The KAB-500Kr is an electro-optical TV-guided fire-and-forget bomb developed by the Soviet Air Force during the 1980s. The seeker employs a gimballed daylight television imaging sensor positioned under a wide-angle glass dome. Guidance is provided by Scene Matching Area Correlation technology, allowing the system to engage low-contrast targets by referencing the contrast of nearby terrain features or objects. The standard configuration utilizes a hardened, armor-piercing warhead designed for use against reinforced concrete. The KAB-500-OD variant is equipped with a fuel-air explosive warhead, while the KAB-500S-E version utilizes satellite guidance. A training version is designated KAB-500Kr-U. Technical elements of the system are also applied to larger munitions, such as the KAB-1500Kr. The weapon remains in service with the Commonwealth of Independent States (CIS) and has been exported to several countries.
