Growing threat at high altitude: innovation to fight drones

Over the past ten years, the growing availability of Unmanned Aerial Vehicles (UAV), commonly known as drones, has been a blessing for video enthusiasts and other tech addicts. But it also created a headache for safety authorities. To respond to this flourishing market, countermeasures are being developed in parallel, and represent a full-fledged business today.

Very early after their appearance on the market, drones invited themselves on the battlefield. In 2014, the Islamic state was already using versions (Phantom 3 or 4) for reconnaissance. Then came the suicide drones, fitted with makeshift grenades.

Conventional armies are also increasingly relying on them. If the United States used to have a quasi-monopoly on offensive UAVs at the beginning of the 21st century, countries such as China, Russia, and even Iran are constantly trying to fill the gap.

In 2019, a wave of Iranian-made Qasef drones operated by the Houthi rebels took Saudi Arabia by surprise. Despite the presence of modern anti-aircraft missile systems such as the Patriot, the refineries of Abqaiq and Khurais, eastern Saudi Arabia, were heavily damaged, putting half of the country's oil production to a halt.

Even in times of peace, UAVs can constitute a threat. In January 2019, drones caused a panic at London Gatwick Airport (LGW), United Kingdom, in the days preceding Christmas. The airport was closed for three days, creating a financial loss of several millions of pounds. The following months, less successful drone incidents also disturbed traffic at Changi Airport (SIN) in Singapore and at London Heathrow (LHR). To raise awareness of this danger and the lack of readiness, Greenpeace activists intentionally crashed several drones against French nuclear plants.

A drone to rule them all

In a similar fashion to the airports that have decided to rely on falconry to prevent birdstrikes, Fortem Technologies has decided to fight fire with fire. The US-based company offers several solutions to secure sites at risk from drone threats.

A centralized system called SkyDome relies on an array of sensors, cameras and radars to monitor the surroundings and identify potential threats. The integrated artificial intelligence is capable of differentiating a bird from a drone, and to judge if the latter poses a threat or not.

Once the threat is identified, SkyDome sends the HunterDrone capable to intercept the culprit and to fish it out of the air using a projectable net.

Fortem Technologies has recently caught the interest of the U.S. Department of Defense (DoD). On February 3, 2020, the company announced it had been awarded a contract through the Defense Innovation Unit (DIU). While the price of the contract is unknown, it appears that the DoD chose to acquire the whole set of solutions. “Fortem has a number of technologies that can help protect military bases without adverse effects to local communities,” the manufacturer said.

The Israeli company Rafael also offers a centralized system, but with a different solution. Named DroneDome (in reference to the Iron Dome that defends Israel from missile threats) it relies either on a precise jammer, or on a powerful laser. It was this system that put an end to Gatwick's mayhem. It was also used in 2018 to secure the G20 Buenos Aires summit.

Man-portable solutions also exist. During the last national day in France, the military presented to the officials two anti-drone rifles (the Nerod F5 by the French-based MC2-Technologies and the DroneGun Tactical by the Australian company DroneShield). The purpose of those Star-Wars-like devices is not to destroy the enemy drones as one could expect, but to jam their signals.

When they lose contact with their control base, drones usually go back to their takeoff point or stay in stationary flight until they run out of battery. That solution avoids for dangerous debris to fall and create collateral damages, for example onto a crowd during an event.

