The newest Russian glide bomb, Drel, has passed all tests. Serial production of the cluster bomb will start in 2024 at one of the Russian military factories. If you are interested in Russian bombs and missiles, as well as their use, links to the video are in the comments to the video. The PBK-500U SPBE-K glide bomb was developed by NPO Basalt and is designed to destroy armored vehicles, ground-based radar stations, control posts and enemy air defenses. It is expected that this aerial bomb will be almost impossible to recognize on radars; how the designers implemented this is not reported. The PBK-500U “Drill” air bomb glides towards the target and opens over it at the right moment. The bomb is guided using GLONASS. The bomb consists of 15 self-aiming combat elements. If the destructive element does not work on a given target, it self-destructs after a certain time. Each self-aiming combat element is a compact autonomous system capable of independently studying the ground situation, searching for targets and hitting them. The combat element contains a cumulative warhead capable of penetrating at least 70 mm of homogeneous armor, according to some sources, more than 100 mm. The ammunition can be used regardless of weather conditions and does not require the aircraft to enter the air defense zone. The mass of the bomb is 540 kg, length - 3100 mm, bomb release height up to 14 km, range of use up to 50 km. The maximum deviation from the target is less than five meters. The price of the bomb is unknown. Work on the Drill bomb continues; it will be produced in several modifications.
