Ukraine hits Russia’s second-largest refinery as fuel rationing spreads

Ukraine discovered that Russia's newly developed "Geran-5 K5-K" mini cruise missile contains numerous American components. The Ukrainian Defense Intelligence examined a nearly complete missile and identified 52 parts from US manufacturers, alongside 10 each from China and Switzerland among the 93 foreign components. Russia recently started using the upgraded K5-K modification against Ukraine in early fall 2026, finding the new design both more compact and faster than its predecessor.

The K5-K missile boasts an increased maximum altitude of 6 kilometers, a higher cruising speed of 450 km per hour, and the ability to accelerate to 1,000 km per hour in certain maneuvers. Its range remains at 1,000 kilometers, with a 90-kilogram warhead. Intelligence also identified a thermobaric warhead, a more potent variant, inside the studied sample.

The missile utilizes the "Susanin" system, which Ukraine's intelligence previously found in Russia's Geran-4 drone. This system employs terrain imagery for navigation, comparing live camera footage with reference images stored in memory to maintain the correct route. The image-processing block runs on a Chinese microcomputer called the Coke Pi.

The missile's engine, a TRD-200 turbojet, is constructed in Russia's Alabuga, with Chinese components assembled within it. The Ukrainian Defense Intelligence has published an interactive 3D model and the full component list on its War&Sanctions portal, emphasizing how Russia's weapon production increasingly relies on imported parts, which could be restricted under tighter sanctions.
