Three years ago, I speculated in my blog that fairly low-tech unmanned aircraft, UAVs, or drones could defeat very expensive missile systems after a giant Saudi oil facility was attacked with high precision causing enough damage to reduce the global oil supply. Even though there was a missile defense system in place, the attack came from a swarm of small low-flying drones and cruise missiles that defeated the existing missile defense system.

I called for an increased emphasis on defense against this type of attack, and since then, there have been many worldwide new programs focused on developing this kind of threat as well as new defense systems. The recent Russian attacks on Ukraine’s infrastructure and the Ukraine attacks against Russian air bases appear to be a demonstration of what I expected, namely a fundamental change in offense and defense.

I pointed out in my post that swarms of such weapons to surprise and exhaust even the most competent defenses could mark a radical change in warfighting. I wrote that “drones could target critical parts of the exposed grid, disperse biological agents, target crowds at sports events, or even parking lots of shopping centers.” Unfortunately, my worst fears have come to pass with the Russians targeting the cities and critical infrastructure of Ukraine. Now Ukraine has struck back, and the nastiness is only going to be even nastier with more attacks from both sides. The balloon has gone up. But wait there’s more. The latest Ukraine innovation is drone killer boats backed up by flying drones to find and strike targets at sea. So the air, sea, and space application of killer drones is going to be the new way of war. But where there are new weapons, there are certain to be new counter-weapons.

With the development of fiber laser weapons with a power level of tens to hundreds of kilowatts, a realistic defense against drone swarms is possible if the tracking, pointing, and fire control system works reliably, and if the power supply is of an ample duration, and if enough of such defense system could become an affordable deployment … and of course, the weather cooperates. Boeing has created “an anti-drone death ray truck” that may defeat the ifs, but there are a lot of ifs and as usual, the offense is already a step ahead of the defense.

What about those new all-weather high-power microwave weapons such as the Ratheon Phaser to attack the controls and brains of the drones so that they become dumb rocks instead of brilliant pebbles?  High-power microwave weapons are being developed by many countries and they will be important.  This will be a story of brains versus beams, and the details will be written as the old game of offense versus defense is repeated again and again. In any case, there is no question that the game has begun and when new technology is created, people will find a way to apply that technology to warfighting.

An eventual development could be the proliferation of low-cost killer drones, and they could become the weapon of choice for ground forces, law enforcement, and maybe terrorists or even your neighborhood crazy guys who already are using weapons developed for the military. It is likely that such killer drones will initially be under the control of an operator, but quite possibly in a few years, they will be employed using artificial intelligence to search out and target predetermined targets when they are recognized by the smart sensor on the killer drones.

Survival of soldiers and military surface systems is possible if they can move, hide, defend, and shoot back, but there is not going to be a so-called “last move” in this contest of energy weapons versus drones. There may have to be an eventual change in the tactics of all surface warfare. It could be just too dangerous for high-value targets to try to survive above ground.  Maybe survival would be achieved by deploying in tunnels and caves. But what about drone swarms used by terrorists against civilian targets?  A logical step would be to ban such weapons, but we have not done this with assault rifles. Instead, children are trained to respond to an active shooter in their schools. I wonder if children will have to return to “duck and cover” when sensors detect a killer drone swarm approaching their playground?
