Marines increase ways to detect and kill air threats, from hobby drones to cruise missiles

By:

As Marine units face evolving drone threats from terrorist organizations and at the same time shore up their air defenses against near-peer air attacks, a few key pieces of gear in the most recent defense bill could vastly strengthen overhead protection.

Until recently, Marines tasked with taking down drones or short-range missiles had to link into a vast array of detection devices and then perform a practically 20th century task to take them out.

Essentially, a Marine with binoculars scans the air for drones while another Marine zeroes in with a Stinger missile ― first fielded in the 1980s but upgraded since ― to shoot down what is often a few hundred dollars' worth of a patched together, weaponized or surveillance-type commercial drone.

But a review of the past five years of Marine Corps budget requests and approvals for two systems, the Ground Based Air Defense-Transformation, or GBAD, and the Ground/Air Task-Oriented Radar, or G/ATOR, have more than doubled in the past five years and are projected to maintain or increase from now until 2022, when a GBAD with a laser component is expected to field.

Beginning as far back as 2013, the Marines have been purchasing the G/ATOR, an advanced radar system that executes the function of a combined five legacy systems.

    ICAO Council endorses new Global Aviation Security Plan

    ​The 36-State ICAO Council. In endorsing the very first Global Aviation Security Plan today to improve international coordination, reponse, and planning relating to threats to civil aviation passengers, aircraft and facilities, the Council encouraged the ICAO Secretariat to continue refining and improving it on the basis of close continued cooperation with States and security stakeholders globally, and with due attention to all applicable implementation assistance and capacity building requirements in ICAO's Regions. ​ Montréal, 15 November 2017 – The ICAO Council took an historic step in endorsing the very first Global Aviation Security Plan to improve international coordination, response, and planning to counter threats to civil aviation passengers, cargo, aircraft and facilities. “This new strategic document will assist ICAO Member States in their aviation security coordination with other States and applicable security agencies, as well as helping to nurture security cultures and capabilities, place greater focus on the role of new technologies and innovations, and refine related frameworks for oversight and quality assurance,” affirmed ICAO Council President Dr. Olumuyiwa Benard Aliu. A set of indicators and target dates have also been established, and all associated targets and outcomes will be regularly reviewed and adjusted, taking into account all new and emerging aviation security threats. “The Council has encouraged the ICAO Secretariat to continue refining and improving this critical living document, on the basis of close continued cooperation with States and security stakeholders globally, and with due attention to all applicable implementation assistance and capacity building requirements in ICAO's Regions,” Dr. Aliu further commented. Subsequent to its first review of the new Global Aviation Security Plan in June 2017, the Council authorized its transmission to ICAO Member States and international organizations for comment. Ninety-six percent of those replies indicated agreement with its scope and purpose, as well as the related strategies and global targets, which will continue to be refined. “The ICAO Secretariat has developed this strategic document on an accelerated basis to answer the call of ICAO's Council and Member States and the respective commitments and actions of national governments will now be essential to its overall impact and value,” commented ICAO Secretary General Dr. Fang Liu. “This new Global Aviation Security Plan will now take its place alongside ICAO's existing Global Plans for aviation safety and system-wide capacity and efficiency, and importantly it directly responds to various resolutions and expectations regarding aviation security and terrorism which have been expressed to ICAO by the United Nations Security Council.” The ICAO Global Aviation Security Plan calls for action at the global, regional and national levels by States, industry and other stakeholders in raising the level of implementation of Annex 17 to the Convention on International Civil Aviation – Security. Secretary General Liu further confirmed that a roadmap outlining 94 tasks, accompanying 32 actions under five key priority outcomes, will be central to the new Global Plan's roll out. These lay the groundwork for objectives over the next three years until the 40th Session of the ICAO Assembly in 2019. In line with its contribution to the Global Counter-terrorism Strategy of the United Nations, ICAO will continue to coordinate with the Security Council and its various committees on all priorities relevant to aviation and border security, and bring together the private and public sector partners who help ensure our network remains at the dependable service of societies and economies. https://www.icao.int/Newsroom/Pages/FR/ICAO-Council-endorses-new-Global-Aviation-Security-Plan.aspx

