Ukrainian Defense Intelligence has identified a variety of foreign electronic components in a nearly intact sample of Russia’s latest cruise missile, the K5-K, revealing significant reliance on American technology. The K5-K, an upgraded version of the Geran-5 jet drone, was reportedly deployed by Russia against Ukraine starting in early fall 2026.
Among the 93 foreign electronic components found in the K5-K, 52 are manufactured by U.S. companies, alongside 10 each from China and Switzerland. Notably, the components included digital signal processors from Texas Instruments and inertial modules from Japan’s Murata, which Russia is known to try to obscure.
Details on the K5-K Missile
The K5-K represents a more compact missile compared to its predecessor, measuring 4 meters in length and a wingspan of 3 meters. Its operational parameters have also improved, with a maximum altitude capability rising from 5 to 6 kilometers. The missile has a cruising speed of 450 kilometers per hour and can reach speeds of up to 1,000 kilometers per hour during certain maneuvers. Its operational range remains at 1,000 kilometers, while the warhead weighs 90 kilograms. A thermobaric warhead, which is more powerful than conventional ones, was identified in the studied sample.
This missile is equipped with the “Susanin” navigation system, which has also been observed in Russia’s Geran-4 drone. This system utilizes terrain imagery matched against stored reference images to navigate accurately. The image-processing unit is built on a Chinese microcomputer model known as the Coke Pi, while the drone’s engine, a TRD-200 turbojet, is assembled in Russia’s Alabuga with components sourced from China.
In a response to these developments, the Ukrainian Defense Intelligence has posted an interactive 3D model and a detailed list of the missile’s components on its War&Sanctions portal. They emphasize that the presence of these foreign parts indicates the extent to which Russia’s arms manufacturing relies on imports, which could be restricted by tighter sanctions.
As Ukraine continues to enhance its air defense capabilities, it has reportedly increased its effectiveness against Russia’s Geran-4 drones, successfully downing nearly 60% of them, with an even higher interception rate of up to 80% during specific attacks. Nevertheless, as the K5-K introduces a new threat, both Ukraine and its allies are urged to prepare effectively to avoid the tactical surprises encountered with the previous drone models.
