Drone swarms offer significant improvements to both nuclear offense, the ability to successfully deliver a warhead to a target, and defense, the ability to prevent successful delivery and mitigate consequences. When it comes to chemical and biological weapons, drone swarms can improve both defense and offense, but appear to strongly favor offense by addressing key challenges to delivery. In the future, this could weaken the norms against these weapons and encourage proliferation. – War on the Rocks Photo: Ars Electronica/Martin Hieslmair