  • COVID-19 is changing the Air Force’s cyber training

    COVID-19 is changing the Air Force’s cyber training

    Mark Pomerleau WASHINGTON — The Air Force is ensuring its mission essential cyber training goes on during the global COVID-19 pandemic but officials are also delaying some training related to the service's networks. “When all this kicked off, we prioritized all of the mission essential courses that are supplying operators to the cyber mission force. We wanted to make sure that those units continue to get the trained operations that they needed so that their readiness levels didn't suffer,” Lt. Col. Jonathan Williams, commander of the 39th Information Operations Squadron, which provides intermediate cyber weapons system training to airmen, told C4ISRNET. The cyber mission force are the teams each of the services provide up to U.S. Cyber Command. In addition to training cyber mission force personnel, the 39th IOS also trains specific weapon systems for the Air Force network (AFNET), which were either postponed or reduced class size to ensure students are safe. The reduction in those Air Force specific courses have allowed the mission essential courses to reduce in person class sizes for classified work that can't be done remotely to ensure the proper social distancing measures are taken. To learn outside the classroom, the schoolhouse is relying on a partnership with Carnegie Mellon for an entirely online cyberspace fundamentals course, Microsoft Teams and WebEx. Students also don't have to necessarily travel to the 39th in Hurlburt Field, Florida for some training. They can remotely take courses such as the cyber fundamentals course online saving money for temporary duty travel. Williams said he expects to see more of that in the future. The remote tools have also allowed students to gain a unique experience with members of the operational force, while simultaneously saving the taxpayer money. Students are able to hear from operational commanders and operators and even participate in exercises with units. Previously, the students would have to travel to those units to participate, but now, they can dial in. “That helps us in the classroom hit it home. We get those war stories to use in the classroom and the students actually, those light bulbs start to turn on and it really starts to hit home,” TSgt Jonathan Zinski, a course instructor, said. “Now that we have more of an eye-opening capability to use some of our virtual tools, we've actually been able to enroll and participate an entire team of instructors and cadre here at the 39th IOS to participate in a no-kidding virtual exercise with an operational unit to not only hone our skills and help some of our instructors here bring the lessons learned into the classroom but to also help the operational units from our standpoint and help them get better at their jobs.” This experience also gives the students a flavor of what to expect at their units prior to arriving. Officials explained that while the actual courseware didn't change, the schoolhouse shifted the courseware and maneuvered the syllabus to accommodate students doing a combination of distance learning and in person classes. They looked at what courses needed to be conducted in person, then worked around that to ensure the class sizes were small enough while supplementing with remote learning tools. The pandemic has also accelerated certain initiatives the school planned to undertake at a later date. Williams said one includes combining cyber mission force and AFNET defensive cyber training. He said they are re-imagining the defensive cyber training pipeline with something they're calling defensive cyber operations initial qualification training. “Instead of creating a blanket training for each of these weapon systems, we're trying to integrate the AFNET systems with the CMF where it makes sense and also tailor the training,” he said, noting this should be up and running in October regardless of COVID-19. This re-imagining was always planned, but Williams said COVID accelerated it. The adaptations the 39th has been forced to make as a result of the pandemic has rendered some valuable lessons as well. Williams said some initiatives never would have been considered if the pandemic didn't hit. He explained officials are turning a conference room into a recording studio so instructors can either deliver training to students in a separate room or record lectures for students to view later. https://www.c4isrnet.com/cyber/2020/07/27/covid-19-is-changing-the-air-forces-cyber-training/

    Germany cautious as France leads European defense initiative

    France is leading a 10-country defense initiative in a bid to "face new threats" outside existing structures. Germany is wary that the project could entangle its military in foreign interventions and undermine the EU. Defense ministers from 10 European countries gathered in Paris on Wednesday to set the agenda for the European Intervention Initiative (EI2), a defense coalition spearheaded by French President Emmanuel Macron. "To face new threats, Europe needs a strong defense," the French Defense Ministry said in a tweet after the meeting. "With the European Intervention Initiative, 10 European countries are committed to its protection." EI2's goal is to create a results-based common strategic culture that allows for rapid response joint military operations, including in humanitarian efforts. As such, it is not aimed at establishing a supranational European army. However, as an initiative outside EU and NATO frameworks, the French Defense Ministry has tried to alleviate concerns that it would undermine defense structures in the bloc and alliance. "With the European Intervention Initiative, the whole European Union and the European pillar in NATO will also be strengthened," it added. 'Germany felt pressured' But France's efforts have done little to placate concerns in Berlin, which Paris sees as a pivotal actor in the initiative. Claudia Major, senior international security associate at the Berlin-based German Institute for International and Security Affairs (SWP), told DW that German officials are wary because "it's explicitly and deliberately organized and set up outside the European Union's structures." "For the Germans, making a deliberate attempt to setting up something meaningful outside the EU's structures — and outside NATO — is not seen as a positive move but rather as undermining the EU," Major said. "In the end, Germany felt pressured to agree and engage in the initiative, because otherwise all the talk about France and Germany being the engine of Europe and the heart of Europe, and driving European integration and cooperation forward, would look cheap, wouldn't it?"
