Novel interceptor drones bend air-defense economics in Ukraine’s favor

KYIV, Ukraine – One in every three Russian aerial targets destroyed over Ukraine is now brought down not by a missile or a gun — but by interceptor drones that each cost less than a used car, Ukraine’s air force says.

Over the capital, the new class of interceptors is even more effective. Drones were credited with more than 70% of Shahed downings in February, Ukraine’s Commander-in-Chief Oleksandr Syrskyi announced on Tuesday.

The math tells the story: A single Patriot interceptor costs over $3 million, a NASAMS round slightly over $1 million — and each Shahed costs Russia as little as $35,000 to manufacture, according to the Center for Strategic and International Studies.

That puts Ukraine on the wrong side of an approximately 85-to-1 cost exchange every time it uses a Patriot to defend against a drone.

But at $3,000 to $5,000 apiece and an average success rate over 60%, interceptors are now changing the calculus of war, Zelenskyy told Fox News late last year.

These drones, a weapons category that barely existed a few years ago, have become the fastest-growing layer of Ukraine’s air defense.

“We are the first in the world to have a system of destroying drones with drones in the air,” Col. Yuriy Cherevashenko, deputy commander of UAVs for air defense of the Ukrainian Air Force, said in a video marking the fourth anniversary of Russia’s full-scale invasion.

Facing an unrelenting adversary whose economy dwarfs its own by nearly tenfold, Ukraine had no choice but to outthink rather than outspend, and interceptor drones — mobile, cheap and scalable enough to answer Russian mass production with Ukrainian ingenuity — have emerged as their biggest bet.

Now, what began as battlefield improvisation has become a deliberate war strategy.

“Drones now occupy a wide segment of the air defense system,” Cherevashenko said. “In the future, they will be perhaps the most numerous means of destroying aerial targets.”

Their rapid development over the last year tracked Russia’s escalating use of Iranian-designed Shahed attack drones, which by mid-2025 were arriving in record-breaking waves that overwhelmed Ukraine’s missile-based air defenses faster than Western allies could resupply them.

“We needed to supply a lot of interceptors this year, because without them, the winter would have been even harder for Ukraine,” Alona Zhuzha, director of digitalization at Ukraine’s newly established Defense Procurement Agency, told Military Times.

The National Security and Defense Council (NSDC) said the country produced 100,000 interceptor drones in 2025 and reported that production capacity has grown eightfold compared to the prior period.

Frontline units received an average of over 1,500 interceptor drones per day in December and January — up from about 1,000 per day during the previous period, the MOD said at the beginning of the year.
