Dual-Use Drone Swarms

Quadrotor — Weaponizing individual drones is just the beginning…

By Chris Rawley

Last winter over at Information Dissemination, I made the observation that swarming robots will irreversibly transform warfare, and I hold to that argument. The discussion and progress in this area is developing quickly. Much of this conversation involves non-military uses for drone technology, but as with many tools, there are also applications for warfare. A host of militarily useful scenarios can be envisioned to employ very small unmanned naval platforms in a non-lethal fashion.

In the videos below, quadrotors are used to perform simple construction tasks. The technology that is today viewed as modern performance art could some day be utilized to build an expeditionary forward operating base remotely. A C-130 would fly over a likely FOB site and deploy hundreds of UAVs, which would quickly go to work filling Hesco Barriers and building fighting positions all night long based on a pre-programmed design, a scoop of sand at a time. Out of power, the drones could then land on the FOB and relay observations to the incoming troops. The site would be defensible as soon as the first Marines arrived, leaving Sea Bees for more valuable construction projects.

Researchers in the UK are developing autonomous vehicles which will replace the tedious role of scuba divers who painstakingly seed damaged coral reefs. The alternative being worked is to allow “multiple small autonomous robots following a simple set of rules and seeking out coral fragments and re-cementing them to the reef. But first the robot needs to be driven by a computer ‘trained’ to recognise coral fragments from other objects such as rocks, litter, sponges and other sea creatures… The swarm of autonomous underwater robots will operate according to a simple set of ‘micro-rules’ to seek out coral fragments and re-cement them to the reef.”

A swarm of nano-UUVs similarly equipped as the “coralbots” could quietly infiltrate an enemy naval port and use sensors and algorithms to recognize seawater intakes on ships. These intakes are indispensable on just about every vessel and are used for heat exchangers cooling engines and various pumps, to make fresh water for the crew, and to propel water-jet equipped ships like the LCS. The UUVs could inject a combination of mud or sand scooped up from the harbor with epoxy into these intakes, effectively rendering the fleet useless and unable to get underway. A similar attack could gunk up the intakes to power plants, refineries, and other coastal infrastructure.

The idea of drones mimicking insects might have other applications. Like bees or fire ants who can subdue a much larger predator, disposable micro-UAVs – too small to defeat with CIWS or other weapons systems – might swarm an Aegis combatant, each spraying a tiny amount of radar absorbent paint on the SPY array, achieving a mission kill of the most powerful air and missile defense system in the world.

Of course, these sorts of aerial swarms might be vulnerable to jamming, EMP, and the like, but here, LT Matt Hipple offers some recommendations to build resiliency into drone swarms. The rapid evolution of drone swarm technology can be expected to continue until concepts like these are deployed operationally; likely sometime in the next decade.
