\t\t\t\t\t\t\t\t\t\t\t\t\t\tThe ongoing Russia-Ukraine war has had an outsized influence on the development and use of small drones in the U.S. Keith Button spoke to manufacturers and researchers about the evolving landscape. <\/p>\n
On a recent visit to Ukraine, Brian Streem watched Ukrainian soldiers swapping out components of off-the-shelf consumer drones to modify them for battle.<\/p>\n
\u201cI\u2019m sitting here watching frontline military guys de-soldering this commercially available device, removing a chip, and I\u2019m like: \u2018How the [expletive] did anyone figure this out?\u2019\u201d says Streem, chief executive of New York-based Vermeer, which manufactures a visual navigation substitute for GPS. \u201cThere are certain things that we have absolutely learned about \u2014 like how these systems need to be integrated into other subsystems of the drone \u2014 that you just don\u2019t know without doing it and without seeing it.\u201d<\/p>\n
Historically, experience gained from the battlefield has been applied to future doctrine and technology planning, due to the bureaucratic nature of weapon development and acquisition. But the Russia-Ukraine war has been different. Both countries are rapidly adopting and evolving their technologies, often updating them in a matter of days.<\/p>\n
In the U.S., lessons learned since the start of Russia\u2019s invasion in early 2022 have already prompted academia, industry and military customers for the technology to shift their research priorities to reduce development timelines to months or even weeks.<\/p>\n
Taking another lesson from the war, advocates for building up U.S. drone production are focusing on developing supply chains to easily source cheap components not made in China.<\/p>\n
One means of achieving that objective could also have the side effect of reshaping U.S. airspace. Proponents argue that loosening FAA restrictions on small drones would expand U.S. commercial and consumer use, and thereby boost domestic drone manufacturing capacity.<\/p>\n
The war has \u201cchanged our whole doctrine about how we\u2019re going to wage drone warfare in the future,\u201d says Jamey Jacob, an Oklahoma State University aerospace engineering professor and small drone and counter-drone researcher. That change, he says, has been driven by \u201cwhat they\u2019re doing there and how quickly they are doing it, adapting frontline modifications and manufacturing, rethinking everything.\u201d<\/p>\n
Learning on the fly<\/p>\n
U.S. researchers and entrepreneurs in the past were accustomed to developing and fielding new drone technologies on two- to five-year timelines, but Ukrainian and Russian soldiers have been adopting modifications and countermeasures within weeks. That\u2019s been the case particularly with small drones, Jacob says.<\/p>\n
\u201cWe can no longer fight frontline battles like we had in the past,\u201d Jacob says. \u201cWe\u2019re seeing what that looks like now and how different that is from what we have prepared for.\u201d<\/p>\n
The question now, he says, is how the U.S. can make a similar pivot, which includes how to manufacture the millions of small drones and their components that might be required for a future war. The U.S. Army plans to buy 1 million drones within three years, Reuters reported late last year, and then potentially ramp up to purchasing at least a half million drones per year, compared to its current outlay for 50,000 drones per year.<\/p>\n
The Ukraine war has been \u201can accelerant\u201d for small drone development in the U.S., especially by the Army and Marine Corps, says Andrew Hunter, a former Air Force acquisition chief who now consults for the defense industry and investors. His clients see a huge opportunity for drone manufacturers, he says.<\/p>\n
\u201cThey see the effectiveness of what they do as being dramatically demonstrated\u201d by the war, he says.<\/p>\n
For Streem, who has five employees in Ukraine and an apartment in Kyiv, the war has also provided real-world development experience and data-gathering opportunities that would have been tough to replicate otherwise. For instance, suppose Vermeer wants to schedule a flight test in the U.S., he says. The company might get some time on \u201csome California missile base next June.\u201d<\/p>\n
\u201cGreat, that\u2019s nine months away from now,\u201d Streem says. \u201cWhat else am I supposed to do until then?\u201d<\/p>\n
