The KAB-500Kr (Correctable air bomb - 500 kg) is an electro-optical TV-guided fire and forget bomb developed by the Soviet Air Force in the 1980s. It remains in service with the CIS and various export customers.
The KAB-500Kr is analogous to the American GBU-15 weapon. It uses a standard Soviet/Russian FAB-500 general-purpose bomb, with a nominal weight of 500 kg (1,100 lb), as a warhead, adding a low-light television seeker and guidance fins to turn it into a guided, unpowered glide bomb.
The bomb is 3.05 m (10.0 ft) long and weighs 520 kg (1,150 lb), of which 380 kg (840 lb) is a hardened, armor-piercing warhead capable of penetrating up to 1.5 metres (4 feet 11 inches) of reinforced concrete. The weapon's seeker can lock onto a target at ranges of up to 15 to 17 km (9.3 to 10.6 mi), depending on visibility. The KAB-500-OD variant is equipped with a fuel-air explosive warhead. The technology of KAB-500Kr is also used for larger bombs, such as KAB-1500Kr based on the 1500 kg class FAB-1500 iron bomb.
