Ukraine’s ‘Flat War’: Innovation Drives Drone warfare Success

Updated June 06, 2025

Facing a formidable⁤ challenge in the ⁣fall of 2022, Kyiv sought a‍ solution to Russian drone attacks. Iranian Shahed‍ drones, arduous​ to detect ‍by radar due to their‍ low altitude and stealthy design, were bombarding‍ Ukrainian cities.

Ukrainian engineers devised a ‌creative⁣ workaround: ‍a network of 9,500 microphones, attached to cell phones and mounted on poles, now blankets the country. This​ system, known as Sky Fortress, tracks incoming Shahed drones by sound and⁢ relays the data to ​soldiers who‌ then shoot down the slow-moving aircraft. The ⁤entire ⁤network costs less than a pair of Patriot missiles.

This approach reflects a broader shift in Ukraine’s military ⁤strategy,⁤ dubbed “flat war,” which prioritizes⁢ cost-effectiveness and empowers soldiers and entrepreneurs ‍to develop innovative solutions. This strategy emerged⁢ from the need to counter a larger, better-resourced enemy.

Operation Spiderweb,a recent drone attack⁤ on ‍Russian air bases,exemplifies‍ this approach. The operation, which appears to have seriously damaged Russia’s strategic bomber fleet, highlights Ukraine’s ability ​to inflict significant damage at a ‌fraction of the cost ⁣of traditional military operations. Each ‍of the‍ 117 drones⁣ used in‌ the operation ‌cost approximately $1,000.

Decentralization is a key element of this strategy. Brigades recruit their own soldiers, work directly with ⁣companies to develop weapons, and even manufacture⁤ drones using 3D-printing facilities.‍ President Volodymyr Zelensky recently stated that Ukraine produced 2.2 million drones in 2024, with a target of more ‍than double that for the⁢ current year.

This decentralized approach ⁣fosters rapid innovation. Ukrainian tech experts ​developed an app allowing troops, spotters, and artillery units to coordinate⁢ attacks. ​The country has also made strides⁢ in adapting artificial ⁣intelligence to the battlefield. Some drones⁢ in Operation Spiderweb ⁣used AI to hit their targets.

Joyce Hakmeh, deputy director at Chatham House, noted that Ukraine’s advantage lies in its ability to outpace Russia in the innovation cycle by exploiting available solutions in ⁣innovative ways.

Ukrainian security services also operate at ⁢the cutting edge of flat war, prosecuting ‌covert actions ⁤against Russia. The Security Service of ⁣Ukraine (SBU) claimed responsibility ‌for the⁢ December killing ⁤of a Russian general in Moscow. The Ukrainian military intelligence agency (HUR)​ is believed to be behind the‍ 2023 killing of a former Russian submarine commander.

What’s next

The United⁣ States is studying Ukraine’s flat‌ war model. The Defense Department’s⁤ Replicator program, which ‍aims to produce ⁣swarms of cheap ⁤drones, and ⁤the Accelerate ⁢the Procurement and Fielding of Innovative Technologies initiative reflect Ukraine’s experience.