    Trump administration prepares to leave Open Skies Treaty

    By: Aaron Mehta and Joe Gould WASHINGTON — The Trump administration has made a final decision to withdraw from the Open Skies Treaty, sources confirmed to Defense News on Thursday. The news was confirmed by U.S. President Donald Trump midday, followed by a formal announcement by Secretary of State Mike Pompeo that the administration will make a formal notification on Friday, kicking off a six-month clock before a formal exit occurs. “We may, however, reconsider our withdrawal should Russia return to full compliance with the Treaty,” Pompeo said in a statement. What “full compliance” means, however, is unclear. Chris Ford, assistant secretary of state for international security and nonproliferation, told reporters there are “many variables” as to what that would entail, particularly as a number of American complaints about Russian activities involve behaviors that, Ford acknowledged, are “not in fact violations of the treaty.” As an example of the latter, Ford pointed to restrictions on flights over Kaliningrad. Russia has in the past restricted the length of flights over the city, which is not a direct violation but contradicts the confidence-building nature of the agreement, Ford said. That Russia will sometimes loosen those restrictions, such as earlier this year for an Open Skies flyover by Estonian, Lithuanian and American observers, is proof that the Kremlin “clearly regards its Open Skies legal obligations as something akin more to guidelines, or options, for them,” he argued. “It's the combination of all those things that has led to this decision. And so were Russia to return to compliance, we would have to presumably make that decision at the time about what to do with it, do in response to that, on the basis of the circumstances that have changed at that time,” Ford said. “Just as our decision now has many variables, we have to sort of see what the net impact of Russian behavior at that time in the world is. But that's a conversation we would very much like to have, if Russia would give the world the opportunity to see that happen.” In a statement released online, the Russian Ministry of Foreign Affairs called the move “very regrettable" and hit at the Trump administration's “general policy” of going after arms control agreements. International discussions The administration Thursday morning began informing the other 34 members in the agreement, which allows mutual reconnaissance flights over the member nations, including Russia. An emergency meeting of NATO members is scheduled for Friday in Brussels, per multiple reports. The move, first reported Thursday by The New York Times, was not a surprise, as administration officials signaled to European allies toward the end of last year that unless major changes were made to the overflight agreement, the U.S. would consider withdrawing. However, there had been little movement in the months since, giving advocates hope that a decision to exit the treaty had not been finalized. “It was pretty clear from meetings that it was basically a done deal and it was just a matter of when,” one European source said. Allies generally argue the treaty is a valuable channel for transparency and dialogue between Russia and the United States, the world's top two nuclear superpowers. Critics of the treaty have argued that the U.S. gets better intelligence from satellite systems and that the funding to replace the aging OC-135 aircraft can be spent elsewhere. A second European source acknowledged that Russia has not always complied with the treaty, but said there was a sense that those issues could be resolved. The source predicted that those NATO members who are also part of the treaty will remain, but was unclear what Russia will do next. “If you're Russia, you can stay in and take the moral high ground, say, ‘We still honor international treaties, even if America doesn't,' or you can say the treaty is diminished beyond usefulness and you pull out. I don't know which they'll do, but neither is good for NATO," the source said. The source added that while it is true the U.S. gets its best intelligence from its satellites as opposed to OC-135 flights, focusing entirely on that is “selfish” because “a lot of NATO allies rely on Open Skies for visibility into what goes on in Russia.” The Pentagon released a statement late on Thursday, saying “The United States has been in close communication with our Allies and partners regarding our review of the Treaty and we will explore options to provide additional imagery products to Allies to mitigate any gaps that may result from this withdrawal.” Key Democrats and arms control advocates quickly denounced the administration's withdrawal plans as dangerous and destabilizing to America's relationships with allies, with former CIA director Michael Hayden, a frequent Trump critic, decrying the move as “insane.” Conservative voices applauded the move as Trump standing up to Russia's violations of the treaty. Sen. Tom Cotton, R-Ark., expressed his belief the funding that would have gone into repairing the OC-135 should now go toward broader nuclear modernization. House Armed Services Committee Chairman Adam Smith, D-Wash., and House Strategic Forces Subcommittee Chairman Jim Cooper, D-Tenn., blasted the administration for defying a requirement in the 2020 defense policy law that Trump first give Congress 120 days' notice. Multiple communications with Congress on the issue had “gone unanswered,” they said. “The Administration's decision to withdraw the United States from the Open Skies Treaty is a slap in the face to our allies in Europe, leaves our deployed forces in the region at risk, and is in blatant violation of the law,” they said in a joint statement. “This decision weakens our national security interests, isolates the United States since the Treaty will continue without us, and abandons a useful tool to hold Russia accountable." When signing the defense policy legislation into law, Trump indicated he didn't consider himself bound by the requirement, citing his executive powers. “I reiterate the longstanding understanding of the executive branch that these types of provisions encompass only actions for which such advance certification or notification is feasible and consistent with the President's exclusive constitutional authorities as Commander in Chief and as the sole representative of the Nation in foreign affairs," the president's Dec. 20 signing statement read. Throughout its term, the Trump administration has been skeptical of arms control agreements. The U.S. and Russia walked away from the 1987 Intermediate-Range Nuclear Forces Treaty last August, and officials have expressed skepticism about renewing the New START nuclear agreement with Russia, which expires in 2021. https://www.defensenews.com/global/europe/2020/05/21/trump-admin-to-withdraw-from-open-skies-treaty/
