Counter-unmanned aerial system (C-UAS) specialist Fortem Technologies has seen a growing military interest in its systems, the company told Janes , with the US-based firm emphasising an interception approach to tackling potential UAS threats.
Fortem Technologies' SkyDome is an end-to-end system encompassing several elements that can be operated separately or as part of an integrated approach. This comprises artificial intelligence (AI)-based software SkyDome Manager that includes ThreatAware, a capability that can analyse input from several sources and sensors.
These sources include the company's TrueView radar, which can help to detect ‘dark' UASs that do not emit radio frequency (RF) or other signals. The overarching system also includes DroneHunter, a multirotor UAS that can intercept rogue UASs using a net tether.
Adam Robertson, Fortem's co-founder and chief technology officer (CTO), said the company opted for the DroneHunter approach for several reasons. First, it can help to avoid collateral damage. Second, it means that the targeted UAV can be brought back for forensic analysis.
”That allows us to figure out where the source is - really we're interested in stopping the source of the threats, not the object that was threatening us,” said Robertson.
The company sees potential for the systems in both fixed installations and mobile platforms, as well as on temporary sites, he noted.
Robertson added that Fortem has been working to increase the autonomy of the system. While it still requires human supervision, the system can function independently to varying degrees depending on the rules of engagement.

By Oriana Pawlyk If Dan Sullivan could use small drones to keep an eye in the sky over U.S. air bases, he would. But that may be a future strategy to survey wildlife lurking near military airfields, posing a risk to aircraft. Drones would negate the need for airmen to suit up and wade through swampy areas around bases to look for animals. And "if your drone is equipped with a forward-looking infrared, at night it could pick up deer, hogs, coyotes ... and having that drone pick up heat flying around, that would be a great asset for a BASH program," Sullivan, the Air Force's wildlife biologist and the Bird/Wildlife Aircraft Strike Hazard chief, said in a recent interview with Military.com. While drone use remains debatable in terms of safety and vulnerabilities, Sullivan said there is a growing need for them and other technologies as wildlife finds refuge near installations that house major aviation operations. But for now, he said, he'll settle for having more airmen trained in spotting bothersome wildlife and how to safely confront it. "I'm looking to institute a more in-depth training [program] here at the [Air Force Safety Center], more for folks that are boots on the ground." 'A Little War' Sullivan, who oversees the BASH program, which is headquartered at Kirtland Air Force Base, New Mexico, said he sees the "threat" of wildlife increasing because the U.S. has some of the best wildlife conservation programs in the world.

Hypersonic vehicles fly through the atmosphere at incredibly high speeds, creating intense friction with the surrounding air as they travel at Mach 5 or above – five times faster than sound travels. Developing structures that can withstand furnace-like temperatures at such high speeds is a technical challenge, especially for leading edges that bear the brunt of the heat. To address this thermal challenge, DARPA recently announced its Materials Architectures and Characterization for Hypersonics (MACH) program. The MACH program seeks to develop and demonstrate new design and material solutions for sharp, shape-stable, cooled leading edges for hypersonic vehicles. A Proposers Day describing the program will take place January 22, 2019 in Arlington, Virginia: https://go.usa.gov/xEcEy. “For decades people have studied cooling the hot leading edges of hypersonic vehicles but haven't been able to demonstrate practical concepts in flight,” said Bill Carter, program manager in DARPA's Defense Sciences Office. “The key is developing scalable materials architectures that enable mass transport to spread and reject heat. In recent years we've seen advances in thermal engineering and manufacturing that could enable the design and fabrication of very complex architectures not possible in the past. If successful, we could see a breakthrough in mitigating aerothermal effects at the leading edge that would enhance hypersonic performance.” The MACH program will comprise two technical areas. The first area aims to develop and mature fully integrated passive thermal management system to cool leading edges based on scalable net-shape manufacturing and advanced thermal design. The second technical area will focus on next-generation hypersonic materials research, applying modern high-fidelity computation capabilities to develop new passive and active thermal management concepts, coatings and materials for future cooled hypersonic leading edge applications. Both technical areas will be described in a Broad Agency Announcement solicitation expected in mid-January 2019 on DARPA's FedBizOpps page here: http://go.usa.gov/Dom. The MACH program seeks expertise in thermal engineering and design, advanced computational materials development, architected materials design, fabrication and testing (including net shape fabrication of high temperature metals, ceramics and their composites), hypersonic leading-edge design and performance, and advanced thermal protection systems.
