The KAB-500KR 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 (1,102 lb), as a warhead, adding a low-light television seeker and guidance fins to turn it into a guided, unpowered glide bomb.
