German defense AI firm Helsing has unveiled Contra, an AI-run air defense system and two interceptor missiles designed to chase Russia’s jet-powered Geran drones, the company announced on 26 October. Officials pitch it as cheap, but it won’t reach the market this winter.

That leaves Ukraine on its own defenses as Russia shifts to jet drones. By early October, jet models made up about 40% of Russian drone launches, and Ukraine’s own interceptors for them won’t arrive in needed numbers before late November, Air Force Deputy Commander Yurii Cherevashenko said.

Two missiles, one AI brain

Contra is the command layer of air defense: it links radars and other sensors, tracks incoming drones and missiles, and assigns a weapon to each target, while people keep control over decisions, Helsing said. Besides the company’s own missiles, it can also use other firms’ interceptors, lasers, guns, or nets. AD-1 Inferno is jet-powered and designed to loiter, swarm, and re-engage targets, while AD-2 Ambush, a solid-fuel rocket, is designed to reach Mach 2.5, over twice the speed of sound, and a range of more than 20 km, the company said.

Inferno, with a 700 km/h speed and a 20-km range, would be the everyday shooter. Ambush would handle “leakers,” drones about to hit the ground, said Maxwell Adams, Helsing’s senior product director. Each shot should cost under $100,000, company officials said.

Built for the faster Gerans

Ukraine once downed 90% of Russia’s slower, propeller-driven Gerans, copies of Iran’s Shahed, Defense News reported. Russia has since fielded thousands of jet Geran-4s and Geran-5s flying at 400–700 km/h, and almost half now get through, Helsing co-founder and co-CEO Gundbert Scherf said.

Ukraine’s own nightly rates swing widely. On 28 September, President Zelenskyy put the shoot-down rate for jet drones at 57%. Overnight on 7 October, it exceeded 82%, National Security and Defense Council Secretary Ihor Klymenko said. Russian output of the two models has reached 4,000 a month, Helsing said, citing unspecified intelligence reports.

Helsing has signed one Contra contract, Scherf said, but the system is still in testing, and he expects it on the market in the second half of 2027. Ukraine already uses Helsing’s HX-2 strike drones. Scherf said they should be integrated into a system like Contra.

In a direct confrontation with Russia, European NATO states would likely be even more vulnerable than Ukraine to swarms of Russia’s new jet-powered strike weapons, Fabian Hoffmann of the Norwegian Institute for Defence Studies (NIDS) argued in a 20 October op-ed for the Center for European Policy Analysis (CEPA). He calls them low-cost cruise missiles. Just three days earlier, Romania met what it believes were two of them over the Black Sea.

Romanian F-16 fighter jets shot down two jet-powered Geran-family drones over Romania’s territorial waters on 17 October, the Defense Ministry said. Interim Defense Minister Radu Miruță said they flew at about 450 km/h and were likely Geran-4s, the first of that type Romania had downed.

Faster drones for a faster war

Russia began using the Geran-4 in May in response to effective Ukrainian interceptor drones, Ukraine’s military intelligence (HUR) said, adding that it reaches up to 500 km/h. By June, those interceptors were downing about half of slower Shahed-type drones, defense adviser Serhii Beskrestnov estimated.

Hoffmann traces the shift to the Geran-3, a model Ukraine recovered intact in 2025. In his account, a Chinese JT80 turbojet roughly doubled its speed, from 185 to 350 km/h. However, he puts newer models, including the Geran-4, at 600 km/h or more, above HUR’s figure for that model.

By his estimate, each costs $150,000–$250,000, against about $50,000 for a long-range drone. Still, from Russia’s perspective, he wrote, that buys a significantly higher chance of getting through.

Engines are the bottleneck

Hoffmann argues defenses must match the threat’s speed, for example with jet-powered interceptor drones. Ukraine already fields some. On 4 October, President Zelenskyy said its Bars interceptors had shown the highest percentage among Ukrainian interceptors, about 30% of targets, according to Militarnyi. One unit destroyed five aerial targets with five Bars interceptors, Defense Minister Yevhenii Khmara later told journalists. He also called aviation one of the most effective tools against jet drones.

Hoffmann’s concern is scale. Jet engines are in short supply, he wrote, because too few European and US suppliers can meet demand. Ukraine’s Defense Industry Council flagged a shortage of such engines for its drones in April. In his view, gun systems and higher-end missile defenses are too scarce or too costly to fill the gap.
