UAVs 4.0: ¿Making war easier?

The world is becoming saturated with UAVs, and the technology that underpins these systems is only expected to become more sophisticated.

Next-generation UAV technology (UAVs 4.0) now in development includes: 
  • Additive manufacturing for bulk production
  • Advanced materials for enhanced stealth and smaller size
  • Energy storage, solar powered systems and satellite-based communications
  • Automation, artificial intelligence and machine learning
Advances in AI (Artificial Intelligence) and machine learning could lead to small UAVs that communicate with each other as a cognitive hive mind with the capability to swarm targets, leaving kinetic air defenses with too many targets to engage.

At the same time, advances in nanotechnology could lead to UAVs that mimic birds or insects, such as the Black Hornet, which could be capable of stealthy, close-quarter audio, video and possibly even DNA-sample intelligence collection. More disruptively, these nano-UAVs could engage in highly targeted killings through the injection of poison or self-destruction.

Both software and hardware are at the core of UAVs 4.0 but the physical limitations inherent in hardware do not apply to software, which is more diffuse and rapidly adaptable: Programming UAVs to remain on a “leash,” following warfighters wherever they go, or with the ability to loiter over a designated area and automatically find, fix and engage threats on their own, has tactical implications for war, particularly in the urban battlefield of the future replete with infrastructure that provides concealment for enemy forces.

Last but not least: The introduction of armed UAVs permanently altered the modern battlefield, and new technological advances in UAV technology (UAV 4.0) could do it again: from advanced materials that allow UAVs to fly, roll, run or swim in less forgiving environments, to thinking software than makes them more independent, to stealth technology that renders them even less visible. On the positive side, the intelligence that UAVs provide helps focus lethality on the intended target and limit the risk of civilian casualties and friendly fire incidents. But on the negative side, non-state actors will be able to employ them as well, giving insurgents or terrorists an outsized advantage: “While small drones can be a hazard domestically, their threat to the warfighter is growing as well. Footage of weaponized drones being used by ISIS provides a disturbing glimpse into the group’s Tactics, Techniques and Procedures (TTPs), and the future of asymmetric warfare. We have seen ISIS-controlled drones drop precision bombs on compounds, destroy armor and kill soldiers. And as dangerous as they are now, the lethality of drones will only increase as other nations and non-state actors refine their technology and TTPs.” (Deborah Lee James, former Secretary of the U.S. Air Force)

¿New Hope for Mountain Rescues?

A student team at the prestigious University of Warwick School of Engineering in Coventry, England, has designed an UAV (Unmanned Aerial Vehicle) with the ability to deliver immediate aid and equipment to people in trouble, before a rescue team arrives.

The project’s design lead, Ed Barlow (who has since graduated), knew he had a large-format 3D printer at his disposal. And that meant the team could design and manufacture something different than existing UAVs for aid and supply drops, such as the drones US startup Zipline uses to deliver blood and plasma to Rwandan hospitals: “They all use an airframe that you can go and buy from a shop,” Barlow says. “We needed our own custom airframe, made specifically for long-distance flight with a heavy payload.”

Warwick Associate Professor of Engineering Simon Leigh, who specializes in Additive Manufacturing, guided Barlow’s team during the project. He knew they would 3D-print reusable molds of the UAV body parts and then use them to resin-infuse strong-yet-light carbon fiber to create the finished product. Leigh says it took about one month of continuous 3D printing to finish the molds. After that, infusing the carbon fiber proved a challenge, as well: “We used liquid-resin infusion, which is under the vacuum,” Barlow says. “You apply a vacuum to your carbon fiber on the mold, and then you inject resin into it under the vacuum. That’s generally done on a much bigger scale, with much easier geometric parts than we were using, so we had to invent a lot of really cool tools to do it.”

Why You Should Attend the Military Additive Manufacturing Summit
According to recent reports, the worldwide 3D printing industry is expected to grow to $12.8 Billion in 2018, and is projected to exceed $21 billion by 2020. Manufacturers across a broad spectrum of industries including automotive, aerospace, high tech, and medical products are all piloting and using 3D printing technologies today. However, the US Military is taking an extremely active role in implementing the unique set of tools that additive manufacturing has proven that it can offer to units in resource scarce environments operating under restricted time schedules.

Through the use of 3D printing solutions, the Military is able to enhance the maintenance and sustainment capabilities needed to reduce downtime; minimize the costs associated with having to purchase, transport, and store additional resources; offer more operational flexibility to leaders in the field of logistics; and provide units in remote locations with the ability to reduce the size of their supply chains becoming more self-sufficient and agile in isolated and contested environments.

Additionally, the latest innovation in this field is metal additive manufacturing. This is accomplished by taking a base material, usually in the form of a metal powder and using heat generated by lasers to build a form. Other materials are being explored for additive manufacturing as well. We are beginning to move beyond 3d printing only being extruded plastic polymers and the military is particularly interested in this. The Navy has taken the first steps to explore this technology and the other branches are engaged as well. This forum will offer additive manufacturing solution providers, members from Government, and leaders in academia the opportunity to hear from some of the US Military's most senior and qualified subject matter experts on the future role of additive manufacturing in the Defense industry.
