Ukraine is building a sea-facing layer of air defense along its southern coast, Kyrylo Liukov, head of the unmanned technologies department at the Serhii Prytula Foundation, wrote in a column for RBC-Ukraine. Winged interceptors now reach the Russian spy drones that guide strikes in the south.
Russia's nightly drone strikes on Ukrainian cities have turned air defense into a race to close every corridor Russia can fly through, over land first and now over the open sea. Kyiv does it with cheap interceptors rather than costly missiles, and keeps having to chase Russian workarounds. The sea was the stretch air defense could not reach, and it is where Russia keeps the spotters that make its Shahed swarms steerable.
Land and sea are two different fights
Defending the sky over land and over open water are two different problems, Liukov wrote. Multirotor copters are fast and simple to launch near the coast, but past roughly 25 km offshore, a multirotor is almost useless. Russia builds its mission routes so that drones cross dozens of kilometers over sea before they turn toward Ukrainian targets. Fixed-wing drones close the gap. Built like gliders, they loiter for over an hour and hold a link at 40 km and beyond, helped by an open radio horizon that land's terrain and buildings deny them.
Recon drones are the priority target for a reason. Beyond spotting and confirming hits, they work as relays in a MESH network for a group of strike drones. In that setup, Russian crews can steer Shaheds by hand right up to the moment of impact, Liukov wrote.
Southern units recently set three distance records with foundation-supplied interceptors. The 18th aviation commandant's office of Air Command South downed a Russian Orlan-30 reconnaissance drone 110 km out. It used a Wovkulaka Spitfire interceptor, the longest kill on record for that system.
The 12th Separate Special Purpose Center set the other two, flying a system from the miltech company TechnoTaras: an Orlan downed at 86 km, and a 145 km hunt measured from the takeoff point that held a stable digital link the whole way, Liukov wrote. That leaves Russia's drones exposed much farther from shore than its planners assume, he added—and if such results become routine, Russia has to pull its transit routes farther out still.
The Maiachnia beacon line
A less obvious problem was navigation, not shooting. A drone flying without GPS steers by landmarks, and over open sea, there are none. Late last year, the foundation, the 12th Separate Special Purpose Center, and TechnoTaras launched a project called Maiachnia. It strings radio beacons on the Skyline system along the coast from Ochakiv to Izmail. The beacons work on their own and keep backup power, tied to a central network that operators can adjust remotely. An operator can then track the drone even under GPS jamming, bad weather, or a temporary loss of link, and bring it home. More than five southern units now fly the foundation's winged drones.
The real stakes sit offshore—the southern ports and the Black Sea grain corridor that Russian drones threaten and that land-based copters can barely reach. Keeping Russian drones farther offshore would buy room there. But Russia is scaling up a faster, jet-powered Shahed, and the interceptor answer to it is early—so the offshore edge just won will have to be defended again.
