Ukraine’s newest weapon drops from a balloon at 12 kilometers altitude, cuts its own guidance to defeat Russian jammers, and drifts silently into Russia on prevailing westerly winds. It is called DART. And it may change how Kyiv conducts long-range strikes.
Ukraine has unveiled a striking new addition to its deep-strike arsenal: the DART missile, a balloon-launched precision weapon designed to be immune to Russian electronic warfare. Developed by the Ukrainian company Center of Innovative Technologies Program, the system represents a novel approach to penetrating Russia’s increasingly dense air defense and jamming environment.
The mathematics of altitude and cost are surprisingly simple. A stratospheric balloon carries the 1.84-meter, 13-kilogram missile to between 12 and 18 kilometers (roughly 7 to 11 miles) above the ground. At that altitude, prevailing winds in the northern hemisphere blow reliably from west to east. That geographic fact works in Ukraine’s favor. Balloons launched from Ukrainian-controlled territory drift toward Russia, not away from it. By contrast, Russian balloon efforts such as the Barrazh-1 stratospheric platform face the opposite problem: their balloons drift back over Russian territory.
Once the balloon reaches a suitable release point, which can be 100 miles or more inside Russian airspace, the DART drops. Its satellite navigation system guides the missile during the initial phase of its descent. But at approximately 6 kilometers (roughly 4 miles) altitude, the onboard navigation shuts off and a solid-fuel engine kicks in. From that point forward, the missile follows a fixed, precomputed ballistic course to its target. There is no radio link, no GPS signal, and no datalink to intercept. Russian electronic warfare systems, which have proven effective against GPS-guided munitions throughout the war, simply have nothing to jam.
The warhead is configurable between 3.5 and 10 kilograms (3.5 to 10 kg). One variant scatters conductive graphite filaments designed to short out electrical transformers and substations, effectively weaponizing a power grid’s own infrastructure against it. This mirrors a technique used in earlier conflicts but refined here for precision delivery from a balloon-launched platform.
The strategic logic behind DART aligns with a broader Ukrainian campaign that President Volodymyr Zelenskyy has described as “long-range sanctions.” By striking oil depots, logistics hubs, airfields, and power infrastructure deep inside Russia, Ukraine aims to impose a rising cost on the Kremlin’s war machine and compel Moscow toward negotiations. Balloon-launched systems fit naturally into this strategy because they are cheap, difficult to detect on radar, and capable of loitering at altitude for extended periods before releasing their payload.
Ukraine has already launched more than 1,000 balloons across the border for surveillance and decoy purposes. Some have drifted as far as Moscow. Balloons cost roughly $200 each, and they have been used to bait Russian S-300 and S-400 surface-to-air missiles that cost approximately $1 million per interceptor. The combination of low-cost decoys and increasingly capable strike payloads creates a dilemma for Russian air defense commanders: expend expensive interceptors on cheap balloons or risk letting actual weapons through.
The DART missile has not yet cleared official codification by Ukraine’s Ministry of Defense, but developers say the process is underway. Future variants could include a ballistic missile configuration and a surface-to-air version, suggesting the underlying technology may find roles beyond deep strike.
The DART does not operate in isolation. In May 2026, Ukraine demonstrated the Hornet, an AI-guided strike drone produced by Perennial Autonomy (founded by former Google CEO Eric Schmidt). The Hornet is also carried aloft by a balloon before release, roughly doubling its effective range from 93 miles to at least 186 miles. Perennial Autonomy was simultaneously awarded a $500 million contract by the U.S. Army for counter-drone technology, the largest such award in American military history. The convergence of balloon platforms, artificial intelligence, and EW-resistant guidance is reshaping the economics of aerial warfare.
Russia has not ignored the trend. Its Barrazh-1 program aims to develop a stratospheric balloon capable of carrying a 220-pound relay station to 65,000 feet. Built almost entirely from Russian-made components as a hedge against sanctions, Barrazh-1 faces the fundamental geographic problem that its balloons would drift away from Ukraine, not toward it, due to the same prevailing winds that advantage Ukraine.
For now, the DART gives Ukraine an asymmetric tool that is hard to detect, harder to jam, and cheap enough to manufacture at scale. In a war where electronic warfare has often neutralized expensive Western precision munitions, the simplest workaround may be a balloon and a missile that knows its target well enough to turn off its own navigation before the enemy can interfere.
