On November 7, Ukraine's President Zelensky reported that Russia increasingly uses North Korean KN-23 ballistic missiles to strike Ukrainian cities. These missiles leave a distinctive fiery trail, known as a comet tail, during their final flight phase, which is linked to their design and guidance system. The KN-23 is a short-range, single-stage missile with a solid fuel engine, featuring a unique elongated body and specialized compartments for satellite navigation. The fiery trail may result from various physical processes, including the missile's movement through denser atmospheric layers and structural destruction during re-entry.
