Now look at Ukraine.
The drone has become the signature weapon of the war, but the drone alone is not the revolution. The revolution is the drone system: cheap airframes, cameras, operators, software, battlefield internet, electronic warfare, rapid manufacturing, repair workshops, training pipelines, data feedback, and tactical improvisation.
Ukraine plans to buy around 4.5 million first-person-view drones in 2025 — more than double the previous year's rate, with 96 percent sourced from domestic manufacturers.⁴ Ukraine's National Security and Defense Council says the country's industry can now produce more than 8 million FPV drones per year.⁵ Drones have moved from novelty to mass industrial weapon.
CSIS reported that vehicle movement is difficult within about 15 kilometers of the front line.⁶ RUSI describes a "wall of drones" creating an attrition belt of roughly 30 kilometers in some sectors.⁷
The sky itself has become a minefield.
But Ukraine also shows the limits of worshipping the machine. Russian counter-drone systems, electronic warfare, jammers, and hardened positions have improved. Many drones never reach their target, and successful drones work best when combined with mines, artillery, missiles, and infantry. RUSI warns that drones should extend traditional firepower, not replace it.⁷
The weapon matters. The system matters more.
Ukraine's most spectacular drone operations prove the point. In Operation Spiderweb on June 1, 2025, Ukrainian operatives concealed drones inside wooden modular cabins loaded onto cargo trucks, drove them near Russian air bases, and launched them against strategic aircraft deep inside Russia. Ukraine said 117 drones were used, striking more than 40 high-value aircraft — including strategic bombers — across five bases.⁸ CSIS described it as a milestone in asymmetric warfare: cheap drones, covert logistics, deception, remote communications, and precise targeting, working together.⁹
That was not just a drone strike. It was Fortitude with rotors.
Iran's Shahed-136 makes the cost argument in hardware: roughly 2,000 kilometers of range at an estimated $20,000 to $50,000 per unit.¹⁰ In April 2024, Iran launched 170 drones, 30 cruise missiles, and 120 ballistic missiles at Israel in a single salvo — not to destroy everything, but to force a defender with expensive interceptors to spend them against cheap munitions.¹¹ That arithmetic now defines modern air defense from the Black Sea to the Gulf.
Here is the part that should trouble Western defense planners.
The country that built the Mulberry harbor is still organized around platforms.
The United States defense establishment remains structured around major capital assets — aircraft carriers, nuclear submarines, fifth-generation fighters, large surface combatants. These are the weapons that win procurement battles in Washington. The Pentagon's Replicator initiative, launched in 2023, recognized the problem and aimed to field attritable autonomous systems at scale. But recognition and transformation are different things. The acquisition system that takes years to certify a component change on an F-35 cannot easily pivot to buying a million drones, building the software to guide them, or fielding the repair networks to sustain them.
