This podcast discusses drone swarms, which can be used at sea, on land, in the air, and even in space, are fundamentally information-dependent weapons. No study to date has examined drone swarms in the context of information warfare writ large. This article explores the dependence of these swarms on information and the resultant connections with areas of information warfare—electronic, cyber, space, and psychological—drawing on open-source research and qualitative reasoning. Overall, the article offers insights into how this important emerging technology fits into the broader defense ecosystem and outlines practical approaches to strengthening related information warfare capabilities.

Your article explores the dependence of drone swarms on information and the resultant connections with areas of information warfare—electronic, cyber, space, and psychological warfare—drawing on open-source research and qualitative reasoning. Put this in context for us, please.
(Kallenborn)
The context of the discussion is looking at drone swarms—a rapidly emerging technology that numerous states are developing. Obviously got the big players—China, Russia, the United States are all developing this technology. But even smaller powers, like South Africa. And this technology is even already being used in combat. We saw just last year that Israel used a drone swarm in combat in the fight against Gaza. Now, before jumping into these sort of larger issues of information warfare, it’s important to understand briefly what we mean by “drone swarm” here.
We’re not necessarily talking about simply large numbers of drones used en masse, which is often how the term is used within media, but really what we’re talking about is drones that have some level of communication and coordination between them so that they’re operating effectively as a singular unit instead of, say, 10, 15 individual drones.
Now, what that means is there’s potentially a range of capability within that. Because if we’re talking about simply coordination and communication at the basic level, that’s a pretty simple thing. So in the case of like the Israel example, likely all they’re really doing is just doing some coordinated searches over an area to help identify a target. It’s not anything all that fancy or unusual, but we can imagine in the future how artificial intelligence and autonomy may make coordination communication fairly significant. You could imagine, for example, a drone swarm that’s made up of multiple different types of drones operating in different domains with different types of payloads where they’re intelligently selecting, like, “Alright, let’s use this antitank weapon against this identified tank over here, and we’re going to send our antipersonnel weapons to this infantry unit over here,” and collectively sort of adapt and engage with the reality on the ground working across multiple domains, and all autonomously.
But the important thing, and what we’re going to get at in this article, is that regardless of that complexity, one of the key issues when it comes to drone swarms is information warfare, and, particularly, their dependence on those various subsets: electronic, cyber, space, and psychological warfare.
(Host)
Let’s start with electronic warfare. Electronic jamming: What do we need to know?
(Kallenborn)
We can start with individual drones because that’s the simple example here. One of the things that we’ve seen is that electronic jamming has been a really common form of attempting to defeat that system—namely, because drones typically rely on some sort of communication signal between the operator and the actual drone platform itself. So the idea is if you sever that communication link, then the drone may not necessarily be able to operate at all.
And that problem scales extensively when we talk about drone swarms because, necessarily, you have that same problem. You have an operator who has to send links and information to that swarm. But it becomes more complicated because to get at that point, the key issue of swarming is that communication and coordination between the different drones, which means you have another opportunity to jam, and, particularly, that inner-swarm communication. Because if you break down that communication, the notion of a swarm stops being meaningful.
Now one of the open questions, though, is how exactly that works in practice. Based on the way that the algorithms work from having, say, a dedicated leader—that sort of helping organize things to massively decentralized approaches—to having different communication pathways through a complex network. So how exactly jamming might work in practice may vary a lot.
And of course, if we’re talking about multidomain swarms where you start getting undersea drones interacting with surface vehicles, that becomes more complicated. But, nonetheless, the notion of jamming signals is equally appropriate there.
(Host)
What about cyber? What do we need to know?
(Kallenborn)
There is sort of a silly depiction, but I think it has some seriousness to it, of drones as sort of flying computers. And in a sense, that’s what they are. They’re kind of onboard systems that manage all aspects of the drone’s flight from specific flight controllers that manage the propellers and the various movement and the habitation of that system.
And when we start talking about drone swarms, that’s even more the case because you now have algorithms and systems to manage that broader communication, that coordination, the broader behavior of that swarm, so that at a very basic level, you may have—say, for example, task allocation algorithms to say, like, “OK, these drones are going over here, these drones are going over here, these drones are going to do this, those drones are going to do that.” And that’s a very cyber-based system, which of course means that it also creates vulnerabilities in the cyberspace for those systems.
So what happens if you have cyberattacks aimed at the systems that control the flight controllers? What happens if you attempt to manipulate those? You could get all sorts of problems, from the drones not operating correctly to crashing into one another, and you can imagine other types of cyber activities.
So, for example, if you’re using artificial intelligence-based machine vision in the swarm to help navigate the world around it, that could potentially be manipulated through cyber means by, for example, it manipulating the training data that goes into creating those machine vision systems through what are called, “(artificial intelligence or) AI poisoning attacks.” Conversely, you can also imagine using cyber to, say, again, break that link between the operator and the actual system itself. Except, rather than using . . . jamming the actual signal, you are manipulating the system that is actually responding and taking in those orders. And then, at an extreme level, you could imagine cyber being used to actively take control of and manipulate the swarm, which is perhaps the scariest, where your friendly swarm is now turned against you and destroying your own military forces, which could be quite bad.
(Host)
What about space warfare and the Global Navigation Satellite System? How do they relate to drone swarms?
(Kallenborn)
Yeah, so, there’s a couple dimensions to it. Firstly, there’s obviously the communication element. At the moment, most of the drone swarms are very sort of tactical, very short-range type operations. But as we start scaling, you could potentially look and need satellite-based communication to relay some of those signals. Likewise, we know that, at least at the moment, many of these drone swarms are heavily dependent on global position navigation, a positioning system for navigation timing. Basically, they need to understand where are they potentially located in space?
Now that’s one place where technology is developing, and there has been work on using a more autonomous, image-based recognition to help the swarm actually navigate. But, at the moment, there’s a close dependence on (the Global Positioning System or) GPS. But how exactly that works is again going to be very dependent on the nature of the s...
