would pass on that imagery to a transport layer satellite via an cross-plane optical cross link. The data would then bounce from transport layer satellite to transport layer satellite until it arrives above its destination, where it would then be downlinked to an optical ground terminal or distributed to the appropriate weapons system via the Link 16 tactical data network. In theory, this would allow shooters to receive space-based sensor data in near-real time. Since the SDA plans to continue building on the transport layer in subsequent tranches across multiple vendors, the optical inter-satellite cross links will need to be designed with interoperability in mind. The SDA also wants radio frequency cross links as a backup to the optical cross links. Tranche 0 will include 10 transport layer satellites — three of which will include Link 16 payloads. During an April industry day, SDA Director Derek Tournear said this initial, space-based mesh network will form the space network component to the Defense Department's Joint All-Domain Command and Control enterprise, or JADC2. “The transport layer, which is what the draft [request for proposals] and the industry day was talking about today, is going to be the unifying effort across the department. That is going to be what we use for low-latency [communications] to be able to pull these networks together, and that, in essence, is going to be the main unifying truss for the JADC2 and that effort moving forward. That is going to be the space network that is utilized for that,” Tournear explained. The agency has six goals for its Tranche 0 transport layer: Demonstrate low-latency data transport to the war fighter over the optical cross link mesh network. Demonstrate the ability to deliver data from an external, space-based sensor to the war fighter via the transport layer. Demonstrate a limited battle management C3 functionality. Transfer Integrated Broadcast System data across the mesh network to the war fighter. Store, relay and transmit Link 16 data over the network in near real time. Operate a common timing reference independent of GPS. According to the request for proposals, the SDA plans to award a contract Aug 10, with delivery expected by July 31, 2022. Responses to the solicitation are due June 1. https://www.c4isrnet.com/battlefield-tech/space/2020/05/05/heres-what-the-space-development-agency-wants-from-its-first-10-satellites/
