Fighting in Ukraine is giving rise to a new kind of drone warfare: hit-to-kill intercepts

• The grinding Ukraine war has seen a rise in hit-to-kill drone interceptions of other drones.
• Kyiv and Moscow are increasingly using drones to take out enemy systems above the battlefield.
• This new tactic is pushing Ukraine to develop drones specifically for interceptor roles.

In the contested skies above Ukraine, a new kind of warfare is rapidly emerging as drones are increasingly sent on new attack missions. Their targets aren’t armored vehicles or fighting positions — they are other drones.

Combat footage from the war in Ukraine has repeatedly captured these hit-to-kill intercepts in which a cheap drone slams into another unmanned aircraft. This practice is a cost-effective air-defense option that both the Ukrainians and Russians are using and intently pursuing.

Mykhailo Fedorov, Ukraine’s minister for digital transformation, posted on Telegram in April that his country was on the hunt for interceptor drone solutions to shoot down Russian surveillance assets, the front-line eyes for strike drones and Russian artillery, “without wasting air defense assets.”

Nataliia Kushnerska, a senior executive in Ukraine’s defense industry, told Business Insider that using uncrewed systems in this way “marks the emergence of an entirely new segment of modern warfare — drone-on-drone combat.”

A new tactic in the evolving drone war

Drones have dominated the battlefield throughout much of the Ukraine war, being used for land, sea, and air missions. Cheap first-person view (FPV) drones are frequently used to carry out pinpoint strikes on enemy armor and troop positions, while larger systems collect intelligence.

But as the war has dragged on, drones have increasingly been used in an air-defense role to take down enemy uncrewed aerial vehicles (UAVs) carrying out reconnaissance and attack missions. These aerial engagements can, at times, resemble the fierce dogfights of the World Wars.

An outfit that makes combat FPV drones posted in August that its modified drones had taken out 100 Russian UAVs. The Wild Hornets, as the operation calls itself, shared footage of some of the interceptions.

Kushnerska, the chief operating officer of Brave1, a Ukrainian government platform that facilitates innovation within the country’s defense industry, said interceptor drones have become “one of the innovations of this war.”

The tactic, she said, makes it more difficult for Russia to operate its drones deep behind the front lines and collect data to facilitate missile and drone strikes on Ukrainian positions, which has been a real challenge for Ukraine as Russia pushes to expand its reconnaissance strike complex. This also awards Kyiv more flexibility to carry out its military operations and maneuvers.

Kushnerska said Ukraine was the first to use drones to intercept Russian reconnaissance UAVs, but Moscow has since adapted to the tactic and found ways to evade the interceptors. Now, efforts are underway to improve the systems so they remain effective.

It is the latest iteration of what a senior Ukrainian official previously described to BI as a cat-and-mouse game between Kyiv and Moscow, where each side is constantly attempting to one-up the other in developing drones and other war-related technology.

Samuel Bendett, an expert on drones and Russian defense issues with the Center for Naval Analyses, told BI Moscow is similarly using FPV drones to take out Ukrainian systems and that Russia has also equipped its drones with defenses against interceptor drones, such as electronic-warfare jamming systems.

Bendett said that the Ukrainians “have gotten very successful in fielding their FPV drones against Russian ISR assets, and the Russians have gotten successful, up to a point, with using their FPV drones to go after Ukrainian heavy quadcopter UAVs.”

Interceptor drones are limited in range and altitude and often carry less explosive power than more traditional air defenses like missiles. Drones provide Ukraine and Russia with an alternative way to take down aerial threats, one in which the cost of the intercept is often less than that of the system being targeted.

Kushnerska said an interceptor drone typically costs between $2,000 and $4,000. An air-defense missile, on the other hand, could cost hundreds of thousands — or even millions — of dollars. Using drones reduces dependency on more expensive munitions and frees up Ukraine’s air-defense units to focus on the bigger threats like Russian aircraft and more deadly cruise and ballistic missiles.

Pursuit of more interceptor drones

For the Ukrainian soldiers tasked with intercepting Russian drones, it’s a dangerous mission.

One drone operator in the Ukrainian military told BI that he operates from trench shelters very close to the front lines. He said the pilots are priority targets for Russia, which will use “every single thing at its disposal” to take them out.

The Ukrainian operator said that drone-on-drone combat is increasing. He said he sometimes uses interceptor drones up to five times a week. But Ukraine needs more of them.

Kyiv has taken steps to procure more of these interceptor drones. Last month, for instance, a Ukrainian drone engineering company announced it had completed testing for a new FPV drone designed to take down Russian reconnaissance UAVs, like the Orlan, and was ready for military use.

But there’s still more to be done. Valeriy Romanenko, a former air-defense officer who’s now a researcher at Ukraine’s State Aviation Museum, told BI that Kyiv’s interceptor drones are good for slower reconnaissance UAVs at lower altitudes.

However, he said, Kyiv ultimately needs faster interceptor drones to take down Russia’s deadly attack drones, like the notorious Shahed-136. In October alone, Moscow fired around 2,000 of these systems at Ukraine, according to Western intelligence.

The Wild Hornets have been working on a new “Sting” UAV to effectively combat the Shaheds, but it’s a work in progress.

This hit-to-kill intercept tactic has implications well beyond Ukraine and could be used in future conflicts, too. Mick Ryan, a retired Australian Army major general and strategist, said the use of drones for interceptions will likely be a lasting element of military operations.

“This is a trend that’s here to stay unless there is some fundamental breakthrough in very low-cost anti-drone systems, and we’re not seeing that at this point,” he told BI. “I think this is an enduring kind of capability that many militaries should be looking at.”
