Filin Cruise Missile: Why Ukrainian Drone Experts Are Worried

Russia’s new Filin cruise missile has Ukrainian drone experts uneasy. Ukraine’s military intelligence agency, HUR, says Russian forces began using it at the end of summer 2026. It is cheap, partly 3D-printed and fast. Serhii “Flash” Beskrestnov and Serhii Sternenko, both former drone advisers to Ukraine’s defence ministry, say it could prove a bigger problem than the jet-powered Shaheds that have dominated Russian strikes so far.

HUR describes an 11-foot, ground-launched missile with a carbon and fibreglass body, some parts of it 3D-printed. Russia claims a top speed near 500 mph (about 800 km/h) and a range of 745 miles (1,200 km). That beats Geran-5, Russia’s fastest jet-powered drone, which tops out at 370 mph. The Filin cruise missile can fly very low or climb to 3.7 miles. 

It reportedly comes in two versions, with 50 kg and 100 kg warheads. Its Russian-made R500 engine sits alongside foreign parts, and HUR counts 22 Chinese and 35 American components. The estimated price is $150,000, about a sixteenth of a Kh-101 cruise missile. Some reports say it can also be launched from drones and helicopters, which conflicts with HUR’s ground-launch description.

Sternenko wrote on Telegram that mass use of such weapons is coming soon. In his view, Ukrainians will remember the jet-powered Shaheds as a small problem by comparison. The worry is volume, not any single missile. A low, fast, cheap weapon is hard to spot and costly to stop, and it forces Ukraine’s air defences to spend expensive interceptors on a $150,000 target. Ukrainian drone experts are sounding the alarm early, but the performance figures come from Ukrainian intelligence and Russian claims. None of it is independently verified.

HUR sees Filin as part of a wider shift toward cheap, jet-powered, ground-launched strike weapons built at scale. Watch for larger salvos and for whether Ukraine’s air defences adapt to low-flying targets. Also watch whether Western and Chinese parts keep reaching Russian production lines. Independent confirmation of the Filin cruise missile’s real speed and range will show how serious the threat is.
