How cheap drones are transforming warfare in Ukraine

One question is whether drones will be able to stay cheap as armies become more accustomed to defending against them. Forthcoming research by Jack Watling and his colleagues at the Royal United Services Institute, a think-tank in London, which draws on Ukrainian military data, suggests they may not. An FPV drone that has a good chance of getting through and achieving a kill against an armoured vehicle, they argue, requires fancy features such as infrared sensors for night missions, a high-quality radio which is resistant to interference from nearby drones, a biggish antenna and enough thrust to carry 5kg of high explosive.
