"They were coming at us like bees". "We would kill one lot and then more would appear. It was the most amazing thing." Lt Col Twitty, Commander 3rd Battalion 15th Infantry, Operation Iraqi Freedom, Iraq, 2003.
Swarms in nature have always intrigued humans because individually the animals or the insects do not appear to have intelligence but in a swarm, they are able to move as a cohesive intelligent formation capable of taking actions befitting an intelligent life form. Some of the world’s largest swarms in animal kingdom include mosquitoes, Argentine Ants, Christmas Island Crabs, krill, springbok, and locusts. Peter Miller, in Swarm Theory brings out that swarm intelligence works because of ‘simple creatures following simple rules, each one acting on local information’ and also that, a smart swarm is a group of individuals who respond to one another and to their environment in uncertainty, complexity, and change.
The use of swarms in warfare has been observed for over 2000 years, some examples include:
Swarming has also been looked in to by US Military institutes in academic studies and war games. RAND has studies by John Arquilla and David Ronfeldt, ‘Swarming and the Future of Conflict’, 2000; Sean J.A. Edwards, ‘Swarming on the Battlefield: Past, Present, and Future’, 2000; and Sean J.A. Edwards, ‘Swarming and the Future of Warfare’, 2005. In the last document, the author has opined that:
A new approach to achieve coordination amongst a system of large number of simple robots has emerged during biological studies of swarms in nature as well as during applications of Artificial Intelligence in to mechanical swarms it is called ‘Swarm Robotics’. Ant robots are swarm robots that communicate via trail of markings, for example, heat, odor, light, chemical substances, and transceivers.
Microbots is a generic term applicable to very small robots spanning robots of sizes from, small robots (<100 cm), minirobots (<10 cm), milirobots (< 1 cm), microbots (<1 mm) to nanobots (
All of the above projects and many more on similar lines have been funded by military R&D agencies including DARPA. All have military applications as is evident from the fact that the U.S. Military is looking at incorporating roles for swarms in its transformation programs. These swarms of intelligent UGVs, UAVs, and UUVs are intended to sense, recognize, and adapt to the changing situation. The sensor networks will be self-aware, self-healing, and self-defending.
In October 2015, US Army tested swarms of commercial off the shelf drones for applications in the military. Barry Hatchett of the Army's Program Executive Office for Simulation, Training, and Instrumentation stated, “It has been proved that consumer [drones] can be used for intelligence, surveillance and reconnaissance, distraction tactics and, in the future, the ability to drop small munitions."
In a landmark trial, this year the US Navy’s Low-Cost UAV Swarming Technology (LOCUST) program aims to have thirty drones flying together without having to be individually controlled, maintaining separation safely like a bird swarm. The operator would be piloting the whole swarm as a single unit instead of controlling individual UAVs. The trial would have far-reaching impact upon future of swarm warfare in the US armed forces.
The day is not far when the battlefield would graduate from ISR microbot swarms to weaponised microbot swarms carrying new age explosives delivered ingeniously into the enemies heart. The technology would leap frog to provide counter swarms as also counter-counter swarms. The era of the small and many appears to be dawning on the battlefield.
“I need a stealth bomber that’s going to get close, and then it’s going to drop a whole bunch of smalls – some are decoys, some are jammers, some are ISR [intelligence, surveillance, and reconnaissance] looking for where the SAMs are. Some of them are kamikaze airplanes that are going to kamikaze into those SAMs, and they’re cheap. You have maybe 100 or 1,000 surface-to-air missiles, but we’re going to hit you with 10,000 smalls, not 10,000 MQ-9s. That’s why we want smalls.”