Vermeer is developing software that matches images from visual and infrared cameras, lidar, inertial measurement units and other inputs to digital maps to provide a radio-silent GPS substitute for drones carrying 40-60 kilograms of payload on 1,000-kilometer flights. Perfecting that software requires repetition.<\/p>\n
\u201cGetting stuff like this to work requires firing it on drones and missiles a lot, and taking a look at the data, figuring out what worked and what didn\u2019t work, and then why it didn\u2019t work, and then doing it again,\u201d Streem says.<\/p>\n
The speed of need<\/p>\n
In adopting lessons from Ukraine, the Defense Department and its contractors have placed a premium on quick turnarounds and lower costs per unit.<\/p>\n
Some of the funding requirements for small drone research and development for the Air Force, Army and other defense programs have shifted since 2022 to prioritize low-cost options and need-it-yesterday results, says Moble Benedict, a Texas A&M University aerospace engineering professor and owner of Harmony Aeronautics, a drone development company.<\/p>\n
\u201cThey want very, very rapid turnaround times now. It\u2019s not like a typical DOD kind of program where things happen in years,\u201d Benedict says. \u201cThey want these products in months \u2014 two months, three months. They\u2019re feeling the urgency to get into this drone space.\u201d<\/p>\n
And many small companies are willing to oblige. \u201cThey are willing to do anything for success, so they will spend 18-hour days\u201d to meet the stepped-up timelines, he says.<\/p>\n
In addition to speedy development, the Pentagon is looking for relatively low-cost tech. Companies pitching counter-drone concepts are asked to present their \u201ccost per kill,\u201d Benedict says. \u201cIf you\u2019re trying to take out a large UAS [unoccupied aerial system], a large asset costing many millions of dollars, you can send a very sophisticated UAS. But do you really want to send a sophisticated UAS to kill a $200 toy drone with a bomb strapped to it?\u201d<\/p>\n
Building a small drone from off-the-shelf parts is not complicated, he notes: You need an electric motor for the rotors, a battery, an electronic speed controller to convert the battery voltage for the motor, a power distribution board, a receiver for incoming radio signals, a flight controller to convert those signals to control the aircraft, a GPS receiver, a camera, a thermal camera, lidar, a 3D-printed frame, screws and wires.<\/p>\n
But for that approach to really be cost-effective, the U.S. needs to start domestically mass-producing small drone components, Benedict says. Under Pentagon requirements, defense drones can\u2019t use parts or equipment from China, Iran, North Korea or Russia. But relying soley on approved U.S. suppliers can be expensive. The same kind of motor that sells for $20 from a Chinese vendor will cost $100 from a U.S. manufacturer, he says. U.S.-made electronics for drones are particularly expensive \u2014 driving the overall cost of a small drone to upward of $1,000.<\/p>\n
\u201cIf you\u2019re free to use the cheapest available motor or the cheapest available battery you can buy online, you can build really cheap drones,\u201d he says. \u201cBut then the problem is all these supplies are coming from China.\u201d<\/p>\n
One way to incentivize this domestic supply chain could be for FAA to loosen flight restrictions for commercial and recreational small drones, says Clinton Purtel, a business professor and aerospace supply chain expert at Oklahoma State University. This in turn could boost customer demand.<\/p>\n
\u201cIndustry follows where you can use and scale the thing,\u201d Purtel says, noting that to date, U.S. manufacturers haven\u2019t made large-scale investments in producing small drone components because there\u2019s been no need.<\/p>\n
\u201cHow do we get the pivot now so the production and specification is there and we don\u2019t have the critical path moment of: \u2018Oh crap, now we need it, now we\u2019re in combat?\u2019\u201d Purtel says. \u201cHow do we get on a level playing field for these things that are attritable, just no different than firing a round through a gun?\u201d<\/p>\n
Part of the reason for the urgency in the U.S. is the surprising lethality and precision that small drones have proven in Ukraine, Benedict says.<\/p>\n
\u201cOne thing the world realizes right now is the kind of damage these drones can do and the kind of targeted attack that these guys can unleash,\u201d he says. \u201cIt\u2019s all because the Ukraine war has shown the world what you can do with drones.\u201d <\/p>\n
