New Spy Drone Flies Non-Stop for a Month

Airbus's Zephyr solar-powered drone flew for 25 days straight during a test-flight over Yuma, Arizona beginning on July 11, 2018. The flight represented a record for aircraft endurance, breaking the previous 14-day record also set by a Zephyr back in 2015.

The long flight has big implications for military surveillance. Drones like Zephyr could loiter over a low-intensity battlefield far longer than current drones can do. The latest high-endurance Reaper drone maxes out at 40 hours in the air.

The propeller-driven Zephyr belongs to a class of aircraft known as “high-altitude pseudo-satellites,” or HAPs. Flying as high as 70,000 feet for weeks or even months at a time, HAPs perform many of the same missions that low-orbiting satellites do.

“The main HAP applications are in telecommunications and remote sensing, both civilian and military,” Flavio Araripe d'Oliveira, Francisco Cristovão Lourenço de Melo and Tessaleno Campos Devezas wrote in a 2016 paper.

Compared to comms satellites, HAPs have the advantages of lower latency and the ability to land for maintenance or reconfiguration, d'Oliveira, de Melo and Devezas explained. For surveillance missions, HAPs unlike satellites can linger over a particular area and could produce images with better resolution, since they fly lower than satellites do.

HAPs could be more vulnerable to enemy defenses, however. Where satellites orbit many hundreds of miles over Earth, beyond the reach of most conventional weaponry, Zephyr — so far the only HAP undergoing realistic testing — attained a maximum altitude of 70,000 feet, well under the ceiling for modern air-defense missile systems such as the Russian S-300.

Also, the drone is slow, with a cruising speed of just 20 miles per hour.

Zephyr and similar pseudo-satellite drones could be best-suited for operations over lightly-defended territory. In 2016, the U.K. ministry of defense bought three Zephyrs for around $6 million apiece in order to evaluate them for potential use by the military and other government agencies.

“Zephyr is a cutting edge, record-breaking piece of kit that will be capable of gathering constant, reliable information over vast geographical areas at a much greater level of detail than ever before,” then-defense secretary Michael Fallon said in a statement.

Airbus is still refining Zephyr, in particular its power-consumption. During daytime, the lightly-built solar-powered drone — which features an 82-foot wingspan and yet weighs just 165 pounds — can fly as high as 70,000 feet while also charging its batteries.

After the sun goes down, Zephyr runs on batteries ... and slowly loses altitude. During the record-setting Yuma flight, the drone dipped as low as 50,000 feet at night.

The challenge for Airbus is to balance weight and power-consumption to produce the optimal flight profile for a particular task. “You have to find the right equation between flying altitude plus battery life, maintaining this or that power,” said Alain Dupiech, an Airbus spokesperson.

It's unclear just how long Zephyr could stay aloft under the right conditions. The drone's lithium-ion battery eventually dies, forcing it to land for maintenance. But battery technology is advancing rapidly, driven in part by consumer demand for electric cars, d'Oliveira, de Melo and Devezas wrote.

In the short term, a maximum endurance of several months is not inconceivable. But longer flights might not be particularly useful for surveillance and comms missions, Dupiech said. “At this stage, most of those missions are not calling for a year and half up there.”

Airbus has scheduled Zephyr's next test flight for October in western Australia.

    More than meets the eye: Army selects next-gen camouflage system

    By: Kyle Rempfer The Army has finally selected a company to provide it with the next generation of ultra light-weight, general-purpose camouflage. The Army's Ultra-Light Camouflage Netting System, or ULCANS, will be an all-weather, state-of-the-art signature concealment system that provides multi-spectral protection for troops and equipment. The program aims to replace the legacy woodland and desert camouflage variants developed in the 1990s, and will be developed in light and dark woodland, snow and alpine, desert, and urban variants. The Army hopes ULCANS will better conceal the signatures of troops and equipment from high-end sensor threats on the battlefield. The contract to produce the next-generation camouflage was awarded to Fibrotex USA Inc., according to a company statement provided to Army Times. The contract is a 10-year, indefinite delivery and indefinite quantity award, with a total value of $480 million. Fibrotex is expected to begin full-rate production in early 2019, according to the company. ULCANS is the result of nearly two years of testing, trials and data collection conducted by the U.S. Army's Natick Soldier Systems Center in Massachusetts. Natick tested camouflage technologies from major global manufacturers against the Army's most advanced battlefield surveillance sensors. Many of the technologies underpinning ULCANS are based on developments by Fibrotex's Israel-based parent company over the last two decades, but have been specially modified for the U.S. Department of Defense. The Fibrotex system will provide multi-spectral camouflage, which conceals objects from detection across several portions of the electromagnetic spectrum at the same time. Traditional military camouflage simply hides an object in the visible spectrum, but the multi-spectral design obscures detection in the infrared, thermal and radar spectrum as well. “Today more than ever, military forces and opposition groups are using night vision sensors and thermal devices against our troops, but by using Fibrotex's camouflage, concealment and deception solutions, we make them undetectable again, allowing them to continue keeping us safe," said Eyal Malleron, CEO of Fibrotex USA. Fibrotex will also deliver the ULCANS material in reversible designs — allowing for the first time a different pattern and capability on each side, enabling soldiers, vehicles and systems to disappear into light or dark woodland, snow or alpine and desert or urban environments in any operational theater. “We have more than 50 years of experience, with thousands of hours in the field and a deep understanding of conventional and asymmetric warfare," Malleron said. "The U.S. Army tested our best camouflage solutions, and the camouflage repeatedly demonstrated the ability to defeat all sensors known to be operating in the battlefield and throughout the electromagnetic spectrum.” ULCANS will also be manufactured stateside, in a new state-of-the-art facility in McCreary County, Kentucky, creating hundreds of new skilled American jobs over the next decade, according to Fibrotex. “I firmly believe we have the best workforce in the country, and that their hard work and dedication has earned these new jobs, helping deliver a vital new military contract from McCreary County," Rep. Hal Rogers, R-Ky., said in a press statement. "I take great pride in knowing that our people are crafting these products to keep our warfighters and allies safe, giving them an edge on the battlefield.” The new facility is being established next to Outdoor Venture Corporation, which is a strategic partner to Fibrotex USA and already designs modular personnel tents and command post tents for the Army. https://www.armytimes.com/news/your-military/2018/11/07/more-than-meets-the-eye-army-selects-next-gen-camouflage-system
