Recently conflicts in the Ukraine and Syria have clearly shown the danger that small drones (UAVs) can pose to military units on the ground. To adapt to this threat the US Army has been testing a Stryker Infantry Carrier Vehicle that has been refitted with a laser and electronic countermeasures that can track and disable drones.
High-tech cameras and jamming devices can detect drones, track them and even disable them. If for some reason the drones still keep on coming the Stryker is equipped with a Mobile High Energy Laser (MEHEL) that lets it blast the drones out of the sky. In two test sessions the laser-equipped Stryker was able to successfully blast over 50 drones out of the sky—a number beyond what was expected. Besides shooting down drones, the army also plans to use the laser to blow through defenses and even stop incoming rockets and artillery shells.
While there are more cost effective anti-drone technologies, the Stryker’s ability to identify, track and disable a drone with a single platform could make it a useful tool to protect soldiers from the threat of drone strikes.
The Navy plans to put its new MQ-4C Triton long-range patrol drone into service sometime next year. The drone is based off the same design as the Global Hawk, but new software upgrades give it the ability for enhanced autonomous operations.
The Triton will come with a Traffic Alert and Collision Avoidance System (TCAS) which will allow its operator to identify and avoid other aircraft independent of any other air traffic control data. The new software upgrade will also allow a single drone operator to control multiple drones at the same time.
The Navy has successfully tested the new software and while it does not make Triton drones completely autonomous, it’s an important step towards fully autonomous flight. Given criticisms of its drone programs the various military branches are taking a cautions approach towards introducing autonomous operational ability for their drone fleets.
Given a robust TCAS, it’s possible that the Triton drone will be allowed to operate in same airspace as civil aircraft traffic—something the Global Hawk cannot do. Whether for civil or military application, the end game for TCAS, or sense and avoid systems like it, is for drones to operate by themselves. So keep an eye out for further software upgrades for the Triton if you are interested in how the military is moving forward with this technology.
We all know that Amazon is the clear leader in online sales and that it is also pushing hard to make drones deliveries a reality. It looks like they have the upper hand, especially when you consider that their nearest rivals in online sales—Walmart and Target—are far behind them in developing drone delivery.
But Walmart and Target have a secret weapon that could, if properly used, give them an advantage against the empire of Jeff Bezos. What is that secret weapon, you ask? Their stores!
Both Walmart and Target have thousands of store and distribution centers throughout the nation that could easily accommodate a drone delivery center.
The good folks over has Business Insider Intelligence have put together some interesting info using data from users of The Weather Company App. They found that 49% of users of the weather app live within 6 miles of a Walmart store and that 47% of users live within 6 miles of a Target store. In both cases, around 15% of purchases these individuals made where under $10 and likely would be light enough to deliver by drones. Walmart’s own numbers are even better. On a recent blog the mega retailer said that 70% of the US population lives within 5 miles of a Walmart store.
In comparison only 44% of people live within 20 miles of an Amazon fulfillment center, beyond the range of current drone delivery technology.
There are a lot of ifs here, but if either Walmart or Target can realize this potential and get in the drone delivery game, things could heat up real quick!
The crew from Florida Offshore steadies and lowers the BQM-167 sub-scale drone to the cradle after a recovery demonstration July 22 in the waters off Tyndall Air Force Base, Fla. The ship used for recovery is one of only three 120-foot boats owned by the Air Force. The Florida Offshore crew is contracted through the 82nd Aerial Targets Squadron to help recover sub-scale drones after they are shot down during live-fire exercises.

Drones have revolutionized how war is fought and as drone technology evolves further, their influence only grows. A new drone in the development for the US Air Force will shake things up even further.
In the summer of last year, the US Air Force awarded Kratos Defense & Security Solutions, Inc. a $41 million contract to develop Low-Cost Attritable Strike Unmanned Aerial System Demonstration (LCASD). Basically, they want Kratos to develop a cheap rocket-powered drone that can act as a wingman for expensive state-of-the-art fighters like the new F-35.
But Kratos is not starting from scratch, instead they are redesigning a popular target drone, the Kratos Defense’s BQM-167A. Here is what the the Air Force is expecting for the drone.
- Approximate a fighter jet’s capability to conduct high-g-force maneuvers.
- Fly 1,500 nautical miles in a combat radius.
- Launch and land without runways.
- Carry a 500-pound weapons payload — sufficient for two GBU-39 small diameter bombs, or up to four Hellfire missiles.
Kratos is planning on building these drones for a little as $2-3 million a piece, which makes them incredibly cost-effective for what they can do.

One of China’s largest eCommerce business, JD.com, is at it again. In the next three years the company plans to open 150 drone launch facilities in China’s southwestern Sichuan province in an effort to create a local drone delivery network. Sichuan’s mountainous terrain has for centuries made travel and delivery a difficulty to isolated rural communities, now drones can change that.
Drone Dossier has reported on JD’s work before. Since June of 2016 they have been making live drone deliveries in four test areas throughout China. They are also working directly with Chinese authorities to set up a drone traffic management systems in the areas they operate.
JD has a variety of drones to deliver packages with the largest supposedly able to lift upwards of 50 kg and they are developing ones that can lift around 500 kg! JD’s CEO Richard Liu recently said that drone deliveries would reduce the costs of shipping freight by 70%, compared to conventional truck delivery.
JD is also streamlining the way its uses drones, deciding not to make deliveries to individual address, but instead deliver to one of the thousands of local distribution centers that is has both in cities and in rural areas.
The video below shows JD’s concept. In it a man orders diapers online from a local village. The order then goes to the nearest drone-capable distribution center which packs up the diapers and sends them to the local village via an autonomous drone. Notice that the JD drone in this video is a tri-rotor drone and it appears (3:34) that the box has hooks that latch unto the drones chassis itself to secure the package during transit. The drone drops the package off at another smaller JD distribution center where a local employee picks it up and literally walks it over a few houses to the guy who order the diapers online.
Forget observing construction projects, workers in China are now using drones to assist in building massive bridges.
In China’s Sichuan Province workers are currently building the Xingkang Bridge that when completed will be nearly a mile long and hang over 600 feet above the raging Dadu River. The southwestern province is famous for its river gorge valleys that impede travel.
The first step in creating these massive suspension bridges is to run a pilot cable across the expanse the bridge will traverse and then use this pilot cable to rig up larger and larger cables. Usually a helicopter or boat would be used to run a pilot cable. But this time a drone is being used.
In December, Chinese engineers used a large 6-rotor drone to carry the pilot cable to the other side of the bridge structure. The engineers claim this method is over 100 times more efficient and 80% less costly than traditional methods—not to mention safer. This is also not the first time China has used drones in this manner to help construct bridges.
Such innovative uses of drones show their ability to make things more efficient and cheaper—which when you think about it, are the two keys in making a technology stick. It will be interesting to see what other ways drones can aid construction project.
