Drones: How Small Flying Machines Are Changing Modern War

Key takeaways

• A drone's power is not its bomb but its speed from seeing to striking. A quadcopter flies by changing the speed of four small motors, a matchbox-sized flight controller corrects it hundreds or thousands of times a second, GPS tells it where it is, and radio links carry orders out and video back.
• Drones went from a 1918 experiment and 1930s target planes (the British Queen Bee gave the 'drone' its name, by the most-told story) to Israel's decoys in the Bekaa Valley in 1982 and the armed Predator in Afghanistan in October 2001, flown from Nevada more than 10,000 km away. For over a decade, killer drones were weapons only rich countries could afford.
• In the 44-day Nagorno-Karabakh war of 2020, many analysts believe drones were among the most important factors. In Ukraine, cheap FPV drones of about $400 to $500 took over: Ukraine produced or bought roughly 1.5 to more than 2 million small drones in 2024 (depending on the source), and a London research institute estimates they cause about 60 to 70 percent of the damage to Russian military vehicles.
• Attacking is cheap and defending is expensive. Russia launched 810 drones and 13 missiles in one night in September 2025; Iran fired about 170 drones and more than 150 missiles at Israel in April 2024 (about 99% intercepted, per Israel); and NATO jets were used against a few drones, many of them foam-and-wood decoys, over Poland in September 2025. Jamming, fibre-optic drones, interceptor drones, nets and lasers are the answers and counter-answers.
• In Operation Spiderweb (1 June 2025), Ukraine says 117 drones hidden in trucks hit 41 aircraft; independent analysts confirm about 12 to 14. Distance no longer protects, and drones are starting to lock onto targets by themselves. The UN Secretary-General and the ICRC have called for international rules on autonomous weapons by 2026; the real question is whether humans stay the final decision-makers.
